Many conditions and diseases cause dementia. Alzheimer's is the most common cause. Other causes include brain changes that lead to vascular dementia, Lewy body dementia, and frontotemporal disorders.
Doctors diagnose dementia—including Alzheimer disease, Lewy body dementia, and frontotemporal dementia—with brain scans and other tests.
Vascular contributions to cognitive impairment and dementia (VCID) affect memory, thinking, and behavior. Learn about forms of VCID and modifiable risk factors.
Find articles, fact sheets, and other resources to help you and your family learn about vascular dementia and vascular cognitive impairment.
Read about mixed dementia, a combination of two or more types of dementia. For example, older adults with dementia may have Alzheimer’s and vascular dementia.
A type of dementia called FTD tends to strike before age 65 and stems from damage to the brain’s frontal lobe and temporal lobe. Learn more about FTD and brain changes from NIH.
Read about types of FTD. One type involves changes in personality, behavior, and judgment. Primary progressive aphasia affects language and PSP, movement.
What causes frontotemporal disorders? In most cases, we don’t know. In other cases, gene mutations lead to this early-onset brain disease. Learn more from NIH.
Find out how a doctor diagnoses frontotemporal dementia and related disorders. Get a list of medical centers where you can get an FTD diagnosis.
Possible symptoms of frontotemporal disorders include behavior problems, language symptoms like aphasia, emotional troubles, and movement changes.
Drugs, along with other therapies, can help treat the behavior, language, and movement symptoms of FTD. So far, there is no cure. Learn more from NIH.
Get advice on providing care for a person with frontotemporal dementia or similar disorder. Learn how to manage home, family, work, and long-term care issues.
Find websites, publications, videos, and other resources to help you and your family learn about the major types of frontotemporal disorders.
What is Lewy body dementia (Lewy body disease)? It is a brain disorder, different from Alzheimer’s, that causes changes in thinking and movement.
Did you know Lewy body dementia has two types? Dementia with Lewy bodies and Parkinson’s disease dementia differ in the order of cognitive and movement symptoms.
Learn about causes and risk factors for Lewy body dementia. They include an accumulation of Lewy bodies in the brain, age, Parkinson’s disease, and genetics.
Do you know the symptoms of Lewy body dementia? They may include cognitive and mood changes, Parkinson symptoms, sleep disorders, and hallucinations.
Lewy body dementia is often misdiagnosed as Alzheimer’s or Parkinson’s. See a doctor to find out what’s causing your symptoms and get the right treatment.
Treatment for Lewy body dementia may include medications to help control symptoms, physical therapy, and counseling. Use certain drugs with caution.
Getting help from family, friends, doctors, and other professionals ensures the best possible care and quality of life for a person with Lewy body dementia.
Family members who care for someone with Lewy body dementia can get support to maintain health and help doctors and others understand the disease.
Research on Lewy body dementia seeks deeper understanding of this brain disease and how it relates to related types of dementia. Learn how to get involved.
