Key Facts About Dementia
- Dementia is a general term describing brain diseases that cause declines in memory, thinking, and behavior that interfere with daily life.
- Alzheimer’s Disease is the most common cause of dementia in older adults, but other types—such as Lewy Body Dementia, Frontotemporal Disorders, and Vascular Dementia—also contribute to cognitive decline.
- Symptoms often begin gradually. Individuals may show changes in behavior, personality, or problem-solving skills long before memory loss becomes apparent.
-
Many older adults have more than one underlying cause of dementia (known as mixed dementia). A specialist evaluation can help determine the most accurate diagnosis and guide appropriate support.

Pre-Clinical Alzheimer’s Disease
Research shows that Alzheimer’s Disease and other dementias may be preceded by a pre-clinical stage in which biological changes are present in the brain, spinal fluid, or blood, but no symptoms are yet apparent.
Individuals in this stage do not experience noticeable memory loss or cognitive decline. Ongoing research aims to better understand these early changes and their role in identifying disease before symptoms develop.

Mild Cognitive Impairment (MCI)
Some individuals experience Mild Cognitive Impairment (MCI), which involves memory or cognitive changes that are noticeable but do not interfere with daily functioning.
People with MCI are at increased risk of developing Alzheimer’s Disease or other dementias, although not all individuals with MCI progress to dementia.

Managing coexisting conditions such as depression or pain may improve overall functioning and well-being. Coordination of care between healthcare providers and informal caregivers, such as family members, can help maximize independence and quality of life for individuals living with dementia and those who support them.
Although there is no proven way to prevent dementia, staying physically active, eating a balanced and nutritious diet, and maintaining social engagement may help protect brain health or delay symptom onset.
Caregivers of individuals with dementia often provide more extensive assistance than caregivers for other chronic conditions and may experience increased burden. Social stigma related to dementia can contribute to isolation for both individuals and their families.
Early identification of dementia can help individuals and families plan more effectively as the disease progresses.
