Besides from autism, there are many other mental disorders. Some with similar to autism others are very different. And they are in many different categories. I have found two links to wikipedia. One for information on Aphasia, the other is a link to a dictionary of all the mental disorders known (including autism’s).
My special thanks to wikipedia for these link. Hope this gives you a lot of information.
Add since it is two days before Christmas enjoy my favourite Christmas song, that helped inspire me to stay positive during the Holidays. Of course you must know Rudolph the red nose reindeer.
