On 10 September, an international team of researchers published an article on areas in the retina that could indicate changes in mild Alzheimer’s disease (AD) in the journal Nature. The team analysed the differences in 10 retinal layers between 19 patients with mild Alzheimer’s disease (AD) and a control group of 24 volunteers. The mean thickness of each individual layer was compared. This showed the researchers that the outer segment layer of patients with AD showed significant thinning. The researchers reported that when the layers were compared point-by point, patients with AD showed statistically significant thinning, in comparison with the control group, in irregular regions of total retina and nerve fiber, ganglion cell, inner plexiform, inner nuclear and outer segment layers. These findings may have future implications for the improvement in diagnostic procedures of AD.
