Neurological Disorders
Neurological Disorders are conditions that affect the nervous system of the body. Commonly, these disorders will affect either the brain, the spine, or the various nerves throughout the body, all of which make up the central nervous system. There are so many causes of these that it is hard to list them all, but the main ones are caused by either genetics, hazardous environmental conditions, blunt force trauma, brain injury, diseases, infections, or poor nutrition. Just as protecting your eyesight involves good nutrition and a healthy lifestyle, so does protecting your brain. Neurological disorders are commonly known to affect the eyes, depending on the disorder. Migraines, for example, are a neurological condition that often starts with Photopsia, or flashing of lights in front of the eyes. Most of the time this will occur directly before a migraine headache takes place, but sometimes the flashing will happen with no headache afterward. This is considered neurological because migraines are caused by blood vessels going through spasms in the brain. Diseases like multiple sclerosis commonly have neurological effects on the eyes, and even viral infections like herpes can have a profound effect on eyesight. The following is a list of some of the most common neurological disorders found in humans:
Of course, this is just a few, as there are literally hundreds of known disorders that affect human beings. As much as they happen now, they would occur much more frequently if there weren't so many natural defenses in place by the body.
First of all, you have the skull, which can be several millimeters thick and serves to protect the brain from any trauma. Similarly, the bones of the spinal column protect the nerve clusters in the spine from suffering too much damage. As far as physical defenses go, those are the main ones. Chemically, the body employs what is known as a blood-brain barrier, which limits the number of chemicals that can be transferred from the bloodstream into the brain. This is the reason that a lot of nutritional and bodybuilding supplements don't quite work the way they are advertised. They are able to get into the bloodstream well enough, but that particular chemical is not able to pass this barrier, which acts like a sieve for all chemicals that don't fit. Even with all these protection measures in position though, the human central nervous system is still susceptible to a great many disorders and diseases. Also, even though neuroregeneration may happen in the peripheral nervous system, which is comprised of the outlying nerve clusters, most researchers believe that it doesn't actually happen in the central nervous system. That's why you always hear that your brain cells do not grow back. If you are experiencing any strange symptoms or changes in your vision, it's always best to go see a Eye Care Specialist or Eye Care Professional
to ensure that you do not have the beginning stages of some neurological disorder.
