What are psychotic disorders?
Psychotic disorders are a group of serious mental health conditions in which a person's thoughts and perceptions significantly deviate from reality, resulting in abnormal behavior. These disorders are characterized by psychotic symptoms, such as delusions, hallucinations, disorganized speech, and grossly disorganized or abnormal motor behavior (American Psychiatric Association, 2013).
In order to meet diagnostic criteria, psychosis must be accompanied by significant distress or impairment to functioning in various aspects of life, including work, relationships, and self-care.
Common symptoms of psychotic disorders
The cluster of symptoms referred to as psychosis can be divided into positive symptoms and negative symptoms. Positive symptoms are experiences or behaviors not typically present in healthy individuals, and are in excess or distortion of normal functioning, including:
- Delusions: Fixed, false beliefs that are not based in reality, such as paranoid delusions (beliefs of being persecuted or conspired against) or bizarre delusions (beliefs that defy natural laws).
- Hallucinations: Sensory experiences without an external stimulus, such as hearing voices, seeing objects or people not present, or experiencing unusual tastes or smells.
- Disorganized speech: Incoherent or nonsensical speech patterns, often jumping from one topic to another in an illogical manner.
- Grossly disorganized or abnormal motor behavior: Bizarre or purposeless movements, such as repetitive gestures or postures.
Negative symptoms, on the other hand, refer to the absence or reduction of certain behaviors or experiences typically present in healthy individuals. These symptoms represent a deficit or loss of normal functions. Common negative symptoms include:
- Diminished emotional expression: A flat affect or lack of emotional responsiveness.
- Avolition: A lack of motivation or ability to initiate and persist in goal-directed activities.
- Alogia: Poverty of speech, characterized by brief and empty responses.
- Anhedonia: An inability to experience pleasure from typically enjoyable activities.
- Social withdrawal: A tendency to isolate oneself and avoid social interactions.
- Poverty of psychomotor activity: reduced motor activity.
