When symptomatic, they can cause pain and myelopathy by intra-spinal bleeding, bony expansion or extra-osseous extension into surround soft tissue or the posterior neural elements. [4] [6] [7] [8] Highly vascular (cavernous type) hemangiomas can produce neurologic deficits without prominent evidence of spinal cord compression. The deficits in ...
The books lists ICD-O codes, CNS WHO grades and describes epidemiological, clinical, macroscopic and histopathological features, among others. [2] The following is a simplified (deprecated) version of the fifth edition.
PED differs from two closely related disorders, for example paroxysmal kinesogenic dyskinesia (PKD) and paroxysmal nonkinesigenic dyskinesia (PNKD), based on what brings on the symptoms, namely prolonged exercise, such as brisk walking or running for at least 10 minutes. This is in contrast to PKD where the symptoms are brought about by sudden ...
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system. Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis , and hyperthermia . [ 1 ]
Cerebral cavernous malformation (CCM) is a cavernous hemangioma that arises in the central nervous system.It can be considered to be a variant of hemangioma, and is characterized by grossly large dilated blood vessels and large vascular channels, less well circumscribed, and more involved with deep structures, with a single layer of endothelium and an absence of neuronal tissue within the lesions.
The major meta-categories is Category:Neurological disorders by disease category. A disorder can be categorized in both systems simultaneously (for example, glioma under "Nervous system neoplasia" AND "Brain disorders"). Please sort articles into these sub-categories and avoid categorizing them simply with the parent category Neurological ...
Paroxysmal attacks in various disorders have been reported extensively, and ephaptic coupling of demyelinated nerves has been presumed as one of the underlying mechanisms of this phenomenon. This is supported by the presence of these attacks in multiple sclerosis and tabes dorsalis, which both involve demyelination of spinal cord neurons.
Paroxysmal symptoms are generally associated with hemiplegic attacks and may occur suddenly with hemiplegia or on their own. Paroxysmal symptoms may last for variable amounts of time. Non-paroxysmal symptoms tend to be side effects of AHC which are present at all times, not just during episodes or attacks.
