The following Clinical Topic Tour provides an overview of stroke and was adapted from materials published by the National Institute of Neurological Disorders and Stroke and the Centers for Disease Control and Prevention.
|
|
A stroke is the sudden death of brain cells in a localized area due to inadequate blood flow.

 |
A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack." See also: Arteriovenous malformation (AVM)

|
There are various clinical and pathological subtypes of stroke, and identification of the subtype is necessary for correct management. Investigations Imaging Brain imaging should be performed within the first 48 hours of the onset of stroke (see below), to determine whether the stroke is haemorrhagic or ischaemic and to exclude other causes (e.g. tumour).
