Antidepressants for agitation and psychosis in dementia.Seitz DP, Adunuri N, Gill SS, Gruneir A, Herrmann N, Rochon P Department of Psychiatry, Queen's University, 752 King Street West, Kingston, Ontario, Canada, K7L 4X3. Published 17 February 2011 in Cochrane Database Syst Rev, 2: CD008191. Articles on Psychosis published 1 February 2011: Olfactory hallucinations in schizophrenia and schizoaffective disorder: a phenomenological survey. Psychiatry Res, 185(3): 321-7. Olfactory hallucinations (OHs), so it has been argued, are prognostic of a poorer outcome, are unpleasant, and cannot be well explained within current theoretical accounts of hallucinations. We examined these and related issues by conducting structured interviews with 51 participants who experienced OHs and who were previously diagnosed with schizophrenia or schizoaffective disorder. We found no relationship between disease severity measures and type or frequency of OHs. As with prior research, ... [Abstract] [Full-text] Articles on Psychosis published 31 January 2011: Coping strategies and their relationship to psychopathologies in people at ultra high-risk for psychosis and with schizophrenia. J Nerv Ment Dis, 199(2): 106-10. This study's aim was to investigate coping strategies and their relationship to symptoms in people at ultra high risk (UHR) for psychosis compared with recent-onset schizophrenia (SPR) and healthy controls. Thirty-three UHR participants, 22 SPR patients, and 33 healthy controls completed the Ways of Coping Questionnaire and other clinical measures. People at UHR for psychosis showed significantly more reliance on tension-reduction and less reliance on problem-focused coping than healthy ... [Abstract] [Full-text] Articles on Psychosis published 5 January 2011: Delusional ideation and self-esteem in individuals with psychotic disorders. J Nerv Ment Dis, 199(1): 58-61. The present study is an examination of the association of self-esteem with various themes of delusional thinking for individuals with psychotic disorders. Individuals with psychotic disorders (N = 30) completed a measure of delusional ideation and a measure of severity of delusions and also a measure of self-esteem. Results indicated individuals with higher levels of delusional thinking in the domains of persecution, thought disturbances, catastrophic ideation/thought broadcast, and negative ... [Abstract] [Full-text] Associations of anhedonia and cognition in persons with schizophrenia spectrum disorders, their siblings, and controls. J Nerv Ment Dis, 199(1): 30-7. The aim of the current study was to investigate the levels of social and physical anhedonia, as measured with the Chapman Scales for social and physical anhedonia in groups of patients with schizophrenia spectrum psychosis (n = 91), their unaffected siblings (n = 105), and control subjects drawn from a general population (n = 67). The second aim was to explore the effect of physical and social anhedonia on neuropsychological variables. Subjects with schizophrenia spectrum disorder had ... [Abstract] [Full-text] Articles on Psychosis published 20 December 2010: Catechol-O-methyltransferase Val158Met polymorphism and negative symptoms after acute antipsychotic treatment in first-episode non-affective psychosis. Psychiatry Res, 185(1): 286-9. Genetic factors play an important role in the understanding of clinical response to antipsychotic treatments. We aimed to assess the effect of the catechol-O-methyltransferase (COMT) genotype in the short-term (6 weeks) clinical response of 161 first-episode psychosis patients. COMT genotype was not related to clinical response at 6 weeks. Val homozygote patients showed higher negative symptoms than Met homozygote patients. The COMT Val158 genotype seems to be related to the severity of ... [Abstract] [Full-text] Twelve-month follow-up of family communication and psychopathology in children and adolescents with a first psychotic episode (CAFEPS study). Psychiatry Res, 185(1): 72-7. We analyzed the potential influence of family relationships and history of psychiatric disorders on the presentation and course of early psychotic disorders. We recruited 110 subjects aged 9-17 years with a first psychotic episode and 98 matched healthy controls, and followed them for 1 year. Data were collected through clinical interviews and the Parent-Adolescent Communication Inventory. A family history of psychosis-related disorders was more common in patients' families, with a five-fold ...
