Anosognosia is a condition in which someone refuses to recognize a physical, mental or behavioral health condition.
Strokes and traumatic brain injuries are common causes of physical anosognosia, but the mental and emotional varieties of the condition — also known as “lack of insight” — are less understood.
Researchers think damage to high-level processing of sensory information interferes with a person’s ability to sense bodily or spatial representations. In some cases, individuals with anosognosia may have multiple impairments but only acknowledge one impairment while remaining unaware of the others.
