Anosognosia

Anosognosia is a condition that some people have when they cannot recognize or know they have a physical or mental illness. It can be like a person cannot tell that they have a condition and do not understand why they have it even though they can feel it. It can be very hard for a person to learn that they have anosognosia because their brain cannot understand the reality that their body's feelings or thoughts are not accurate.
