autistic children and those with "other developmental disorders"

Autistic children are going to be given "functional connectivity 'magnetic resonance imaging' (MRI)'s, along with children with "some other developmental disorders." What are the "other developmental disorders"? I am uncertain.

"Certain connections in the brain get stronger over time; "others are pruned away", according to researchers (psychologist researchers).
A "brain age scale" has been created from 'magnetic resonance imaging' (MRI) brain scans of two hundred "normal people" with "typical" brain connections.
The research is said to show connections in the "brains of children with autism are [a bit] weaker than in typical children", a psychologist researcher said.
These scans will be used to test "brain networks" in infants "to spot signs of trouble".

I think that these will probably be used more in infants. I think that if they are used after medicines, a good idea is to give a 'magnetic resonance imaging' (MRI) before medicines.

As of now, 'magnetic resonance imaging' (MRI) has been used after medicines, so there are not comparisons of the brains of one with "schizophrenia" before medicines. The medicines change bodies, blood, brains. How do we know what the brain of one with "schizophrenia" looks like, really, since there are only 'magnetic resonance imaging' (MRI)'s after the medicines are given. The medicines change brains, blood, and bodies. Can the 'magnetic resonance imaging' (MRI)'s be given before the medicines are given, to show that one has "autism", "schizophrenia", "manic depression (bipolar)", and "other developmental disorders"?

This makes more sense, I beleive, because after the medicines given to those who are not given 'magnetic resonance imaging' (MRI)'s there is not any way to tell if there was a person with "autism", "schizophrenia", "manic depression (bipolar)", and "other developmental disorders" (including "depression" (unipolar), "schizoaffective disorder", and, what others?).
Once the medicines are given, the 'magnetic resonance imaging' (MRI)'s show the damage done by medicine; certainly, there are changes in blood, bodies, and brains.

When a 'magnetic resonance imaging' (MRI) shows that a person has "autism", "schizophrenia", "manic depression (bipolar)" or "other developmental disorders", is it showing the effect and/or impact of the medicines on the brains, bodies, and blood of those already given medicine? I think so.

Often, certainly sometimes, a person has been said to have "schizophrenia" only after death and a lifetime (usually from the "tens" (10-19)) of medicines. How can we know that the brain studies show "schizophrenia" when the medicines cause so many changes in bodies, brains, and blood.

Remember the identical twin studies. Even understanding that the medicines cause many brain, body, and blood changes: less than 48% of identical twins both have "schizophrenia". I think, genes in identical twins are mainly or mostly identical. How can "schizophrenia" be a genetic disorder if this is true? Less than 48% of identical twins both have "schizophrenia".

Why don't we give 'magnetic resonance imaging' (MRI)'s to children, "tens", and adults before they are put down and "put away"?

[No "this past week" for this past week.]

note: the word "schizophrenia" and the 'disease' "schizophrenia are only one hundred years old. the word "teenager" is less than one hundred years old (i call them "tens".)
