Objective. Comorbidities between psychiatric diseases and consumption of traditional substances of abuse (alcohol, cannabis, opioids, and cocaine) are common. Nevertheless, there is no data regarding the use of novel psychoactive substances (NPS) in the psychiatric population. The purpose of this multicentre survey is to investigate the consumption of a wide variety of psychoactive substances in a young psychiatric sample and in a paired sample of healthy subjects. Methods. A questionnaire has been administered, in different Italian cities, to 206 psychiatric patients aged 18 to 26 years and to a sample of 2615 healthy subjects matched for sex, gender, and living status. Results. Alcohol consumption was more frequent in the healthy young population compared to age-matched subjects suffering from mental illness (79.5% versus 70.7%; P < 0.003). Conversely, cocaine and NPS use was significantly more common in the psychiatric population (cocaine 8.7% versus 4.6%; P = 0.002) (NPS 9.8% versus 3%; P < 0.001). Conclusions. The use of novel psychoactive substances in a young psychiatric population appears to be a frequent phenomenon, probably still underestimated. Therefore, careful and constant monitoring and accurate evaluations of possible clinical effects related to their use are necessary.

ObjectiveIndividuals suffering from dementia are affected by a progressive and significant global deterioration and, consequently, might require longer assistance in the advanced stage of the illness. The illness is a great burden on the person who takes care of a patient, namely, the caregiver. This study aims to analyze the presence and relationship of specific sociodemographic variables, subjective burden, and depressive symptoms among caregivers of patients with dementia.MethodsThe participants of this study were caregivers at a health care unit for the elderly in southern Italy. An evaluation of the burden of patients with dementia on caregivers was carried out using the Caregiver Burden Inventory (CBI) and depressive symptoms using the Self-Rating Depression Scale (SDS).ResultsA total of 150 caregivers completed the study. In all, 83 (55%) caregivers showed a total CBI score ≥36, of whom 70% showed pathological depression scores in SDS. According to SDS, 28 (19%) caregivers showed a total CBI score from 24 to 36, of whom 32% were depressed. Depression was present in 5% of the caregivers whose CBI score was <24. Hence, an association between burden and depression was evident (χ2=47.446, P<0.001). A multiple linear regression analysis showed that depression (adjusted R2=0.622, F=50.123, P<0.001) was associated with higher physical (β=0.666, P=0.001) and developmental (β=0.712, P<0.001) burdens, lower socioeconomic status (β=−4.282; P=0.002), higher level of urbanicity (β=3.070; P=0.012), and advanced age (β=2.132; P=0.08).ConclusionOur study confirms the presence of depressive symptoms in a large number of caregivers with high burden. Nevertheless, this study demonstrates that depressive symptoms are mainly associated with sociodemographic variables and, to a lesser degree, physical and developmental burdens.

The use of atypical antipsychotic drugs in the elderly has become wider and wider in recent years; in fact, these agents have novel receptor binding profiles, good efficacy with regard to negative symptoms, and reduced extrapyramidal symptoms. However, in recent years, the use of both conventional and atypical antipsychotics has been widely debated for concerns about their safety in elderly patients affected with dementia and the possible risks for stroke and sudden death. A MEDLINE search was made using the words elderly, atypical antipsychotics, use, schizophrenia, psychosis, mood disorders, dementia, behavioral disorders, and adverse events. Some personal studies were also considered. This paper reports the receptor binding profiles and the main mechanism of action of these drugs, together with their main use in psychiatry and the possible adverse events in elderly people.

The use of NPS in a young psychiatric population appears to be frequent, and probably still underestimated. Bipolar disorder shows an association with NPS use. Careful and constant monitoring and an accurate evaluation of possible clinical effects related to NPS use are necessary.
