Stroke

Blocking blood flow to the brain leads to oxygen deprivation and potential brain cell destruction, causing a stroke. Such an event is a medical emergency needing quick intervention to avoid major consequences or mortality. Two basic forms of strokes are hemorrhagic stroke, brought on by a ruptured blood vessel resulting in brain haemorrhage, and ischaemic stroke, brought on by a blood clot obstructing an artery. A mini-stroke, or transient ischaemic attack (TIA), is a brief blockage acting as a signal for subsequent strokes.
Typical symptoms include confusion, trouble speaking, loss of balance, severe headache, and vision issues; abrupt numbness or weakness in the face, arm, or leg (particularly on one side) is common. Early recognition of these symptoms using the FAST approach—face drooping, arm weakness, speech difficulty, and time to call emergency services—can save lives.
To find the type and origin of the stroke, diagnosis calls for CT scans, MRIs, and blood testing. Treatment relies on the type; hemorrhagic strokes may call for surgery, whereas ischaemic strokes may call for thrombectomy or clot-busting medications. To lower stroke risk, preventive actions include regular exercise, a healthy diet, blood pressure control, and avoidance of smoking or too much alcohol intake.
