Studies show caffeine reduces Cerebral BloodFlow 27-40%... does this mean caffeine is damaging brain cells? Why not? Reduced blood flow is NOT good!?!
If that were: The whole truth, caffeine would not be the most widely used psychoactive agent on Earth. Caffeine also enhances alertness, enhances mental focus and improves score for all comers in tests of performance and cognition. So, this is what happens when you take one isolated physiologic response and try to then conclude something more complex about cell function, especially the brain. Neurobiology=??? ...Read more

In the usual way: The same way that anything gets into the brain: Arteries carry blood to the brain. The arteries branch into arterioles which branch into capillaries. Substances diffuse OUT of the capillaries into tissue & waste products diffuse INTO the capillaries from the tissues. It's true for every substance and every organ, not just the brain & caffeine. I guess you skipped human physiology in high school. ...Read more

How much is my brain damaged if I have been addicated to caffeine for 10 years? Ex. I drink energy drinks and pop on a daily basis if I don't I can't think or wake up
Probably no damage: It is conceivable that extraordinary quantities of caffeine could produce brain damage, but not likely. Excessive use or "addiction" may cause problems, even possible brain changes, but these would not be classified as "damage." You may be painting a picture of addiction, not actual damage -- this could be better addressed by a professional evaluation. ...Read more

What would cause me to feel real shaky inside. I don't drink a lot of caffeine. I do have a meningomia brain tumor had it for 10 yrs its grow minimal?
That Depends...: A general 'shakiness' can be due to weakness, or it could represent a metabolic condition unrelated to your tumor. Some meningiomas are benign and barely grow over decades, but some can cause irritation to the surface of the brain around them. I would have a thorough medical evaluation and a follow-up MRI to see which this could be. ...Read more

Not important if you are healthy. ...Read more

Is it true to not drink caffeine drinks or eat fish while pregnant? I thought fish would be healthy for the babys brain development.

No libido. No motivation. Low energy. Easily fatigued. Nerd a caffeine stimulant through out the day. Cold hands and feet. Brain fog, unable to focus.?
Is caffeine better than taking medications or supplements which boosts focusing and memory like doxiderol or cerebral success?
Interesting question: Of course both companies selling these products would say no. Yet, caffeine is strongly in both. Why include it? All the individual herbs and nutritional components have some studies of cognitive effect, but none is curative of any condition. There are also no studies of the whole products as sold. So for me, advertising themselves as suitable substitutes for stimulants is fishy. For you? ...Read more
