What Are the Types of Psychosis? When Someone Has a Psychosis, a Diagnosis of a Particular Psychotic Illness Is Usually Given

What are the types of Psychosis? When someone has a psychosis, a diagnosis of a particular psychotic illness is usually given. A diagnosis means identification of an illness by a person’s symptoms and the diagnosis will depend on what brought on the illness and how long the symptoms last. Many psychotic symptoms like hallucinations and delusions are common to all psychoses. This means that the boundaries between the different types of psychosis are blurred and it is often difficult to make a decision. The most common conditions in which psychosis occur are: • Brief Psychotic Disorder - This is a psychosis that lasts less than one week that is a reaction to a severe stress. It can involve quite severe symptoms but recovery is quick. • Organic Psychosis - This type of psychosis can be clearly related to a physical problem that disrupts brain functioning and is caused by illness or head injury. • Substance-Induced Psychosis - This type of psychosis is associated with alcohol or drug abuse or withdrawal. It is usually brief with psychotic symptoms resolving as the effects of the substances wear off, although in some cases longer lasting psychotic illness seems to begin with substance induced psychosis. • • Bipolar Disorder (or Manic-Depression) - Bipolar Disorder is a mood disorder which may or may not be accompanied by psychotic symptoms. Prominent symptoms are extremes of mood both highs (mania) and lows (depression). Psychotic symptoms when present fit in with the person’s mood. • • Major Depressive Episode with Psychotic Features (or Psychotic Depression) - This diagnosis is made when there is depression with psychotic symptoms but without mania (high). • • Schizophrenia - This type of psychosis includes hallucinations, delusions and changes in behaviour, feelings and thinking that have been continuing for a period of at least six months. • Schizophreniform Disorder - A psychosis like Schizophrenia however the symptoms last more than one month and less than six months. • • Schizoaffective Disorder - This diagnosis is made when the person has symptoms of both a mood disorder (depression or mania) and psychosis. .

Brief Psychotic Disorder Diagnostic Criteria 298.8 (F23)
Brief Psychotic Disorder Diagnostic Criteria 298.8 (F23) A. Presence of one (or more) of the following symptoms. At least one of these must be (1), (2), or (3): 1. Delusions. 2. Hallucinations. 3. Disorganized speech (e.g., frequent derailment or incoherence). 4. Grossly disorganized or catatonic behavior. Note: Do not include a symptom if it is a culturally sanctioned response. B. Duration of an episode of the disturbance is at least 1 day but less than 1 month, with eventual full return to premorbid level of functioning. C. The disturbance is not better explained by major depressive or bipolar disorder with psychotic features or another psychotic disorder such as schizophrenia or catatonia, and is not attributable to the physiological effects of a substance (e.g., a drug of abuse, a medication) or another medical condition. Specify if: With marked stressor(s) (brief reactive psychosis): If symptoms occur in response to events that, singly or together, would be markedly stressful to almost anyone in similar circumstances in the individual’s culture. Without marited stressor(s): If symptoms do not occur in response to events that, singly or together, would be markedly stressful to almost anyone in similar circumstances in the individual’s culture. With postpartum onset: If onset is during pregnancy or within 4 weeks postpartum. Specify if: With catatonia (refer to the criteria for catatonia associated with another mental disorder, pp. 119-120, for definition) Coding note: Use additional code 293.89 (F06.1) catatonia associated with brief psychotic disorder to indicate the presence of the comorbid catatonia. Specify current severity: Severity is rated by a quantitative assessment of the primary symptoms of psychosis, including delusions, hallucinations, disorganized speech, abnormal psychomotor behavior, and negative symptoms.

Appropriate Use of Antipsychotics in Dementia Is Also an Issue in the Community, in Supportive Living Facilities and in Acute Care
1 Antipsychotics are a class of medications developed in the 1950’s to treat the symptoms of schizophrenia, enabling people with this illness to live in the community Typical antipsychotics such as Haldol and Largactil came to be used for some of the symptoms and behaviours of dementia. Concern developed regarding side-effects such as tardive dyskinesia (a movement disorder that can be permanent). When atypical antipsychotics were introduced in the 1990’s, it was believed they had fewer side-effects. Over time, we learned they don’t have fewer side-effects - just different side-effect profiles. As the use of antipsychotics grows, so do reports of harm. Aripiprazole is the newest atypical antipsychotic and is considerably more expensive than the generic second-generation atypical antipsychotics. Utilization and popularity of this newest antipsychotic is growing, unfortunately without outcome related evidence. It’s expected that reports of harm will also accumulate with aripiprazole. There is a recent tendency to revert back to Haldol and other typical antipsychotics, which are NOT safer, in light of a growing number of Health Canada alerts regarding atypical antipsychotics. 2 It’s important to emphasize this is not an initiative to eliminate antipsychotics but to use antipsychotics appropriately. People with chronic mental health conditions such as schizophrenia or Huntington’s Chorea likely require long term use, though the dosage may need to be reassessed as they age. Antipsychotics may be used as adjunctive treatment in refractory depression, and for other chronic mental health conditions. Antipsychotics may also be helpful in distressing psychosis - Dementia itself may cause a distressing psychosis –in this case, antipsychotics are a temporary treatment, as needs change over time with disease progression.
