Chapter 22.Psychotic Disorders
Sections
Excerpt
Psychosis (i.e., hallucinations and/or delusions occurring in an otherwise clear sensorium) has been recognized as a potentially devastating consequence of traumatic brain injury (TBI) since at least the early nineteenth century. While it has long been reported that individuals with TBI experience psychosis at higher rates than the general population (Achté et al. 1969; Chen et al. 2011; Davison and Bagley 1969; Harrison et al. 2006), the nature of this association remains uncertain. Considerable scientific disagreement exists regarding the nature of psychotic symptoms that develop in the chronic phase of TBI recovery and how such symptoms are or are not clinically and pathophysiologically distinct from those of primary psychotic disorders such as schizophrenia.
