People with 'late-life schizophrenia'
include two distinct groups:
1. Those who developed schizophrenia early
in life and are now middle-aged or elderly. As growing numbers of individuals
with schizophrenia reach older age, there will be an increasing demand
on the mental health system in Australia to accommodate the complex
psychiatric, medial and social needs of this population. There is limited
data about the course of schizophrenia in later life. What has been
observed, however, is that the rate and frequency of hospitalisation
diminishes as patients grow older. Additionally, ageing among patients
with schizophrenia tends to result in a diminution of positive symptoms
and therefore a reduced need for rehospitalisation for acute episodes
(Auslander & Jeste 2002); and
2. Those with 'late-onset schizophrenia',
who developed the symptoms of schizophrenia after the age of 45 years.
Women tend to develop schizophrenia at a later age than men (Castle
& McGrath 2000; American Psychiatric
Association 2002) and symptoms are more likely to include paranoid
delusions and hallucinations and less likely to include disorganised
and negative symptoms (Auslander & Jeste 2002).Individuals in this
older group have often experienced a better occupational history and
have more often been married. Family studies seem to indicate that late-onset
schizophrenia is less inheritable than early-onset schizophrenia (Jeste
et al. 1995).
Issues for people with late-life schizophrenia
Differing
medication requirements
Research indicates that antipsychotic medications are often effective
for people with late-life schizophrenia and as a result, they require
less medication. Older people, particularly those over the age of 70,
no longer metabolise medication well and are therefore more susceptible
to side effects (Salzman & Tune 2001). Extrapyramidal side effects
are of particular concern in older people as they often experience these
effects more severely and the anti-cholinergic drugs used to counteract
these symptoms are not as effective in this population (Sciolla &
Jeste 1998). Furthermore, polypharmacy (the use of more than one medication)
needs to be administered very carefully, if at all, in older people
because of their increased sensitivity to the effects of medication.
Comorbid medical problems
The development of comorbid medical problems (that is having two or
more medical conditions) is common in elderly people, and greatly complicates
the effectiveness of diagnosing, treating and coping with schizophrenia
(Auslander & Jeste 2002).
Interaction between
normal ageing deficits and schizophrenia
People with late-life schizophrenia can have cognitive deficits associated
with both schizophrenia and normal ageing (for example, slowed processing
and increased distractibility) that may exceed the deficits seen in
either state alone (McDowd et al. 1993).
Relative loss of family
support
Many people with schizophrenia live with or gain support from their
family. While this type of support may still be available if the person
has had their own family, if the person's family of origin were the
only caregivers, this type of family support can be lost to the older
person with schizophrenia
Problems in the
delivery of and access to services
Despite the improvements in the mental health system in New South Wales
since the launch of the Burdekin Report in 1993, there are still many
problems associated with delivery and access to services and resources
for older people with a mental illness. These include (but are not limited
to):
-
lack of a specialised
treatment service for older people with a psychiatric illness (general
adult psychiatric services may not have adequate resources to care
for the specific needs of older clients, while services for elderly
people in general may not have the resources to address mental illness);
-
difficulty in finding
appropriate accommodation (People with late-life schizophrenia may
be placed in inappropriate settings because of a general lack of hospital
and residential beds for elderly people; the inability of psychiatric
facilities to deal with the chronic physical ailments experienced
by the elderly;
-
the inability of nursing
hostels and homes to deal with psychiatric problems);
-
decreased access to services
(physical problems often confine elderly people to their place of
abode; home visits by mental health professionals are rare, so many
elderly people simply do not have access to the services they require);
-
rights may be denied
(older people with a mental illness, especially those with a serious
mental illness such as late-life schizophrenia, and their relatives
are often not fully informed of their rights or are not given the
opportunity to exercise their rights; and
-
discrimination in health
services (elderly people are more likely to receive drug treatment
without being offered other treatment options; they are often given
lowest priority in all mental health services and inappropriate treatment
is often administered because of failure to recognise age-related
complications).
The recent consultation paper on the National
Mental Health Plan 2003-2008, lists "continuity of care across
the lifespan' as one of its priority areas. It states that Australia's
ageing population will require the enhancement of service provision
for this part of the lifespan and suggests the following action: "Ensure
that mental health care is responsive to the diverse needs of consumers
across the lifespan and that treatment approaches are appropriate to
the needs of different lifespan groups, particularly children, youth
and older adults" (p 15).
