9. Hypertension and its trajectory — The researchers confused within the earlier version of the Fee’s publication that hypertension can enhance the chance of all-cause dementia, Alzheimer’s illness and vascular dementia.17
10. Weight problems — Analysis means that creating weight problems throughout midlife can enhance the chance of all-cause dementia.18 These findings had been additionally supported in one other research, including that the chance is larger in folks older than 65 years in comparison with different age teams.19
