Can you tell me about transient ishcemic attack (mini stroke)?

TIA: Implies temporary decrease in blood flow to a localized area of brain which results in symptoms such as loss of vision, numbness, unilateral weakness, incoordination, etc. May be due to blood vessel narrowing, an embolic fragment of a clot, primary cardiac arrhythmia, etc. Key here is reversibility, otherwise would be stroke. If it does occur, cause should be uncovered and treated to prevent cva.

Usually associated: With carotid artery disease in the neck- see pcp for wk up!
