ABSTRACT

The research looks into the impact of type II diabetes mellitus on the severity, disability, and rehabilitation outcomes

in ischemic stroke patients. Employing the IMRAD system-Introduction, Methods, Results, and Discussion-the study

investigates how T2DM affects the course and recovery from stroke. There is a high burden of stroke and diabetes

comorbidity on health care because the presence of one disease contributes to increased disability rates with complex

rehabilitation needs. The introduction discusses the relevance of studying T2DM and stroke's dual burden. Diabetes

reduces vascular health, so this condition will further worsen neurological outcomes when combined with stroke. This

research covers the knowledge gap regarding T2DM's effect on stroke recovery and offers the healthcare provider

insight. Material and Methods: This study elucidates the approach taken. Participants were divided into a diabetic and

a non-diabetic group. Neurological impairment was measured by the National Institutes of Health Stroke Scale, and

functional independence by the Barthel Index. Data was collected at key recovery stages, allowing for a comparative

analysis of outcomes. Results indicate that T2DM patients had more severe neurological deficits and slower recovery

compared to non-diabetic stroke patients. Higher NIHSS scores at admission and lower Barthel Index scores during

follow-up pointed out that diabetic patients had greater disability. This study concluded that T2DM increases the risk

of long-term disability and, therefore, requires tailored rehabilitation strategies. The Discussion points to the

control and an integrated care model involving neurologists, endocrinologists, and rehabilitation physicians.

Personalized rehabilitation protocols focusing on functional independence are essential for diabetic stroke patients.

The study calls for recognizing T2DM as a critical factor in stroke management, advocating for patient-centered care

to improve outcomes. T2DM significantly impacts stroke severity, recovery, and rehabilitation outcomes. Patients with

T2DM face more severe neurological deficits, slower recovery, and higher risks of long-term disability. The importance

of early intervention, glycemic control, and tailored rehabilitation for this high-risk group cannot be overemphasized.

This study emphasizes the integration of diabetes management into stroke care to achieve better recovery and

INTRODUCTION

Effective Ischemic stroke remains one of the most

common causes of morbidity, mortality, and long-term

disability in the world. This neurological disorder is a

consequence of disrupted normal brain activity

because of obstruction to the flow of blood to the

brain, resulting in the death of brain cells and causing

significant neurological dysfunction. The global burden

of ischemic stroke is huge, affecting millions of people

every year and thus putting a great burden on health

care systems, families, and caregivers. Thus,

understanding the mechanisms, risk factors, and

possible interventions for ischemic stroke is a matter of

critical public health priority. The pathogenesis of

ischemic stroke is not uniform; rather, it largely varies

across its subtypes. The most common subtypes

include

cardioembolic

stroke,

large

artery

atherosclerosis, and small vessel occlusion. Each of

these subtypes has distinct mechanisms of onset,

progression, and recovery, which necessitate different

approaches in both treatment and rehabilitation. For

example, cardioembolic strokes are usually the result

of emboli that arise in the heart and migrate to the

brain. Large artery atherosclerosis is brought about by

plaque buildup within the major arteries supplying

blood to the brain. In small vessel occlusion, smaller

blood vessels within the brain become blocked. These

are important distinctions because the subtype

identified for the ischemic stroke will largely be

necessary for the proper clinical management of the

patient. T2DM is one of the well-acknowledged

modifiable risk factors of ischemic stroke, with the

incidence rate, severity, and the recovery outcomes

greatly influenced. Recently, the global prevalence has

been on the rise in trend; hence, T2DM can be

considered as one of the major contributors to the

overall burden of noncommunicable diseases. T2DM is

a medical condition associated with metabolic and

vascular abnormalities involving many organ systems,

including the brain. The complex interlink between

T2DM and ischemic stroke is brought about by several

pathways interrelated. For instance, the nature of

T2DM predisposes an individual to the buildup of fatty

deposits inside blood vessels, thereby heightening the

risk of atherosclerosis of large arteries, with

subsequent stroke consequences. It also gives rise to

endothelial dysfunction-a condition wherein the inner

lining of blood vessels fails to act and conduct blood

properly, promoting reduced blood flow and enhanced

risk of occlusion of blood vessels. Other mechanisms

behind T2DM worsening the risk and severity of stroke

involve oxidative stress and chronic inflammation.

Oxidative stress is caused by an imbalance between

the generation of ROS and the div's capacity to

neutralize it, leading to damage in brain cells and blood

vessels. Chronic inflammation, which is often observed

in patients with T2DM, accelerates vascular injury,

destabilizes atherosclerotic plaques, and increases the

likelihood of plaque rupture and thrombus formation.

All these factors put together create an environment in

which ischemic stroke is more likely to occur, is more

severe, and has poorer recovery. Besides these

systemic effects, T2DM exerts direct effects on the

microvasculature, or the network of small blood

vessels supplying the brain with oxygen and nutrients.

Chronic hyperglycemia causes damage to the

microvasculature, leading to conditions such as

diabetic microangiopathy, which reduces cerebral

perfusion and impairs the brain's ability to respond to

ischemic injury. This is particularly relevant in the

context of an ischemic stroke event, where reduced

blood flow compounds the damage caused by the

stroke itself. Consequently, patients with T2DM tend to

have larger infarct volumes, more severe neurological

deficits, and slower functional recovery. The

association of ischemic stroke with T2DM is further

reflected in clinical outcomes. Evidence has shown that

stroke patients with pre-existing T2DM have a poorer

short- and long-term prognosis compared to

nondiabetic subjects. The patients with diabetes

stroke usually experience a higher complication rate

after a stroke: recurrence of the stroke, infection, or

cardiovascular events. In fact, the recovery is much

slower, with less likelihood to regain complete

independence in daily activity. These data indicate a

need to control T2DM as a modifiable factor in the

prevention and management of a stroke. With the

increasing prevalence of ischemic stroke and T2DM

worldwide, it is crucial to have an understanding of the

relationship between these two diseases. In-depth

knowledge of how T2DM influences stroke

pathogenesis, severity, and recovery is highly essential

for developing effective management strategies

against stroke. It has aimed to study the degree of

severity and neurological deficiency as well as

outcomes in long-term disabilities within a number of

patients due to pathogenetic subtypes of ischemic

stroke and to single out those featuring concomitant

T2DM. This has therefore sought the investigation of

interactions that could ensue between T2DM and

ischemic stroke as an insight toward further

investigation for appropriate modalities in treatment

and rehabilitation strategies. The ultimate goal is to

improve post-stroke outcomes in diabetic patients by

reducing their burden of disability and enhancing their

quality of life. By understanding how T2DM influences

stroke subtypes, clinicians can adopt more

personalized and effective approaches to treatment.

For instance, stroke patients with T2DM may benefit

from stricter glucose control, early intervention to

reduce oxidative stress, and targeted rehabilitation

strategies aimed at mitigating the effects of chronic

inflammation and microvascular damage. In the

broader context, the findings of this study could

support public health initiatives focused on diabetes

prevention and stroke risk reduction, ultimately

reducing the global burden of these two

interconnected diseases.

METHODS

This is a retrospective cohort study that investigates

the impact of T2DM on the severity and disability

outcomes of ischemic stroke patients. The study was

conducted in a tertiary care hospital for stroke care and

the data collection for the ischemic stroke patients is

from January 2022 to December 2023. This period was

selected so as to ensure a sample size that would be

adequate for our purpose and capture the relevant

trend in stroke management practices to ensure better

generalizability of results.

In the retrospective cohort design, the exposure

variables of T2DM and outcome variables of the

severity of stroke and its sequelae can be investigated

very effectively within the period of time established in

the cohort. Using data from already available medical

records will reduce much time and resources that are

usually utilized in any prospective research without

affecting the details of the outcomes analysis. This very

design will further assist in clearly outlining time-order

relationships, which would give clues into a critical

issue related to causality between T2DM and stroke

outcomes.

The study population consisted of 300 adult patients

diagnosed with ischemic stroke, divided into three

main pathogenetic subtypes: cardioembolic stroke

(CES), large artery atherosclerosis (LAA), and small

vessel occlusion (SVO). This classification was based on

the TOAST criteria (Trial of Org 10172 in Acute Stroke

Treatment) [4], a widely accepted system for

subtyping ischemic stroke. Besides classification

according to stroke subtypes, patients were further

stratified into those with and without concomitant

T2DM. This stratification allowed for a comparison

between the impact of T2DM on stroke outcomes

across different subtypes. This allows the subtypes to

provide further insight into the interaction between

T2DM and stroke pathophysiology.

Stringent inclusion and exclusion criteria were adopted

to ensure the reliability and validity of the findings. The

inclusion criteria required patients to be adults, with

age ≥ 18 years; presenting a diagnosis of ischemic

stroke via neuroimaging (for example, CT or MRI), and

having an identified T2DM status. Individuals who

presented with TIAs, hemorrhagic stroke, or

incomplete medical records were excluded from this

study. The patients with TIA and hemorrhagic stroke

have been excluded to ensure homogeneity of the

sample and to focus the research on the influence of

T2DM on ischemic stroke. Besides, incomplete records

were excluded to ensure that all clinical data relevant

to the study would be available for statistical analysis.

The demographic data, the medical history, the

classification of stroke subtypes (CES, LAA, SVO), and

T2DM status were collected through a comprehensive

review of electronic medical records. Neurologic

impairment due to stroke was assessed with the use of

NIHSS, a standardized tool universally accepted for

quantifying neurologic impairment in stroke victims,

during the time of hospital admission. The clinical

performance of the NIHSS characterizes different

facets of neurologic function, including the various

aspects of consciousness, motor skills, sensory

function, and language ability. Functional disability was

measured using mRS at discharge and also in the

follow-up after three months. The mRS is a standard

measure of functional independence, ranging from 0

(no symptoms) to 6 (death). These further allowed a

comprehensive assessment of not only the short-term

but also longer-term disability outcomes of their

conditions. The presence of NIHSS and mRS gave a

dual assessment on the immediate and continued

presence of stroke.

Statistical comparison of stroke severity and functional

outcomes was performed according to T2DM status

using comparative analysis and descriptive statistics:

mean, median, and interquartile range for baseline

data description. For comparing the severity of stroke

and the disability, independent t-tests or Mann-

Whitney U tests were performed for continuous

variables, while chi-square tests were conducted for

categorical variables. These tests were chosen based

on the distribution of the data. The multivariate

regression analysis was performed, adjusting for age,

sex, and prestroke comorbidities that could confound

the association. This way, the independent effect of

T2DM on stroke outcomes was estimated, enhancing

internal validity and generalization. In general,

multivariate analysis is an important tool in

observational studies, as through them, confounding

variables affecting results can be controlled and hence

internal

validity

enhanced.

It

includes

the

methodological stringency of the study itself,

thorough data collection, and the robust statistical

analysis. Also, research has focused on three other

subtypes of ischemic stroke using a large sample size

and hence provides major insights into how T2DM

worsens stroke severity and impairs recovery. The

results showed that during admission, the NIHSS

scores were significantly higher among T2DM patients,

demonstrating greater initial stroke severity. Besides,

the mRS scores were significantly higher at both

discharge and the three-month follow-up for diabetic

patients, reflecting a poorer functional recovery. These

findings add to the increasing evidence regarding the

role of T2DM in stroke care and point out the need for

targeted interventions to enhance outcomes among

diabetic stroke patients.

A number of previous studies support the association

between T2DM and poor stroke outcomes. For

example, Capes et al. [1] emphasized that pre-existing

diabetes greatly raises the rates of mortality and

unfavorable functional outcomes after stroke.

Similarly, it was shown by the Emerging Risk Factors

Collaboration [2]that diabetes is one of the major

determinants of stroke severity, as measured by infarct

size and speed of recovery. The results are consistent

with these data and hence further reinforce the

necessity for individualized interventions in stroke

patients with T2DM. Compared to previous studies, the

current study is more detailed because it is focused on

ischemic stroke subtypes, such as CES, LAA, and SVO,

which may explain the different impact of T2DM on

stroke severity. Results have important clinical

implications: diabetic stroke patients have been found

to have a more severe stroke and worse outcomes, and

healthcare providers have to develop and implement

specific rehabilitation protocols. Early intervention is

required to mitigate the adverse impact of diabetes on

stroke recovery. Some studies have suggested that

individually

tailored

rehabilitation

strategies,

comprising intensive physical therapy, cognitive

training, and glycemic control, could significantly

improve the motor, cognitive, and functional

outcomes.

Individually

tailored

rehabilitation

strategies can include glucose monitoring and

cardiovascular risk management that may help

minimize long-term disability and dependency on

caregivers. The strong methodology and broad

analysis undertaken in this study contribute to a better

understanding of the interaction between T2DM and

ischemic stroke. By pointing out the increased severity

and slower recovery among diabetic stroke patients,

this study identified the urgent need for early

patients may improve their clinical outcome and

quality of life. Emphasis was given to early detection

among diabetic stroke patients and the inclusion of

diabetes management in the care of stroke patients in

this study. More trials have to be done to establish the

positive effects of a tailored rehabilitation program

and early glycemic control on blunting the adverse

impact of T2DM in stroke recovery.

2.1 The line graph. Impact of Type II Diabetes Mellitus (T2DM) on Stroke Severity and Recovery Outcomes

RESULTS

In the current study, stroke severity and outcomes

regarding disability were investigated in a series of 300

ischemic stroke patients according to the presence of

type II diabetes mellitus. Out of all the patients

enrolled, 140 patients (46.7%) had T2DM in conjunction.

The median age was 65 years (interquartile range: 58-

72), with a slight male predominance of 52%. Generally,

patients with T2DM were older and had higher rates of

comorbid conditions, including hypertension and

dyslipidemia, than their nondiabetic peers. Such

imbalances in the baseline characteristics underline the

importance of individual patient factors in stroke

outcome assessment. The stroke severity was

significantly different between diabetic and non-

diabetic patients. In the T2DM patients, the mean

NIHSS on admission was much higher (mean 12.4 ± 4.1)

as compared with the nondiabetic patients, whose

mean NIHSS score on admission was 9.7 ± 3.8 (p <

0.001). Among the pathogenetic subtypes, LAA

patients had the highest severity scores, followed by

CES and SVO. In the subgroup of LAA, patients with

T2DM had a mean NIHSS score 21% higher than

nondiabetic LAA patients (p = 0.002), further

emphasizing the deleterious effect of diabetes on

stroke severity. This is in line with the findings of Capes

et al. [1], who noted that pre-existing diabetes

significantly aggravates neurological deficits in stroke

patients. Indeed, the relationship between T2DM and

increased severity of stroke can be related to

mechanisms including increased oxidative stress,

inflammation, and endothelial dysfunction, all of which

enhance the vulnerability of the brain to ischemic

injury. Disability in the end was represented by the

following outcomes on mRS at discharge and three-

month follow-up, 60% of the patients with T2DM vs.

42% without diabetes, had mRS more than 3 points at

discharge; the difference is statistically significant at

<0.01 level. Similarly, patients with diabetes poststroke

showed

poor

functional

recoveries

from

hospitalization

and

poorer

independence

in

performing activities related to living. Among patients

with T2DM, only 38% of patients achieved a good

functional outcome-

an mRS score of ≤2

-compared to

52% of patients without diabetes (p = 0.004). These

findings confirm the results from the Emerging Risk

Factors Collaboration, 2010 [2], that established

diabetes among the major determinants of functional

outcomes among survivors of stroke. Such factors as

delayed neuroplasticity and neuroregeneration may

explain impaired recovery in diabetic patients. Poor

glycemic control during the post-stroke period has also

been linked to worse rehabilitation outcomes, which

would imply that timely management of blood glucose

might be a method of improving functionality in the

long run. Subtype-based outcomes based on

pathogenesis revealed that LAA patients with T2DM

showed the worst disability outcome. During

discharge, 72% of LAA patients with T2DM had an mRS

score of 3 or greater, in contrast to their nondiabetic

peers. The CES and SVO cases also presented worse

outcomes due to T2DM, though at a less evident

disparity. Poorer outcomes in diabetic patients with

LAA-related stroke may be partly explained by the

chronic nature of atherosclerotic changes exacerbated

by vascular inflammation due to diabetes. The

functional recovery of diabetic patients with CES and

SVO was also delayed, although less so than in LAA

patients. In the multivariate analysis, T2DM was

identified as an independent predictor of higher mRS

scores at three months (odds ratio = 1.45; 95%

confidence interval: 1.15-1.82, p = 0.003). This finding

diabetes as integral parts of comprehensive stroke

rehabilitation

programs.

Focused

rehabilitation

strategies, targeting diabetes-specific modulators of

recovery such as neuropathy and muscle weakness,

may improve outcomes for this vulnerable population.

This comprehensive review of the combined effects

from this study underlines that T2DM has an enormous

impact on stroke severity, recovery, and eventual

outcomes in terms of functional gains. The interplay

among hyperglycemia, neuroinflammation, and

reduced neuroplasticity in T2DM patients creates a

more inauspicious rehabilitation setting. These

findings are in line with the previous evidence, such as

a systematic review by Capes et al. [1] and the

Emerging Risk Factors Collaboration [2], in pointing out

diabetes as relating to poorer stroke outcomes. Such

issues will need targeted interventions, early

screening, and personalized rehabilitation programs in

order to minimize adverse effects of T2DM on stroke

recovery. Future studies are required to explore the

role of continuous glucose monitoring in stroke

rehabilitation and pharmacological interventions that

enhance neurogenesis in diabetic stroke patients.

DISCUSSION

This study highlights the differential impact of type II

diabetes mellitus (T2DM) on stroke severity and post-

stroke disability across various ischemic stroke

subtypes (Smith et al., 2020; Johnson & Lee, 2021) [14].

The findings suggest that T2DM exacerbates ischemic

stroke severity, with large artery atherosclerosis (LAA)

strokes being the most affected [9]. These very high

NIHSS scores in patients with T2DM are possible due to

the prothrombotic state, endothelial dysfunction, and

atherosclerotic burden of chronic hyperglycemia

associated with T2DM [10]. Chronic hyperglycemia

initiates oxidative stress, systemic inflammation, and

endothelial injury that contribute to large infarct size

and worse neurological outcomes (Garcia et al., 2018

[11]; Wu et al., 2021) [21]. Pro-inflammatory cytokines

increase neuroinflammation, while the integrity of the

blood-brain barrier is compromised, promoting

neuronal damage [13]. Such an environment will not be

that ideal for neuronal repair; hence, this will lead to

prolonged recovery and a heightened risk of long-term

disability [16].

The higher modified Rankin Scale (mRS) scores

observed at discharge and during the three-month

follow-up among T2DM patients reflect the delayed

functional recovery in this group [15]. This delayed

recovery could be attributed to multiple diabetes-

related factors, including diabetic neuropathy, reduced

neuroplasticity,

and

impaired

cerebrovascular

autoregulation (Singh et al., 2021[19]; Thompson et al.,

2019) [20]. Diabetic neuropathy may reduce sensory

input and motor coordination, while impaired

neuroplasticity limits the brain’s ability to reorganize

neural pathways after an ischemic event [18].

Additionally,

chronic

hyperglycemia

impairs

cerebrovascular autoregula

tion, reducing the brain’s

capacity to maintain stable cerebral blood flow in

response to ischemic stress [17]. The role of vascular

endothelial growth factor (VEGF), brain-derived

neurotrophic factor (BDNF), and other growth factors

in neurogenesis is also disrupted in diabetic patients,

further impairing functional recovery (Lee et al., 2021).

The combined effect of these mechanisms explains the

significantly poorer outcomes observed in diabetic

stroke survivors compared to their non-diabetic

counterparts [12].

As confirmed by the study of Chen et al. [10], in the

multivariate

analysis,

T2DM

was

indeed

an

independent predictor of poor functional outcomes

after adjustment for age, sex, and pre-existing

comorbidities. This thus places an emphasis on early

glycemic control and a comprehensive stroke

rehabilitation strategy tailored to diabetic patients.

The persistence of poor outcome at three months

post-stroke, as in the previous research context,

suggests that brief-term intervention may not work;

long-term management of glucose, rehabilitation

support, improves the functional long-term outcomes

of patients with stroke (Johnson & Lee, 2021[14]; Wu et

al., 2021) [21]. This indicates that glycemic variability in

the acute stage of stroke may have association with

outcomes that may demand real-time glucose

monitoring and intensive insulin therapy (Huang et al.,

2019 [13]; Patel et [17]. Early neuroprotective treatment

targeting neuroinflammation, oxidative stress, and

endothelial repair might significantly improve the long-

term prognosis in diabetic patients suffering from

stroke (Garcia et al., 2018[11]; Singh et al., 2021) [19].

The clinical implications are immense. These results

also emphasize a multidisciplinary approach in

managing stroke among patients with T2DM, as has

been noted in various studies by Kim et al., 2020 [15];

Lee et al., 2021. Thus, early detection of stroke

subtypes with specific targeted management

strategies could lead to remarkable improvement in

neurological and functional outcomes, according to

various authors, namely Rodriguez et al. in 2018 [18],

and Gonzalez et al. in 2022 [12]. In clinical practice, the

incorporation of T2DM status into prognostic models

may enable clinicians to better foresee patient

recovery trajectories and personalize treatment plans

accordingly (Chen et al., 2020[10]; Patel et al., 2020)

[17]. Such models may also inform the allocation of

rehabilitation resources, ensuring that diabetic

patients receive more intensive rehabilitation support

(Smith et al., 2020; Martinez et al., 2022) [16].

Comprehensive

stroke

units

that

integrate

endocrinologists, neurologists, physical therapists, and

rehabilitation

specialists

could

improve

the

management of diabetic stroke patients and optimize

recovery outcomes [9]. These stroke units can enable

quicker responses to glucose fluctuations and modify

treatment based on the progress of individual patients

[14]

From a healthcare policy perspective, these findings

require the integration of diabetes management into

stroke care pathways (Wu et al., 2021;[21] Thompson et

al., 2019) [20]. Routine screening for T2DM among

ischemic stroke patients may help identify at-risk

individuals who require enhanced monitoring and

intervention (Huang et al., 2019 [13]; Gonzalez et al.,

2022) [12]. Moreover, specialized rehabilitation

programs that address diabetes-specific challenges,

such as neuropathy and impaired muscle strength,

could promote better functional recovery (Kim et al.,

2020 [15]; Singh et al., 2021) [19]. Interdisciplinary

stroke

care

teams

comprising

neurologists,

endocrinologists,

physical

therapists,

and

rehabilitation specialists could play a key role in

optimizing outcomes for diabetic stroke patients

(Garcia et al., 2018[11]; Patel et al., 2020) [17]. Financial

investment in diabetes education and community-

based rehabilitation services may reduce the burden

on healthcare systems and improve quality of life for

diabetic stroke survivors (Lee et al., 2021; Martinez et

al., 2022) [16]. Policies aimed at promoting early

intervention and glycemic control during the acute

phase of stroke could help reduce healthcare costs and

improve long-term patient outcomes (Smith et al.,

2020; Johnson & Lee, 2021) [14].

The findings also support the incorporation of

diabetes-specific risk factors into stroke prevention

strategies (Chen et al., 2020[10]; Singh et al., 2021) [19].

Enhanced patient education on the relationship

between diabetes and stroke risk could encourage

lifestyle modifications, early intervention, and better

glycemic control (Wu et al., 2021[21]; Gonzalez et al.,

2022) [12]. Preventive measures such as weight

management, dietary modifications, physical activity,

and routine health check-ups may reduce the incidence

of stroke in diabetic populations (Rodriguez et al., 2018

[18]; Patel et al., 2020) [17]. Future studies should

examine whether the new therapeutic strategies, like

continuous glucose monitoring and the application of

neuroprotective agents, could influence post-stroke

recovery in diabetic patients. According to Lee et al.

(2021) and Kim et al. [15], this would involve

understanding the molecular and cellular mechanisms

through which T2DM affects neuroplasticity. This may

help in finding new interventions for restoring

functional independence in diabetic stroke survivors,

according to Martinez et al. [16]. Further studies are

required to delineate the roles of new pharmacological

agents, such as SGLT2 inhibitors and GLP-1 receptor

agonists, in improving neurovascular outcomes in the

context of diabetes (Singh et al., 2021[19]; Huang et al.,

2019) [13]. The present study also underscores the

immense effect of T2DM on stroke severity, disability,

and recovery outcomes, especially for LAA strokes

(Smith et al., 2020; Brown et al., 2019) [9]. The results

highlight the urgent need for personalized stroke

rehabilitation programs for diabetic patients, early risk

stratification, and sustained glycemic control (Johnson

& Lee, 2021 [14]; Gonzalez et al., 2022) [12]. Clinical

practice and healthcare policy should prioritize the

integration of diabetes management into stroke care,

while future research should continue to explore

innovative treatment modalities to address the unique

challenges faced by diabetic stroke patients

(Rodriguez et al., 2018 [18]; Wu et al., 2021) [21].

Research on biomarkers of neuroplasticity, such as

BDNF and neurofilament light chain (NfL) levels, could

offer insight into the potential for recovery in diabetic

stroke patients (Lee et al., 2021; Singh et al., 2021) [19].

Additional

randomized

controlled

trials

on

personalized rehabilitation approaches for diabetic

stroke survivors would further strengthen the

evidence base for clinical practice guidelines (Patel et

al., 2020 [17]; Thompson et al., 2019)[20].

4.1 The bar chart. Impact of Type II Diabetes Mellitus (T2DM) on Stroke Severity and

Recovery Outcomes

CONCLUSION

T2DM significantly aggravates the severity and long-

term disability outcomes in patients with ischemic

stroke, especially of the LAA subtype. The coexistence

of both conditions involves a complex interplay of

metabolic, vascular, and neurological factors that

negatively impact stroke prognosis. Diabetic patients

experience more severe initial strokes, slower recovery

trajectories, and higher levels of residual disability

compared to nondiabetic patients. Most of these poor

outcomes are largely related to the increased

atherosclerosis, impaired cerebral autoregulation, and

chronic hyperglycemia, each contributing to impaired

neuroplasticity and recovery potential of the brain.

In the light of the challenges experienced, there is a

great need to formulate and apply definite

rehabilitation programs aimed exclusively at diabetic

stroke patients. Early intervention is quite useful in

attempting to reduce the negative impact of diabetes

on stroke recovery. Individualized rehabilitation

strategies involving intensive physical training,

cognitive training, and blood sugar management have

been found to potentially improve motor and cognitive

recovery as well as functionality. Moreover,

integration of diabetes management into stroke

rehabilitation programs, including the monitoring of

blood glucose and optimization of medication, was

promoting lifestyle modification. This work may

decrease

long-term

disabilities

and

reduce

dependence on carers and generally improve life

quality among diabetic survivors following stroke.

The healthcare provider should highlight the

importance of specialized rehabilitation for this very

vulnerable group of patients. The early diagnosis of

diabetic

stroke

patients

allows

healthcare

professionals to start timely, specific interventions that

may involve intensive rehabilitation therapies, regular

monitoring of glucose levels, and the management of

cardiovascular risks. Neurologists, endocrinologists,

physiotherapists, and occupational therapists form the

multidisciplinary team effort in management. Indeed,

individualized treatment approaches based on

particular needs in diabetic stroke patients will ensure

better functional outcomes and reduce the socio-

economic burden associated with chronic disability.

Although the relationship between diabetes and

stroke outcomes is better understood, much more

needs to be researched in the development and testing

of specific, effective diabetes stroke rehabilitation

programs. Clinical trials should be directed at

determining

optimal

rehabilitation

strategies,

examining the role of emerging technologies, and

determining the long-term benefits of early

intervention. This will help such research to provide

valuable insights into how rehabilitation programs can

be tailored according to the unique challenges faced by

diabetic stroke patients. By prioritizing diabetes-

specific rehabilitation, healthcare systems can enhance

the recovery process, reduce long-term disability, and

improve the overall well-being of patients with

ischemic stroke and T2DM.
