In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue.

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.
The term post-infectious fatigue syndrome was initially proposed as a subset of "chronic fatigue syndrome" with a documented triggering infection, but might also be used as a synonym of ME/CFS or as a broader set of fatigue conditions after infection. [26] Many individuals with ME/CFS object to the term chronic fatigue syndrome. They consider ...
The fatigue must have lasted for 6 months or longer, and be present at least 50% of the time; Other symptoms are possible, such as muscle pain, mood problems, or sleep disturbance; Conditions known to cause severe fatigue and some mental conditions exclude a diagnosis.

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 ...
The symptoms vary widely, as do the treatments. Central nervous system tumors are the most common forms of pediatric cancer. Brain tumors are the most frequent and have the highest mortality. [4] Some disorders, such as substance addiction, autism, and ADHD may be regarded as CNS disorders, though the classifications are not without dispute.
Muscle cramps, dizziness, fatigue, nausea, and vomiting might happen, as well. When the weather is warm, you might get dehydrated or end up with heat exhaustion, which triggers chills.
Focal neurologic signs, also known as focal neurological deficits or focal CNS signs, are impairments of nerve, spinal cord, or brain function that affects a specific region of the body, e.g. weakness in the left arm, the right leg, paresis, or plegia. [citation needed]
