ABSTRACT
In this chapter, the term cognitive neuropsychiatry is used loosely to group together the literature on deja vu in a range of psychiatric conditions and also the influence of pharmacology on deja vu. The emphasis here is not on delusional familiarity, but rather on genuine deja vu where the experient is aware of the erroneous nature of the experience. The chapter focuses on deja vu in anxiety, the possibility that there exists a particular form of chronic deja vu without an organic basis, psychogenic deja vu, and the relationship between dissociative experiences and déjà vu. It discusses the literature on deja vu in schizophrenia. Schizophrenia is a mental disorder featuring a breakdown in the relation between thought, emotion and behaviour. Its key characteristics are delusion and hallucination which lead to inappropriate actions and feelings. It is also known to have a complex profile of cognitive impairment and preservation.
