Diseases

There are many diseases that the nervous system and the brain can be heavily damaged. One of these diseases is called brain cancer. Brain cancer starts to form tumors in the the brain that takes space and damages the brain. It starts to destroy parts of the brain which cause the person to start losing thoughts, actions, and memory's. Another disease is called a stroke. A stroke is when blood spills on the brain damaging it badly if not caught early. Most strokes happen in the elderly but sometimes in younger people. Another disease is called encephalitis, it is a more common disease than others. It is an inflammation of the brain. Another disease is called Alzheimers disease. This a disease that eats away at your brain causing it to lose memory's and skills. Causes of this disease are usually your genetics. Symptoms are forgetfulness, disorientation, language, and judgment.

Interaction with other systems

The nervous system interacts with other systems using different ways. The nervous system has thousands of neurons that connect the nervous system to all the other systems. The nervous system uses is neurons to talk and communicate to other systems. It tells them what to do. It acts like the general of an army because it controls all the other systems and tells them to do their part.
