Loss of cognitive function in diabetic retinopathy
Diabetic retinopathy does not cause loss of cognitive function. However, cognitive impairment does seem to occur in diabetic retinopathy. Presumably it is also caused by the same diabetic microvascular disease that affects the retina. This is reviewed.
The treatment will be good control of blood pressure, glucose, cholesterol, etc, just as for retinopathy.
It does explain why some people do seem to have a poor memory, or find it particularly difficult adjusting insulin doses.
