Abstract:
To estimate the proportions of specific hypometabolic patterns and their association with neuropsychiatric symptoms (NPS) in patients with cognitive impairment (CI). Methods This multicenter study with 1037 consecutive patients was conducted from December 2012 to December 2019. 18 F‐FDG PET and clinical/demographic information, NPS assessments were recorded and analyzed to explore the associations between hypometabolic patterns and clinical features by correlation analysis and multivariable logistic regression models. Results Patients with clinical Alzheimer's disease (AD, 81.6%, 605/741) and dementia with Lewy bodies (67.9%, 19/28) mostly had AD‐pattern hypometabolism, and 76/137 (55.5%) of patients with frontotemporal lobar degeneration showed frontal and anterior temporal pattern (FT‐P) hypometabolism. Besides corticobasal degeneration, patients with behavioral variant frontotemporal dementia (36/58), semantic dementia (7/10), progressive non‐fluent aphasia (6/9), frontotemporal lobar degeneration and amyotrophic lateral sclerosis (3/5), and progressive supranuclear palsy (21/37) also mostly showed FT‐P hypometabolism. The proportion of FT‐P hypometabolism was associated with the presence of hallucinations ( R = 0.171, p = 0.04), anxiety ( R = 0.182, p = 0.03), and appetite and eating abnormalities ( R = 0.200, p = 0.01) in AD. Conclusion Specific hypometabolic patterns in FDG‐PET are associated with NPS and beneficial for the early identification and management of NPS in patients with CI.
