We examined by neuropsychological tests 41 patients who had presented attacks of transient global amnesia (TGA; 31 had single and 10 multiple episodes), comparing them with 41 matched normal controls. Patients with single attacks showed only two impaired memory tasks with respect to controls (immediate and long-term verbal memory), while patients with multiple attacks showed more impaired tasks in memory and visuoperceptual ability. These data confirm that TGA is a benign syndrome, but could leave a few subclinical memory deficits probably exacerbated by repeated attacks.

A clinical observation and a neuropsychological study in a patient with amnesic attacks due to epileptic seizures were performed.

The authors studied a 26-year-old healthy subject in whom a large arachnoid cyst of the right middle cranial fossa was revealed by chance. As there were no subjective or objective neurological finding

Thirty-five patients affected with sporadic motor neuron disease (MND) and without clinically evident mental deterioration were systematically investigated by means of neuropsychological tests, quantitative analysis of EEG and brain CT. The MND patients as a group showed a slight but definite and stereotyped cognitive impairment. Temporal slow EEG activity was increased in the whole MND group and posterior background activity was slower in the more cognitively impaired patients. No significant differences were found in CT measurements of brain atrophy between MND and controls.
