Sundowning is a pattern of worsening behavioral symptoms in the late afternoon and evening, likely linked to circadian rhythm disruption.

Engaging in regular physical exercise and mentally stimulating activities can help reduce the risk of Alzheimer's disease by promoting brain health and cognitive reserve. These activities improve blood flow to the brain, reduce inflammation, and encourage the growth of new brain cells and connections. A healthy lifestyle, including a balanced diet and avoiding smoking, also contributes to brain health.

Neuroimaging techniques, such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scans, are commonly used to support an Alzheimer's diagnosis. MRI can detect brain shrinkage and rule out other causes of cognitive decline, while PET scans can identify amyloid plaques, tau tangles, or show reduced brain metabolism characteristic of the disease. These methods help confirm the presence of changes associated with Alzheimer's.

Anosognosia is a neurological condition where the person with dementia has no awareness of their own impairments, differing from denial.
