Types of Alzheimer’s Disease

Alzheimer’s Disease is a progressive form of dementia that affects memory, thinking and behavior. It is the most common form of dementia, and is ranked among the top 10 leading causes of death in Canada. It is is a complex disease, and there are several different types that can be diagnosed.

The first type of Alzheimer’s is known as early-onset Alzheimer’s, which is diagnosed in people under the age of 65. Early-onset Alzheimer’s is relatively rare, but it is typically more aggressive, and can have a significant impact on a person’s daily life.

The second type of Alzheimer’s is late-onset Alzheimer’s. This is the most common type of Alzheimer’s that is diagnosed, and is found in those over the age of 65. Late-onset Alzheimer’s is typically slower and less aggressive compared to early-onset Alzheimer’s, but it can still have a major impact.

The third type of Alzheimer’s is known as familial Alzheimer’s. This form of Alzheimer’s is inherited, and is typically caused by a mutation on one of three genes. Familial Alzheimer’s is relatively rare, and tends to have an earlier onset than other forms of Alzheimer’s.

The fourth type of Alzheimer’s is known as posterior cortical atrophy. This form of Alzheimer’s is typically characterized by a slower onset and a more gradual decline in mental abilities. It is often associated with visual problems, such as difficulty recognizing faces or objects.

Finally, the fifth type of Alzheimer’s is known as mixed dementia. This type of Alzheimer’s is a combination of different types of dementia, such as vascular dementia and others. Mixed dementia is often harder to diagnose, so it is important to seek medical advice if you are exhibiting any signs or symptoms.

The most common signs and symptoms associated with Alzheimer’s are as follows:

1. Memory loss
2. Difficulty performing familiar tasks
3. Problems with speech
4. Disorientation
5. Poor or decreased judgment
6. Problems with abstract thinking
7. Misplacing things
8. Changes in mood or behavior
9. Changes in personality
10. Loss of initiative

No matter what type of Alzheimer’s you have, early diagnosis and treatment can help slow the progression of the disease and can help a person maintain their independence and quality of life for as long as possible. For more information on Alzheimer’s disease, as well as resources that can be of benefit to you and your family, visit the Alzheimer Society of Canada website at www.alzheimer.ca.
