Core Tip

Core tip: Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system and causes disability, neuropathic pain, spasticity and tremor in affected patients. Although illegal, users of cannabis report relief from pain and spasticity, probably due to the endogenous cannabinoid system that exists. Cannabinoid receptor type-1 (CB1)-deficient mice accrue greater levels of neurodegeneration and poorly tolerate inflammatory and excitotoxic insults after immune attack in a model of MS, experimental allergic encephalomyelitis. Treatment of animals affected by experimental allergic uveitis (EAU) with CB1 agonists also provided significant neuroprotection from the consequences of EAU, suggesting that cannabinoids may slow down neurodegeneration in MS.
