Alzheimer’s disease causes irreversible, progressive degenerative brain changes that may lead to unpredictable behaviors and profound cognitive, memory, problem-solving, and communication diffi culties ( Alzheimer’s Association [AA], 2019b , 2019c ; National Institute on Aging, 2019 ). Those who are affected gradually lose their ability to read a newspaper, drive a vehicle, and even feed themselves, causing the need for a full-time caregiver. Aging is the leading risk factor for diagnosis; however, aging does not cause the disease, nor is diagnosis a normal process of aging ( AA, 2019a ; World Health Organization, 2017 ).
