There are many social, environmental and physical causes of developmental disabilities, although for some a definitive cause will never be determined. Common factors causing developmental disabilities include:
* Brain injury or infection before, during or after birth
* Growth or nutrition problems
* Abnormalities of chromosomes and genes
* Babies born long before the expected birth date - also called extreme prematurity
* Poor diet and health care
* Drug misuse during pregnancy, including excessive alcohol intake and smoking.
Developmental disabilities affect between 1 and 2% of the population in most western countries, although many government sources acknowledge that statistics are flawed in this area. The worldwide proportion of people with developmental disabilities is believed to be approximately 1.4% [1]. It is twice as common in males as in females, and some researchers have found that the prevalence of mild developmental disabilities is likely to be higher in areas of poverty and deprivation, and among people of certain ethnicities

I think "mental" is in the eye of the beholder. Or in the eye of someone you have tried to seriously mame or harm. There is no prescribed method of becoming mental. Hopefully you don't feel you've come to that point yet.

It depends on a lot of things, but I think 3 things contribute:
1. stress
2. traumatic experiences
3. lack of ability to cope with things

by being alone all the time, talking to them selfs, locking up them selfs, not talking to people, and not expressing them selfs.
So don't ever do any of those things, and make sure that nobody you know does them either, for your sake!
