Apathy, a profound loss of initiative and motivation, is often seen in older Veterans with memory problems. Apathy leads to serious health problems, increases dependency, and caregiver burden. If untreated, apathy hastens the progression to frank dementia. In a pilot study, the investigators found that apathy, working memory, and function can be restored using magnetic stimulation in some but not all older Veterans. The reason for this variation is unknown. The investigators propose a three-phase study in 125 older Veterans with mild memory problems. Their motivation, memory, and function will be measured periodically. Veterans with apathy that are eligible for treatment will receive either real or sham magnetic stimulation to the front part of their brain over 20 sessions. Genetic testing and biomarkers will be used to differentiate those who respond to magnetic stimulation from those who do not. Impact on function, quality of life, and rates of progression to dementia will also be studied. A project modification was obtained to conduct a cross-sectional study, the COVID Dementia study. The cross-sectional study will examine the effect of the pandemic on MCI and AD patients and their caregivers ("individual COVID-related factors" such as, personally infected, death of a friend/family member, economic hardship, disruption in care, isolation), barriers to telehealth, caregiver distress, NPS, cognition (including onset of delirium), and function. Our goal is to develop a multi-pronged, remotely deliverable intervention to address consequences of healthcare disruptions in older Veterans with cognitive impairment. Aim 1. To explore the association between COVID-related factors and neuropsychiatric symptoms in individuals with MCI and AD. Hypothesis: The number of COVID-related factors endorsed by caregivers will be positively correlated with the severity of NPI-Q in individuals with MCI and AD. Aim 2. To assess cognition (telephonic version of the Montreal Cognitive Assessment; tMoCA12, and daily function (Functional Activities Questionnaire; FAQ13). Hypothesis: The number of COVID-related factors will be positively correlated with the severity of cognitive and functional deficits in individuals with MCI and AD. Aim 3. To explore the associations among COVID-related factors and caregiver distress. Hypothesis: Caregiver resilience and perceived social support will modify the association between COVID-related factors and severity of distress in caregivers.
