It’s hard to overstate how devastating neurodegenerative diseases like Alzheimer’s can be. But while there is no cure for Alzheimer’s yet, early diagnosis that results in earlier treatment can help to delay its progression. Today, a doctor diagnosing Alzheimer’s would likely do so through a combination of memory tests, blood tests (to rule out other reasons for memory being affected), and a CT scan. However, in the future it could conceivably be as simple as carrying out a relatively basic eye test. This may speed up diagnosis since it could show positive results before the onset of symptoms.
