OBJECTIVES It has been argued that attachment theory could enhance our knowledge and understanding of psychotic phenomenology.

METHODS We searched databases Pub Med, PsycINFO, Medline and Web of Science using the keywords. Attachment,...

Folie à deux is a relatively rare mental disorder first described in France in 1877 by Laségue and Falret. However, folie á deux is still a matter of study and debate today as it remains a challenge for psychiatrists. The aim of our work is to report a clinical case of folie á deux, subtype A of Gralnick, between an inducer daughter and an induced mother who lived quite socially isolated and ha...

Schizophrenia and bipolar disorder are often viewed as distinct clinical disorders, however there is substantial overlap in their neuropathologies. While compromised cortical interneurons are implicated in both diseases, few studies have examined the relative contribution of the distinct interneuron populations to each psychotic disorder. We report reductions in somatostatin and vasoactive inte...

BACKGROUND Schizophrenia and bipolar disorder share overlapping symptoms and genetic etiology. Functional brain dysconnectivity is seen in both disorders. METHODS We compared 70 schizophrenia and 64 psychotic bipolar probands, their respective unaffected first-degree relatives (n = 70, and n = 52), and 118 healthy subjects, all group age-, gender-, and ethnicity-matched. We used functional ne...
