Psychiatric aspects of dementia

Purpose of Review: The psychiatric aspects of dementia are increasingly recognized as significant contributors to distress, disability, and care burden, and, thus, are of increasing interest to practicing neurologists. This article examines how psychiatric disorders are entwined with dementia and describes the predictive, diagnostic, and therapeutic implications of the psychiatric symptoms of dementia. Recent Findings: Psychiatric disorders, particularly depression and schizophrenia, are associated with higher risk for late-life dementia. Psychiatric phenomena also define phenotypes such as frontotemporal dementia and dementia with Lewy bodies, cause distress, and amplify dementia-related disabilities. Management requires a multidisciplinary team, a problem-solving stance, programs of care, and pharmacologic management. Recent innovations include model programs that provide structured problem-solving interventions and tailored in-home care. Summary: There is new appreciation of the complexity of the relationship between psychiatric disorders and dementia as well as the significance of this relationship for treatment, community services, and research.
