What happens when stroke occurs?
The brain controls all of the body’s functions, including motor, sensory, balance, speech, and cognition. The cerebral hemisphere is composed of four large lobes, each of which can be subdivided into many functional areas.
The brain consists of nerve cells called neurons and glial cells which are interconnected, They are responsive cells in the nervous system that process and transmit information by electrochemical signaling. An adult human brain has more than 100 billion neurons.
When the blood supply to part of the brain is interrupted by either an ischemic or hemorrhagic event, the bodily functions controlled by that particular part of the brain are disrupted. This leads to disabilities.
