- What is "Laughing Death"
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I don't know how you come up with all the information, but I think
- this one may test you just a bit. It is a disease called "the laughing death"
- and I became aware of it while serving in our Armed Forces. With just this as
- a clue, what can you tell me about this condition?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Obviously, if I couldn't come up with an answer, I just would not
- include your question in the column. Honestly, it has taken a bit of looking
- to find out the information about a disease called "kuru" which only occurs in
- the Fore tribe of the Papua region in eastern New Guinea. The best guess as
- to its cause is that it results from a viral infection by a "slow" or
- retrovirus that causes wide spread changes in the brain, and may have an
- incubation period as long as 30 years. Other theories that cited toxic or
- nutritional factors as the cause seem improbable. It occurs most frequently
- in children and adult women, who suffer involuntary trembling and jerking
- (ataxia) of the leg muscles, incoordination then spreading to the arms,
- slurred speech, incontinence, and finally they are incapable of making sounds
- or swallowing. As a degenerative disease of the central nervous system, it
- causes about 70% of the female deaths in this tribe, and may be due in part to
- the ritual cannibalism practiced by the women and children. There is no known
- cure, and the affliction has never been identified outside of this area,
- although it can be transmitted to chimpanzees. The incidence of the disease
- has declined with the cessation of cannibalistic rituals. The term "laughing
- death" is not commonly used, and possibly refers to the state of dementia that
- may occur shortly before death.
