From Nerve Damage to Neurological Symptoms
The individual parts of the CNS are associated with different regions of the body.
As you use the computer, your central nervous system (CNS) takes over various different functions. For instance it emits specific command signals which determine how your hand is to move the mouse. It also processes the images recorded by your eyes while reading. If the CNS has been damaged in some way by disease or injury, the location of the damage determines the kind of resulting symptoms. Damage in the spinal cord, for instance, can lead to a numb sensation and result in weakness of the limbs or bladder disorders. Damage to the optic nerves which connect the eyes to the brain often leads to restrictions in visual focus and colour recognition.
Other frequent symptoms resulting from damage to the CNS are:
• mobility disorders such as weakness, spasticity, stiffness, a feeling of heavy limbs
• abnormal sensory impressions such as numbness, pain, itching or burning.
In some cases no symptoms arise despite large-scale damage of the CNS. But usually there is a connection between the area of the damaged regions and the probability that symptoms will appear.
