Abstract
Several studies have investigated the frequency of epileptic seizures follo wing ischemic strokes and transient ischemic attacks (TIAs). Little attenti on has been paid to the possibility that seizures may be precipitated by TI As. We examined if seizures can be the only symptom of a TIA and how often this might occur. We performed a retrospective analysis of clinical charts and electroencephalograms of 160 consecutive patients evaluated for a first -ever seizure from January 1997 to December 1999 at Belluno General Hospita l. From January to May 2000, 19 more first-ever seizure patients were evalu ated directly. Four patients (2%) had seizures in the presence of important risk factors for ischemic stroke (atrial fibrillation in two patients, atr ial fibrillation and ventricular mural thrombus in one patient, hemodynamic ally significant left carotid stenosis in one patient). Seizures were not a ccompanied by other neurological deficits or brain lesions on CT or MRI. As risk factors for brain ischemia are frequent in the general population not developing seizures, our results do not prove that the occurrence of seizu res was more than casual in these patients. Yet they indicate that in a sma ll percentage of patients, seizures can occur in a context highly suggestiv e of TIA, with no other focal deficits.
