There is still such a long way to go.

Those drugs which killed so many elderly people can be used on children
and for the rest of their lives. One of those drugs, clozapine, directly
killed 2 people in less than 5 years and has contributed to the
significant reduced life expectancy of the 6,000-7,000 people prescribed
it. These drugs are called "antipsychotics" but they may not be
antipsychotic, i.e. they may not actively stop delusions and
hallucinations which is what the public and patients expect these drugs
to do.

Electro-convulsive therapy is another extreme treatment the patient is
shocked to cause a seizure but has been found to be as effective as sham
ECT (where no current is passed) in the long term. Some people have died
because of this treatment and others have had detrimental side effects.
It has been used on pregnant women and many others but a recent review
of trials shows this treatment to be ineffective.

The Mental Health Act 1983 amendments allow for a person to be
incarcerated without having committed a serious crime but for being at
risk of committing a serious crime, a risk solely determined by a
psychiatrist; they may be hospitalised without treatment nor need for
any treatment to exist so this is little different from imprisonment in
the aspect of loss of liberty, society's greatest punishment which is
only allowed to be applied with the rigour and process of the criminal
justice system.

Of the 6,000 or so completed suicides every year around 20% are by
people diagnosed with schizophrenia; those who don't take their life
still die 20 years younger than the average person.
