Introduction[edit | edit source]
A transient ischaemic attack (TIA) is an acute episode of temporary neurologic dysfunction that typically has the following characteristics[1]
- lasts less than an hour (often less than 30 minutes)
- results from focal cerebral, spinal cord, or retinal ischaemia
- is not associated with acute tissue infarction
Mechanism of Injury / Pathological Process
[edit | edit source]
TIAs are characterized by a temporary reduction or cessation of cerebral blood flow in a specific neurovascular distribution, which occurs as a result of partial or total occlusion - typically, from an acute thromboembolic event or from stenosis of a small penetrating vessel.
Epidemiology[edit | edit source]
Internationally, the probability of a first TIA is around 0.42 per 1000 population in developed countries. TIAs occur in about 150,000 patients per year in the United Kingdom.
Clinical Presentation[edit | edit source]
Clinical manifestations will vary, depending on the vessel involved and the cerebral territory it supplies
