The first part of the book begins with an overview of depression, its incidence and manifestations and neurobiological origins; how it''s diagnosed; and its relevance to neurology, in particular to suicidality. The second part looks at depression in distinct conditions, in particular: migraine, stroke, epilepsy, Parkinson''s Disease, Huntington''s Disease, dementia, and traumatic brain injury. This useful guide takes a practical approach, with "tips and tricks" boxes, case studies, points of interest boxes, and take-home summaries.
