P02-10 Abnormal emotional responses to pleasant and unpleasant visual stimuli in first episode schizophrenia: f-MRI investigation

Aims:Affective deficits (flat affect, a diminished expression of emotion, anhedonia, and lowered ability to experience pleasure) are very common in schizophrenia. In emotion feeling, the crucial role of the insula, rather than of the primary somatosensory cortices, strongly suggests that the neural substrate for emotions is not merely sensorial. It is more likely that the activation of the insula representation of the viscero-motor activity is responsible for feeling of disgust. A recent MRI study demonstrated specific left anterior insular volume reduction in chronic schizophrenia patients: sustainable is the suggestion that emotion of disgust or of taste may be related to the experience of pleasure, which probably is compromise in schizophrenics.We investigated fMRI brain activations in first episode schizophrenic subjects with negative symptoms and in healthy subjects elicited by pleasant and unpleasant visual stimuli.Method:Ten first-episode schizophrenic subjects with normal IQ were recruited from the psychiatric service "SMILE" of San Salvatore Hospital and 10 healthy volunteers matched for age and education were scanned during observation of pleasant and unpleasant visual stimuli. Functional images were acquired with a 1.5T MRI scanner. Blood oxygenation level dependent (BOLD) contrast was obtained using EPI T2* weighted images.Results:The most important result of the study was the demonstration that anterior insula was activated by the exposure to disgusting stimula in normal subjects but not in schizophrenic subjects.Conclusion:This failure of the neural systems used to support emotional attribution is consistent with pervasive problems in experiencing emotions by schizophrenics

An observational study in psychiatric acute patients admitted to General Hospital Psychiatric Wards in Italy

OBJECTIVES: this Italian observational study was aimed at collecting data of psychiatric patients with acute episodes entering General Hospital Psychiatric Wards (GHPWs). Information was focused on diagnosis (DSM-IV), reasons of hospitalisation, prescribed treatment, outcome of aggressive episodes, evolution of the acute episode. METHODS: assessments were performed at admission and discharge. Used psychometric scales were the Brief Psychiatric Rating Scale (BPRS), the Modified Overt Aggression Scale (MOAS) and the Nurses' Observation Scale for Inpatient Evaluation (NOSIE-30). RESULTS: 864 adult patients were enrolled in 15 GHPWs: 728 (320 M; mean age 43.6 yrs) completed both admission and discharge visits. A severe psychotic episode with (19.1%) or without (47.7%) aggressive behaviour was the main reason of admission. Schizophrenia (42.8% at admission and 40.1% at discharge) and depression (12.9% at admission and 14.7% at discharge) were the predominant diagnoses. The mean hospital stay was 12 days. The mean (± SD) total score of MOAS at admission, day 7 and discharge was, respectively, 2.53 ± 5.1, 0.38 ± 2.2, and 0.21 ± 1.5. Forty-four (6.0%) patients had episodes of aggressiveness at admission and 8 (1.7%) at day 7. A progressive improvement in each domain/item vs. admission was observed for MOAS and BPRS, while NOSIE-30 did not change from day 4 onwards. The number of patients with al least one psychotic drug taken at admission, in the first 7 days of hospitalisation, and prescribed at discharge, was, respectively: 472 (64.8%), 686 (94.2%) and 676 (92.9%). The respective most frequently psychotic drugs were: BDZs (60.6%, 85.7%, 69.5%), typical anti-psychotics (48.3%, 57.0%, 49.6%), atypical anti-psychotics (35.6%, 41.8%, 39.8%) and antidepressants (40.9%, 48.8%, 43.2%). Rates of patients with one, two or > 2 psychotic drugs taken at admission and day 7, and prescribed at discharge, were, respectively: 24.8%, 8.2% and 13.5% in mono-therapy; 22.0%, 20.6% and 26.6% with two drugs, and 53.2%, 57.8% and 59.0% with > two drugs. Benzodiazepines were the most common drugs both at admission (60.0%) and during hospitalisation (85.7%), and 69.5% were prescribed at discharge. CONCLUSION: patients with psychiatric diseases in acute phase experienced a satisfactory outcome following intensified therapeutic interventions during hospitalisation

Family functioning and personal growth in Italian caregivers living with a family member affected by schizophrenia: Results of an add-on study of the Italian network for research on psychoses

To date, the role of family members in caring for relatives affected by schizophrenia has focused largely on the negative aspects of impact of the illness. The present study aimed to: (1) assess family functioning and burden of care in caregivers living in Northern, Central, and Southern Italy who looked after subjects affected by chronic schizophrenia; (2) evaluate the relationship between aspects of family functioning and burden of care, in particular personal growth (PG) of caregivers; and (3) identify variables capable of affecting PG of caregivers. A total of 136 caregivers (mean length of illness of family member more than 20 years) were recruited from 9 Italian research sites and evaluated in terms of "positive" family functioning-problem-solving, communication skills and personal goals Family Functioning Questionnaire (FFQ), burden of care, and PG Family Problems Questionnaire (FPQ). Caregivers reported an overall good family functioning with a relatively low objective and subjective burden of care. The latter was positively correlated with length of illness, with women showing a higher subjective burden than men. Reduced problem-solving skills and ability of each family member to pursue personal goals were both associated with reduced objective and subjective burden which, conversely, were both increased by inadequate support and scarce positive comments from relatives and friends. Approximately 50% of caregivers stated that "they had learned something positive from the situation," highlighting a statistically higher proportion of caregivers in southern Italy than in northern and central Italy. Caregivers' PG was associated with good family functioning, adequate professional support, and positive comments. PG also seemed to be positively influenced by support from relatives and friends (O.R. 14.306). The numerous challenges and positive aspects associated with caregiving should be duly acknowledged by mental health services and integrated into routine clinical assessment and intervention framework

The Use of Antidepressant Drugs and the Lifetime Prevalence of Major Depressive Disorders in Italy

BACKGROUND: The increased use of antidepressant drugs (ADs) improved the response to the needs of care although some community surveys have shown that subjects without lifetime psychiatric diagnosis (anxiety/depression) used ADs. OBJECTIVES: To evaluate the appropriateness and amount of prescription of psychotropic drugs in people with lifetime diagnosis of Major Depressive Disorder (MDD) by means of community survey with a semi-structured interview as a diagnostic instrument, administered by clinicians. METHODS: STUDY DESIGN: community survey. STUDY POPULATION: samples randomly drawn, after stratification from the adult population of municipal records. Sample size: 4.999 people were drawn in 7 centres of 6 Italian regions. TOOLS: questionnaire on psychotropic drug consumption, prescription, health services utilization; Structured Clinical Interview for DSM-IV modified (ANTAS); Training: interviewers were trained psychologists or medical doctors. RESULTS: 3.398 subjects were interviewed (68% of the recruited sample). The lifetime prevalence of DSM-IV MDD was 4.3% in males and 11.5% in females; antidepressant drugs were taken by 4.7% of subjects, 2.9% male and 5.9% female. 38% of males and 57% of females with lifetime diagnosis of MDD were taking ADs. CONCLUSIONS: Compared with studies using lay interviewers and structured tools the prevalence of the MDD was quite lower; ADs use was higher and tallied well with the data regarding antidepressant sales in Italy; the correspondence between lifetime diagnosis of MDD and ADs use was closer

Deficit of social cognition in subjects with surgically treated frontal lobe lesions and in subjects affected by schizophrenia

The ability of humans to predict and explain other people’s behaviour by attributing independent mental states such as desires and beliefs to them, is considered to be due to our ability to construct a “Theory of Mind”. Recently, several neuroimaging studies have implicated the medial frontal lobes as playing a critical role in a dedicated “mentalizing” or “Theory of Mind” network in the human brain. In this study we compare the performance of patients with right and left medial prefrontal lobe lesions in theory of mind and in social cognition tasks, with the performance of people with schizophrenia. We report a similar social cognitive profile between patients with prefrontal lobe lesions and schizophrenic subjects in terms of understanding of false beliefs, in understanding social situations and in using tactical strategies. These findings are relevant for the functional anatomy of “Theory of Mind”

Sub-threshold depression and antidepressants use in a community sample: searching anxiety and finding bipolar disorder

<p>Abstract</p> <p>Background</p> <p>To determine the use of antidepressants (ADs) in people with sub-threshold depression (SD); the lifetime prevalence of mania and hypomania in SD and the link between ADs use, bipolarity and anxiety disorders in SD.</p> <p>Methods</p> <p>Study design: community survey. Study population: samples randomly drawn, after stratification from the adult population of municipal records. Sample size: 4999 people from seven areas within six Italian regions. Tools: Questionnaire on psychotropic drug consumption, prescription; Structured Clinical Interview NP for DSM-IV modified (ANTAS); Hamilton Depression Rating Scale (HAM-D); Mood Disorder Questionnaire (MDQ); Short Form Health Survey (SF-12). SD definition: HAM-D > 10 without lifetime diagnosis of Depressive Episode (DE).</p> <p>Results</p> <p>SD point prevalence is 5.0%. The lifetime prevalence of mania and hypomania episodes in SD is 7.3%. Benzodiazepines (BDZ) consumption in SD is 24.1%, followed by ADs (19.7%). In SD, positive for MDQ and comorbidity with Panic Disorder (PD) or Generalized Anxiety Disorders (GAD) are associated with ADs use, whereas the association between a positive MDQ and ADs use, without a diagnosis of PD or GAD, is not significant. Only in people with DE the well-being (SF-12) is higher among those using first-line antidepressants compared to those not using any medication. In people with SD no significant differences were found in terms of SF-12 score according to drug use.</p> <p>Conclusions</p> <p>This study suggests caution in prescribing ADs to people with SD. In people with concomitant anxiety disorders and SD, it should be mandatory to perform a well-designed assessment and evaluate the presence of previous manic or hypomanic symptoms prior to prescribing ADs.</p
