I would look for CBD (cannabidiol) dominant strains which have shown to exhibit neuroprotective, anti-inflammatory, anti-spasmodic effects (among many other benefits). It is best to incorporate some THC because they enhance each others effects. Please discuss incorporating CBD dominant strains into your treatment regimen with your neurologist. I have included some studies done below which may be helpful.
