Alzheimer’s disease is a progressive form of dementia. Dementia is a broader term for conditions that negatively affect memory, thinking, and behavior. The changes interfere with daily living. Dementia can have a range of causes, such as brain injuries or diseases. Sometimes the cause is unknown.
According to the Alzheimer’s Association, Alzheimer’s disease accounts for 60 to 80 percent of dementia cases. Most people with the disease get a diagnosis after age 65. If it’s diagnosed before then, it’s generally referred to as “younger onset” or “early onset” Alzheimer’s disease.
There’s no cure for Alzheimer’s, but there are treatments that can slow the progression of the disease.
Everyone has episodes of forgetfulness from time to time. But people with Alzheimer’s disease display certain ongoing behaviors and symptoms that worsen over time. These can include:
These signs don’t always mean that a person has Alzheimer’s. It’s important to see a doctor to determine the cause.
Symptoms change according to the stage of the disease. In later stages, people with Alzheimer’s often have significant trouble with talking, moving, or responding to what’s happening around them.
Experts haven’t determined a single cause of Alzheimer’s disease, but they have identified certain risk factors, including:
Having one or more of these risk factors doesn’t mean that you’ll develop Alzheimer’s disease. It simply raises your risk level.
Other possible risk factors include a history of:
There is no known cure for Alzheimer’s disease. It is not possible to reverse the death of brain cells.
Treatments can, however, relieve its symptoms and improve quality of life for the person and their family and caregivers.
The following are important elements of dementia care:
The emotional and behavioral changes linked with Alzheimer’s disease can be challenging to manage. People may increasingly experience irritability, anxiety, depression, restlessness, sleep problems, and other difficulties.
Treating the underlying causes of these changes can be helpful. Some may be side effects of medications, discomfort from other medical conditions, or problems with hearing or vision.
Identifying what triggered these behaviors and avoiding or changing these things can help people deal with the changes. Triggers may include changing environments, new caregivers, or being asked to bathe or change clothes.
It is often possible to change the environment to resolve obstacles and boost the person’s comfort, security, and peace of mind.
