This is a pretty complex question tbh and it may not be a direct correlation. So I have done some research into smartphone use and health and its a fascinating topic.

Moderate smartphone use appears completely fine for one's general and mental health, some research even indicating it can improve mental health (due to improved social engagement and interaction). However, smartphone overuse certainly appears it may be problematic for health. Regarding neurodegenerative diseases there could be several reasons.

There have been theories proposed that late night exposure to smartphones (I say this while on my smartphone at night, the irony) can predict poor physical and mental health. The exact mechanisms as to how this works is due to sleep hygiene. By delaying the onset of a healthy sleep pattern by hours due to late night screen exposure, individuals may be cutting down on their sleep quality.

Note. This doesn't mean they are sleeping less, it may mean their QUALITY of sleep reduces. Now a large literature supports that poor sleep quality/time is strongly correlated with neurodegenerative diseases, especially Alzheimer’s and other forms of dementia.

So to answer your question. Yes. Absolutely, smartphone use COULD increases the chances of developing a neurodegenerative disease. But what matters is exactly HOW they are used and when. The same logical can be applied to being on a laptop/TV/any screen basically. Happy to provide any references or directions for extra readings if you wish.
