Sometimes, a person with serious mental illness truly believes nothing is wrong, even if they're hallucinating, behaving dangerously, or refusing treatment.  This isn't denial or stubbornness. It's called anosognosia (pronounced uh-nah-sig-NO-zee-uh), and it's a medical condition, not a choice.  

Anosognosia is a lack of insight caused by changes in the brain.  It affects a person's ability to recognize they're ill, similar to how someone with a stroke might not realize they've lost movement on one side.  This can be one of the hardest parts of supporting a loved one with mental illness.  

What Families Should Know:

• Anosognosia is common in schizophrenia and bipolar disorder. 
• You can't convince someone with logic alone, it often leads to frustration or conflict.
• Focus on building trust, ensure safety, and finding professionals who understand this condition.
• Over time, people regain insight, especially with treatment and support.
