title: CT and EEG investigations in 100 patients with multiple sclerosis (MS).
abstract: 100 MS patients were followed up for an average of 5 years. We considered age at onset, duration of the disease, number of attacks, neurological and psychic status, CT and EEG findings and tried correlating the last two with all the previous factors. In remission the most frequent CT abnormality was diffuse atrophy. In acute exacerbations there were 3 possibilities: normality, hypodensity and, much more rarely, hyperdensity with pseudotumoral patterns. A normal CT and short duration of disease were positively correlated with a small number of attacks. There were no positive correlations between CT findings, age at onset and neurological and psychic status. EEG, like CT, may show no changes in a high percentage of cases but there is scant correlation between the two.
