Can Alzheimer’s Be Genetically Passed Down?


Yes, Alzheimer’s can can be genetically passed down. It is believed that many factors influence the start and progression of Alzheimer’s disease. One of the most important factors is genes. Early-onset familial Alzheimer’s disease is an inherited genetic disorder. There are some diseases which are caused by genetic mutation or permanent change in one or more specific genes.

Symptoms Start Occuring Around Ages 30-60

How Gene Variants In Alzheimer Detection Works

When a person inherits a genetic mutation that causes a certain disease from the parent, then he or she will get the disease. This explains why Alzheimer’s can indeed be passed down.

With some diseases, there are genetic variants where a single gene can have many variants and these genetic variants can cause a disease either directly or indirectly. In many cases, a variant will increase or decrease the risk of a person developing a disease or condition. In the case where the variant increase the risk of the disease but does not directly cause the disease, it is called a genetic risk factor.

This is why identifying genetic variants is helpful for researchers to find the most effective ways to treat or prevent Alzheimer’s.

The two types of Alzheimer’s: early-onset familial Alzheimer’s (FAD) and late-onset have a genetic component. Early-onset Alzheimer’s which occurs in people in their 30s to mid-60s is an inherited disease. If a child’s biological parent carries a genetic mutation for early-onset Alzheimer’s FAD, then they have a 50/50 chance of inheriting that mutation. For late-onset Alzheimer’s for people in their late 60s, genetics alone cannot be attributed to the cause of the disease. Other factors like environment and lifestyle of the person affect their risk of developing the disease.

Can Alzheimer’s Be Reversed?

There have been recent developments that suggest that there is a possibility of reversing the memory loss that occurs in Alzheimer’s disease.

Devoted Guardians'
Response to COVID-19

Devoted Guardians is actively monitoring the progression of the coronavirus, COVID-19, to ensure that we have the most accurate and latest information on the threat of the virus. As you know, this situation continues to develop rapidly as new cases are identified in our communities and our protocols will be adjusted as needed.

While most cases of COVID-19 are mild, causing only fever and cough, a very small percentage of cases become severe and may progress particularly in the elderly and people with underlying medical conditions. Because this is the primary population that Devoted Guardians serves, we understand your concerns and want to share with you how our organization is responding to the threat of COVID-19.

We are following updates and procedures from the Centers for Disease Control (CDC) State Department of Health, local and county authorities, the Home Care Association of America and other agencies and resources. Our response and plans may adjust according to the recommendations from these organizations.
