Delusional Disorder
Clinically reviewed by Dr. Barkha ChikaraChief Medical Officer, MD (Psychiatry) from NIMHANS · Last reviewed October 2026Delusional disorder is a condition in which a person holds a fixed false belief for at least a month, for example that they are being followed, deceived by a partner or seriously ill, while the rest of their thinking and daily functioning stay relatively clear. It can be assessed and managed.
About 1 in 10 adults in India lives with a mental disorder (National Mental Health Survey, 2015-16). You are not alone.

- “I am sure something is true but others say it is not”
- “I strongly believe my spouse is cheating without proof”

How it is diagnosed
A psychiatrist listens carefully to the belief without arguing, asks how long it has lasted and how it affects life, and rules out medical causes, substance use and other conditions.
Treatment and support
- Treatment usually involves a doctor's care over time
- Building trust, since people may not feel they are ill
- CBT approaches that explore the belief gently
- Family support and guidance on not arguing with the belief
- Regular follow-up

A psychiatrist, with your family if you wish, asks about what you have been experiencing, sleep, stress and substance use, and checks your safety.
Who is involved
A psychiatrist leads care, and family members are invited to take part because their support makes a difference.

Can delusional disorder be treated?
Yes, though people may take time to accept help. A trusting relationship with a clinician is key.
How should family respond?
Stay calm, avoid arguing or agreeing, and encourage a consultation.
