Brain & Nervous System

The Glasgow Coma Scale is a common scoring system that physicians and emergency responders use to asses a patient's mental consciousness. The test is based on a 15-point scoring scale. Lower...

The motor neurons control all voluntary muscle functions in the body. It can be difficult to diagnose a motor neuron disease because the early symptoms mimic those of several other diseases, and...

Motor neurons disease is a condition that attacks the nervous system and could potentially cause paralysis, but it does not affect the involuntary bodily functions needed to survive such as...

Dopamine, a neurotransmitter, can affect parts of the brain. Often associated with depression and chronic fatigue syndrome, dopamine levels can affect more than a person's mood. Movement and motor...

Motor neuron disease is a condition that causes the gradual deterioration of your ability to control the muscles in your body. It can develop into various other conditions including Lou Gerhig's...

Parkinson's disease is considered a brain disorder caused by damaged or dying nerve cells that are supposed to create dopamine, which provides coordinated muscle movement. Without dopamine,...

The nerves play a very important role within the human body: They help regulate a person's breathing, stimulate movement by the muscles and allow the body to differentiate between heat and cold....

Motor skills disorders are neurological problems that affect the child's ability to move his body in the way he wants it to move. He may have had this problem from birth or it may have developed...

Cerebral palsy is a neuromuscular disorder that causes sufferers to have severe difficulties with movement, particularly motor skills. There are a number of types and levels of conditions defined...

In short, motor units are what allows our body to move. They are activated and contract once they have been signaled by the body to do so and, like a well-oiled machine, one motor unit will signal...

Amyotrophic Lateral Sclerosis (ALS), or Lou Gehrig's disease, is a progressive condition that destroys the motor neurons in the brain and spinal cord. This prohibits the brain from being able to...

Difficult to diagnose, simple partial seizures do not result in a loss or change of consciousness. Abnormal electrical activity in a specific portion of the brain causes simple partial seizures....

There are three kinds of ataxia. The first is called hereditary ataxia; often found in children and is passed down genetically. The second type is sporadic ataxia, developing later in life with no...
