Caffeine consumption for 4 weeks also significantly reduced hippocampal neurogenesis, a process by which the brain creates new neurons to assist in memory retention, compared to controls during the experiment. The conclusion was that long-term consumption of caffeine could inhibit hippocampus-dependent learning and memory partially through ...
Caffeine is the world's most widely consumed psychoactive drug. [20] [21] Unlike most other psychoactive substances, caffeine remains largely unregulated and legal in nearly all parts of the world.

Among these, rodent studies have suggested caffeine intake may permanently alter the brain's excitability. [23]
In the brain, caffeine blocks or impedes the effect of adenosine, a building block of nucleic acid found in all of the cells in the body. Ordinarily, adenosine is a central nervous system ...
