Stroke is a condition when a part of the human brain is deprived of blood (thrombosis or embolism) or a blood vessel bursts and blood puts pressure on the brain. There are two types of Stroke, Ischaemic stroke and Haemorrhagic stroke. One is caused by a blockage, cutting off the blood supply to brain and Haemorrhagic stroke is when there is bleeding in or around the brain.
-
The common symptoms of stroke are face shift or drooping or numbness, arm movement shift, speech slurry, trouble in vision and more. The usual risk factors could be old age or even family history, high blood pressure, high cholesterol, diabetes can also play a role.
-
After the clinical examination, the CT scan of the brain (done in seconds) reveals haemorrhagic or ischemic stroke.
-
If Stroke is haemorrhagic, treatment is surgical and/or conservative. If stroke is ischemic, treatment depends upon the time lag. The earlier a stroke patient is brought to Hospital, the better are his/her chances of recovery. The first 4.5 hours are critical for treatment and are considered as Golden Window. Thrombolysis is also a common treatment in such cases often given within this golden period. This means breaking down and dispersing the clot which is preventing blood from reaching the brain.
