Question?: What Is Autism Spectrum Disorder

Mary asks…

What’s the difference between a syndrome and a disorder?

I was thinking about Autism Spectrum *Disorders*, and the way I have been told it is, is that Asperger’s *Syndrome* is a type of ASD. So why is Asperger’s considered to be a syndrome rather than a disorder and why is autism considered a disorder (especially since if anything autistic people are generally “more ordered” than other people are). Just wondering……..:)
Ok, then why autism considered to be a disorder? Autism is mental, not physical.

admin answers:

A syndrome refers to a specific set of recurring symptoms, whereas a disorder is a more general term for a disturbance. You can have a disorder but not display the symptoms, whereas a syndrome *is* the symptoms.

For example, AIDS is a syndrome (hence the S) caused by HIV. You can have the virus, but if you’re not displaying any symptoms, then you don’t have AIDS.

Don’t get too worked up on the difference, though. This is especially true when it comes to autism, considering it can have benefits as well as downsides, and for a lot of people isn’t really a problem. Autism isn’t really a disease so much as it is a difference from the norm, and for some people those differences cause a problem and for others they don’t. That’s why the terminology gets so shaky.

Question?: Ppd Test

Donald asks…

How is the ppd skin test being measured?

My son got a negative x-ray but his PPD tested positive, doctor measured the rash that appeared on his forearm and it says 12mm.

A doctor friend told us the raised/elevated portion should be measured, but in my son’s case, the diameter of the rash was measured and not the elevated portion.

What is the correct way of measuring the rash to say it’s positive?

Forgot to note, he tested positive for Primary Complex TB.

admin answers:

They test it differently – but that stupid test is miss-read so much. The best way to test for TB is a quantiferon blood test. However, they aren’t free.

Good news is he most likely has latent TB if he tested positive to the skin test and has no signs in the chest X-ray. Latent TB is not contagious, has no symptoms, and he will otherwise be 100% normal. Latent TB means he came in contact with the bacteria but his body walled off the attack; did not kill it. That is why he tested positive in the skin test. There is medication to kill the bacteria, but it is a pill, daily, for 9 months.

Something like 1/4 people have latent TB and only 1/10 turn into active TB from there. People who have latent TB are at a higher risk than people who don’t, but still very low.

Latent TB isn’t dangerous unless the patient has some kind of disorder that lowers their immune system, such as the HIV infection.

But back to your question – people read the blister, not the rash.
