Among scientists and many lay people, it is well known that beta-amyloid is a destructive force to nerve cells in people suffering from Alzheimer’s disease. Beta-amyloid builds up in the brain, clumping in neurons and forming damaging deposits knows as plaque. This plaque is one of the hallmarks of Alzheimer’s disease.

In the disease process, the beta-amyloid damages and eventually kills neurons, brain cells. Many research studies have focused on the damaged nerve cells in trying to understand this process towards seeking a possible prevention and treatment.

In this new study, researchers from UCF looked at smaller amounts of beta-amyloid and its effect on healthy nerve cells. The scientists found that this more moderate exposure to the beta-amyloid has an effect on the cells, preventing the normal transfer of electronic signals in the brain.

The discovery is important in that it provides evidence that changes are occurring in the brain well before there are any noted changes to memory or behavior, that is, symptoms of the disease. This information may be valuable in the quest for a treatment that works in the earliest stages of the disease, suitable for an individual with the mild cognitive impairment.

More research is needed to fully understand the role of beta-amyloid in Alzheimer’s disease as well as potential treatments.
