Depressive episodes in patients with multiple sclerosis.

R B Schiffer, E D Caine, K A Bamford

    The American Journal of Psychiatry
    |November 1, 1983
    PubMed
    Summary

    Multiple sclerosis patients with brain involvement showed significantly more major depressive episodes than those with spinal cord and cerebellar issues. This highlights a potential link between lesion location and depression in multiple sclerosis.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Neurology

    Background:

    • Multiple sclerosis (MS) is a chronic demyelinating disease affecting the central nervous system.
    • Depression is a common comorbidity in MS, impacting quality of life.
    • The relationship between lesion location and psychiatric symptoms in MS requires further elucidation.

    Purpose of the Study:

    • To investigate the association between the location of demyelination in multiple sclerosis and the prevalence of major depressive episodes.
    • To compare depressive symptoms and episodes between MS patients with predominantly cerebral involvement versus those with predominantly spinal cord and cerebellar involvement.

    Main Methods:

    • Thirty multiple sclerosis patients were divided into two groups: 15 with cerebral involvement and 15 with spinal cord/cerebellar involvement.

  • Groups were matched for age, illness duration, and Kurtzke disability scores.
  • Assessments included neuropsychological testing, the Beck Depression Inventory, and psychiatric interviews (Schedule for Affective Disorders and Schizophrenia). Normal volunteers served as controls for neuropsychological testing.

    • Main Results:

    • The group with predominantly cerebral multiple sclerosis involvement exhibited significantly more major depressive episodes compared to the spinal cord/cerebellar group.
    • A trend towards more depressive symptoms was observed in the cerebral involvement group, as indicated by Beck Depression Inventory scores.

    Conclusions:

    • Cerebral involvement in multiple sclerosis appears to be associated with a higher incidence of major depressive episodes.
    • These findings suggest that the location of central nervous system lesions in MS may influence the risk and presentation of depression.
