Which of the following best defines psychosis?

A. Loss of memory
B. Inability to feel emotions
C. Inability to distinguish what is real from what is not
D. Excessive happiness

Correct Answer: C. Inability to distinguish what is real from what is not

Explanation:
Psychosis is a state where a person cannot differentiate reality from non-reality, often involving delusions or hallucinations.

Clarification:
Psychosis is not unique to schizophrenia—it can occur in conditions like bipolar disorder, substance use, or medication reactions.

According to proper diagnostic criteria, how many symptoms are required to diagnose schizophrenia?

A. One symptom for 1 month
B. Two symptoms for 1 month
C. Two or more symptoms, with at least one being delusions, hallucinations, or disorganized speech

Correct Answer: C. Two or more symptoms, with at least one being delusions, hallucinations, or disorganized speech

Explanation:
Diagnosis requires ≥2 symptoms, and at least one must be:

• Delusions

• Hallucinations

• Disorganized speech

Clarification (Important Correction):
The video missed this rule. Not just any two symptoms qualify.

What is the minimum total duration required for a schizophrenia diagnosis?

A. 1 week
B. 1 month
C. 3 months
D. 6 months

Correct Answer: D. 6 months

Explanation:

• Active symptoms: ≥1 month

The video only mentioned 1 month, but diagnosis requires 6 months total.

Which of the following is an example of a delusion?

A. Feeling sad after losing a job
B. Believing you are better than others at sports
C. Believing your spouse was cloned from your skin
D. Hearing your name once when tired

Correct Answer: C. Believing your spouse was cloned from your skin

Explanation:
Delusions are fixed false beliefs that cannot be corrected, even with evidence.

Clarification:
Normal beliefs or opinions (like confidence in sports) are not delusions.

Which of the following is TRUE about hallucinations in schizophrenia?

A. They only occur during sleep
B. They occur when fully awake and alert
C. They are always visual
D. They are always harmful

Correct Answer: B. They occur when fully awake and alert

They can involve any sense, but auditory hallucinations are most common.

What is tangential thinking?

A. Speaking very briefly
B. Returning to the main point quickly
C. Going off-topic and never returning
D. Speaking with no emotion

Correct Answer: C. Going off-topic and never returning

Explanation:
Tangential thinking means the person drifts away from the topic and does not come back.

Clarification:

• Circumstantial speech = off-topic but returns (NOT schizophrenia-specific)

• The video correctly distinguished these.

Which of the following is a negative symptom?

A. Hallucinations
B. Delusions
C. Reduced emotional expression
D. Agitation

Correct Answer: C. Reduced emotional expression

Explanation:
Negative symptoms involve loss or reduction of normal functions, such as:

• Flat affect

• Low motivation

• Reduced speech

Clarification (Important Correction):
The video said patients “need less stimulation,” but the accurate concept is loss of normal emotional and behavioral function, not comfort with inactivity.

Which feature helps distinguish schizophrenia from bipolar disorder with psychosis?

A. Presence of hallucinations
B. Presence of delusions
C. Presence of mood symptoms
D. Disorganized speech

Correct Answer: C. Presence of mood symptoms

Explanation:

B. It is always episodic like depression
C. It varies; may be chronic or have relapses and remissions
D. It disappears completely after treatment

Correct Answer: C. It varies; may be chronic or have relapses and remissions

Explanation:
Schizophrenia often has a chronic course, but many patients experience:

• Relapses

• Partial recovery

Clarification (Important Correction):
The video saying it is “not episodic” is too absolute.

Which best describes schizoaffective disorder?

A. Only mood symptoms
B. Only psychotic symptoms
C. Psychosis only during mood episodes
D. Psychosis + mood episodes, with at least 2 weeks of psychosis without mood symptoms

Correct Answer: D. Psychosis + mood episodes, with at least 2 weeks of psychosis without mood symptoms

Explanation:
Key requirement:

• Psychosis occurs independently of mood episodes

Clarification (Important Correction):
The video simplified it too much as just a “combination.”

A. Patients always know their beliefs are false
B. Patients usually recognize delusions immediately

B. Only medications are needed
C. Many patients improve, but full recovery is not always achieved

The video correctly noted that full resolution is uncommon, especially for cognitive deficits.

For a diagnosis of schizophrenia, symptoms must cause:

A. Mild discomfort only
B. No functional impact
C. Significant impairment in social, occupational, or academic functioning
D. Only emotional distress

Correct Answer: C. Significant impairment in social, occupational, or academic functioning
