Stroke

Stroke is a disorder affecting the heart, arteries, veins or circulation. Some conditions develop gradually, while rhythm problems, stroke, heart attack or vessel rupture can become emergencies within minutes. It is grouped in the Cardiovascular and Heart Diseases section of this library. A diagnosis should not be made from a name or symptom list alone: a clinician considers onset, duration, severity, medical history, examination and appropriate tests. The expected course differs between people, and similar symptoms can arise from unrelated conditions.

Possible features of Stroke may include chest pressure, breathlessness, palpitations, fainting, unusual fatigue, leg swelling, calf pain, dizziness or reduced exercise tolerance. Stroke may cause sudden facial droop, arm weakness, speech difficulty, vision loss or severe imbalance. Not every person develops every feature, and symptom intensity does not always reflect disease severity. Keep a record of when symptoms started, their pattern, possible triggers, medicines and relevant family history. Call emergency services for chest pressure lasting more than a few minutes, sudden neurological symptoms, collapse, severe breathlessness, a new cold painful limb or a very rapid or slow pulse with faintness.

The underlying explanation for Stroke must be assessed individually. In this group, important mechanisms can include the mechanism depends on the condition and may involve atherosclerosis, high blood pressure, structural abnormalities, inflammation, blood clots, electrical conduction problems or inherited disease. Smoking, diabetes, high cholesterol, inactivity and age often modify risk. Risk factors increase probability but do not prove that a person has the condition. Diagnosis may require blood tests, imaging, functional testing, examination by a specialist or tissue sampling, depending on the suspected disorder.

Treatment for Stroke should be based on a confirmed diagnosis and current clinical guidance. Typical management principles include urgent stabilisation when necessary, accurate testing and long-term risk reduction. Care may include blood-pressure or cholesterol treatment, antiplatelet or anticoagulant therapy, rhythm control, procedures, surgery, rehabilitation, exercise, nutrition changes and smoking cessation. The balance of benefit and risk varies with age, pregnancy, other illnesses and current medicines. Do not stop prescribed treatment or substitute complementary products without discussing it with the treating clinician. Follow-up is important to measure response, identify adverse effects and revise the plan. Call emergency services for chest pressure lasting more than a few minutes, sudden neurological symptoms, collapse, severe breathlessness, a new cold painful limb or a very rapid or slow pulse with faintness.
