Neurological symptoms often originate in the peripheral nervous system and include burning, numbness, pins-and-needles (prickling) sensations, muscle weakness or paralysis, and sensitivity. These symptoms may be caused by a local injury when the pain can be directly related to a trauma or a systemic illness that affects your entire body. Symptoms of a neurological disorder can be mild, such as muscle weakness, poor coordination, or changes in thinking patterns. Symptoms can also be more noticeable, such as seizures, pain, and intellectual disability. People with a neurological disorder can have just one or many of these symptoms. The causes of neurological problems are genetic disorders, congenital abnormalities, infections, environmental health problems including malnutrition, and brain injury, spinal cord injury or nerve injury. The problem may start in another body system that interacts with the nervous system. The nervous system’s ability to effectively communicate with other areas of the body becomes hindered as nerve fibers begin to die off and as scar tissue begins to accumulate because of the ongoing deterioration of the central nervous system.
