Central nervous system fatigue, or central fatigue, is a form of fatigue that is associated with changes in the synaptic concentration of neurotransmitters within the central nervous system (CNS; including the brain and spinal cord) which affects exercise performance and muscle function and cannot be explained by peripheral factors that affect muscle function.
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.
Management of ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) focuses on symptoms management, as no treatments that address the root cause of the illness are available. [1]: 29 Pacing, or regulating one's activities to avoid triggering worse symptoms, is the most common management strategy for post-exertional malaise. Clinical ...
ME/CFS causes debilitating fatigue, sleep problems, and post-exertional malaise (PEM, overall symptoms getting worse after mild activity). In addition, cognitive issues, orthostatic intolerance (dizziness or nausea when upright) or other physical symptoms may be present (see also § Diagnostic criteria ).
Neuromyelitis optica (NMO) is a particular disease within the NMOSD spectrum. It is characterised by optic neuritis and longitudinally extensive myelitis. In more than 80% of NMO cases, the cause is immunoglobulin G autoantibodies to aquaporin 4 , the most abundant water channel protein in the central nervous system. [5] [1] [4]
The central component of fatigue is triggered by an increase of the level of serotonin in the central nervous system. [134] During motor activity, serotonin released in synapses that contact motor neurons promotes muscle contraction. [135] During high level of motor activity, the amount of serotonin released increases and a spillover occurs.
One of those things it activates is the sympathetic nervous system, resulting in symptoms like chills, sweating, heart palpitations, and blurred vision. Your primary care doctor can check your ...
