Schilder disease or diffuse myelinoclastic sclerosis: is a rare disease that presents clinically as a pseudotumoural demyelinating lesion; and is more common in children. [56] [57] Solitary sclerosis: This variant was proposed (2012) by Mayo Clinic researchers. [58] though it was also reported by other groups more or less at the same time.
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 ...
Motor neuron diseases affect both children and adults. [5] While each motor neuron disease affects patients differently, they all cause movement-related symptoms, mainly muscle weakness. [6] Most of these diseases seem to occur randomly without known causes, but some forms are inherited. [2]
It has been suggested that multifocal motor neuropathy is distinct from chronic inflammatory demyelinating polyneuropathy and that Lewis-Sumner syndrome is a distinct variant type of chronic inflammatory demyelinating polyneuropathy. [53] The Lewis-Sumner form of this condition is considered a rare disease with only 50 cases reported up to 2004 ...
Electromyographic studies and nerve conduction studies show normal motor conduction velocity and latency with decreased amplitude of compound muscle action potentials. Pathologically, it is a noninflammatory axonopathy without demyelination. [3] Antibodies attack the coating of the motor neurons without causing inflammation or loss of myelin ...
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
List of medical symptoms. Medical symptoms refer to the manifestations or indications of a disease or condition, perceived and complained about by the patient. [1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals.
The average lifespan after the onset of symptoms in patients with MSA is 6–10 years. [4] Approximately 60% of patients require a wheelchair within five years of onset of the motor symptoms, and few patients survive beyond 12 years. [4] The disease progresses without remission at a variable rate.
