Three eye diseases are associated with an increased risk of patients of Alzheimer’s disease, results of a large-scale population studies.
The researchers were able to detect that patients who had a history of glaucoma, age-related macular degeneration (AMD) or diabetic retinopathy (DR), the risk of developing Alzheimer’s disease was higher by 40-50% than that of the other participants of the test.
In particular, in patients with newly diagnosed glaucoma the chance of developing Alzheimer’s increased by 46%. Similarly, the risk among those who have recently been diagnosed with wet AMD or diabetic retinopathy was 50% higher compared to participants without disease.
In General, the data were analyzed 5,400 people over 65 without dementia at the time of inclusion in the study. The observation was carried out before the development of the dementia participants, exclusion from the study or death.
“We hope that the findings will help to raise awareness among ophthalmologists and primary care physicians. If they have a patient with one of these eye diseases, they should consider cognitive status, said study leader Dr. Cecilia Li (Cecilia S. Lee) from the school of medicine of the University of Washington in Seattle. – Also, if there are concerns about cognitive dysfunction, physicians are encouraged to refer patients to a neurologist for further testing. This is what we recommend at the moment”.
Despite the fact that the study assessed individuals with degenerative conditions of the eye for subsequent risk of Alzheimer’s disease or dementia, the possibility exists that the relationship may be bilateral. According to the authors, when neurologists evaluate patients for possible dementia, they can also ask about the condition of the eye.
The results of the study were published in the journal Alzheimer’s & Dementia.
