Neuropsychological investigations have demonstrated that cognitive disorders are common (about 60%) in patients with multiple sclerosis.

22 patients and 22 controls participated in the study with a review of literature.

The cognitive dysfunction may be termed a subcortical white matter dementia.

The hallmarks are: forgetfulness, reduced speed of information processing, impaired attention and slowness of thought processes, impaired ability to manipulate acquired knowledge.

Psychiatric disturbance have also high prevalence: emotional or personality changes, depression.

Pathological laughing and crying are classical but not well understood.

This intellectual and emotional changes in multiple sclerosis are studied by adapted psychometric psychiatric examination.

Correlation of magnetic resonance imaging with neuropsychological testing is now demonstrated.

Total lesion score is the best predictor of cognitive deficits, cerebral atrophy and lesions of the corpus collosium also.

Neuropsychological rehabilitation techniques and symptomatic treatments must be applied to patients with multiple sclerosis.
