Familial Alzheimer’s disease (FAD) is a rare type of Alzheimer’s disease that affects families and is genetically inherited. It is estimated that only 1-5% of all Alzheimer’s cases are FAD. .
What is Familial Alzheimer’s Disease?
Familial Alzheimer’s disease is caused by mutations in one of three genes: PSEN1, PSEN2 or APP. These mutations cause the formation of amyloid plaques in the brain, which damage nerve cells and lead to memory loss and cognitive decline.
Most people with Alzheimer’s disease do not have a family history of the disease. However, for those who do, the risk of developing Alzheimer’s is greatly increased.
In fact, if one parent has the FAD gene, each of their children has a 50% chance of inheriting the gene and developing the disease.
Symptoms of Familial Alzheimer’s Disease
The symptoms of familial Alzheimer’s disease are similar to those of other forms of Alzheimer’s disease, but tend to appear at a younger age. In FAD, symptoms usually start appearing in a person’s 30s, 40s or 50s.
Some of the common symptoms of FAD include:.
- Difficulty with memory and thinking
- Losing things or misplacing items
- Difficulty planning and organizing
- Mood swings and changes in personality
- Difficulty with language and communication
- Loss of initiative and motivation
Diagnosing Familial Alzheimer’s Disease
If you suspect that you or a loved one may have familial Alzheimer’s disease, it is important to see a doctor. A doctor can perform tests to help determine the cause of the symptoms and develop a treatment plan.

Some of the diagnostic tests for FAD include:.
- Cognitive tests to evaluate memory and cognitive function
- Genetic testing to identify mutations in PSEN1, PSEN2 or APP genes
- Neurological exams to assess motor function and reflexes
- Brain imaging studies like MRI or PET scans to detect changes in brain structure and function
Treatment Options for Familial Alzheimer’s Disease
At present, there is no cure for familial Alzheimer’s disease. However, there are several treatments available to help manage the symptoms and improve the quality of life for individuals and families affected by the disease.
Some of the treatment options for FAD include:.
- Medications like cholinesterase inhibitors and memantine to improve cognitive function and slow the progression of the disease
- Behavioral and psychological therapies like cognitive-behavioral therapy and psychotherapy to help individuals cope with the emotional and cognitive changes associated with the disease
- Lifestyle changes like regular exercise, a healthy diet, and stress management to help improve overall health and well-being
- Support groups and counseling for individuals and families affected by the disease
Preventing Familial Alzheimer’s Disease
Because familial Alzheimer’s disease is caused by genetic mutations, it is not possible to prevent the disease entirely. However, there are some steps that individuals can take to help reduce their risk of developing the disease, including:.
- Eating a balanced, healthy diet
- Maintaining a healthy weight and exercising regularly
- Avoiding smoking and excessive alcohol consumption
- Managing chronic health conditions like hypertension and diabetes
- Staying mentally and socially active
Conclusion
Familial Alzheimer’s disease may be rare, but it can have a devastating impact on individuals and families affected by the disease.
Understanding the causes, symptoms, and treatment options for FAD can help individuals and families better cope with the challenges of this condition. While there is no cure for FAD, there are treatments available to help manage the symptoms and improve quality of life. Furthermore, healthy lifestyle choices can help reduce the risk of developing the disease in the first place.
