Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Anosognosia is the lack of awareness of one's own illness despite general orientation, typically observed in organic brain diseases with focal deficits such as paralysis or visual field disorders. Most frequently described in left-sided hemiplegia with lesions in the right parietal lobe, it represents a specific case of disturbance in body schema recognition.
