The word psychosis is used to describe conditions which affect the mind, where there has been some loss of contact with reality.
Symptoms of psychosis include changes in mood, thinking, perception (hallucinations) and behaviour as well as abnormal ideas (delusions).
When someone has psychosis, a diagnosis of a particular psychotic illness is usually given.
When someone is experiencing a psychotic episode for the first time, it is particularly difficult to diagnose the exact type of psychosis, because many of the factors which determine the label remain unclear - often only time and close monitoring will tell.
There are a number of disorders that can present with psychotic symptoms:
Bipolar Disorder ( also known as Manic Depression)
Drug Induced Psychosis
Brief Psychotic Disorder
Schizophrenia - sufferers experience at least 2 (or more) of the following: delusions, hallucinations, disorganised speech, grossly disorganised behaviour - these are known as positive symptoms - plus loss of interest, poor motivation and social withdrawal - these are known as negative symptoms.
These signs and symptoms are associated with a marked reduction in social and occupational functioning.
Depression - sometimes people who suffer from a persistent low mood also experience psychotic symptoms (also called Psychotic Depression)
Bipolar Disorder - sufferers experience mood swings or "highs and lows". Sometimes they can experience psychosis with these mood fluctuations.
Schizoaffective Disorder - sufferers experience a mood disturbance (either 'high' or 'low') with psychotic symptoms, but also experience significant symptoms of psychosis when their mood is normal.
Delusional Disorder - characterised by non - bizarre delusions (ie: plausible beliefs) without other positive symptoms of psychosis.
Substance Induced Psychosis - the psychotic symptoms are judges to be a direct consequence of drug abuse, or exposure to a medication or toxin.
Brief Psychotic Disorder - the psychotic disturbance is brief and lasts more than a day but less than a month.
Antipsychotic - medications that target the chemical imbalance in the brain that causes psychosis. eg. Olanzapine (Zyprexa), Risperidone (Risperdal), Quetiapine (Seroquel), Clozapine (Clozaril)
Antidepressants - medications that treat depression eg. Fluoxetine (Prozac), Citalopram, (Cipramil), Paroxetine (Aropax)
Mood Stabilisers - medications that treat the mood fluctuations associated with Bipolar Disorder eg. Lithium, Sodium Valproate (Epilim), Carbamazepine (Tegretol)
Sometimes these medications are used in combination to treat psychosis.
