Degenerative spinal disorders involve a loss of function in the spine. Pressure on the spinal cord and nerves may be associated with herniation or disc displacement. Brain degeneration also causes central nervous system diseases (i.e. Alzheimer's, Lewy body dementia, Parkinson's, and Huntington's diseases).
Many viral infections of the central nervous system occur in seasonal peaks or as epidemics, whereas others, such as herpes simplex encephalitis, are sporadic. In endemic areas it is mostly a disease of children, but as the disease spreads to new regions, or nonimmune travelers visit endemic regions, nonimmune adults are also affected. [5]
Most cases of LKS do not have a known cause. Occasionally, the condition may be induced secondary to other diagnoses, such as low-grade brain tumors, closed-head injuries, neurocysticercosis, and demyelinating disease. Central nervous system vasculitis may be associated with this condition as well. [6]
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
As a stand-alone condition, "ataxia is a degenerative disease of the nervous system," explains Andrew Rosen, chief executive officer of the National Ataxia Foundation. There are many types ...
In children with this condition, these sugar molecules build up in the body and eventually lead to damage of the central nervous system and other organ systems. [2] Children with Sanfilippo syndrome do not usually show any problems at birth. As they grow, they may begin having trouble learning new things and might lose previously learned skills.
It belongs to a group of genetic disorders known as leukodystrophies, [1] where the growth and maintenance of myelin sheath in the central nervous system (CNS) are impaired. [2] There are three types of spongy degeneration: infantile, congenital and juvenile, with juvenile being the most severe type. [3]
