Overview
Delusions are fixed false beliefs that are resistant to reason or contradictory evidence. They are a hallmark symptom of several psychiatric and neurological conditions, including schizophrenia, bipolar disorder, severe depression, and dementia. While delusions can vary in content, they often significantly impact daily life, relationships, and functioning. In Korea, specialized hospitals and mental health clinics provide diagnostic assessment, psychiatric treatment, counseling, and multidisciplinary care to manage delusions and improve patient quality of life.

What are Delusions?
Delusions are false beliefs firmly held despite clear evidence to the contrary, often influencing a person’s perception of reality.
▶ Types of Delusions:
▶ Persecutory: Belief that one is being targeted, harassed, or conspired against.

▶ Mixed or Unspecified: Combination of delusional themes.
▶ Characteristics: Delusions are persistent, cannot be explained by culture or religion, and often interfere with daily life.

Note: Delusions are a symptom, not a standalone disease, making underlying cause identification critical.
