Weight gain is a widely reported side effect of clozapine, but no predictive factor has been identified so far. We investigated whether pretreatment values of circulating leptin or its early changes during clozapine administration could predict the long-term weight gain induced by the drug. Body weight and plasma levels of leptin were prospectively measured in 22 patients (13 men and 9 women) with drug-resistant schizophrenia undergoing a long-term treatment with clozapine. At the end of the second week of clozapine administration, circulating leptin increased much more than weight gain, and this increase was inversely correlated to body weight increase observed after 6 and 8 months of treatment. These findings suggest that early changes in leptin secretion may predict long-term weight gain in the course of clozapine administration.

This paper describes a pedigree with Huntington's disease (HD), in which three cases of obsessive-compulsive disorder (OCD) and two cases of pathological gambling (PG) were identified. The mutation analysis of the HD gene was carried out in the examined individuals who were at risk for HD. In fact, OCD and PG only occurred in carriers of the HD expansion. The possible implications of this finding are discussed.

Background: Full functional recovery is defined as a state in which patients are again able to enjoy their usual activities, return to work, and take care of themselves, and it should represent the end goal of treatment in patients with major depressive disorder (MDD). Patients with MDD report many unmet needs, including residual cognitive symptoms, lack of improvement in psychosocial functioning and life satisfaction, even during mood symptom remission. In this paper, we aim to: (a) identify the available assessment tools for evaluating cognitive and psychosocial functioning in patients with MDD; (b) provide an overview of therapeutic options that can improve full functional recovery in MDD also by improving cognitive symptoms.Methods: The relevant databases MEDLINE, ISI Web of Knowledge – Web of Science Index, Cochrane Reviews Library and PsychoINFO were searched for identifying papers on validated tools for the assessment of cognitive and personal functioning in patients with MDD.Results: New assessment tools (such as the THINC-it TOOL, the COBRA, the SCIP-D, and the UPSA-D) have been developed for evaluating the cognitive dysfunction in MDD patients. Adopting these tools in the clinical routine practice is useful to evaluate the improvement in cognitive functioning and, therefore, the achievement of full functioning recovery. The optimal management of patients with MDD include the combination of pharmacological compounds and psychosocial interventions for achieving full functional recovery in patients with MDD.Conclusions: Full functional recovery must be the target of any treatment programme for patients with MDD. In order to achieve this goal, it is necessary to develop personalized treatment and integrate psychosocial and psychopharmacological interventions.
