, Definition of Stroke
Stroke is not a diagnosis but a clinical
syndrome with numerous causes
The main types of stroke and their relative
occurrence are:
Cerebral infarction (85%)
Intracerebral haemorrhage (10%)
Subarachnoid haemorrhage (5%) BIKHA
, Transient Ischaemic Attack (TIA)
Also defined as an acute focal neurological
deficit resulting from cerebrovascular
disease, but the symptoms and signs
resolve within 24-hours
Most patients recover within 30-min
No fundamental difference between TIA and
stroke except for the duration of the
symptoms
