Chronic solvent-induced encephalopathy (CSE) is a condition induced by long-term exposure to organic solvents, often—but not always—in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed.
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 exact pathophysiology, or cause, of the syndrome is still debated but is hypothesized to be related to the disruption of the blood-brain barrier. [12] The syndrome features acute neurological symptoms and reversible subcortical vasogenic edema predominantly involving the parieto-occipital areas on MR imaging. [28]
Other symptoms of a CSF leak include photophobia, dizziness and vertigo, gait disturbances, tinnitus, facial numbness or weakness, visual disturbances, brain fog or difficulties with concentration, neuralgia, fatigue, fluid dripping from the nose or ears, [33] [23]
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 ...
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
High resolution MRI may show hyperenhancement of the blood vessel walls in primary CNS vasculitis and may help to distinguish the lesions form atherosclerotic plaques or reversible cerebral vasoconstriction syndrome which have similar morphology on angiography. MRI usually also shows multiple infarcts, enhancement of the leptomeninges (the ...
Other common causes of chronic organic brain syndrome sometimes listed are the various types of dementia, which result from permanent brain damage due to strokes, [7] Alzheimer's disease, or other damaging causes which are irreversible. Amnestic pertains to amnesia and is the impairment in ability to learn or recall new information, or recall ...
