| Outline of Final Research Achievements |
Agitation is the most common and difficult to treat among behavioral and psychological symptoms of dementia (BPSD) . The objective of this study was to identify a region where changes in DNA methylation levels are associated with agitation. Using genome-wide DNA methylation analysis data, we determined a signaling pathway in the WNT5A gene promoter region to be associated with agitation. Based on this result, we measured DNA methylation levels in this region for 26 dementia subjects with agitation and 82 dementia subjects without agitation. The WNT5A DNA methylation level in subjects with agitation was significantly lower than in those without agitation. This change was not influenced by age, sex, body mass index, APOE ε4, medication or inflammatory cytokines. This results suggested an association of agitation with changes in WNT5A DNA methylation levels, which could be a potentially useful biomarker of agitation. It may contribute to the elucidation of the mechanism of BPSD.
