Multiple sclerosis (MS) is one of the most frequently seen neurological causes of progressive disability in early to middle adulthood. The disease is variable in its presentation and course, affects roughly 100–300 per 100,000 persons within the United States alone, and is slightly more common among females than males. MS places substantial burdens on patients, families, and caregivers. It negatively affects cognitive abilities and psychiatric functioning, and can add a notably deleterious effect on a patient's quality of life. This chapter reviews the recent literature on the behavioral manifestations of MS. Cognitive domains discussed include executive functioning, processing speed, attention, learning and memory, language functioning, and visual spatial processing. Some attention will also be paid to differential diagnosis and the cognitive effects of treatment. Psychiatric manifestations are also discussed, including symptoms of depression, bipolar disorder, euphoria, pathological laughter and crying, and psychosis, as well as maladaptive personality traits. Finally, the chapter concludes with a discussion of the effects of MS on quality of life including such areas as fatigue, sexual dysfunction, pain, employment, and cognitive functioning.
