Amyloid beta is a normal protein peptide in the human brain, but these particles are chemically “sticky” and gradually build up into plaques, or tough fibril-like structures called amyloid plaques in the brains of people developing Alzheimer's disease. The small clumps may block cell-to-cell signaling at synapses. They may also activate immune system cells that trigger inflammation in the brain.

It's an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities. Alzheimer's disease is the most common type of dementia.... More, ADRC researchers see a window of opportunity to leverage lifestyle changes or new medications to intervene in this early disease process. Clinical trial efforts are underway, at sites such as the ADRC, to test the efficacy of drugs to remove or prevent amyloid beta buildup, and their potential to reduce or delay the onset of A diminished mental capacity, such as difficulty with short-term memory. Problems that affect how clearly a person thinks, learns new tasks, and remembers events that just happened or happened a long time ago. Problems that affect cognition.
