Patients with Alzheimer's disease have higher frequency of mental health symptoms which can precede memory problems, study finds

Decline in memory and other thinking abilities is the most well-known result of Alzheimer's disease (AD). However, many individuals with this condition also experience mental health symptoms such as agitation, depression, apathy, and trouble with sleep. A new study has found that the pathology behind AD may be a direct reason for emotional and behavioral symptoms. Additionally, they discovered when individuals with AD experience decline in memory and thinking abilities, their mental health tends to be worse.
