Neuropsychiatric symptoms (i.e. depression, anxiety, apathy, agitation) are present in nearly all dementia patients, are distressing to caregivers, and can disrupt networks of social support. Little is known about age-related changes in the affective processes that underlie psychological functioning, both in healthy aging and dementia. Emily will study this in marmoset monkeys, who have a short lifespan and naturally develop dementia-like neuropathology. Emily will use this travel award to develop a collaboration with Dr. Eliza Bliss-Moreau, who is an affective neuroscientist with expertise in nonhuman primates. Emily’s project will develop methods to study changes in affective responding, via autonomic nervous system activity, in marmoset monkeys across the lifespan.
