What makes you say that? Are there any facts or data behind it?
It kinda makes sense that dementia is one of the big illnesses of our time. People are living longer, and diagnoses are getting better, so of course the numbers are going up. We also have to remember that a few years back, it was a pretty overlooked condition, so there weren’t many records to compare with. Maybe there are some genetic reasons behind it too, but I’ve heard that keeping your brain active with reading and games can really help reduce the effects of the disease.
low cholesterol > bad for the brain, neurons cannot manufacture enough cholesterol, so the liver produces excess and transports it using lipoproteins to tissues that need extra.
widespread statin usage in the general population is causing dimentia

Here's my 2 sats - Alzheimers (the most common of the dementias) is actually a relatively new disease. It was named after Alois Alzheimer, who described the first case he found.
And when was that first case? In 1906! In other words, a NEW DISEASE.
Based on a lot of what I've read, it's a result of increasing consumption of sugar. Nowadays, they're starting to call it Diabetes, type 3.
The truth is, I've wondered that a few times too... It seems like dementia has become almost a silent epidemic of our time. I think there are several reasons behind this: the aging of the population, yes, but also our way of living and eating.
Today we live in a hyper-industrialized world: we eat a lot of processed foods, fill our bodies with sugars, ultra-processed vegetable fats, products with additives, and on top of that, we add chronic stress, little sun, screens all day long, and a completely artificial pace of life. It's as if we're disconnected from what our grandparents did naturally and what was part of their daily lives. We've made a lot of progress as a society, but on the other hand, we've fallen behind.
Eat more good fats: butter, eggs, coconut oil, real meats, avocado... The brain is largely made of fat; it needs that to function properly.
Avoid excessive dairy products (especially industrially pasteurized dairy). I've read studies that link excessive milk consumption with neuroinflammation in some people.
Avoid sugar and refined flours: they increase insulin, which also affects the brain in the long term.
Get some sun every day (when you can): vitamin D is key for brain health.
Get moving. Walking, biking, playing with your kids—moving every day is free medicine. If you can walk somewhere, do it. If you can take the stairs, it's better than taking the elevator.
Read, talk, and have real human relationships: loneliness kills neurons faster than we think.
Avoid aluminum (yes, that too): many pots, deodorants, and processed foods contain it, and it's neurotoxic.
Are we guaranteed that it will never affect us? No. But at least we can do what's in our hands to take care of this organ that is everything.
