ASENSIO-SANCHEZ, VM. et al. Visual symptoms as the first manifestation of Alzheimer's disease. Arch Soc Esp Oftalmol [online]. 2006, vol.81, n.3, pp.169-172. ISSN 0365-6691.

Case report: We report a 59-year-old patient with difficulty in visual perception, difficulty reading and episodes of dyschromatopsia. The ocular examination was unremarkable. Structural neuro-imaging and neuro-opthalmology tests were normal. Positron emission tomography scanning showed decreased metabolism in the parieto-occipital cortex bilaterally. Several months later the patient developed Alzheimer´s disease. Discussion: Visual symptoms may be the first manifestation of Alzheimer´s disease.

Keywords : Alzheimer´s disease; visual symptoms; PET.
