Abstract

Over the past years, increasing attention has been paid to the frequency of neuropsychiatric symptoms (NPS) in dementia, also known as the behavioral and psychological symptoms of dementia. This study’s main goal was to determine the prevalence of Mild Behavioral Impairment (MBI) and its subdomains in patients with Mild Cognitive Impairment (MCI) in Iran. Participants included 96 patients with MCI who attended the memory clinic between July and December 2020. Global cognitive function was evaluated using the Persian version of the Montreal Cognitive Assessment (MoCA). To assess MBI, the Persian version of the MBI checklist (MBI-C) was completed by the patient or a close caregiver. The mean age of patients was 71.4 ± 9.3 years, and 56 patients (58.3%) were female. Regarding the cutoff point of 6.5, 48 patients (50%) had MBI. In both groups of MBI and non-MBI, 28 (58%) were female. There was no significant difference in MBI subdomains scores and total MBI scores between the two genders. In addition, we found no significant difference in total MBI in patients with different risk factors. There was no significant difference in MoCA score between MBI and non-MBI patients (24.1 ± 3.9 versus 23.7 ± 4.0) (p = 0.59). NPS are highly prevalent in MCI patients, with the most common ones being impulse dyscontrol, emotional dysregulation, and decreased motivation. Psychotic symptoms and social inappropriateness are rare. New-onset psychiatric symptoms and behavioral changes in older adults, even in a mild form (MBI), should increase the suspicion of subsequent cognitive impairment.
