Alzheimer’s and Aphantasia

I’m 66 years old. I’ve become aware of increased memory difficulties in the past few years. This is of concern, particularly because Alzheimer’s disease runs in my family. I’m trying to understand if my aphantasia which I’ve also discovered in the past few years is related to my memory decline. As far as I can remember, going back, I never had good visualization. I didn’t really think about it, just thought that visualization wasn’t my strong suit. I had flashes of images, but nothing more. In the last year, I’ve realized that I now have no visualization, I just see black in my mind when I close my eyes. Can aphantasia get worse?

I read after doing a google search that aphantasia can be a harbinger of Alzheimer’s disease.

Is there any research on this?

Thanks in advance, Nadia

I’ve seen reference to an article that raises the hypothetical question of aphantasia having a role in diagnosing neurogenerative diseases. However, I’m not sure that any correlation between aphantasia and Alzheimer’s disease has actually been established.

But there is a paper from Hungary that evaluated distributions of vividness of visual imagery in populations divided into different age groups. You can find a link to a video presentation on the subject as well as a link to the published paper here:

The paper shows a decrease in vividness of visual imagery between younger and older age groups. This was a population study, not a longitudinal study that followed the same individuals over time to evaluate changes. So there definitely are limitations with respect to providing an answer to your question about whether aphantasia can get worse.

Thank you Alice. I will check out this paper.
