A stroke occurs when the blood supply to the brain is blocked (ischemic stroke) or when a blood vessel in the brain bursts (hemorrhagic stroke). This prevents brain cells from getting oxygen, causing them to become damaged.
Common warning signs include sudden weakness or numbness on one side of the body, difficulty speaking, blurred vision, loss of balance, and a severe headache. Seek emergency medical care immediately if these symptoms appear.
During a stroke, the brain does not receive enough oxygen and nutrients, causing brain cells to become damaged. This can affect movement, speech, memory, vision, and other body functions.
The four main types of stroke are Ischemic Stroke, Hemorrhagic Stroke, Transient Ischemic Attack (TIA or mini-stroke), and Cryptogenic Stroke, where the exact cause cannot be identified.
Stroke treatment depends on its type. It may include clot-busting medications, minimally invasive procedures, surgery, rehabilitation, and lifestyle changes. Early treatment improves recovery and reduces complications.
