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 ...
Toxic-metabolic encephalopathy: A catch-all for brain dysfunction caused by infection, organ failure, or intoxication. Transmissible spongiform encephalopathy : A collection of diseases all caused by prions, and characterized by "spongy" brain tissue (riddled with holes), impaired locomotion or coordination, and a 100% mortality rate.
A metabolic encephalopathy develops, and this can progress to coma and death without treatment. [4] Ammonia is only toxic to the brain, other tissues can handle elevated ammonia concentrations without problems. [5] Later onset forms of OTC deficiency can have variable presentations.
Hypoglycemic encephalopathy is often seen in diabetics as a result to accidental overdose with the long-acting sulfonylurea drug group. [12] Brain regions affected by toxic leukoencephalopathy have been seen to be affected by this disease as well; however, hypoglycaemic encephalopathy has been known to involve both white and grey matter ...
Patients presenting as acute and hyperacute liver failure are at greater risk of developing cerebral edema and grade IV encephalopathy. The pathogenesis remains unclear, but is likely to be a consequence of several phenomena. There is a buildup of toxic substances like ammonia, mercaptan, serotonin and tryptophan in the brain.
Other conditions that may present similarly include other causes of high anion gap metabolic acidosis such as diabetic ketoacidosis, toxic alcohol ingestion, and starvation ketosis. [2] Toxic alcohol ingestion includes methanol and ethylene glycol poisoning. [6] Pancreatitis, alcoholic hepatitis, and gastritis may also result in similar ...
From November 1995 to November 1996 in France, a national survey of pediatric departments for children under 15 years of age with unexplained encephalopathy and a threefold (or greater) increase in serum aminotransferase and/or ammonia led to the identification of nine definite cases of Reye syndrome (0.79 cases per million children). Eight of ...
The acquired demyelinating diseases are classified according to their underlying causes into five groups: noninfectious–inflammatory, infectious–inflammatory, toxic–metabolic, hypoxic–ischemic (vascular problems like Binswanger's disease), and traumatic. [2] This classification is diffuse sometimes.
