Although it can be caused by several medical conditions, a diagnosis of chronic ischemic gliosis means that there are scars along the central nervous system that are impeding blood flow to the surrounding nerves, tissues and organs. Scars such as these, which are also called lesions, are present in many conditions such as multiple sclerosis and are often found after a stroke.Know More
The scarring process called gliosis occurs after neurons are damaged and die as a result of some sort of disease or traumatic event. After death, neurons are replaced with a dense fibrous network of neuroglia or supporting cells. The condition is chronic, meaning that it does not go away and continues to cause impairment over a long period of time.
Made up of the brain, spinal cord and peripheral nerves, the central nervous system is extremely complex and does not heal very well, which often results in chronic conditions. This means that once damage occurs, it rarely becomes better on its own. Fortunately, many ongoing studies hope to shed some light on the matter and lead to breakthroughs that will allow doctors to heal lesions that occur in debilitating diseases such as Parkinson's disease, multiple sclerosis, ALS and others.Learn more about Conditions & Diseases
Devic's disease is a disorder of the central nervous system in which the eye nerves and the spinal cord become swollen, according to the Mayo Clinic. It is also known as neuromyelitis optica.Full Answer >
A demyelinating disease is a condition such as multiple sclerosis that damages the myelin sheath protecting the nerve fibers in the central nervous system, as stated by Mayo Clinic. This can cause the slowing or complete halting of nerve impulses, leading to neurological symptoms.Full Answer >
Tarlov cysts are sacs of fluid that affect the nerves at the spinal base. They are also known as perineural cysts and rarely cause symptoms, which means they are not easily noticeable, notes Heathline. However, when the symptoms appear, they usually manifest in lower back pain and pain in the legs and buttocks.Full Answer >
Peripheral neuropathy in the leg is damage to the nerves that regulate temperature, pressure and pain perception, and muscle strength, according to WebMD. The neuropathy typically begins as loss of feeling and pain in the toes, and as it worsens, the damage spreads to the legs.Full Answer >
