A quasi-psychotic episode is a psychopathological condition that can occur in people with various mental disorders, including schizotypal disorder. During a quasi-psychotic episode, a person may experience delusions, paranoia, and disorientation in space and time. During a quasi-psychotic episode, patients may experience the same symptoms as during a psychotic episode, but with less severity. This is often associated with stress, insomnia, and drug use. The duration of a quasi-psychotic episode can vary greatly and depends on what type of disorder the person has, as well as how quickly help was provided and treatment started. In the case of schizotypal disorder, quasi-psychotic episodes can last from several hours to several days or weeks. Quasi-psychotic episodes can occur in various diseases, including organic and personality disorders, as well as neurological diseases. Organic disorders: Parkinson's disease, Alzheimer's disease, vascular dementia, Stroke, head trauma, and other brain disorders may cause quasi-psychotic episodes. This is associated with impaired functioning of the nervous system, which can lead to inadequate perception of the surrounding reality and the appearance of psychotic symptoms [1]. Mental disorders: Quasi-psychotic episodes can be associated with many mental illnesses, including schizophrenia, bipolar disorder, depression, post-traumatic stress disorder (PTSD ) and obsessive-compulsive disorder (OCD) [2]. Neurological diseases: epileptic seizures can also be accompanied by quasi-psychotic episodes [3]. In any case, it is important to pay attention to these episodes and consult a specialist to assess the condition and prescribe the necessary treatment. Treatment may include medication, therapy sessions, and lifestyle changes to reduce stress and increase comfort. Sources: Lauterbach, E. C. (2012).
