An ischemic stroke is caused by the deposition of fat in the brain blood vessels. This leads to narrowing of blood vessels and a reduction in blood supply.
A hemorrhagic stroke happens when there is a rupture in a blood vessel due to causes like high BP, road traffic accident, aneurysms, etc.
A transient ischemic attack (TIA) is a mini-stroke that is caused by short-term reduction in brain blood supply. Those who experience TIA are at greater risk of a stroke.
Risk factors include:
- Age – the risk increases significantly over the age of 55
- Men are more at risk than women
- Increased bad cholesterol level
- Unhealthy diet
- Excessive alcohol consumption
- Illegal drug consumption
- Absence of physical activity
- Cardio vascular conditions
- Family history of stroke
