Arthur T Knackerbracket has found the following story:
One in three cases of dementia could be prevented if more people looked after their brain health throughout life, according to an international study in the Lancet.
It lists nine key risk factors including lack of education, hearing loss, smoking and physical inactivity.
The study is being presented at the Alzheimer's Association International Conference in London.
By 2050, 131 million people could be living with dementia globally.
There are estimated to be 47 million people with the condition at the moment.
[...] These risk factors - which are described as potentially modifiable - add up to 35%. The other 65% of dementia risk is thought to be potentially non-modifiable.

To get nice boost/cutoff frequencies, you'll want a bunch of gain (numerous operational amplifiers).
Heh. You're taking me back to the 1970s and a plug-in for Tektronix tube-based oscilloscopes. [google.com]
(The gear was more than a decade old then.)
It was loaded up with vacuum tubes (peanut tubes) and was about the size of a 24oz loaf of bread, the short fat type. [google.com]
Your notion would be pretty bulky--even using the tiniest tubes available. [google.com]
