Methamphetamine-induced Psychosis

This prospective cohort study aims to investigate factors associated with psychiatric symptom severity in participants diagnosed with methamphetamine-induced psychotic disorder (MP) with and without lifetime cannabis use (LCU). Participants hospitalized at Elazığ Mental Health and Diseases Hospital who meet Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) criteria for MP will be included. Participants will be divided into two groups based on the presence or absence of LCU. Psychiatric symptoms and clinical characteristics will be assessed weekly during an eight-week inpatient follow-up period using standardized psychometric instruments. The study aims to determine whether LCU influences the course and severity of psychiatric symptoms in MP and to identify environmental, individual, and familial factors associated with symptom progression.

This prospective cohort study aims to examine and compare electrocardiogram (ECG) parameters in subjects diagnosed with Methamphetamine Use Disorder (MUD) and Methamphetamine-Induced Psychotic Disorder (MP) during inpatient psychiatric treatment. ECG findings at hospital admission and during remission prior to discharge will be evaluated and compared between groups. The study also aims to determine whether methamphetamine-induced psychosis is associated with greater ECG abnormalities and increased cardiac risk compared to methamphetamine use without psychosis.

This longitudinal observational study aimed to investigate environmental, familial, and individual factors associated with psychiatric symptom severity in participants diagnosed with methamphetamine-induced psychotic disorder (MP). Participants diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5-TR) criteria was followed/will be followed prospectively for one year. Sociodemographic characteristics, treatment adherence, perceived social support, addiction-related clinical variables, insight levels, and psychotic symptoms was assessed/will be assessed monthly using standardized psychometric instruments. The study aimed to identify predictors associated with relapse-remission patterns and changes in psychiatric symptoms over a one-year follow-up period.

This cross-sectional observational case-control study aimed to examined serum levels of leucine-rich repeat and fibronectin type III domain-containing protein 5 (LRFN5) and olfactomedin-4 (OLFM4) levels in methamphetamine use disorder (MUD), methamphetamine-induced psychotic disorder (MP), and healthy control (HC) groups. The study also aimed to assessed systemic inflammation using the Aggregate Index of Systemic Inflammation (AISI) and examined associations between biomarkers and clinical symptom severity, including Insight Assessment Scale (IAS) and Positive and Negative Syndrome Scale (PANSS) scores.

This hospital-based observational study employed prospective follow up study will be conducted in sohag university hospital clinics aiming to ensure cases presented with psychosis in two phases to differentiate into 2 groups (a case of schizophrenia or a case of METH induced psychosis) Phases-1 includes: 1. Screening and Consent: All consecutive patients meeting initial criteria for psychosis were informed about the study. After explaining the procedures, written informed consent was obtained. 2. Diagnostic Interview: Each participant underwent a SCID-5 interview to confirm DSM-5 diagnoses. The SCID modules relevant to psychotic disorders were used (including the psychotic and substance-use modules). Information from patient self-report and available medical records was incorporated into the diagnostic assessment. 3. Symptom Rating: Following diagnosis, a trained clinician conducted the PANSS interview. This involved structured questions about symptoms over the past week, supplemented by clinical observation. Each PANSS item was scored on a 1-7 scale according to established guidelines. The positive- and negative-symptom subscale scores were recorded for analysis. 4. Clinical Data: A semi-structured form was used to record demographic data, psychiatric history (age at onset, duration of illness), medication history, and details of methamphetamine use (duration, frequency, last use and drug screening). Data were entered into a secure study database. Phase 2 includes: Follow up visit after 3 months to obtain : Positive and Negative Syndrome Scale (PANSS) Drug screening Time of recovery, response to treatment, relapse , job dysfunction duration. Aim of the study: The study aims to compare between: 1. Clinical profile-risk factors-of schizophrenia vs methamphetamine induced psychosis in sohag governorate 2. Compare between response to treatment * the need of hospitalization and its duration * time of recovery * job dysfunction duration
