Problem 37

Background and context

There are about tens of billions of neurons present in a healthy human brain. These neurons aids in the processing and transmission of information through chemical and electrical signals. They send chemical or electrical signals or messages all over the body.

Alzheimer's is a brain disease that effectively destroys the connections of neurons involved in memory in the brain, as well as disturbs the connections in the entorhinal cortex and hippocampus. It also affects certain areas of the cerebral cortex that help with language, reasoning, and various social behaviors.
