Anterior cingulate activation in antipsychotic-naïve first-episode schizophrenia

ACTA PSYCHIATRICA SCANDINAVICA, Issue 2 2007
M. Yücel
Objective:, Anterior cingulate (ACC) hypo -activity is commonly observed in chronically ill schizophrenia patients. However, it is unclear whether this is secondary to persistent illness and/or medication. Method:, We examined eight antipsychotic-naïve first-episode patients and matched healthy controls undergoing PET scanning while performing the Stroop task. Results:, Group-averaged and single-subject analyses showed ACC activation in both controls and patients, albeit in different sub-regions (paracingulate and cingulate respectively). A direct comparison revealed relative under-activity of the left paracingulate cortex in patients. Conclusion:, These findings suggest that the more pervasive hypo -activation observed in chronic patients may be secondary to persistent illness and/or medication. [source]


Reducing the duration of untreated first-episode psychosis , effects on baseline social functioning and quality of life

ACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2005
I. Melle
Objective:, Long duration of untreated psychosis (DUP) is associated with poorer outcome. The TIPS study demonstrated that DUP can be reduced through early detection (ED). As quality of life (QoL) is associated with DUP it is expected that reduction of DUP leads to better QoL. Method:, Consecutive first-episode patients with a DSM-IV diagnosis of non-organic, non-affective psychosis were included, 281 patients gave informed consent and 263 completed a full evaluation of QoL. Results:, There were no differences in subjective QoL between ED and No-ED groups attributable to reduction in DUP. There were significant bivariate differences in frequency of family and social contacts in favor of the ED group, but multivariate analyses indicated that these differences were based on differences in sample characteristics. Conclusion:, Deterioration in QoL may precede overt symptom formation. Focus on functional loss in ED educational campaigns may identify risk subjects earlier in the course of the disorder.

One-year outcome of an early intervention in psychosis service: a naturalistic evaluation

EARLY INTERVENTION IN PSYCHIATRY, Issue 3 2007
Swaran P. Singh
Abstract Aim: We conducted a 1-year prospective evaluation of an early intervention in psychosis service (Early Treatment and Home-based Outreach Service (ETHOS)) during its first 3 years of operation in South-west London, UK. Methods: All patients referred to ETHOS underwent structured assessments at baseline and at 1-year follow-up. In addition, hospitalization rates of ETHOS patients (intervention group) were compared with a non-randomized parallel cohort (comparison group) of first-episode patients treated by community mental health teams. Results: The Early Treatment and Home-based Outreach Servicepatients experienced significant improvements in symptomatic and functional outcomes, especially vocational recovery. The service received only a quarter of eligible patients from referring teams. ETHOS patients did not differ from the comparison group in number of admissions, inpatient days or detention rates. Although number of referrals increased over time, there was no evidence that patients were being referred earlier. Conclusions: There is now robust evidence for the effectiveness of specialist early intervention services. However, such services must be adequate resourced, including an early detection team and provision of their own inpatient unit. [source]


Efficacy of amisulpride in treating primary negative symptoms in first-episode psychosis: a pilot study

HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 8 2006
Brendan P. Murphy
Abstract Objective Negative symptoms are debilitating and associated with poor role functioning and reduced quality of life. There is a paucity of research on antipsychotic efficacy against the primary negative symptoms, particularly in first-episode psychosis (FEP). We undertook a prospective, open-label pilot trial to investigate the use of amisulpride in the treatment of young people with FEP characterised by primary negative symptoms. Method Twelve male and two female first-episode patients with primary negative symptoms (aged 16,26) were commenced on low-dose amisulpride (mean 250,mg/day) and followed-up over a 6-month period. Primary outcome measures were the Scale for the Assessment of Negative Symptoms (SANS), the Quality of Life Survey (QLS) and their respective subscales. Results For the 12 completers there was a statistically significant improvement in SANS summary score (p,=,0.036), Affective Flattening subscale global score (p,=,0.046), QLS total score (p,=,0.021), QLS subscales of Instrumental Role (p,=,0.018) and Intra-psychic Foundations (p,=,0.009) from baseline to week 24. Conclusions Amisulpride appears to be associated with less severe negative symptoms and improved quality of life. Generalisabilty of the findings is limited by the small sample size and open-label design of our study, however the positive findings suggest that further controlled trials are warranted.

The neuropsychology and neuroanatomy of bipolar affective disorder: a critical review

BIPOLAR DISORDERS, Issue 3 2001
Carrie E Bearden
Objectives: To present a comprehensive review of the existing neuropsychological and neuroimaging literature on bipolar affective disorder. This review critically evaluates two common conceptions regarding the neuropsychology of bipolar disorder: 1) that, in contrast to schizophrenia, bipolar affective disorder is not associated with general cognitive impairment independent of illness episodes, and 2) relative right hemisphere (RH) dysfunction is implicated in bipolar illness patients, supported by reports of relatively greater impairment in visuospatial functioning, lateralization abnormalities, and mania secondary to RH lesions. Methods: The major computerized databases (Medline and PSYCInfo) were consulted in order to conduct a comprehensive, integrated review of the literature on the neuropsychology and neuroanatomy of bipolar disorder. Articles meeting specified criteria were included in this review. Results: In a critical evaluation of the above notions, this paper determines that: 1) while there is little evidence for selective RH dysfunction, significant cognitive impairment may be present in bipolar illness, particularly in a subgroup of chronic, elderly or multiple-episode patients, suggesting a possible toxic disease process, and 2) the underlying functional correlate of these cognitive deficits may be white matter lesions (,signal hyperintensities') in the frontal lobes and basal ganglia, regions critical for executive function, attention, speeded information processing, learning and memory, and affect regulation. While this hypothesized neural correlate of cognitive impairment in bipolar disorder is speculative, preliminary functional neuroimaging evidence supports the notion of frontal and subcortical hypometabolism in bipolar illness. Conclusions: The etiology of the structural brain abnormalities commonly seen in bipolar illness, and their corresponding functional deficits, remains unknown. It is possible that neurodevelopmental anomalies may play a role, and it remains to be determined whether there is also some pathophysiological progression that occurs with repeated illness episodes. More research is needed on first-episode patients, relatives of bipolar probands, and within prospective longitudinal paradigms in order to isolate disease-specific impairments and genetic markers of neurocognitive function in bipolar disorder.
