The brain, mind, and body are a single unit which cannot be separated. Any alteration in the brain affects the bodily functions. Any physical condition can cause changes in the mind and the brain.
Research has proven that this mind-body connection is vital for the overall functioning of a human being. The mind and the body are not separate. What affects one affects the other.
