A Case Study on Mental and Behavioural Disorders Due to Multiple Drug Use and Use of Other Psychoactive Substances (Icd F19)

Psychosis is associated with schizophrenia, which is primarily associated with severe impairments. And it has an impact on how other aspects of our lives, including work, family, friends, and education, operate (WHO, 2022). A person's behavior and brain are both affected by substance use disorder. It results in an inability to manage the use of a drug or medication, whether it is legal or illicit. The patient, who was diagnosed with a substance use disorder similar to schizophrenia, was the subject of this qualitative investigation. This study adopted a single-case study design. The data were collected by using a mental status examination questionnaire, and the data were analyzed by content analysis. The study participant was a 22-year-old male who has been educated in logistics management and is self-employed. The participant was an inpatient at a private mental health center. This study found that mental and behavioural disorders due to multiple drug use or other psychoactive substances can be managed through cognitive-behavioural therapy, aversion therapy, family therapy, outpatient rehabilitation, inpatient rehabilitation, and pharmacotherapy. This study also provides an insight into how schizophrenia compares to substance use disorder in terms of symptoms, causal factors, and management plans.
