While this list has some good things on it, it is a bit too general for my tastes. 1. True. 2. No, but it definitely can be exasperated by nerves. 3. True. Stutterers can learn behaviors that mimic low intelligence as a defense mechanism, tho. 4. Short answer: Yes, with an “if.” Long answer: No, with a “but.” It can be hereditary, in fact it often is, and it can be learned (as in "The Monster Study"), but it is very uncommon for a parent to actually cause it. 5. I've seen no scientific evidence either way on this. Comment if you have any. 6. This is a touchy one. At what fluency is someone "cured?" Is it at 100% fluent speech, or is it at the point where a person is no longer effected by their stutter? Is an alcoholic ever cured? Is that even a valid comparison? Given that some treatments work great for some people and not at all for others, I'd say some stutters can be cured, but it is very rare. This is leaving out the 50% or so that "grow out of it," of course. 7. True. Its also "stuttering" in Asia as far as I know. 8. Stuttering can be caused by a trauma, either physical or emotional. Both are rare, but it does happen. Stuttering can be caused by a TBI or stroke, for example. Something identical to stuttering can also be caused by Parkinson's. It can be caused by emotional or mental trauma as well, but it is rare.
