Quick Answer: How Do You Treat Agnosia?


When possible, the cause of agnosia is treated (eg, surgery and/or antibiotics for cerebral abscess, surgery and/or radiation for brain tumor).

Rehabilitation with speech or occupational therapists can help patients learn to compensate for their deficits.

What causes agnosia?

Causes. Agnosia is caused by damage to the parietal, temporal, or occipital lobe of the brain. These areas store memories of the uses and importance of familiar objects, sights, and sounds and integrate memory with perception and identification. Agnosia often occurs suddenly after a head injury or stroke.

How does visual agnosia affect the brain?

It is not due to a deficit in vision (acuity, visual field, and scanning), language, memory, or intellect. While cortical blindness results from lesions to primary visual cortex, visual agnosia is often due to damage to more anterior cortex such as the posterior occipital and/or temporal lobe(s) in the brain.

What are the symptoms of agnosia?

Symptoms. People with primary visual agnosia may have one or several impairments in visual recognition without impairment of intelligence, motivation, and/or attention. Vision is almost always intact and the mind is clear. Some affected individuals do not have the ability to recognize familiar objects.

What is agnosia and aphasia?

This chapter describes medical conditions of aphasia, apraxia, and agnosia. Aphasia is a disturbance of language unexplained by articulatory impairment or sensory loss. Agnosia is a failure of recognition that is not explained by impaired primary sensation—tactile, visual, and auditory—or cognitive impairment.
