Continuing Education Activity

Anterior circulation ischemic stroke, most commonly involving the middle cerebral artery (MCA), accounts for a substantial proportion of ischemic cerebrovascular events and represents a major cause of morbidity and mortality. The MCA, a key branch of the internal carotid artery, supplies extensive cortical and subcortical regions, so occlusions are highly symptomatic, with deficits such as hemiparesis, aphasia, neglect, and visual field loss. This activity reviews MCA vascular anatomy, stroke pathophysiology, risk factor identification, and common etiologies, including cardioembolism and atherosclerosis. Participants will also gain an understanding of rapid clinical recognition using standardized tools such as the NIHSS, interpretation of neuroimaging, and timely decision-making for intravenous thrombolysis and mechanical thrombectomy within established treatment windows.  This activity for healthcare professionals is designed to enhance learners' competence in identifying MCA strokes, evaluating acute stroke, addressing risk factors, applying evidence-based, time-sensitive interventions, and implementing an appropriate interprofessional approach when managing this condition, thereby improving patient outcomes.

Objectives:

• Identify clinical features of middle cerebral artery strokes to improve the rapid recognition of acute ischemic events.
• Apply the NIH Stroke Scale accurately in the stratification of stroke severity to guide immediate management decisions.
• Implement evidence-based acute stroke protocols to reduce delays in reperfusion therapy.
• Collaborate with interprofessional team members to ensure coordinated care from emergency presentation through acute treatment in patients affected by middle cerebral artery stroke.

Introduction

Anterior circulation strokes account for 70% of all ischemic strokes that emanate from the carotid arteries into the anterior cerebral arteries (ACA) and middle cerebral arteries.[1] Phylogenetically, the middle cerebral artery (MCA) is the youngest, comprised of a branch from the anterior cerebral artery (ACA) and a branch from the lenticulostriate system (see Image. Anatomy of Brain Vascular Territories). 

The middle cerebral artery is the third right-angle bend of the terminal internal carotid artery (ICA), and is the most common artery involved in acute stroke. The bends of the ICA at the carotid canal (the petrous segment), the carotid siphon, and the proximal dural ring create turbulent flow that disrupts the natural Brownian motion of blood, making the MCA more susceptible to occlusions. The MCA traditionally consists of 4 medium-sized branches: M1, M2, M3, and M4, respectively known as the horizontal, insular, opercular, and cortical segments, which collectively give rise to 10 smaller branches (ie, lateral lenticulostriate, anterior temporal, orbitofrontal, prefrontal, precentral, central, postcentral, parietal, angular, middle temporal arteries).

The prefrontal, precentral, and central branches constitute the superior division, whereas the angular and temporal branches constitute the inferior division (see Image. Divisions of the MCA). These arterioles provide blood supply to a large area of the intracranial hemisphere that includes the frontal, temporal, and parietal lobes, as well as deeper structures of the basal ganglia, internal capsule, and thalamus (see Images. Left Middle Cerebral Artery Territory Infarction and Right Middle Cerebral Artery Stroke). 

Less than 4% of the population possesses an accessory middle cerebral artery, a variant of the middle cerebral artery without a true bifurcation (making the M1 nonexistent), which typically supplies the orbitofrontal location. It can arise from 3 locations: the ICA, the A1 segment of the ACA, which runs parallel to the course of the MCA, or the more distal A2 segment of the ACA.[2][3] Duplication of the MCA occurs in less than 3% of people. 

Mixed pathology (artery-artery embolism and in situ thrombosis) contributes to occlusion of the proximal M1 branch, whereas artery-artery embolism seems to be more common in distal branches.[4] The vast supply of MCA gives rise to a multitude of presenting symptoms, depending on the affected branches and structures.[5] Most screening tools for stroke, eg, the Los Angeles Motor Scale (LAMS), the Cincinnati Prehospital Stroke Scale (CPSS), NIHSS, and FAST, as well as the original mechanical thrombectomy trials (eg, DAWN, DEFUSE), were designed to detect proximal large-vessel MCA strokes.[6][7]

Etiology

Multiple risk factors for stroke, not specific to the MCA, are classified into modifiable and nonmodifiable categories, with substantial overlap between hemorrhagic and ischemic stroke etiologies. Nonmodifiable risk factors include age, sex, race, and genetics. Stroke risk increases with age, with higher incidence in men at younger ages, while mortality risk remains higher in women, African Americans, Hispanics, and Native Americans compared with the white population.

Modifiable risk factors include hypertension, smoking, obesity, alcohol consumption, and diet, all contributing to both ischemic and hemorrhagic stroke. Additional factors, eg, hyperlipidemia, physical inactivity, diabetes, and cardiac conditions including cardiomyopathy, heart failure, and atrial fibrillation, increase risk primarily for ischemic stroke rather than hemorrhagic stroke.

Hemorrhagic stroke most commonly results from hypertension, particularly in developing countries where limited screening and diagnosis obscure disease burden. Less frequently, hemorrhagic stroke results from angiopathies, which cerebral angiography can diagnose.

Ischemic stroke subdivides into atherosclerotic, cardioembolic, lacunar, and cryptogenic etiologies, with additional less common causes including vasculitis, arterial dissections, fibromuscular dysplasia, and genetic disorders. Atherosclerotic disease leads to cholesterol plaque formation, resulting in severe stenosis or thrombosis, which obstructs blood flow and causes cerebral ischemia. Cardioembolic stroke occurs with atrial fibrillation or, in younger individuals, patent foramen ovale, particularly in the setting of deep vein thrombosis. In both scenarios, emboli travel from the heart through the left ventricle into the aorta and lodge in the ICA or its branches, most commonly the MCA. Lacunar infarcts involve small penetrating vessels, eg, the lenticulostriate arteries, which are more susceptible to the effects of hypertension and diabetes through lipohyalinosis rather than thrombotic occlusion.[8]

Epidemiology

Stroke is the fifth leading cause of death in the United States and the second leading cause of death worldwide. The overall prevalence of stroke in the United States is 2.6% in adults older than 20. Approximately 85% of these are ischemic strokes, and over half of all ischemic strokes occur in the MCA territory.[9] The risk of stroke is higher in men than women when young and middle-aged, but overall, women have a higher risk of stroke than men over the course of a lifetime, with the risk for women being 20% to 21% versus 14% to 17% in men. 

The risk of stroke is also higher in Blacks and Hispanics than in Whites. The incidence of stroke in young adults has increased up to 40% worldwide over the past decades.[10] In young Chinese adults, large-artery atherosclerosis and small vessel disease (SVD) were the most common causes of acute ischemic stroke.[11] Occlusion in the middle cerebral artery is the most prevalent cause in this group.[12] Of note, stroke occurrence and mortality have overall decreased in the United States and other high-income countries over time, but no change in frequency has been observed in middle or low-income countries, even though mortality due to stroke has increased in middle and low-income countries. This is likely related to advances in secondary stroke prevention in higher-income countries.[13]

History and Physical

Clinical Assessment

When patients present with neurological symptoms within 24 hours, they are managed as a "Stroke Alert" or a "Code Stroke". The most important component to obtain in the history of these patients is their last known normal, or simply put, when they were last seen at baseline. This determines whether to apply acute treatment strategies and interventions. If the last known normal is within 4.5 hours of presentation, intravenous tissue plasminogen activator (alteplase, TPA) or tenecteplase (TNK) can be offered; if symptoms occur within 24 hours of assessment, mechanical intervention is entertained.

Other important components of the history include the severity of symptoms, a fluctuating or stuttering presentation, and improvement or worsening of deficits. Contraindications to TPA or TNK also need to be queried before administration. This includes any history of intracranial hemorrhage, ischemic stroke within the past 3 months, any recent invasive surgical procedures, neurosurgical or spinal surgeries, internal bleeding, use of anticoagulant medications, trauma, or myocardial infarction. Other components of history that are useful to know are the patient's comorbidities, eg, diabetes, hypertension, and hyperlipidemia.[14]

The most important part of the physical exam is to perform the standardized National Institutes of Health Stroke Scale (NIHSS). The score ranges from 0 to 42. The 15 items are graded on a 3- or 4-point ordinal scale, with 0 indicating no impairment. This scale is particularly useful for identifying and localizing strokes involving the anterior circulation, particularly the middle cerebral artery. The components include sensation, strength, and coordination in all 4 extremities; production and comprehension of speech, including naming and repetition; visual fields; orientation to self and time; and symmetry and sensation of the face. Stroke severity may be stratified based on NIHSS as follows:

• Mild: 1 to 5
• Mild to moderately severe: 5 to 14
• Severe: 15 to 24
• Very severe: >25

An NIHSS score of 0 does not exclude a stroke, but the risks and benefits of treatment should be weighed. Large MCA strokes are usually the easiest to recognize of all strokes, as they tend to present with major deficits such as unilateral flaccidity, forced gaze deviation, visual field cuts, and, if in the dominant hemisphere, speech deficits. In the nondominant hemisphere, loss of prosody to speech and sensory-visual neglect can be detected. An unresponsive patient makes it extremely difficult to assess a stroke in the acute setting, but a lack of withdrawal to noxious stimuli or threats can be a useful clue. When performing the exam, chronic residual deficits from previous strokes or congenital anomalies are important to document. Hypertension and hypotension can also be associated with neurological symptoms.

Distribution-Specific Manifestations

Right MCA distribution strokes may present with anosognosia (unaware of their condition), apraxia, prosody of speech, sensory neglect, and omission of the left half of the "Precarious Painter" picture or sentence reading. Specific syndromes, however, may occur based on the involvement of individual left MCA branches.

The artery of the precentral (pre-Rolandic) sulcus supplies the pars opercularis and pars triangularis of the inferior frontal gyrus, otherwise known as Brodmann areas 44 and 45, respectively, where the Broca area resides. Stroke lesions within this structure produce Broca aphasia, a nonfluent, expressive, or motor-type aphasia, presenting with paucity of speech and inability to repeat, but with preserved comprehension. Please see StatPearls' companion resource, "Aphasia," for further information.

In the inferior division, the angular artery supplies the angular and supramarginal gyri of the temporo-parietal lobe, the posterior part of the superior temporal gyrus, and the superior part of the lateral surface of the occipital lobe. Gerstmann syndrome, also known as Angular Gyrus syndrome, is characterized by a tetrad of symptoms: agraphia (inability to write), acalculia (inability to calculate), finger agnosia (inability to name fingers or body parts), and left-right disorientation. The lesion is invariably in the dominant left angular gyrus (temporal-parietal association cortex), which is involved in visual processing and spatial cognition. 

The middle temporal branches supply the middle aspect of the superior and middle temporal gyri, as well as the primary auditory cortex and Wernicke’s area, a crucial area for receptive or sensory speech apparatus. Impairment in this area produces Wernicke aphasia, a fluent speech littered with neologisms (new word formation) and paraphasic errors, manifesting as poor comprehension and repetition. Please see StatPearls' companion resource, "Wernicke Aphasia," for further information.

The watershed (border zone) regions of the MCA and anterior cerebral artery (ACA), or the MCA and posterior cerebral artery (PCA), produce distinct types of transcortical motor (TcMA) or transcortical sensory (TcSA) aphasia. In the motor type, the lesion affects the anterior superior frontal lobe of the language-dominant hemisphere, whereas in the sensory type, the inferior left temporal lobe is affected. The speech impairment in these patients resembles nonfluent Broca and fluent Wernicke aphasia, respectively, except for the ability to repeat. Please see StatPearls' companion resources, "Anterior Cerebral Artery Stroke," and "Posterior Cerebral Artery Stroke," for further information.

Evaluation

Imaging Studies

The 2 preferred modalities for radiologic imaging in the setting of acute stroke are computed tomography (CT) or magnetic resonance imaging (MRI) (see Image. Right Middle Cerebral Artery Stroke).[15] Regardless of the route taken, obtaining non-contrast imaging and vascular imaging is essential. The CT without contrast will assess for subacute to chronic strokes, any hemorrhage, and hypodense signs that may indicate a large acute stroke. The MRI, particularly diffusion-weighted imaging (DWI), will demonstrate the same findings, as well as acute stroke within minutes to hours.

The next step is either a CT or MR angiogram of the head and neck with perfusion, imaging from the aorta up to the brain. The purpose of the angiogram is to assess areas of stenosis or occlusions that may explain the symptoms. A perfusion scan determines the extent of tissue that has already been damaged versus the extent that is at risk of damage, the core versus the penumbra. This determines whether or not the patient is a candidate for mechanical thrombectomy. Extracranial views of the carotid arteries and the aortic arch assess other embolic etiologies of stroke. If the patient gets a CT and CT angiogram, they will eventually need an MRI as well.[16]

Additional Diagnostic Studies

An electrocardiogram is obtained to look for cardiac changes, which can be detected in 10% to 30% of acute strokes (T-wave inversions, ST elevation, QT prolongation).[17][18] Several important laboratory studies should be performed. One is a coagulation panel, particularly the international normalized ratio (INR), in patients on warfarin. In many centers, an INR of less than 1.7 is considered safe for fibrinolysis administration. Complete blood counts and basic metabolic panels should also be sent. A point-of-care blood glucose test should be obtained during the initial patient evaluation to assess whether this may be contributing to the patient's symptoms. Hypoglycemia can mimic stroke and can be life-threatening if not recognized and treated promptly. Upon admission, other laboratory studies that should be evaluated in patients with stroke include glycosylated hemoglobin levels and a lipid panel for secondary stroke prevention. Additionally, cardiac enzymes should be sent to assess for cardiac abnormalities.[14]

After a stroke has been identified, a full workup and a transthoracic echocardiogram, as well as telemetry monitoring, should be performed to determine whether an intracardiac thrombus or cardiac abnormality is the underlying cause of the patient's stroke. Some of these abnormalities that increase the risk of stroke include atrial fibrillation, a patent foramen ovale, or akinesis or hypokinesis of the cardiac walls. Assessment for a patent foramen ovale is typically indicated in young patients with recurrent strokes of unknown etiology. If a cardioembolic source is likely and these studies are normal, the patient will likely undergo a transesophageal echocardiogram or cardiac MRI to improve visualization of the left ventricle and the left atrial appendage. If the workup proves negative, long-term cardiac monitoring could be considered based on imaging studies to seek cardiac arrhythmia.[19]

Treatment / Management

Acute Interventions

In the acute setting, the interventions for an MCA stroke are intravenous fibrinolysis with tPA or TNK and thrombectomy, if the patient qualifies. For IV thrombolysis, the last known normal must be within 4.5 hours of thrombolytic administration in most hospital settings. However, mismatches on either CT perfusion or DWI/FLAIR scans may extend the window to 6 or 9 hours.[20][21] For thrombectomy, the last known normal has to be within 24 hours of intervention.[6] Outside of this window, no abortive therapy is recommended, and further treatment is geared toward symptom management and secondary stroke prevention.[14] Symptoms that may need to be managed in the acute setting vary with stroke severity. (Please refer to the Complications section for more information.)

Secondary Stroke Prevention

Secondary stroke prevention is aimed at modifiable risk factors that include diabetes, hypertension, hyperlipidemia, and smoking. Glycosylated hemoglobin measures the presence and severity of diabetes. In a stroke patient, the goal is less than 6.5%. This needs to be managed with appropriate diabetic medications, dietary modification, and close monitoring of blood glucose, as well as frequent checks of glycosylated hemoglobin levels approximately every 3 months.

Blood pressure is the single most important modifiable risk factor. In the first 24 hours after the last known period of being well, a period of permissive hypertension is allowed to prevent further ischemic injury to at-risk tissue in the setting of low cerebral perfusion pressure. If the patient does not receive intravenous thrombolysis, the goal is to maintain blood pressure below 220/120 mm Hg. Blood pressure must be under 185/110 before administering IV thrombolysis and 180/105 mm Hg postdelivery for the ensuing 24 hours to decrease the risk of hemorrhagic transformation (see Image. Hemorrhagic Transformation Within the Left Middle Cerebral Artery Territory Infarction).[22] After the first 24 hours, a daily decrease in BP by 15% until normotension is desirable.

The goal for lowering LDL-cholesterol in a patient who has had a stroke is less than 70 mg/dL using high-intensity statin therapy, preferably atorvastatin 40 to 80 mg daily or rosuvastatin 20 mg daily. Age does not preclude high-intensity statin treatment. If a stroke occurred while a patient was on a maximum dose of atorvastatin, a secondary agent, eg, a PCSK9 inhibitor, fenofibrate, or gemfibrozil could be considered as an outpatient. LDL-c needs to be monitored closely every few months to ensure an appropriate response. An additional modifiable risk factor is smoking. Clinicians should emphasize the importance of smoking cessation to a patient who is an active smoker and has had a stroke.[15]

Anticoagulant Therapy

Assessing the need for antiplatelet or anticoagulant treatment varies with the presentation, previous medication, and stroke etiology. If thrombolysis is not administered, it is recommended to initiate dual antiplatelet therapy (DAPT) with aspirin 324 to 650 mg and clopidogrel 300 to 600 mg, depending on the emergency department stroke protocol, within the first 48 hours of symptom onset.[23][24] The subsequent day, DAPT therapy continues with aspirin 81 mg and clopidogrel 75 mg daily for 3 weeks to 3 months. Thereafter, the patient can be continued on either aspirin or clopidogrel monotherapy indefinitely. If the NIHSS score is greater than 4, the recommendation is to load with aspirin. If they were already on aspirin 81 mg daily, switching to clopidogrel 75 mg daily would be warranted.[25] Some institutions may perform point-of-care P2Y12 analysis or CYP2C19 loss-of-function allele testing before clopidogrel administration, and after several weeks of treatment, to ensure platelet inhibition with clopidogrel.[26]

If an intracardiac thrombus or atrial fibrillation is discovered, or a recent history of deep venous thrombosis or pulmonary embolism is present, anticoagulation will be the mainstay of treatment. Studies have indicated that no significant difference in stroke recurrence exists in the setting of holding anticoagulation versus resuming within 24 hours (48 hours if the patient receives IV TPA). However, some studies have indicated a slightly increased risk for hemorrhagic transformation if resumed 48 hours to 7 days. Typically, due to this difference in the risk of hemorrhagic transformation, holding anticoagulation in the immediate period following acute ischemic stroke is recommended.[27][28]

Differential Diagnosis

The differential diagnosis in patients presenting with stroke-like symptoms remains broad due to a large number of stroke mimics. Acute stroke must be promptly excluded in the emergent setting because management is highly time-sensitive. After exclusion of stroke, additional etiologies require systematic evaluation. As previously described, MCA stroke typically presents with unilateral weakness or numbness, facial droop, and speech deficits ranging from mild dysarthria and mild aphasia to global aphasia.

Several dangerous central nervous system processes may mimic stroke, including subdural hematoma (SDH), intracranial hemorrhage (ICH), and intracranial masses. These conditions may produce stroke-like deficits through local mass effect or involvement of brain regions supplied by the MCA. Rapid identification remains essential because these conditions may require urgent neurosurgical intervention. Diagnosis typically relies on emergent CT or MRI obtained during initial stroke evaluation.

Additionally, seizure activity, particularly status epilepticus, may also mimic stroke through gaze deviation, motor deficits, and global aphasia secondary to impaired consciousness. Demyelinating disorders, including multiple sclerosis, may present with focal neurologic deficits such as vision loss, weakness, or sensory changes affecting a single extremity. MRI with and without contrast, combined with detailed history and careful symptom onset characterization, supports differentiation from acute ischemic stroke. Furthermore, toxic, infectious, and metabolic etiologies also require consideration. Sepsis, uremia, hypo- and hyperglycemia, hyponatremia, and hyperkalemia may produce encephalopathy with aphasia, dysarthria, or apparent motor deficits that resemble stroke. These presentations often lack clear focal localization, necessitating broader laboratory evaluation beyond initial stroke workup.

Complex migraines may closely resemble stroke, particularly when visual disturbances, unilateral weakness or numbness, or speech impairment occur. A concurrent headache and prior history of similar episodes support this diagnosis, though advanced imaging and careful history remain important. Psychiatric conditions, including conversion disorder and panic attacks, may present with functional weakness or sensory deficits. These diagnoses remain lower in priority during acute evaluation because other mimics require urgent exclusion, given the potential for severe morbidity or mortality if missed.[29]

Prognosis

The prognosis of middle cerebral artery strokes depends on several factors. The most essential factors in determining prognosis are the size of the stroke, whether the patient received thrombolytic therapy and thrombectomy, and access to rehabilitation following the stroke. Explaining the prognosis after a stroke to the patients and their families can be challenging, particularly in the acute setting. Reaching a new baseline level of function can take from weeks to a year. Patients who suffer smaller cortical strokes typically recover rapidly within a few weeks and then begin to level out over a few months. However, for larger strokes, giving a prognosis in even the first 3 months can be challenging because the process of recovery varies so drastically between individuals. Physical therapy is as important for older patients as for younger patients in improving function.[30]

In the case of severe MCA strokes, in which patients often battle cerebral edema and alteration of consciousness, mortality is frequently dependent upon whether life-saving measures are taken. Many patients qualify for tracheostomy and percutaneous gastrostomy tube placement, which increases the length of hospital stay and the risk of infection. In these patients, the prognosis is grim at best, the likelihood of recovery to baseline function is very low, and survival rates decline.[31]

Complications

Several complications can occur following an MCA stroke. Most stroke patients will develop some complication at some point during their recovery. Approximately 85% of stroke patients experience at least 1 complication during their hospital stay, and most of the remaining individuals develop 1 or more complications within 6 weeks following their stroke. The most common complications to occur in stroke patients while they are still hospitalized include infections, particularly pneumonia or urinary tract infections; falls; and pain. Less common complications include pressure sores, seizures, recurrent stroke, thromboembolism, and psychological complications, particularly depression. Following discharge and the ensuing 30 months, the most common complications include infections, falls, and pain, but depression and anxiety also become prevalent. Concern for seizures and recurrent stroke persisted, and hospital readmission joined the list, while thromboembolism was only seen in one case.[32]

Mobility is affected, particularly in the setting of decreased sensation and strength, making falls more likely. Complications such as dysphagia can lead to aspiration, while decreased mobility can contribute to atelectasis, and both can promote the development of pneumonia. This decreased mobility is a large contributing factor to pressure sores and pain. Interprofessional teams are crucial to the recovery and improvement of stroke patients' quality of life.[33]

Patients who suffer severe strokes tend to suffer from potentially fatal complications. These include cerebral edema, aphagia, and apnea. When cerebral edema occurs, which typically peaks around days 3 to 5 following an acute stroke, edema may increase intracranial pressure on the ventricles and cause a midline shift. Without a compensatory mechanism, this can quickly progress to herniation and death. Ventilatory assistance to protect the airways takes precedence and necessitates urgent discussions with family members and caregivers regarding comfort care and the prolongation of care.[31]

Deterrence and Patient Education

The primary education that is given to patients regarding strokes is risk factor modification for primary and secondary stroke prevention and the warning signals for stroke, at which time they should call 911 and go to the nearest stroke center.

Secondary stroke prevention is implemented by addressing modifiable stroke risk factors, which include hypertension, hyperlipidemia, diabetes, diet, obesity, and smoking. Smoking cessation counseling is an important component of education. Patients are typically started on aspirin if they have not been on it previously. Their cholesterol and glycosylated hemoglobin levels are closely monitored every few months, and if patients have hyperlipidemia or diabetes, these conditions are addressed with the appropriate medications. Close collaboration with the internists and the primary clinician will be crucial. Patients are also advised to closely monitor their blood pressure with an at-home blood pressure cuff, and antihypertensive medications are adjusted accordingly.[15]

As for the signs of an alarm, the acronym FAST has been used for years, but has been replaced in some areas by BEFAST, an acronym for balance, eyes, face, arms, speech, and time. This can be elaborated to give patients a clearer picture of when to return to the emergency department. Balance indicates falling in one direction or dizziness; eyes include sudden unilateral loss of vision or sudden onset double vision; face indicates facial drooping; arms stand for arm weakness or loss of sensation; speech can have multiple meanings including slurring, word-finding difficulty, or difficulty getting words out; and time indicates that "time is brain", prompting urgent transfer to the nearest emergency department.[34]

Enhancing Healthcare Team Outcomes

Anterior circulation stroke, most commonly involving the MCA, accounts for most ischemic strokes and produces significant neurologic morbidity due to its extensive cortical and subcortical vascular territory. MCA occlusion arises from atherosclerotic disease, cardioembolism, or mixed mechanisms and presents with hemiparesis, aphasia, neglect, visual field deficits, and gaze deviation depending on hemispheric involvement. Clinical evaluation relies on rapid neurologic assessment using the NIHSS, identification of last known well, and exclusion of hemorrhage with noncontrast neuroimaging followed by vascular imaging and perfusion studies. Management is highly time-sensitive, with intravenous thrombolysis indicated within 4.5 hours and mechanical thrombectomy considered up to 24 hours in selected patients.

Interprofessional collaboration is essential for optimizing outcomes and safety. Physicians and advanced practitioners lead diagnosis, imaging interpretation, and reperfusion decisions, while emergency nurses ensure rapid stroke activation, monitoring, and medication administration. Pharmacists support anticoagulant and thrombolytic safety, dosing, and interaction checks. Primary care clinicians coordinate risk factor control and secondary prevention. Allied health professionals facilitate rehabilitation, swallowing assessment, and functional recovery. Therapists are necessary to assess and recommend needs on discharge, such as inpatient rehabilitation and home care. The interprofessional team and their daily or biweekly rounds are important for appropriate patient care and planning.[15][35] Coordinated communication, shared decision-making, and standardized stroke pathways reduce delays, prevent complications, and improve long-term patient-centered outcomes.
