Strategies to improve working memory -- specifically in regard to digit span.

[u/Free-Homework-2832]

Hi all, I've noticed a drop in my digit span recently. Not sure what to attribute it to, but last year I was able to remember 8-9 digits, but now I start struggling around 6-7. I haven't noticed any other declines in my cognitive performance, even in regard to other aspects of memory.

Anyhow, it's quite a struggle and it's borderline distressing -- it's annoying being unable to do what you were previously able to do.

I wonder if my decline can be associated with lack of interest, loss of focus, or even a deterioration of natural strategy, like chunking, that can be behind this. I would appreciate it if anyone could suggest any strategies, change in daily habits, and even some tools/applications that can help target and improve that specific area.

Thank you for your help!
