30 patients aged between 45 and 78 years and who had suffered from transient global amnesia (TGA), were seen at the Department of Neurology, Pordenone Public Hospital, in the period 1978 to 1982. 25 patients had one or more risk factors for cerebrovascular disease, such as hypertension, cardiac abnormalities, diabetes and hyperlipidemia. EEG examination revealed abnormal activity only in 7 patients. Brain Computed Tomography showed cerebral atrophy in 10 and hypodense lesions in 3 patients. 16 patients had been followed up for a mean interval of 20 months. During the follow-up period, 4 patients had recurrent TGA and one had a transient ischemic attack in the vertebrobasilar arterial system. In the follow-up group, 15 patients showed permanent memory impairment. The high incidence of risk factors for cerebrovascular disease seems to confirm that TGA is probably due to transient cerebral ischemia. The high rate of permanent memory impairment, almost always connected with the coexistence of cerebrovascular risk factors, is not in agreement with the postulated good prognosis of TGA.

Transient global amnesia (AGT) is a well-defined syndrome of unknown aetiology. It is generally believed to be of vascular origin. Other theories suggest epilepsy or migraine as the cause. We studied the clinical features and associated risk factors in 24 patients with AGT, comparing them with two control groups with 24 people in each group, paired for age and sex. The first control group contained healthy individuals (CN) and the second patients with transient ischaemic attacks (AIT). Of the patients with AGT, 70% were women and 30% men. Their average age was 60 (range 14-76). The attacks were abrupt in onset in 100%. In 8% there was a recognisable trigger factor (driving, physical exercise, etc). The average duration was 7 hours. On study of the cardiovascular risk factors, it was found that 36% were hypertensive, 24% had cardiopathy, 12% had diabetes mellitus, 8% were smokers, 4% had polycythaemia, 16% had hyperlipidaemia, 4% were alcoholics. There was a history of migraine in 29%. No patient had a past history of epilepsy. Further investigation showed ECG changes in 12%. In 24% there were non-specific changes in the EEG. On cerebral CT scan there were lesions compatible with ischaemia in 12.5% of the patients. Levels of arterial hypertension were significantly higher in the AGT group as compared to the normal control group (Odds ratio 7.86; CI. 1.29-11.38). A past history of migraine was seen to be a risk factor associated with AGT as compared with both groups of controls (AGT/CN Odds ratio 9.47; CI 1.01-444.92; AGT/AIT Odds ratio > 1.72).

The purpose of this article was to explore sex- and race-specific variables and comorbidities associated with transient global amnesia (TGA) using a nationally representative database. Data were obtained from the Nationwide Inpatient Sample using ICD-9 and procedure codes. Descriptive and survey logistic regression analyses were conducted and adjusted for influence of comorbidities, demographic characteristics, and hospitalization-related factors. Patients with migraines were 5.98 times more likely to also have a diagnosis of TGA compared with patients without migraines. Similarly, patients with TGA were more likely to have hypertension, precerebral disease, and hyperlipidemia. The odds of being diagnosed with TGA was lower among African Americans and Hispanics as well as among patients classified as Asian/Other, compared with Caucasians. TGA was associated with lower hospital charges ($14,242 versus $21,319), shorter hospital stays (mean days: 2.49 [SE=0.036] versus 4.72 [SE=0.025]), and routine hospital discharges (91.4% versus 74.5%). Patients with migraines and patients classified as Caucasian had higher odds of being diagnosed with TGA. All minority populations showed a lower rate of diagnosis that fell short of statistical significance.
