Agnosia (also known as primary visual agnosia, monomodal visual amnesia, and visual amnesia) is a neurological disorder characterized by an inability to recognize and identify objects or persons using one or more of the senses. This rare disorder typically results from damage to areas of your brain resulting from strokes, traumatic brain injuries, dementia, or other neurological conditions. Symptoms may vary based on the area of the brain affected:
The inability to recognize something familiar does not mean that your vision quality or thinking ability are impacted. For example, although you may not be able to recognize the object through sight, you might be able to identify the object though another sense.
If agnosia is caused by an underlying disorder, treatment of that disorder may reduce symptoms and help prevent further brain damage. However, treatment of agnosia is symptomatic and supportive, such as rehabilitation through speech or occupational therapy.
How can I or my loved one help improve care for people with agnosia?
Consider participating in a clinical trial so clinicians and scientists can learn more about agnosia and related disorders. Clinical research uses human volunteers to help researchers learn more about a disorder and perhaps find better ways to safely detect, treat, or prevent disease.
All types of volunteers are needed—those who are healthy or may have an illness or disease—of all different ages, sexes, races, and ethnicities to ensure that study results apply to as many people as possible, and that treatments will be safe and effective for everyone who will use them.
