1, 13 Visual hallucinations frequently consist of formed images, predominantly of people, animals, and objects. ![]() ![]() Visual hallucinations are reported to occur in 60%-76% of pathologically confirmed DLB patients 10-12 they are among the most common neuropsychiatric symptoms and have been identified as one of the core features in the clinical diagnostic criteria of DLB. 6-9 Therefore, the management of neuropsychiatric symptoms is a significant issue for maintaining the quality of life of patients with DLB and their caregivers. 2-5 It has been suggested that caring for patients with DLB leads to a heavier caregiver burden than caring for those with Alzheimer’s disease because of the involvement of neuropsychiatric symptoms such as delusions and hallucinations. 1 A range of neuropsychiatric symptoms such as hallucinations, delusions, and sleep disturbances occur more frequently in DLB patients than in Alzheimer’s disease patients from the early stages of the disease. The core clinical features of DLB include neuropsychiatric symptoms, the motor symptoms of parkinsonism, and cognitive impairments characterized by deficits of memory, attention, executive function, and visual perception. * Corresponding author: Mamoru Hashimoto, MD, PhD, Department of Neuropsychiatry, Faculty of Life Sciences, Kumamoto University, 1-1-1 Honjo, Chuo-ku, Kumamoto 860-8556, Japan ( with Lewy bodies (DLB) is the second most common type of degenerative dementia among the elderly after Alzheimer’s disease. © Copyright 2018 Physicians Postgraduate Press, Inc.ĪDepartment of Neuropsychiatry, Graduate School of Medical Science, Kumamoto University, Kumamoto, JapanīDepartment of Geriatric Psychiatry, Mitsugumachi Clinic, Kumamoto, JapanĬDepartment of Neuropsychiatry, Faculty of Life Sciences, Kumamoto University, Kumamoto, JapanĭDepartment of Psychiatry, Heisei Hospital, Yatsushiro, Kumamoto, JapanĮDepartment of Psychiatry, Osaka University Graduate School of Medicine, Suita, Osaka, Japan Clinical features of auditory hallucinations in patients with dementia with Lewy bodies: a soundtrack of visual hallucinations. To cite: Tsunoda N, Hashimoto M, Ishikawa T, et al. Auditory hallucinations in patients with DLB are more likely to occur in women and those with impaired hearing, depression, delusions, or visual hallucinations. 038).Ĭonclusions: Auditory hallucinations are common neuropsychiatric symptoms in DLB and usually appear as a background soundtrack accompanying visual hallucinations. The analysis also revealed independent correlations between the presence of auditory hallucinations and visual hallucinations ( P <. Multiple logistic regression showed that the presence of auditory hallucinations was significantly associated with female sex ( P =. Auditory hallucinations consisted mostly of human voices, and 90% of patients described them as like hearing a soundtrack of the scene. The majority of patients (90.9%) with auditory hallucinations also had visual hallucinations. Results: Of the 124 patients, 44 (35.5%) had auditory hallucinations and 75 (60.5%) had visual hallucinations. We performed multiple logistic regression analysis to identify significant independent predictors of auditory hallucinations. ![]() ![]() We reviewed all available clinical records of patients with auditory hallucinations to assess their clinical features. We used the Neuropsychiatric Inventory to assess the presence of auditory hallucinations, visual hallucinations, and other neuropsychiatric symptoms. Methods: We recruited 124 consecutive patients with probable DLB (diagnosis based on the DLB International Workshop 2005 criteria study period: June 2007-January 2015) from the dementia referral center of Kumamoto University Hospital. We investigated the clinical features of auditory hallucinations and the possible mechanisms by which they arise in patients with DLB. Objective: Auditory hallucinations are an important symptom for diagnosing dementia with Lewy bodies (DLB), yet they have received less attention than visual hallucinations.
