In that case, you have early onset essential tremor, not age-related essential tremor. I believe only age-related essential tremor has increased risk of dementia. For example: In an adjusted model, ET cases with tremor onset after age 65 years were twice as likely to develop incident dementia than were controls (RR = 1.98, 95% CI = 1.14–3.45, P = 0.01), whereas ET cases with tremor onset < age 65 years and controls were equally to develop incident dementia (RR = 0.74, 95% CI = 0.19–3.20, P = 0.79). https://movementdisorders.onlinelibrary.wiley.com/doi/10.1002/mds.21553 https://movementdisorders.onlinelibrary.wiley.com/doi/10.100... However, I think essential tremor needs more research in general.
