🗒 Notes

Definition: Stroke is a clinical syndrome characterized by a rapid onset of a focal neurological deficit that lasts more than 24 hours or leads to death. A Transient Ischemic Attack (TIA), on the other hand, resolves within 24 hours.

Types of Stroke: There are two primary types of stroke: Ischemic Stroke (85%) which is caused by a blockage, and Hemorrhagic Stroke (15%) which is caused by bleeding in the brain due to a ruptured vessel or aneurysm.

Risk Factors: These include non-modifiable factors such as age, gender, and family history, as well as modifiable factors like hypertension, diabetes, smoking, dyslipidemia, and heart disease.

Clinical Presentation: The symptoms of stroke vary depending on the location and size of the affected brain area. Common symptoms include sudden weakness, facial droop, speech difficulties, and loss of coordination.

Management: Immediate action is crucial. The type of stroke is determined through urgent diagnostic tests like CT or MRI. Treatments vary, with thrombolytic therapy for ischemic strokes and surgical intervention for hemorrhagic strokes.

📝 Summary

Stroke is a severe medical condition that requires urgent attention. Recognizing the signs early and differentiating between types (ischemic or hemorrhagic) is essential for providing the correct treatment and minimizing long-term disability or death. Prevention involves managing risk factors, especially hypertension and lifestyle changes.
