Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]
Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken. The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.
Peripheral neuropathy, often shortened to neuropathy, refers to damage or disease affecting the nerves. [1] Damage to nerves may impair sensation, movement, gland function, and/or organ function depending on which nerve fibers are affected. Neuropathies affecting motor, sensory, or autonomic nerve fibers result in different symptoms. More than ...
The signs and symptoms of Peripheral mononeuropathy and neuropathy vary as a result of the types of individual and/or nerve areas affected. There are three types of nerve damage, including: "motor nerve damage, sensory nerve damage, and autonomic nerve damage". [2]
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 ...
In 1982 Lewis et al. reported a group of patients with a chronic asymmetrical sensorimotor neuropathy mostly affecting the arms with multifocal involvement of peripheral nerves. [47] Also in 1982 Dyck et al reported a response to prednisolone to a condition they referred to as chronic inflammatory demyelinating polyradiculoneuropathy. [ 48 ]
Focal demyelination is a hallmark of entrapment neuropathies, which are often characterized by nerve conduction slowing or block. [34] The initial changes are a break-down in the blood nerve barrier, followed by sub-perineurial edema and fibrosis ; localized, then diffuse, demyelination occurs, and finally Wallerian degeneration .
Globally diabetic neuropathy affects approximately 132 million people as of 2010 (1.9% of the population). [41] Diabetes is the leading known cause of neuropathy in developed countries, and neuropathy is the most common complication and greatest source of morbidity and mortality in diabetes.
