The brain is the most complex organ in the human body -- and the least understood. Disorders of the brain or central nervous system (CNS) can be broadly divided into two camps: neuropsychiatric and neurodegenerative. Neuropsychiatric maladies cover depression, schizophrenia, bipolar disorder, and myriad anxiety disorders, while neurodegenerative diseases include Lou Gehrig's, Alzheimer's, Parkinson's, and Huntington's diseases. Strokes, brain tumors, head traumas, migraines, and spinal cord injuries also fall within the CNS realm.
