Motor neuron diseases develop when the nerve cells that control voluntary muscle movement degenerate and die, causing weakness in the muscles they control. PLS only affects upper motor neurons. [1] There is no evidence of the degeneration of spinal motor neurons or muscle wasting that occurs in amyotrophic lateral sclerosis (ALS).
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 ...
Based on the person's symptoms and findings from the examination and from these tests, the physician may order tests on blood and urine samples to eliminate the possibility of other diseases, as well as routine laboratory tests. In some cases, for example, if a physician suspects the person may have a myopathy rather than ALS, a muscle biopsy ...
Older patients affected with the cerebral form will present with similar symptoms. Untreated, cerebral ALD is characterized by progressive demyelination leading to a vegetative state and death. [2] Adult males with an adrenomyeloneuropathy presentation typically present initially with muscle stiffness, paraparesis and sexual dysfunction. [3]
Symptoms for spinal tumors may vary due to factors such as the type of tumor, the region of the spine, and the health of the patient. Back pain is the most common symptom and it can be a problem if the pain is severe, has a time frame that lasts longer than it would for a normal injury, and becomes worse while laying down or at rest.
The disorder is sometimes called chronic relapsing polyneuropathy (CRP) or chronic inflammatory demyelinating polyradiculoneuropathy (because it involves the nerve roots). [2] CIDP is closely related to Guillain–Barré syndrome and it is considered the chronic counterpart of that acute disease. [ 3 ]
Less commonly, the cause of spinal stenosis may be present at birth as seen in achondroplasia, spina bifida, and certain mucopolysaccharidoses. [15] In addition to spinal stenosis, other lower back conditions such as spondylosis, tumors, infections and herniated or ruptured discs can cause NC. These conditions contribute to the potential ...
