Psychological aspects of multiple sclerosis and its treatment: toward a biopsychosocial perspective.

Multiple sclerosis (MS) is a chronic, progressive neurological disease that produces demyelination of the CNS nerve fibers. With onset most often in young adulthood, the disease produces a variety of neurological symptoms and follows an unpredictable course characterized by exacerbations and remissions. This article reviews the literature on psychological aspects of MS including early psychoanalytic studies and more current psychosocial research. Literature on the relationship between stress and symptoms, and the extent of cognitive impairment experienced is reviewed. A view of psychosocial adjustment to MS based upon an adaptive coping model, and a psychological treatment approach suited to the special needs of individuals with MS are discussed. Finally, a biopsychosocial research model is recommended due to the complex, interactive nature of MS and unique research difficulties it presents.
