Caffeine consumption found to alter brain structure


A unique placebo-controlled study has found daily caffeine consumption can significantly reduce the volume of gray matter in the human brain. The researchers stress these findings do not imply caffeine negatively impacts the brain but instead suggest the drug may induce a kind of temporary neural plasticity that is worthy of further investigation.
Our brain and central nervous system is generally composed of both gray and white matter. Gray matter consists of neural cell bodies and nerve synapses, while white matter is primarily the bundles and pathways that connect those neural cells.
