Previous research has linked memory and thinking problems with visible changes that take place in the brain. People with Alzheimer’s have abnormal deposits of proteins called amyloid plaques and tau tangles. Plaques obstruct communication between nerve cells (or neurons) in the brain. Tau tangles disrupt processes in the cells and cause them to die.
