Rev Med Liege 2014, 69(2),64-67Abstract : We report the case of a man aged 62 suffering from a known type I bipolar disorder and referred by his attending psychiatrist because of a state of spatiotemporal disorientation, confusion and prostration evoking significant neurologic impairment. The interest of this case report is in the use of the 18-FDG PET-Scanner, which is increasingly widespread in clinical psychiatry, to support the differential diagnosis between a psycho-organic pathology like dementia or a functional psychiatric pathology like depressive pseudo-dementia (also named melancholic dementia), in which some patterns of dysfunction can now be identified by functional imaging.
