Delusion is a disorder of?

Appeared in: AIIMS Bhuvneshwar NO- 2018

Explanation

Delusion is defined as a fixed, false, and unshakable belief that is inconsistent with the person's cultural and educational background.
It is fundamentally a disorder of thought content, representing a disturbance in what the person is thinking.
Psychiatric literature classifies delusions as a primary example of a thought content disorder, distinct from disturbances in perception, memory, or judgment.

Option B: Disorders of perception involve misinterpreting or experiencing sensory information that isn't real. Delusion is a false belief, not a false sensory experience.
Option C: Disorders of memory relate to the inability to recall past events or form new memories. Delusions are about current beliefs, not the ability to remember.
Option D: Judgment is the ability to make sound decisions. While delusions can severely impair a person's judgment, the delusion itself is a disorder of thought, not a primary disorder of judgment.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of Delusion as a Mental Disorder as background academic context rather than a clinical decision trigger.
When assessing a patient, it is crucial for a nurse to differentiate between a delusion (thought) and a hallucination (perception) as they indicate different aspects of psychosis and require different management approaches.
Nursing care for a patient with delusions involves not challenging the belief directly, but rather focusing on the underlying feelings and gently presenting reality. This builds trust and reduces agitation.
What if? If a patient believes their food is poisoned (persecutory delusion) and refuses to eat, the immediate nursing priority shifts from reality orientation to ensuring nutrition and safety, possibly by offering pre-packaged, sealed food items.
