Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

715
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Psychosis: Goals of Pharmacotherapy

646
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Positive Symptoms Schizophrenia: Hallucinations and Delusions

825
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Psychological and Sociocultural Causes of Schizophrenia

736
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Introduction to Stress and Lifestyle

720
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.3K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Summary

People with serious mental illness (SMI) who experience psychosis can achieve posttraumatic growth (PTG). This growth is facilitated by meaning-making and coping self-efficacy, despite challenges from psychotic symptoms.

Area of Science:

  • Psychiatry
  • Psychology
  • Trauma Studies

Background:

  • High trauma exposure rates are documented in individuals with serious mental illness (SMI).
  • Psychosis and mental illness experiences can be traumatic, potentially leading to posttraumatic stress disorder (PTSD) or posttraumatic growth (PTG).
  • Limited research exists on PTG in individuals who have experienced psychosis.

Purpose of the Study:

  • To investigate the relationship between psychosis and posttraumatic growth (PTG).
  • To identify potential mediators of PTG in individuals with psychosis.
  • To explore the impact of psychotic and negative symptoms on PTG.

Main Methods:

  • 121 participants with SMI who experienced psychosis were recruited from community mental health centers.
  • Participants completed trauma and psychiatric questionnaires.
  • Statistical analyses were used to examine relationships between variables.

Main Results:

  • High levels of trauma exposure were prevalent in the sample.
  • Posttraumatic growth (PTG) was observed in individuals with psychosis.
  • Meaning-making and coping self-efficacy (CSE) significantly mediated the relationship between psychosis and PTG.
  • Psychotic symptoms hindered meaning-making, CSE, and PTG, while negative symptoms were associated with PTG through mediation.

Conclusions:

  • Preliminary evidence suggests meaning-making and CSE can mediate PTG in highly traumatized individuals with SMI and psychosis.
  • Findings highlight the potential role of meaning-making and CSE in fostering PTG within this population.
  • The results have implications for both research and clinical practice in psychiatric rehabilitation.
