[9] While agnosics suffer from severe deficits, patients' visual acuity and other visual abilities such as perceiving parts and colours remain intact.

Bálint's syndrome symptoms can be quite debilitating since they impact visuospatial skills, visual scanning and attentional mechanisms. [8] Since it represents impairment of both visual and language functions, it is a significant disability that can affect the patient's safety—even in one's own home environment, and can render the person incapable of maintaining employment.
