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. [9]
The central nervous system (CNS) controls most of the functions of the body and mind. It comprises the brain, spinal cord and the nerve fibers that branch off to all parts of the body. The CNS viral diseases are caused by viruses that attack the CNS. Existing and emerging viral CNS infections are major sources of human morbidity and mortality.
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.

The Canadian Consensus Criteria require "post exertional malaise and/or [post exertional] fatigue" instead. [20] [21] [22] [18] [23] On the other hand, the older Oxford Criteria lack any mention of PEM, [24] and the Fukuda Criteria consider it optional. Depending on the definition of ME/CFS used, PEM is present in 60 to 100% of ME/CFS patients. [6]
The brain and the spinal cord are the essential components of the central nervous system and it is responsible for the integration of the signals received from the afferent nerves and initiates action. The nerve cells, known as neurons, carry impulses throughout the body and the nerve impulses are carried along the axon.
Brain degeneration also causes central nervous system diseases (i.e. Alzheimer's, Lewy body dementia, Parkinson's, and Huntington's diseases). Studies have shown that obese people may have severe degeneration in the brain [dubious – discuss] due to loss of tissue affecting cognition. [5] [citation needed]
Many different treatment options have been investigated and assessed scientifically. Since exhaustion disorder results in a long-lasting and severe loss of function, usually brought on by work-related stress, time until "return to work" is considered the most important end-point when evaluating the effectiveness of various treatments.
