Central Nervous System

There are two main components of the nervous system: The brain and the spinal cord. When these are combined, this is known as the Central Nervous System, also commonly referred to as CNS. In addition, the nervous system also contains sensory and motor nerves. When combined, this is known as the Peripheral Nervous System (PNS). These nerves send information to the body, which helps us perform everyday functions, such as movement, as well as help us interpret how we feel pain.

The nervous system is made up of three types of neurons: Motor neurons, which are responsible for controlling much of how your body operates, including organ function and the contraction of muscles. Sensory neurons, which are responsible for our five senses such as hearing, smell, sight, taste and touch; as well as the Interneurons, which help the motor and sensory neurons to communicate.

There are a wide variety of disorders that are associated with the central nervous system. For example, fibromyalgia; a common but complex condition that causes pain throughout the body. Alzheimer’s disease is another common disorder that is associated with the CNS. You can find in-depth information on this and other cognitive disorders from Vancouver physician, Dr. Ali Ghahary, on Blogspot.

Other CNS-related disorders include the following:

Bell’s Palsy – A condition that causes the facial muscles to become weak or paralyzed. Symptoms of Bell’s Palsy include a lack of facial expression or noticeable drooping of one side of the face.

Disk Disorders – This occurs when the intervertebral disks found between the spinal vertebrae deteriorate, resulting in pain in the back, neck and legs, which can oftentimes be severe. In order to reduce pain, medication such as ibuprofen or acetaminophen is often recommended by Dr. Ali Ghahary, in conjecture with muscle relaxers, bed rest, and the application of hot or cold (such as heating pads and ice packs.) Massage therapy may also be beneficial.

Encephalitis – A condition that causes inflammation of the brain, which is usually the result of a viral infection. Symptoms of encephalitis include headache, sensitivity light, fever, a stiff neck and/or back drowsiness, irritability, confusion, and clumsiness. Loss of consciousness and seizures can also occur as a result of encephalitis, which may indicate it has become life threatening. Those most at risk of developing encephalitis are infants and seniors. In order to treat this condition, hospitalization is usually required along with antibiotics and steroids to help decrease the inflammation.

Headaches – Another common disorder of the central nervous system. There are various types of headaches that an individual can suffer from, such as tension headaches and cluster headaches, as well as a more severe form of headache known as migraine headaches. You can find more information on headaches by visiting Dr. Ali Ghahary’s website at alighaharyvancouver.ca.

Neuralgia – A term that is used to describe general nerve pain. This kind of pain can be severe, and is often described as a burning or shooting sensation. There can be many causes of neuralgia – however, the most common causes include trauma (surgery, for example), as well as infections.

Parkinson’s Disease – Currently affecting as many as 1 in every 500 Canadians, Parkinson’s is a progressive disorder that results in degeneration of the brain’s nerve cells, leading to lack of control over body movement. Dr. Ali Ghahary shares more information on Parkinson’s disease on his website, along with various resources to help individuals cope with a diagnosis of Parkinson’s.

These are just a few examples of some of the many disorders that can affect the body’s nervous system.
