<unk>  is a condition in which a person with a disability is cognitively unaware of having it due to an underlying physical or psychological (e.g., PTSD, Stockholm syndrome, schizophrenia, bipolar disorder, dementia) condition.<unk>  can result from physiological damage to brain structures, typically to the parietal lobe or a diffuse lesion on the fronto-temporal-parietal area in the right hemisphere, and is thus a neuropsychiatric disorder. A deficit of self-awareness, it was first named by the neurologist Joseph Babinski in 1914. Phenomenologically,<unk>  has similarities to denial, which is a psychological defense mechanism; attempts have been made at a unified explanation.<unk>  is sometimes accompanied by asomatognosia, a form of neglect in which patients deny ownership of body parts such as their limbs. The term is from Ancient Greek ἀ- a-, 'without', νόσος nosos, 'disease' and γνῶσις gnōsis, 'knowledge'. It is also considered a disorder that makes the treatment of the patient more difficult, since it may affect negatively the therapeutic relationship.
