Description

Nine individual neuropsychiatric symptom domains (agitation or aggression, anxiety, apathy or indifference, delusions, depression or dysphoria, disinhibition, hallucinations, irritability or lability, nighttime behaviors) measured using the Neuropsychiatric Symptom Inventory Questionnaire were tested for association with single-nucleotide polymorphisms (SNPs) with minor allele frequency > 5% in a sample of 12,806 participants with mild cognitive impairment or dementia.

Participants were sampled from Alzheimer’s Disease Research Centers (ADRCs) throughout the United States and were of European genetic ancestry. For each NPS domain, a participant was classified as a “case” if they experienced the symptom in the month preceding any visit, and as a “control” otherwise. Parallel logistic regressions were performed for each NPS domain while controlling for sex (male v. female), batch (categorical with 15 levels), and the first 10 genetic PCs.
