The growth retardation has been reported, but not established in
controlled studies as being due to the Ritalin. Since the brains
are already different in hyperactive children the Ritalin may not
be the cause of the growth retardation (which is not severe). The
mechanisms could be several: for weight retardation, it is clear
that sympathomimetic amines suppress appetite. The kids are hardly
emaciated, however. Since dopaminergic neurons play a large role
in hypothalamic function, they could easily exert effects on hormones
leading to growth retardation. So I agree the Ritalin is a plausible
cause of any growth effects, but it should still be established.
However, the chemical and hormonal changes that can influence growth
would not normally be expected to cause permanent changes in the nervous
system. It is far easier to effect permanent changes to bone (determiner
of height) than brain by hormonal means at the age we are talking about.
A bit too much sex hormone will do it, for example, or other steroids.
To change brain, the hormone must operate on a fetus, or possibly very
young infant, according to our present knowledge.
While losing an inch off your final {*filter*} height might not be a good
thing at all (especially if you are short anyhow), it is hardly
incalculable, and might be better than not getting an education.
