What is "delusion"?

Delusion is a mental condition where someone strongly believes in something that is not true or lacks evidence, even when shown contradictory facts. These false beliefs are resistant to change, and they can cause significant distress or problems in daily life. Delusions can take many forms, such as believing to have special powers, being oppressed by others, or having a special connection to someone famous. Treatment for delusions often involves therapy and medication to help manage symptoms and promote clearer thinking.
