Visceral pain is often described as generalized aching or squeezing. It is caused by compression in and around the organs, or by stretching of the abdominal cavity. Sometimes visceral pain may radiate to other areas in the body, making it even harder to pinpoint its exact location.
Data from the largest analysis to date of amyloid plaques showed they can appear 20 or 30 years before dementia symptoms.
Brain Tour. 11. More about plaques. Plaques form when protein pieces called beta-amyloid (BAY-tuh AM-uh-loyd) clump together. Beta-amyloid comes from a larger protein found in the fatty membrane surrounding nerve cells. Beta-amyloid is chemically sticky and gradually builds up into plaques.The most damaging form of beta-amyloid may be groups of a few pieces rather than the plaques themselves.rain Tour. 11.
