What Is Psychosis?
Psychosis means a disruption in reality checking. It's when someone loses some contact with reality. This happens in specific, identifiable ways.
Delusions
Fixed, false beliefs held with complete certainty. Not matching facts or evidence.
Example: Believing you're being spied on without any evidence.
Hallucinations
Perceptions without external stimulus. Hearing voices others don't hear is most common.
Can also involve seeing, feeling, tasting, or smelling things.
Disorganized Speech
Jumping topics unpredictably. Thoughts become hard to follow.
Communication becomes fragmented and confusing.
Understanding Symptom Categories
Positive Symptoms
Things added to experience.
  • Hallucinations
  • Delusions
  • Disorganized behavior
  • Unusual movements
Negative Symptoms
Things taken away from experience.
  • Flat emotional expression
  • Low motivation
  • Speaking very little
  • Reduced social drive
Imagine a student suddenly hearing voices calling their name. It's terrifying. They lose focus in class. They avoid friends. They can't organize thoughts or complete assignments.
Cognitive Symptoms
Problems with thinking skills often cause the biggest daily challenges.
  • Difficulty with attention and concentration
  • Memory problems
  • Trouble with planning and organization
These symptoms persist even after voices quiet with treatment.
The Schizophrenia Spectrum: Four Core Diagnoses
Think of the spectrum as a timeline. Duration and symptom patterns distinguish each condition.
1
Delusional Disorder
≥ 1 month
One or more delusions present. Functioning otherwise not markedly impaired. Behavior not obviously bizarre.
2
Schizophreniform
1–6 months
Same symptoms as schizophrenia but shorter duration. About one-third recover fully.
3
Schizophrenia
> 6 months
Long-term illness with functional decline. Has prodromal, active, and residual phases.
4
Schizoaffective
Mixed pattern
Schizophrenia plus major mood episode. Must have 2 weeks psychosis alone.
Types of Delusional Disorder
Persecutory
Belief of being conspired against, spied on, or poisoned.
Grandiose
Inflated worth, power, knowledge, or special relationship with famous person.
Jealous
Conviction that partner is unfaithful without evidence.
Erotomanic
Belief that someone, usually of higher status, is in love with them.
Somatic
Preoccupation with bodily functions or sensations, often believing they have illness.
Mixed
Multiple delusional themes present without one predominating.

Quick Check: Which disorder requires at least 2 weeks of psychosis without mood symptoms? Answer: Schizoaffective Disorder.
Deep Dive: Delusional Disorder
Often misunderstood because people seem perfectly normal in many life areas. Their delusion profoundly shapes specific decisions.
The Challenge
Insight is very low. The belief feels 100% true. Not like a symptom of illness.
Direct arguments don't work. They damage trust and relationships.
Real-Life Examples
Persecutory Type
A man believes his neighbor poisons his water. He seems fine at work.
At home: changing locks, installing cameras, drinking only bottled water.
Grandiose Type
A woman believes she has secret relationship with famous celebrity.
Spends hours writing emails to embassies about her crucial world role.
Management Approach
Build Trust
Never argue directly with delusion. Focus on relationship first.
Explore Gently
Use CBT techniques. Reality testing. Reduce stress from belief.
Consider Medication
Antipsychotics if distress or risk is high. Carefully monitored.
Deep Dive: Schizophreniform & Schizophrenia
These conditions share the same symptom types: positive, negative, and cognitive. The main difference? Duration.
Positive Symptoms
Hallucinations, delusions, disorganized speech and behavior.
Negative Symptoms
Flat affect, low motivation, reduced speech, social withdrawal.
Cognitive Symptoms
Poor attention, memory problems, difficulty planning.
Following Our Student Example
Schizophreniform Diagnosis
Exam stress triggers episode. Becomes suspicious of roommates. Hears whispers. Stops attending class.
Lasts 3 months. Full recovery with treatment.
Short-term episode with positive outcome.
Schizophrenia Diagnosis
Same initial episode. But symptoms continue beyond 6 months.
Residual negative symptoms persist: withdrawn, unmotivated, isolated.
Requires long-term treatment partnership.
Comprehensive Treatment Approach
Medication First Line
Second-generation antipsychotics typically used. Clozapine for treatment-resistant cases.
Psychosocial Support
CBT for psychosis, family therapy, social skills training essential.
Functional Recovery
Supported employment and education programs. Getting back to life.
Early Intervention
Specialized teams for first episode. Dramatically improve outcomes.

Quick Check: Name one negative and one cognitive symptom. Answers: Negative = low motivation or flat affect. Cognitive = poor attention or trouble planning.
Deep Dive: Schizoaffective Disorder
This condition sits on the bridge between schizophrenia and mood disorders. Diagnosing it requires careful attention to timing.
The Diagnostic Challenge
Not Just Schizophrenia
If someone has schizophrenia and sometimes feels down, that's typically just schizophrenia with depressive symptoms.
Not Just Mood Disorder
If someone has bipolar disorder and only gets psychotic during extreme mood episodes, that's bipolar with psychotic features.
True Schizoaffective
Periods of pure psychosis AND distinct major mood episodes. Mixed picture over time.
The Critical Rule
Must have at least 2 weeks where psychotic symptoms occur without any major mood symptoms.
This distinguishes it from mood disorders with psychotic features.
Two Distinct Types
Bipolar Type
Person has experienced at least one manic episode during illness.
Treatment approach: Antipsychotic plus mood stabilizer (lithium or valproate).
Depressive Type
Person has only experienced major depressive episodes, never mania.
Treatment approach: Antipsychotic plus antidepressant medication.
What Causes These Disorders?
There isn't one simple answer. It's a complex interaction of biological, psychological, and social factors.
Biology
  • Genetics—highly heritable
  • Brain chemistry differences (dopamine, glutamate)
  • Subtle brain structure changes
  • Connectivity alterations
Psychology
  • Stress sensitivity
  • Cognitive styles (jumping to conclusions)
  • Trauma history
  • Substance use (especially cannabis in teens)
Social Environment
  • Urban environment stress
  • Migration experiences
  • Childhood adversity
  • High expressed emotion in family
A Helpful Framework
Genetics might load the gun, but the environment pulls the trigger.
Protective Factors
Strong social support, early intervention, stable environment, access to care.
Risk Factors
Family history, childhood trauma, substance use, social isolation, urban stress.

Quick Check: Name one biological and one social risk factor. Answers: Biological = genetics or dopamine dysregulation. Social = urban environment or childhood adversity.
Assessment & Differential Diagnosis
Accurate diagnosis requires a comprehensive, methodical approach. We must consider multiple possibilities.
The Assessment Process
Clinical Interview
Detailed history and mental status exam to observe current symptoms.
Collateral Information
Input from family or friends. Person may lack full insight.
Rule Out Medical Causes
Thyroid, seizures, autoimmune diseases, brain tumors can mimic psychosis.
Substance Screening
Check for drug use or medication side effects causing symptoms.
Rating Scales
Standardized tools track symptom severity over time.
Cognitive Screening
Identify thinking difficulties affecting daily function.
Risk Assessment
Always evaluate suicide risk, self-harm potential, self-neglect.
Differential Diagnosis: What Else Could It Be?
Mood Disorders
Severe depression or bipolar disorder with psychotic features during episodes.
OCD
Severe obsessive-compulsive disorder where intrusive thoughts become almost delusional.
Autism Spectrum
Social communication differences or restricted interests misinterpreted as psychosis.
Complex PTSD
Trauma-related dissociation and flashbacks resembling psychotic symptoms.
Delirium
Sudden medical confusion, often in older adults or during illness.
Dementia
Progressive cognitive decline with possible psychotic features in later stages.
Treatment in Practice: What Actually Works
Effective treatment combines medication with robust psychological and social support. Recovery requires a comprehensive approach.
Medication Management
Find Right Dose
Lowest effective dose minimizes side effects while controlling symptoms.
Monitor Carefully
Watch for weight gain, blood sugar changes, movement side effects.
Injectable Options
Long-acting medications help people who struggle with daily pills.
Pills don't teach skills. That's where psychological and social care become essential.
Psychological Interventions
CBT for Psychosis (CBT-p)
Gently test beliefs. Learn coping skills for voices. Reduce behaviors keeping person stuck.
Family Interventions
Educate family members. Improve communication. Dramatically reduce relapse rates.
Cognitive Remediation
Physical therapy for the brain. Exercises improve attention, memory, planning.
Social Skills Training
Relearn conversation skills. Practice making friends. Prepare for job interviews.
Functional Recovery Support
Supported Employment
Help people return to work quickly. Job coach provides ongoing support.
Evidence shows this approach works better than lengthy pre-training programs.
Supported Education
Help students return to school with accommodations and support services.
Academic coaches help manage coursework and stress.
Early Intervention: A Game-Changer
Specialized teams bring everything together for young people experiencing their first episode.
Combines medication, therapy, family support, employment help, education support.
Result: Much better long-term recovery outcomes. Earlier treatment = better prognosis.

Quick Check: Name two non-medication treatments that improve function. Examples: cognitive remediation, social skills training, family therapy, supported employment.
Busting Myths, Fighting Stigma, Embracing Recovery
Let's correct misconceptions and speak about these conditions with accuracy and compassion.
Common Myths vs. Facts
Myth: People with schizophrenia are violent
Fact: Most are not violent at all. They're far more likely to be victims of violence than perpetrators.
Myth: Schizophrenia means split personality
Fact: It does not. That's Dissociative Identity Disorder, a completely different condition.
Myth: No one recovers from schizophrenia
Fact: Recovery is absolutely possible. Many people manage symptoms well and live meaningful, productive lives.
Language Matters
Don't Say
  • "A schizophrenic"
  • "Suffering from schizophrenia"
  • "Crazy" or "insane"
  • "Split personality"
✓ Do Say
  • "A person living with schizophrenia"
  • "Managing schizophrenia"
  • "Experiencing symptoms"
  • "Living with a mental health condition"
Use person-first language. They are a person first. The diagnosis is just one part of their story.
What Recovery Looks Like
Employment
Returning to meaningful work with appropriate support and accommodations.
Relationships
Building and maintaining meaningful connections with family and friends.
Personal Goals
Pursuing education, hobbies, creative expression, and personal interests.
Daily Living
Managing self-care, maintaining routines, living independently or with support.
