Individuals with neurodegenerative diseases may also present with simultagnosia. Neuroimaging studies have associated simultagnosia with dorsal occipital lobe lesions in Brodmann’s areas 18 and 19. [link.springer.com]

The feature-similarity-gain model, a neural model of selective attention, is briefly presented. [thieme-connect.com]

If symptoms of simultanagnosia are elicited, further neurologic workup may be warranted in the form of brain imaging to evaluate for parieto-occipital damage. [eyewiki.aao.org]

General treatment Treatment varies depending upon the overlying etiology and includes preventing further damage to the parieto-occipital regions. Furthermore, low vision rehabilitation may improve symptoms of simultanagnosia. [eyewiki.aao.org]

Prognosis Prognosis of patients with simultanagnosia is variable and depends upon the extent of brain damage. [eyewiki.aao.org]

Simultanagnosia may result from any etiology that causes damage to these areas (e.g, ischemic, inflammatory, hemorrhagic, infectious, traumatic, neoplastic, neurodegenerative). [eyewiki.aao.org]

Pathophysiology The precise mechanism resulting in simultanagnosia remains poorly understood. [eyewiki.aao.org]
