Stroke affects cognitive domains especially memory, attention, orientation and language. Some people may have only a temporary disruption of blood flow to the brain, known as a transient ischemic attack (TIA), that doesn’t cause lasting symptoms.
There are two main causes of stroke: a blocked artery (ischemic stroke) or leaking or bursting of a blood vessel (hemorrhagic stroke). Strokes are broadly classified into hemorrhagic and ischemic strokes. A stroke is a brain attack that is caused either by reducing blood and oxygen flow to the brain or by bleeding. Dementia is a syndrome that causes loss of several distinctive but overlapping intellectual abilities.Īmong the neurological diseases in adult life, stroke ranks first in frequency and importance.
Memory dysfunction and cognitive impairment following stroke occur commonly that affects the quality of life.
