What is associative visual agnosia?

Can visual agnosia be cured?
Treatment of Visual Agnosia. Visual agnosias are likely to hinder the day-to-day functioning of patients; they may also make life difficult for those around the patient, such as family and friends. Since brain lesions underlie agnosias, there is no direct treatment for them currently.
