Alzheimer's brain
Alzheimer's brain. Computer processed vertical (coronal) slice through the brain of an Alzheimer patient (at left) compared with a normal brain (at right). The Alzheimer's disease brain (brown) is considerably shrunken,due to the degeneration and death of nerve cells. Apart from a decrease in brain volume,the surface of the brain is often more deeply folded. Tangled protein filaments (neurofibrillary tangles) occur within nerve cells and patients also develop brain lesions of beta-amyloid protein. Alzheimer's disease accounts for most cases of senile dementia. Symptoms include memory loss,disorientation,personality change and delusion. It ultimately leads to death
