What is StrokeA Stroke is a sudden medical condition that occurs when the blood supply to the brain is interrupted or reduced, depriving brain cells of oxygen and nutrients. This can lead to brain damage, loss of function, or paralysis, depending on the area affected. Strokes are broadly classified into ischemic stroke, caused by a blood clot, and hemorrhagic stroke, caused by bleeding in the brain. Recognizing Stroke symptoms early, such as weakness on one side, difficulty speaking, or vision problems, is critical for timely treatment and better recovery outcomes.
What are the Types of Stroke
| Type of Stroke | Definition / Meaning | Causes | Symptoms | Treatment / Management |
| Ischemic Stroke | A Stroke caused by a blockage in blood vessels supplying the brain. | Blood clots, atherosclerosis, embolism, heart disease | Sudden weakness or numbness (usually one side), slurred speech, vision problems, confusion, dizziness | Thrombolytic therapy, Stroke medication, clot removal, physiotherapy, regenerative cells therapy (in select cases) |
| Hemorrhagic Stroke | A Stroke caused by bleeding in or around the brain. | High blood pressure, aneurysm rupture, head injury, blood vessel malformations | Severe headache, nausea, vomiting, loss of consciousness, seizures, sudden weakness | Controlling bleeding, Stroke surgery, blood pressure management, rehabilitation, supportive therapy |
| Transient Ischemic Attack (TIA / Mini Stroke) | Temporary blockage of blood flow to the brain causing brief stroke-like symptoms. | Small clots, narrowed arteries, heart issues | Sudden weakness, speech difficulty, vision changes, numbness lasting a few minutes to hours | Monitoring, Stroke medication, lifestyle modification, risk factor management |
| Paralytic Stroke | Stroke resulting in partial or complete paralysis. | Brain damage due to ischemic or hemorrhagic stroke | Loss of movement or muscle control on one side, facial droop, speech difficulty | Rehabilitation, physiotherapy, occupational therapy, speech therapy, regenerative therapy in some cases |

What are the Causes of Stroke
| Cause Category | Specific Causes | Type of Stroke Often Associated | Description / Mechanism |
| Cardiovascular Issues | Atrial fibrillation, heart attack, heart valve disease, cardiac thrombus | Ischemic Stroke, Embolic Stroke, Heart Stroke | Abnormal heart rhythm or clots from the heart travel to the brain, blocking blood flow. |
| High Blood Pressure (Hypertension) | Chronic hypertension | Hemorrhagic Stroke, Ischemic Stroke | Weakens blood vessel walls in the brain, increasing risk of rupture or blockage. |
| Atherosclerosis | Plaque buildup in arteries | Ischemic Stroke, Thrombotic Stroke | Narrowing of arteries reduces blood flow, leading to ischemia in the brain. |
| Diabetes | Type 1 and Type 2 diabetes | Ischemic Stroke, Lacunar Stroke | High blood sugar damages blood vessels, increasing risk of clot formation. |
| Lifestyle Factors | Smoking, excessive alcohol, obesity, sedentary lifestyle | Ischemic Stroke, Hemorrhagic Stroke | Contributes to vascular disease, high blood pressure, and clot formation. |
| Blood Disorders / Coagulation Problems | Sickle cell disease, clotting disorders | Ischemic Stroke, Embolic Stroke | Abnormal clotting increases the chance of blocked arteries in the brain. |
| Vascular Abnormalities | Aneurysms, arteriovenous malformations (AVM), vessel malformations | Hemorrhagic Stroke | Weak or malformed vessels can rupture, causing bleeding in the brain. |
| Genetic / Family History | Family history of Stroke or cardiovascular disease | All types | Genetic predisposition to hypertension, clotting disorders, or vessel abnormalities. |
| Infections / Inflammation | Vasculitis, infections affecting blood vessels | Ischemic Stroke | Inflammation or infection can narrow or block cerebral arteries. |
| Hormonal / Gender Factors | Pregnancy, birth control pills, menopause | Ischemic Stroke, Hemorrhagic Stroke | Hormonal changes may increase clotting risk or affect blood pressure. |
| Trauma / Injury | Head injuries, neck injuries | Hemorrhagic Stroke, Brain Stroke | Physical trauma can rupture blood vessels or cause clot formation. |
| Heat / Sun Stroke | Severe heat exposure | Heat Stroke, Cerebral Stroke | Extreme heat can lead to dehydration, blood thickening, or brain swelling, occasionally causing stroke-like symptoms. |
What are the Symptoms of Stroke

How Stroke Is Diagnosed at Plexus
Accurate and timely Stroke diagnosis is crucial for effective treatment and recovery. Plexus employs a multidisciplinary approach combining clinical assessment, advanced imaging, and laboratory tests to identify the type, location, and severity of a stroke. Each step is tailored to ensure patients receive rapid intervention, whether it is an ischemic stroke, hemorrhagic stroke, or brain stroke.
1. Comprehensive Clinical Assessment
The first step in diagnosing Stroke at Plexus involves a thorough neurological examination. Physicians evaluate the patient for Stroke symptoms such as sudden weakness, numbness on one side, facial droop, speech difficulties, vision changes, balance problems, and cognitive impairment. Specialists also consider patient history, including risk factors like hypertension, diabetes, heart disease, and prior episodes of TIA (mini stroke). Early recognition of subtle signs , sometimes referred to as mild Stroke symptoms , allows for rapid intervention, improving outcomes.
2. Imaging Tests
Once initial signs suggest a stroke, Plexus uses advanced imaging techniques to confirm the diagnosis and differentiate between ischemic Stroke and hemorrhagic stroke. Common imaging modalities include:
- CT Scan (Computed Tomography): Quickly identifies bleeding, brain swelling, or structural abnormalities. It is the first-line imaging test for suspected stroke.
- MRI (Magnetic Resonance Imaging): Provides detailed images of brain tissue, detecting smaller ischemic strokes or early changes not visible on a CT scan.
- MR Angiography / CT Angiography: Assesses the blood vessels of the brain and neck to locate blockages, clots, or aneurysms that may have caused the stroke.
3. Laboratory Tests
Blood tests are performed to evaluate conditions that may contribute to a stroke, including clotting disorders, high cholesterol, diabetes, and infection. Tests like a complete blood count (CBC), lipid profile, and coagulation studies help identify underlying causes of Stroke (Stroke causes) and guide treatment decisions, such as Stroke medication or anticoagulant therapy.
4. Cardiac Evaluation
Since many strokes, especially embolic or heart stroke, originate from the heart, Plexus includes cardiac assessments as part of diagnosis. Tests may include ECG (Electrocardiogram), Echocardiography, or Holter monitoring to detect atrial fibrillation, heart valve disease, or cardiac thrombus that can lead to brain stroke.
5. Functional and Cognitive Assessment
After confirming the stroke, Plexus conducts a detailed evaluation of the patient’s motor, speech, and cognitive functions. This helps in identifying deficits caused by the Stroke and planning personalized Stroke rehabilitation physiotherapy, occupational therapy, and speech therapy. Early assessment of functional impairment ensures that interventions such as Stroke supportive therapy or regenerative cells therapy can be integrated into the recovery plan effectively.
