Obtundation
Template:Short description Template:Infobox medical condition (new)
Obtundation is mild to moderate alertness reduction (altered level of consciousness) with decreased interest in the environment and slower than normal reactivity to stimulation.Script error: No such module "Unsubst". It is distinguished from the much stronger states of unresponsiveness of stupor and coma. Obtundation typically occurs as a result of a medical condition or trauma.[1]
There is a wide range of potential causes including head injury, interruption of blood circulation, impaired oxygenation or carbon dioxide toxicity (hypercapnia); central nervous system (CNS) infections, drug intoxication or withdrawal, post-seizure state, hypothermia, and metabolic derangements such as hypoglycemia, hyponatremia, and hypercalcaemic crisis.[2]
Symptoms include delayed reaction time, lessened interest in the environment, very short attention span, and excessive sleeping.[3]
The root word, obtund, means "dulled or less sharp" (cf. obtuse angle).
