What causes agnosia?
Agnosia
Agnosia can result from strokes, dementia, or other neurological disorders. It may also be trauma-induced by a head injury, brain infection, or hereditary. Additionally, some forms of agnosia may be the result of developmental disorders.[4] Damage causing agnosia usually occurs in either the occipital or parietal lobes of the brain. Although one modality may be affected, cognitive abilities in other areas are preserved.[4]
Social-emotional agnosia
Damage to the right temporal occipital region in humans has been associated with the inability to recognize the faces of loved ones, friends, and pets (considered a form of prosopagnosia). This limits the ability to appropriately interact with familiar people, potentially severely damaging interpersonal relationships. People with social-emotional agnosia may distance themselves from interacting with other people and prefer isolation. Maternal behavior is also severely affected, causing mothers to fail to recognize their children as their own. In human children, deficits in imitating and responding to peer social interactions have been observed. Children with this agnosia have also been found to have hyperorality, an increased tendency to investigate objects with their mouths, which is also a common symptom of Klüver-Bucy syndrome.
