Neuropsychiatric Symptoms in Mild Cognitive Impairment: A Literature Review.

Neuropsychiatric Symptoms in Mild Cognitive Impairment: A Literature Review. Dement Geriatr Cogn Disord. 2020 Apr 14;:1-13 Authors: Martin E, Velayudhan L Abstract BACKGROUND: Neuropsychiatric symptoms (NPS) in dementia have received much attention due to their high prevalence and their significant implications. NPS in mild cognitive impairment (MCI), a clinical concept proposed as an intermediate state between normal aging and dementia, is now gradually gaining in interest. We aimed to conduct a selective review to examine the prevalence rate of NPS in MCI and associations of NPS symptoms with disease progression. SUMMARY: We searched the PubMed database for articles on NPS in MCI and included articles that fulfilled the inclusion criteria. NPS was present in 35-85% of MCI patients. The most common symptoms were depression, irritability, apathy, anxiety, agitation, and sleep problems. Although the associated risk for disease progression of some symptoms, such as apathy and anxiety, was more consistent across studies, evidence was conflicting for symptoms like depression and sleep problems. NPS tend to co-occur, and certain combinations of NPS had a mutual or cumulative effect on disease progression. Late-onset NPS, even in a mild form (mild behavioural impairment) were found to be associated with an increased risk of dementia, even in the absence of cognitive impairment. Key Messages: NPS are highly prevalent in MCI patients...
