Psychiatry is the medical specialty
concerned with the study of mental disorders and
the diagnosis, management, treatment, and prevention
of mental disorders.
Psychiatry is not to be confused with psychology
- which is the scientific but non-medical
study of the mind, incl. behaviour and mental processes.
Both of these terms are derived from the prefix
psych- which refers to the mind or, more accurately,
to the "psyche" i.e. the "mind or
the soul; the mental as opposed to the physical
aspects of a person".

consider "likely to commit" a crime -
even if the individual has not actually done so,
or even threatened to do so.
