The researchers identified its primary driver: neuronal insulin resistance.
“This research suggests that metabolic intervention—whether through dietary approaches like ketogenic diets or supplements—might be most effective when started in one's 40s, well before cognitive symptoms appear.”
Curbing all forms of insulin resistance would appear to be helpful.
I found the following list at:

Acquired causes of the condition, meaning you’re not born with the cause, include:
Excess body fat: Scientists believe obesity is a primary cause of insulin resistance. Excess fat in your belly and around your organs (visceral fat) especially raises your risk.
Physical inactivity: Movement and exercise make your body more sensitive to insulin. Exercise also builds muscle that can absorb blood glucose. A lack of physical activity can lead to the condition.
Food choices: A diet of highly processed foods, high in carbohydrates and saturated fats, has been linked to the condition
Certain medications: Steroids, blood pressure medications, HIV treatments and other medications can cause insulin resistance.
