The relationship between depression and neurologic illness is complex in several aspects, including pathophysiology, clinical presentation, and response to treatment. Depression may sometimes be the direct result of brain pathology, very much like other neurological manifestations, such as cognitive or motor disturbances. In other cases, a more complex interplay of neurobiological, environmental, and coping mechanisms appears responsible for the development of depressive symptoms (Box 5-1). Neurologic illness may produce signs and symptoms that mimic depression, such as psychomotor retardation, apathy, concentration deficits, and sleep disorders, making the diagnosis of depression in the context of neurologic illness challenging. However, the identification and treatment of depression in these individuals is of fundamental importance, as this tends to improve the prognosis of the neurological disease.
