Types of Dementia
Most types of dementia are chronic, meaning that it can progress over a period of time. Some types of dementia include:
Alzheimer’s disease is the most common form of dementia, making up 60%-70% of the total number of dementia cases. This disease is a degenerative brain disease that initially affects a person’s ability to retain new information.
Impaired brain function caused by decreased blood flow to the brain (due to a stroke or other cardiovascular health problems) is usually referred to as vascular dementia. This type of dementia is the second most common form, next to Alzheimer’s disease.
Lewy Body Dementia (LBD)
Named after the neurologist Frederich H. Lewy, Lewy Body Dementia (LBD) is a form of dementia caused by an accumulation of microscopic brain deposits called “lewy bodies.” This form of dementia is the third most common form of dementia.
Frontotemporal dementia is a less common form of dementia that affects the frontal and temporal lobes of the brain.
Mixed Dementia is a form of dementia where a person’s brain simultaneously exhibits a combination of abnormalities from Alzheimer’s disease, vascular dementia, or LBD.
It’s important to note that most forms of dementia are often irreversible. Symptoms usually become worse over time.
Symptoms of Dementia
The signs and symptoms of dementia can differ from person to person. Symptoms can vary depending on a number of factors like the amount of damage to the brain, which parts of the brain are affected, and the person’s behavior before the onset of dementia.
