Nervous system disease - Nervous system disease - Infections: Although the blood-brain barrier protects the nervous system from microorganisms, it may be damaged by bacteria, viruses, fungi, and other organisms. The myelin sheath is the protective, fatty coating surrounding your nerve fibers, similar to the protective insulation around electrical wires. This coating enables the electrical impulses between nerve cells to travel back and forth rapidly. Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare neurological disorder in which there is inflammation of nerve roots and peripheral nerves and destruction of the fatty protective covering (myelin sheath) of the nerve fibers. For example, PM2.5 can destroy the integrity of the blood-brain barrier (BBB), so peripheral systemic inflammation easily … They fear lifting heavy weights too often near their one-rep max (1 RM) in the big compound exercises. Peripheral nervous system (PNS) — Nerves that are outside of the brain and spinal cord. If the autoimmune conditions are not treated properly with peripheral neuropathy therapy, it can destroy your connective tissues, joints, organs etc., making the nerve fibers vulnerable. Unfortunately, these infections are often serious and life threatening. These cells, known as neurons, are crucial to transmitting the electrical and chemical signals that we need to maintain and perform essential bodily functions.

It includes the ganglia, nerves, and receptors, as they are found in various parts of the body. Oncologists are generally well aware of the toxicity of the main agents, but fear the side effects of new drugs. These nerves extend from the central nervous system to the outermost areas of the body. In gross anatomy, the nervous system can be divided into distinct organs, these being stations through which the Peripheral neuropathy (PN) occurs when any of the nerves in your peripheral nervous system become damaged, irritated, or inflamed. Stress causes the endocrine system to release hormones that have quick and wide-ranging effects throughout the body. Damage to the peripheral nerves can cause progressive weakness and loss of sensation in the arms and legs. Some serious conditions, diseases, and injuries that can cause nervous system problems include: Blood supply problems (vascular disorders). Selected Health Conditions and Likelihood of Improvement with Treatment identifies and defines the professionally accepted, standard measurements of outcomes improvement for medical conditions. Peripheral neuropathy describes damage to the peripheral nervous system, the vast communications network that transmits information from the brain and spinal cord (the central nervous system) to every other part of the body. Chronic stress can overwhelm the nervous system. Neurologic complications are well recognized and cause a distinct increase in morbidity. The book surveys the principal epidemics around the world and across the centuries, in each case discussing the origins of the outbreaks, the symptoms, the mortality rate and the social and economic effect. aka INFECTIOUS POLYNEURITIS, is an inflammation of the myelin sheath of peripheral nerves, characterized by rapidly worsening muscle weakness that can lead to temporary paralysis. The Central Nervous System (CNS) and the Peripheral Nervous System (PNS) are the two systems that make up the Nervous System. Symptoms may be mild or severe. “What we are learning is how the virus gets into the nervous system to establish life-long infections. 10,12 MDMA-exposed primates showed reduced numbers of serotonergic neurons 7 years later, indicating that some of MDMA’s effect on the brain can be long lasting. The degeneration of these nerve endings, which convey sensory information like temperature, pain and mechanical stimulation to the central nervous system… The human nervous system can be identified as two subsystems, one is the central nervous system (CNS) and the other is the peripheral nervous system (PNS). This Volume of the series Cardiac and Vascular Biology offers a comprehensive and exciting, state-of-the-art work on the current options and potentials of cardiac regeneration and repair. Peripheral neuropathy can have several sources and labs should be done to rule out causes such as GBS (Misra, Kalita & Nair, 2008). Besides, if you are someone who has had diabetes for long, you are more susceptible to getting the condition. Overactive bladder. Introduction.
