Schizoaffective disorder

The diagnosis of schizoaffective disorder is given to someone who experiences both symptoms of a mood disorder like depression and symptoms of the type experienced with schizophrenia at the same time, or within days of each other.

 

What is schizoaffective disorder?

 

Schizoaffective disorder is a controversial diagnosis because the symptoms often seem similar to either schizophrenaia or manic depression. Some clinicians do not believe there are sufficient differences to justify a separate diagnosis.

 

The diagnosis is given to someone who experiences symptoms of both a serious mood disorder and schizophrenia at the same time, or within days of each other. Generally, two subtypes of the disorders are recognised:

 

  • bipolar (schizoaffective, manic or mixed type.) Also called schizomania.
  • unipolar (schizoaffective, depressed type).

 

Symptoms usually begin in early adult life, with men tending to show symptoms earlier than women. About one in every 200 people is thought to develop the disorder at some point, and it tends to affect more women than men.

What are the symptoms?

 

Schizoaffective disorder is characterised by the presence of both of the following:

 

  • A serious mood disorder. This may be either bipolar (characterised by extreme swings from depression to elation), or unipolar depression (characterised by a consistently low mood, loss of appetite, sleep disturbance, loss of energy and concentration, despair and/or thoughts of suicide).
  • Psychotic symptoms. These are similar to those experienced in schizophrenia – such as perceptual disturbances (hallucinations – e.g. hearing voices that others can’t hear) and disordered thinking (e.g. delusions - holding unusual beliefs that suggest a person may be out of touch with reality).

 

Because mood disorders (such as manic depression) can sometimes feature psychotic symptoms, a diagnosis of schizoaffective disorder is usually only made if psychotic symptoms persist for at least a fortnight after the mood has stabilised (for example, after a period of mania).

How do people describe their experiences?

“When I am very ill with the schizophrenic aspect of the disorder, I see terrible things such as huge menacing spiders, people with weapons and demons, which all want to attack me. The voices are also terrifying - sometimes I hear Satan’s voice berating me. Depression is a big enemy of mine and I have made some serious attempts on my life. At other times I become very active – not sleeping at all and believing I am invincible – these episodes don’t last long and are usually followed by depression.”

What causes schizoaffective disorder?

 

Research shows that there is a strong genetic component, as the disorder tends to occur in people with a family history of mood disorder or schizophrenia. Otherwise, little is known about the factors in an individual that makes them vulnerable. What is clear is that adverse life events, social stress and excessive use of alcohol or recreational drugs significantly contribute to triggering or precipitating the onset of the disorder and contribute to the risk of future relapses.

What treatments are available?

 

The most successful treatments combine medication, talking therapies and social interventions (such as help making friends). During the acute phase, individuals often need inpatient care e.g. treatment in a hospital. Before or after the acute phase they may need ongoing care in the community e.g. visits to their home from a healthcare worker.

 

Drug therapy usually involves a combination of several different types of medicine. For example, a mood stabiliser (Lithium, Sodium Valporate) together with an anti psychotic (for bipolar individuals) and an antidepressant and an anti psychotic (for unipolar individuals). Rarely, electroconvulsive therapy (ECT) may be suggested as a treatment for severe depression when the individual’s life is at immediate risk, for example when they have stopped eating or drinking.

 

Recommended psychological approaches include individual or group Cognitive Behavioural Therapy (CBT) and when indicated, family therapy. Social interventions include the Social Rehabilitation Model, which aims to assist people with independent living skills, developing social contacts and finding employment.

What is known about the outcome in schizoaffective disorder?

 

The condition is often regarded as less disabling than schizophrenia, although thirty to forty per cent of people will attempt suicide, and one in ten will succeed.

 

The majority of people make a full recovery following each episode. Some people may have only one episode, whilst others will experience recurrences throughout their life, particularly at times of stress.

 

  • People with bi-polar schizoaffective disorder tend to have severe psychotic symptoms and grossly disturbed behaviour but make a rapid and full recovery within weeks.
  • People with uni-polar schizoaffective disorder tend to have less severe psychotic symptoms but these last longer.

What can you do to help yourself?

 

If possible, people with schizoaffective disorder should involve themselves as much as possible in agreeing their care plan, so as to feel they are taking control of the problem. As well as professional interventions, there may also be value in self-help strategies, such as attending support groups and learning relaxation techniques. Taking exercise and eating a balanced diet may also be important.
