When adenosine is blocked, levels of the neurotransmitters norepinephrine and dopamine increase, causing nerve cells to increase their ability to conduct nerve impulses throughout the body.
Many high-reliability studies have been conducted showing that in addition to helping to enhance nerve impulse transmission, coffee can also improve other brain functions including memory, mood, levels energy, reaction time, and general neurological function.

Caffeine stimulates the nervous system to command the enzymes to hydrolyze fats in the body in a powerful way.

Parkinson's disease is the 2nd most common neurodegenerative disease worldwide, second only to Alzheimer's. Parkinson's can cause nerve cells to die, thereby reducing the ability to conduct nerve impulses by reducing the amount of dopamine in the brain. Like Alzheimer's disease, Parkinson's disease also has no specific treatment, which makes prevention much more important. Studies have shown that people who drink a lot of coffee have a 32-60% lower risk of Parkinson's disease, the main factor being the caffeine in coffee.
