What are the signs of neurological problems?
Neurological symptoms are symptoms caused by, or occurring in, the nervous system. The nervous system consists of two anatomic parts. The central nervous system, which includes the brain and spinal cord, acts as a central processing station. The peripheral nervous system transmits sensory information between the muscles, tissues and nerves in the rest of the body to the brain. When these connections are disrupted, neurological symptoms occur.
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. With referred pain, a more complex condition, the sensation of pain is felt in a different part of your body from where the injury or illness actually occurred. Referred pain is the most difficult to diagnose and treat.
Neurological symptoms can arise from one nerve or many. Some syndromes, such as carpal tunnel syndrome, occur when a nerve is compressed and deprived of proper blood flow. Diabetes is a common cause of peripheral neuropathies (nerve disorders), the result of nerve damage from high blood sugar. Neurological symptoms can stem from autoimmune diseases (such as lupus or Guillain-Barré syndrome) or viruses such as the human immunodeficiency virus (HIV), Epstein-Barr, or varicella-zoster.
Neurological symptoms due to a malfunctioning of the autonomic nervous system (part of the peripheral nervous system) may interrupt involuntary actions such as breathing, swallowing, bladder control, or perspiration. They may be accompanied by symptoms of low blood pressure, such as dizziness or vertigo, or loss of consciousness. Seek immediate medical care (call 911) if you, or someone you are with, have any of these symptoms, as they can be life threatening.
What other symptoms might occur with neurological symptoms?
Neurological symptoms may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. Neurological symptoms are diverse because the nervous system governs or participates in a number of functions as well as body systems, including control of body temperature, blood pressure, muscles, digestion and appetite, movement, and sight.

What causes neurological symptoms?
The causes of neurological symptoms are as diverse as the nervous system itself. A common origin for neurological symptoms is the peripheral nervous system, which transmits sensory signals from the rest of the body to the central nervous system (brain and spinal cord).
