"Eureka!"  (Meaning "I have found it.")  The moment when an idea "comes to you" is often

• after pondering it for a long time,
• studying it in depth, and
• connecting seemingly unrelated areas of knowledge.

In my case, the seemingly unrelated areas were:

• ADHD in children and adolescents
• Anxiety/depression and stress related difficulties in adulthood
• Alzheimer's (dementia) in Seniors.

Breaking away from mainstream "treatments" for ADHD allowed me to see that for many people their ADHD symptoms were a result of not providing the brain what it needs from the environment, nutrition, and development. Then I saw that these same things had an impact on many adults who experienced anxiety and stress-related difficulties. And then I came across an article about "metabolic enhancement for neurodegeneration" for Alzheimer's -- wow, same thing.

My theory: these three seemingly unrelated and seemingly entirely different "disorders" are just three manifestations of what I'll call (for now) "brain adaptation fatigue."  

Let me explain with a metaphor comparing and contrasting your brain and a car engine.  If we put poor quality gasoline in our car, it will go, but it will probably sputter and jump.  If we continue this and add to it that we don't change the oil, the car will still go (probably) but become sluggish and get poor gas mileage.  If we continue these, don't change the spark plugs or put on new tires -- eventually, the car will end up a rusted heap in the junkyard.  (I'll improve this metaphor -- but for now, I hope you get the idea.)

ADHD is like the car sputtering and jumping.  Anxiety/depression and stress responses are like the car becoming sluggish and getting poor gas mileage (except cars don't know they are getting poor gas mileage -- humans do, and that results in anxiety).  And an Alzheimer's brain is a "rusted heap" from decades of misuse and lack of care.

The "Eureka" is that we can "fix" or prevent all these -- ADHD, anxiety/depression, Alzheimer's (well, if we start soon enough) -- by doing the same things.  These things are taking proper care of the brain and providing all the things a brain needs.  Follow along here to see what those things are.
