Young-onset Alzheimer’s disease has a strong genetic component. So far, researchers have linked the condition to mutations in one of three genes: APP, PSEN1, or PSEN2, which account for about 10 percent of all young-onset cases. When any of these genes is altered, the brain produces large amounts of amyloid beta peptide, a toxic protein fragment that clumps together to form amyloid plaques, a key marker of the disease, says Richard Sherva, PhD, research assistant professor at Boston University School of Medicine. These clusters bind themselves to receptors on nerve cells, triggering a process that erodes their synapses with other nerve cells, says Dr. Sherva.

People ask why it is important to seek medical attention if they are suspicious that a loved one might have the beginning stages of some form of dementia. Getting a proper, accurate diagnosis is important for many, many reasons. Don’t ignore what “your gut feeling” is telling you. Seek medical consultation and evaluation. Doreen 10/15/18
