A form of mercury poisoning resulting from long term exposure to low doses of mercury. The syndrome of micromercurialism involves complex symptoms of stress, fatigue, memory loss, fine tremors, muscular and reflex insufficiency and low blood pressure, caused by accumulation of mercury in the system. A condition of hyperthermia is accompanied by a series of functional changes under the effects of mercury. The combined simultaneous effect of toxic action, temperature and galvanic response infers a cycle of disintegration and change.
