Where can I get more information? What is peripheral neuropathy? Peripheral neuropathy refers to the many conditions that involve damage to the peripheral nervous system, the vast communication network that sends signals between the central nervous system the brain and spinal cord and all other parts of the body.
Peripheral nerves send many types of sensory information to the central nervous system CNSsuch as a message that the feet are cold. They also carry signals from the CNS to the rest of the body.
Best known are the signals to the muscles that tell them to contract, which is how we move, but there are different types of signals that help control everything from our heart and blood vessels, digestion, urination, sexual function, to our bones and immune system.
The peripheral nerves are like the cables that connect the different parts of a computer or connect the Internet. When they malfunction, complex functions can grind to a halt.
Nerve signaling in neuropathy is disrupted in three ways: The symptoms depend on the type of nerve fibers affected and the type and severity of damage.
Symptoms may develop over days, weeks, or years. In some cases, the symptoms improve on their own and may not require advance d care. Unlike nerve cells in the central nervous system, peripheral nerve cells continue to grow throughout life.
Some forms of neuropathy involve damage to only one nerve called mononeuropathy. Neuropathy affecting two or more nerves in different areas is called multiple mononeuropathy or mononeuropathy multiplex.
More often, many or most of the nerves are affected called polyneuropathy. Neuropathy is often misdiagnosed due to its complex array of symptoms.
More than types of peripheral neuropathy have been identified, each with its own symptoms and prognosis. Symptoms vary depending on the type of nerves—motor, sensory, or autonomic—that are damaged. Motor nerves control the movement of all muscles under conscious control, such as those used for walking, grasping things, or talking.
Sensory nerves transmit information such as the feeling of a light touch, temperature, or the pain from a cut.
Autonomic nerves control organs to regulate activities that people do not control consciously, such as breathing, digesting food, and heart and gland functions. Most neuropathies affect all three types of nerve fibers to varying degrees; others primarily affect one or two types.
Doctors use terms such as predominantly motor neuropathy, predominantly sensory neuropathy, sensory-motor neuropathy, or autonomic neuropathy to describe different conditions.
In severe cases, such neuropathies can spread upwards toward the central parts of the body. In non-length dependent polyneuropathies, the symptoms can start more toward the torso, or are patchy. What are the symptoms of peripheral nerve damage? Symptoms are related to the type of nerves affected.
Motor nerve damage is most commonly associated with muscle weakness. Other symptoms include painful cramps, fasciculations uncontrolled muscle twitching visible under the skin and muscle shrinking. Sensory nerve damage causes various symptoms because sensory nerves have a broad range of functions.
Damage to large sensory fibers harms the ability to feel vibrations and touch, especially in the hands and feet. You may feel as if you are wearing gloves and stockings even when you are not.
This damage may contribute to the loss of reflexes as can motor nerve damage. Loss of position sense often makes people unable to coordinate complex movements like walking or fastening buttons or maintaining their balance when their eyes are shut.
Small-fiber polyneuropathy can interfere with the ability to feel pain or changes in temperature. Neuropathic pain is sometimes worse at night, disrupting sleep. It can be caused by pain receptors firing spontaneously without any known trigger, or by difficulties with signal processing in the spinal cord that may cause you to feel severe pain allodynia from a light touch that is normally painless.Essay on Peripheral Neuropathy Disorder - Peripheral neuropathy is a term which describes damage to one or more of your peripheral nerves.
The damage means that the messages that travel between your central and peripheral nervous system are disrupted. There are many different conditions that can lead to peripheral neuropathy.
Leg cramps are often considered harmless, but these sudden and painful contractions are hard to ignore. They may subside in a few seconds, but the average duration is 9 minutes, and pain can.
Peripheral neuropathy is common among people with diabetes, causing loss of sensitivity in the hands and feet, and in organs such as the kidneys, heart, and eyes.
Peripheral neuropathy refers to the conditions that result when nerves that carry messages to and from the brain and spinal cord from and to the rest of the body are damaged or diseased.
