Improving Family Quality of Life Through Training to Reduce Care-Resistant Behaviors by People With AD and TBI

50 participants with possible or probable Alzheimer's disease dementia (of all severity stages) as defined by the NIA-Alzheimer's Association 2011 criteria will be enrolled, along with a family (i.e., unpaid) caregiver. A second cohort of 25 participants who have sustained moderate to severe TBI as diagnosed by UAB-TBIMS standards (generally Glasgow Coma Scale score of 12 or less at admission, cranial imaging with evidence of acute intracranial trauma, and/or post-traumatic amnesia duration of greater than 24 hours) ≥6 months prior to study entry (and their caregivers) will be enrolled. Entry is dependent on caregiver ratings on at least one of three behavioral domains of the Neuropsychiatric Inventory (NPI): 1) Agitation/Aggression, 2) Disinhibition, 3) Irritability /Lability. Based on standard scoring of the NPI, the caregiver must report all of these for at least one domain: * Frequency of "Often" (several times per week but less than every day) or more, * Severity of "Moderate" (stressful and upsetting; may require specific management) or higher * Distress of "Moderate" (fairly distressing, not always easy to cope with) or higher The caregiver must also report that the adverse behavior is triggered by resistance to care-related activities, e.g., bathing, taking medications, attending health-care appointments, etc. Additional inclusion criteria. * Age ranges AD: ≥ 50 years; TBI ≥ 19; Caregiver ≥18 * Sex distribution: both men and women. * Race: any. * Health: generall…
