[The transient ischemic attack, between diagnosis and treatment].

The transient ischemic attack (TIA) in cerebral circulation in 161 patients is studied. The causes and favouring factors are analysed, arterial hypertension and dyslipidemias representing 70% of the factors that might be incriminated in the physiopathology of TIAs. The paraclinical and therapeutic results demonstrate that in over 30% of the cases the etiology could be explained by "the multiple defect theory", the importance of transcranial Doppler in the diagnosis and prognosis of TIA, especially in the young patients, being underlined.
