for this you will need a second or even a 3rd opinion ASAP, if your son has the classic symptoms of this disease he will need immediate care.

Aspergers is not a disease, it is a disorder, or even, more specifically, a syndrome.
It is possible that a child exhibits signs of Aspergers, although 4 is a young age. Typically, young kids are given a diagnosis of Pervasive Development Disorder, because the kids seems "spectrum-y" but they can't pin down a specific diagnosis. Although, if the child exhibits superior intellectual ability, or other traits which are commonly found in Aspies (hyperlexia, for instance) then one could very possibly say that a child is showing signs of Aspergers, even if a diagnosis of AS can't be quite ascertained yet.
Autism spectrum kids are being diagnosed earlier, and more accurately. If the person is qualified and capable of an accurate diagnosis, then it's not unheard of to see fairly obvious signs as young as 4.
As far as immediate care, yes, Aspies do need help beginning as young as possible. Although, getting the wrong help can be more harm than help. I have Aspergers, so does my son, and I am an Aspergers Specialist, and I help (mostly) parents. I have found that when parents understand that Aspergers doesn't need to be "fixed", rather "managed" and guided, they see that really the parents play the largest part in the success of the child, over any single other thing.

Down syndrome is generally the preferred spelling, although Down's syndrome is sometimes used in American sources.

Probably, but it has only recently been named as such and clearly defined. Improved: Noone really knows when Aspergers' Syndrome was FIRST thought out, but the first researcher to define it, has since then made the case. You never know, back when the cavemans were around, Aspergers' syndrome could've had some effect.
Yes, 'tourettes' is correct.--- Not if you refer to the syndrome. Then it is spelled Tourette's
No, Williams syndrome is not life threatening but can be if not treated with the correct medical care
The correct spelling of the autoimmune disease includes the capitalization of the proper name and the umlaut "ö", as Sjögren's syndrome. However, common English use has the normal letter "o", as Sjogren's syndrome.
