Inappropriate laughing/giggling... Yeast or PSEUDOBULBAR AFFECT?

[Guest guest]

I found this very, very intriguing so I wanted to post it here to

see what you all think. A parent that I correspond with on the

ChildrenwithAutism Group posted something very interesting. She

said she was talking on the phone with a friend who has MS when her

autistic child entered the room giggling hysterically. She said to

her friend, " Can you hear him? " She told her friend with MS that her

son can go from crying to laughing hysterically for no apparent

reason. Her friend explained to her that there is a symptom of MS

called Pseudobulbar that is very dimilar to the behavior exhibited

by her son. This mother looked up Psuedobulbar and found the

following:

Affective Release, also called Pseudo-bulbar Affect; a condition in

which episodes of laughing and/or crying occur with no apparent

precipitating event. The person's actual mood may be unrelated to

the emotion being expressed. This condition is thought to be caused

by lessions in the limbic system, a group of brain structures

involved in *emotional feeling or expression*.

What do you guys think of this? I really think this is plausable,

so much so that I asked the Mom if I could spread her story to this

and other groups to see what everyone thought? It really caught my

eye b/c I had just read an abstract stating that the Hep. B and

Influenza vaccines have been implicated as possible triggers for MS

(a crippling disease in which the body attacks the conductive

coating of nerve cells in the brain). I've read several posts from

parents whose children have delayed myelin, so there seem to be

similarities between Autism and Multiple Sclerosis.
