Early-onset Alzheimer's disease
Early-onset Alzheimer's disease
Early-onset Alzheimer's disease (pronunciation: /ˈɑːlts.haɪ.mər/), also known as Early-onset Alzheimer's, 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 prefix "early-onset" is used to differentiate this form of the disease from the more common late-onset Alzheimer's, 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, but they tend to progress more rapidly. They include memory loss, confusion, difficulty with speech and understanding, and changes in mood and behavior.
Causes
While the exact cause of early-onset Alzheimer's disease is unknown, it is believed to be largely genetic. Most cases are associated with mutations in one of three genes: the PSEN1, PSEN2, or APP genes.
Diagnosis
Diagnosis of early-onset Alzheimer's disease is based on a combination of clinical assessment, 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. Treatment focuses on managing symptoms and improving quality of life. This may include medication, cognitive therapy, and lifestyle changes.
