It has been long known that affective disorders as a result of organic brain diseases are not uncommon. Neurological disorders seem to be significant as risk factors for newly diagnosed mania in the elderly. It has been theorized that lesions in the right cerebral hemisphere and limbic structures may produce symptoms suggestive of mania. Even though specific areas of involvement had not been determined, this case discussed below clearly reports a right sided lesion. One of the reasons why not much is known yet about this clinical entity is the rarity of this occurrence. In fact, in one large scale study, only 2 patients out of 700 were identified with mania.
