Epidemiologic triangle and discuss its application to practice

Differentiating Psychosis-Related Disorders

• Schizophrenia:

  • Core feature: Predominantly psychotic symptoms (hallucinations, delusions) even when mood is relatively stable.  
  • Mood symptoms: May be present but are not the primary feature.
  • Example: Persistent hallucinations, disorganized thinking, social withdrawal, even when not experiencing significant mood episodes.

• Bipolar Disorder with Psychotic Features:

  • Core feature: Manic and depressive episodes that fluctuate significantly.
  • Psychosis: Occurs during manic or depressive episodes (e.g., delusions of grandeur during mania, delusions of guilt during depression).  
  • Example: Experiences of mania with racing thoughts, inflated self-esteem, and delusions of grandeur, followed by periods of severe depression with delusions of guilt and suicidal ideation.

• Major Depressive Disorder with Psychotic Features:

  • Core feature: Persistent and pervasive sadness, loss of interest, and other depressive symptoms.
  • Psychosis: Psychotic symptoms (e.g., delusions of guilt, worthlessness, nihilism) occur exclusively during depressive episodes.
  • Example: Severe depression with persistent thoughts of guilt and worthlessness, accompanied by delusions of impending doom or beliefs of being punished.

• Schizoaffective Disorder:

  • Core feature: Combination of schizophrenia and a mood disorder (bipolar or depressive).  
  • Key distinction: Psychotic symptoms are present even when mood symptoms are absent.
  • Example: Experiences of hallucinations and delusions continuously, alongside significant episodes of mania or depression.

Impact of Misdiagnosis:

Misdiagnosis can have significant consequences for clients, including:

• Ineffective Treatment: Incorrect diagnoses lead to inappropriate treatment plans, potentially worsening symptoms and delaying recovery.
• Side Effects: Medications prescribed for one disorder may have adverse effects on individuals with a different diagnosis.
• Stigma and Discrimination: Misdiagnosis can contribute to stigma and discrimination, impacting social relationships and employment opportunities.  
• Prognosis: Incorrect treatment can worsen the course of the illness and lead to poorer long-term outcomes.

Cultural Influences on Diagnosis

• Cultural Norms: Cultural norms around emotional expression, communication, and beliefs about mental illness can shape how individuals experience and express symptoms.
  • Example: Some cultures may view certain spiritual experiences as normal, while in other cultures, they might be misinterpreted as hallucinations.
