There are two types of stroke – those caused by blood clots in the brain and those that occur when blood vessels burst. In both cases, the brain is starved of oxygen, damaging or killing cells. Sufferers are often left with difficulty talking, walking and performing other basic tasks. The chance of suffering a stroke is cut by eating healthily, quitting smoking and drinking less alcohol. People at risk of stroke are often treated with aspirin. After a stroke, various drug treatments are available and reIn both types of stroke – those caused by blood clots and those caused by burst blood vessels – blood supply to the brain is interrupted, depriving the cells of oxygen and other nutrients. The cells are then damaged or die. Mini-strokes, or transient ischaemic attacks (TIAs), may be a warning sign of an imminent full-blown stroke. Rehabilitation is commonly used to improve patients’ speech and movement.
Drugs to treat heart conditions and stroke adjust the working of the heart or circulation of the blood. Most are taken orally as tablets or capsules to be swallowed, but they can come in the form of tablets held under the tongue, aerosols or patches. Drugs can also be administered directly into a vein or a muscle.
