Early onset Alzheimer's disease

Early onset Alzheimer's disease (pronunciation: /ˈɑːlts.haɪ.mər/), also known as Younger-onset Alzheimer's disease, is a form of Alzheimer's disease that affects individuals under the age of 65.

Etymology

The term "Alzheimer's" is derived from the name of the German psychiatrist and neurologist, Alois Alzheimer, who first described the disease in 1906. The term "early onset" is used to differentiate this form of the disease from the more common Late-onset Alzheimer's disease, which typically affects individuals over the age of 65.

Definition

Early onset Alzheimer's disease is a neurodegenerative disorder characterized by progressive memory loss, cognitive decline, and behavioral changes. It is a subtype of Alzheimer's disease, which is the most common form of dementia.

Symptoms

The symptoms of early onset Alzheimer's disease are similar to those of late-onset Alzheimer's disease, but they tend to progress more rapidly. They include memory loss, confusion, difficulty with speech and understanding, and changes in mood and behavior.

Causes

The exact cause of early onset Alzheimer's disease is unknown, but it is believed to be due to a combination of genetic, environmental, and lifestyle factors. Some cases are associated with mutations in the APP, PSEN1, and PSEN2 genes.

Diagnosis

Diagnosis of early onset Alzheimer's disease is based on clinical evaluation, neuropsychological testing, and brain imaging. Genetic testing may also be performed in some cases.

Treatment

There is currently no cure for early onset Alzheimer's disease, but treatments are available to help manage symptoms. These include medications, cognitive therapy, and lifestyle modifications.
