Blood clots: Typical tia's are associated with progressive closure of a blood vessel by thrombosis locally or by a clot at a distance lodging in a narrow blood vessel and blocking blood flow. The underlying risks include hypertension, heart disease, high blood fats (espec triglycerides), diabetes, and hyperhomocysteinmia) so to prevent a tia, treat underlying risks.
