Parkinson's Disease Dementia An estimated 50 to 80 percent of those with Parkinson's eventually experience dementia as their disease progresses.

Early-onset Alzheimer's: When symptoms begin before age 65 Early-onset Alzheimer's is an uncommon form of dementia that strikes people younger than age 65. Of all the people who have Alzheimer's disease, about 5 percent develop symptoms before age 65. So if 4 million Americans have Alzheimer's, at least 200,000 people have the early-onset form of the disease. Most people with early-onset Alzheimer's develop symptoms of the disease in their 40s and 50s.

The Three Most Common Types of Dementia and Their Differences This is a type of dementia that, like Alzheimer’s disease, causes loss of memory and cognitive abilities and most commonly affects patients over the age of 60. But unlike Alzheimer’s where the symptoms come on gradually, the symptoms of vascular dementia may come on more quickly, with memory loss being one of the last symptoms to appear.

What is Alzheimerâs Disease? For information about Memory Disorder Clinics and the Florida Brain Bank, see Clinical Evaluation and Research. It is very rare to show signs of dementia before age 40, however the youngest person ever diagnosed with Alzheimer’s was 27 years of age. Alzheimer’s and Down’s Syndrome are both on chromosome 21, and patients who have Down’s Syndrome invariably develop Alzheimer’s if they live long enough.

Dementia Dementia is a loss of brain function that occurs with certain diseases. It affects memory, thinking, language, judgment, and behavior. Dementia usually occurs in older age. It is rare in people under age 60. The risk of dementia increases as a person gets older. Most types of dementia are nonreversible (degenerative). Nonreversible means the changes in the brain that are causing the dementia cannot be stopped or turned back. Alzheimer disease is the most common type of dementia. Another common type of dementia is vascular dementia. It is caused by many small strokes. Lewy body disease is a common cause of dementia in the elderly. People with this condition have abnormal protein structures in certain areas of the brain.

What can cause memory problems? Having a parent, brother or sister with Alzheimer’s disease may increase your own chances of developing the condition very slightly, but it does not mean dementia is inevitable for you. Does dementia only affect older people? The chances of developing dementia increase as we get older and it is uncommon to get dementia before 65 years of age. However at least 42,000 people in the UK under 65 have dementia. This is sometimes referred to as ‘young-onset dementia’. Related information: Worried about your memory?

dementia The prevalence of dementia is difficult to determine, partly because of differences in definition among different studies and partly because there is some normal decline in functional ability with age. The prevalence of dementia roughly doubles for every five years of age beginning at age 60.

- When people are diagnosed with Alzheimer’s at about age 60 or 65, they generally decline more slowly. Their life expectancy is then on the order of 12 or 14 years, and some may even live up to 20 years longer. But when people are diagnosed at age 80 or 85, their Alzheimer’s tends to progress more rapidly. Their advanced age also increases the probability of their death, and they generally survive only 5 to 8 years.

- While the likelihood of having dementia increases with age, it is not a normal part of aging. Light cognitive impairments, such as poorer short-term memory, can happen as a normal part of aging. This is known as age-related cognitive decline rather than dementia because it does not cause significant problems.

Overview Dementia is more common in people over the age of 65, but it can also affect younger people. Early onset of the disease can begin when people are in their 30s, 40s, or 50s. With treatment and early diagnosis, you can slow the progression of the disease and maintain mental function.
