Alzheimer’s disease
An imbalance of dietary habits can be a problem for the nervous system. Ageing is a natural process that so far no one can avoid. As people age, their bodies cannot fully metabolise harmful substances as before, and consequently accumulate in the body. Sometimes, these substances cause cancers in different organs, and sometimes they cause neurodegeneration in the brain. The most common neurodegeneration disease is Alzheimer’s
There are two kinds of Alzheimer’s disease that may happen at different ages. The first one is genetic Alzheimer’s disease, which is less common. The second kind of Alzheimer’s disease is sporadic Alzheimer’s disease, which is the major Alzheimer’s disease. It accounts for more than 65 % of Alzheimer’s disease patients at the age greater than 65 years old.
Compared to the normal brain, Alzheimer’s disease patient’s brain is shrunk. In an AD brain, extreme shrinkage of the cerebral cortex and the hippocampus as well as severely enlarged ventricles were observed.
