Identifying Psychosis
Terence Watts
It is sometimes quite difficult to be certain
exactly where the dividing line between neurosis and psychosis actually is,
and some psychotically ill individuals can be very deceptive, often appearing
to be quite intelligent and even superficially charming. It is as wrong to
assume that you can recognise an individual with this illness by the appearance
or demeanour as it is to believe that they are always dangerous.
The term 'Schizophrenia' - probably the most
common form of psychosis - actually refers to not one, but a group of psychotic
illnesses which often start in adolescence or young adulthood. There tends
to be 'attacks' with gaps in between, typically starting at about 15 years
old; between attacks the sufferer can seem quite normal, though the frequency
of attacks will tend to increase - slowly if their environment is good (stable
home, low excitation levels, low 'life-difficulties', supportive relatives,
etc.) but faster if not (Homeless, frustration, angry/nagging relatives or
companions, stress of any sort).
There can be an inherited predisposition with
some individuals - the disorder definitely runs in families. Children who
have one schizophrenic parent have TEN TIMES the chance of developing the
disorder than if their parent had been 'normal'. During your information gathering,
you should always enquire as to the emotional and psychological health of
your client's parents. If they tell you that one of them was excessively anything
that could be taken to indicate schizophrenia, then explore your client's
psyche that much more carefully.
The advice to the GP about diagnosing Schizophrenia
is that any one of the symptoms from the first group, below, or two from the
second group should have been present most of the time for a period of no
less than one month.
Group One
- Thought echo,
- withdrawal,
- insertion or broadcasting
- Delusions of control or passivity
- Delusional perception
- Third person hallucinatory voices
- Persistent bizarre delusions
Group Two
- Persistent hallucinations in any modality
- Thought blocking and disorder
- Neologisms Catatonia Apathy,
- poverty of speech or thought
- Blunting of affect and social withdrawal
The 1992 classification of schizophrenia lists
five types: paranoid, hebephrenic, catatonic, residual and simple, with Paranoid
Schizophrenia being the most common.
There are around 10,000 new cases of schizophrenia
diagnosed every year; the risk of developing it during the course of a lifetime
is reported to be in the region of 1 in 100. In its full form it is very obvious
but there is a borderline 'grey' area into which many neurotics fit just as
easily as potential psychotics, and this is where we have to be careful.
This bears repetition because it is so important:
you simply cannot tell whether or not an individual is schizophrenic from
the appearance alone; the psychotic often has a very high IQ and will not
infrequently be a 'high-flier' of some sort in commerce or industry, or maybe
running - or claiming to run - a hugely successful business or two. That,
in itself, veers away from the norm and should prompt you to find out more.
Obviously, not all successful people are psychotic, nor are all psychotic
people successful, but the circumstance of a genuinely intelligent, successful,
smartly presented and superficially charming psychotic is far from unknown.
