Neural Basis of Anxiety in Dementia With Lewy Bodies
Objective
The association between core clinical features and anxiety and the neural basis of anxiety in patients with dementia with Lewy bodies (DLB) are unknown. Therefore, this study examined the core clinical features associated with anxiety in DLB and identified the brain regions associated with anxiety using statistical imaging analysis.
Methods
This study was conducted using a part of the data from “The Japan multicenter study: Behavioral and psychological symptoms Integrated Research in Dementia-Retrospective Neuroimaging part”. Overall, 40 patients with probable DLB whose clinical dementia rating score was either 0.5 or 1 were included in this study. Anxiety was evaluated using the Neuropsychiatric Inventory (NPI). The incidence of each of the 4 core features was compared between patients with and without anxiety, and the brain regions associated with anxiety were examined using single-photon emission computed tomography data.
Results
Patients with DLB with anxiety had a significantly higher percentage of fluctuating cognition than those without anxiety. The NPI anxiety score was significantly negatively correlated with regional cerebral blood flow in the right supramarginal gyrus in patients with DLB.
Conclusion
Anxiety in DLB is associated with fluctuating cognition. It is also likely that the brain regions associated with anxiety in DLB are potentially influenced by the neurofunctional characteristics of DLB, in which the parietal lobes are more likely to be impaired.
期刊介绍：
The rapidly increasing world population of aged people has led to a growing need to focus attention on the problems of mental disorder in late life. The aim of the Journal is to communicate the results of original research in the causes, treatment and care of all forms of mental disorder which affect the elderly. The Journal is of interest to psychiatrists, psychologists, social scientists, nurses and others engaged in therapeutic professions, together with general neurobiological researchers.
The Journal provides an international perspective on the important issue of geriatric psychiatry, and contributions are published from countries throughout the world. Topics covered include epidemiology of mental disorders in old age, clinical aetiological research, post-mortem pathological and neurochemical studies, treatment trials and evaluation of geriatric psychiatry services.
