Your neurons literally experience less damage at the cellular level, potentially slowing disease progression. Source: Nature – CBD Prevents Oxidative Stress
Glioblastoma tissue shows 765% higher CB2 receptor density than healthy brain, revealing your brain’s natural response to injury involves massively upregulating cannabinoid receptors. This dramatic increase suggests your endocannabinoid system is designed to protect against neurological damage. Understanding this helps explain why external cannabinoids can be so effective – they’re supporting your brain’s own defense mechanisms. Source: PubMed – Cannabinoid Receptor Expression
CBD treatment decreases brain lipid peroxidation by 22.5%, preventing the cascade of cellular damage that characterizes neurodegeneration. This means the fatty membranes surrounding your brain cells remain intact and functional longer. For patients, this translates to preserved cognitive function and potentially slower disease progression. Source: PMC – CBD Modulation of Oxidative Stress
Research reveals CB1 receptors are concentrated 3-fold higher in inhibitory versus excitatory neurons, explaining cannabis’s unique ability to calm overactive brain circuits. This selective distribution means cannabinoids preferentially dampen excessive neural firing without shutting down normal function. If you experience seizures, tremors, or spasticity, this mechanism directly addresses your symptoms’ root cause. Source: Nature – CB1 Receptor Distribution
CBD provides 53% protection against mitochondrial damage in neuroblastoma cells, preserving cellular energy production crucial for neuron survival.
