Neuropsychiatric Symptoms and Antipsychotic Therapy in the Elderly Patients with Dementia

Abstract

The objective of the study was to investigate syndromal-nosological specificities of neuropsychiatric symptoms (NPS) and the frequency of use of antipsychotics in patients with various types of dementias, institutionalized to geriatric units of mental hospitals.Patients and methods: a total of 106 in-patients of three psychogeriatric units were examined. The median age of patients is 75 years [69; 80].The diagnostic distribution of patients at the time of the examination was as follows: in 33 subjects (31.1%) Alzheimer’s disease (AD) was diagnosed, in 25 (23.6%) - mixed dementia (MD), in 32 (30.2%) - vascular dementia (VD) and in 16 (15.1%) patients had dementia of complex origin (DCO).Results: a high incidence (54.7%) of NPS was found in patients with dementia of various origins. The greatest number of patients with behavioral and psychotic symptoms was found in AD and MD. The proportion of dementia patients with such disorders in each of these types of dementia is about 70%, while in CGD and VD, the proportion of patients with NPS is noticeably smaller (30% and 40%, respectively). For the treatment of NPS, antipsychotics were most often prescribed, but their use caused adverse events (AEs) in 1/3 of cases. Patients with VD are most susceptible to the development of AE, and AD patients are the least susceptible.Conclusion: the study showed that NPS are one of the important components of dementia, regardless of the nosology and stage of the disease. The treatment of NPS in dementia is particularly challenging because, although the symptoms cause significant distress, there are currently no effective alternative therapies. The risk of AE can be minimized by carefully considering the indications for prescribing antipsychotics and their short-term use, regular monitoring of the patient’s condition, and educating caregivers.
