Central Nervous Disease and Cannabis


It is estimated that over 50 million Americans are affected by disease or disorders of the spinal cord and brain.  Central nervous system disease affects either the spinal cord (myelopathy) or brain (encephalopathy).  Disorders includes spinal cord injury, memory loss, addiction, schizophrenia, learning disability, depression, violence, stroke, brain injury, dementia, and many others.  Scientists have studied cannabis compounds when applied to CNS disease and below you will find those studies.

Therapeutic Potential of Cannabinoids in CNS Disease
The major psychoactive constituent of Cannabis sativa, delta(9)-tetrahydrocannabinol (delta(9)-THC), and endogenous cannabinoid ligands, such as anandamide, signal through G-protein-coupled cannabinoid receptors… Signalling is mostly inhibitory and suggests a role for cannabinoids as therapeutic agents in CNS disease… Anecdotal evidence suggests that patients with disorders such as multiple sclerosis smoke cannabis to relieve disease-related symptoms. Cannabinoids can alleviate tremor and spasticity in animal models of multiple sclerosis… Evidence suggests that cannabinoids may prove useful in Parkinson’s disease… The inhibitory effect of cannabinoids… suggests they may be potent neuroprotective agents…cannabinoids may be effective analgesics. Indeed, in clinical trials of postoperative and cancer pain and pain associated with spinal cord injury, cannabinoids have proven more effective than placebo… Acute adverse effects following cannabis usage include sedation and anxiety. These effects are usually transient and may be less severe than those that occur with existing therapeutic agents. The use of nonpsychoactive cannabinoids such as cannabidiol may allow the dissociation of unwanted psychoactive effects from potential therapeutic benefits… This review highlights recent advances in understanding of the endocannabinoid system and indicates CNS disorders that may benefit from the therapeutic effects of cannabinoid treatment.

Cannabinoids.  Current Drug Targets CNS Disorders Neurol Disorders
Since the discovery of an endogenous cannabinoid system, research into the pharmacology and therapeutic potential of cannabinoids has steadily increased… Properties of CB receptor agonists that are of therapeutic interest include analgesia, muscle relaxation, immunosuppression, anti-inflammation, antiallergic effects, improvement of mood, stimulation of appetite, antiemesis, lowering of intraocular pressure, bronchodilation, neuroprotection and antineoplastic effects… CB receptor antagonists are under investigation for medical use in obesity and nicotine addiction. Additional potential was proposed for the treatment of alcohol and heroine dependency, schizophrenia, conditions with lowered blood pressure, Parkinson’s disease and memory impairment in Alzheimer’s disease.

Antiepileptic Potential of Cannabidiol Analogs
These data suggest anticonvulsant requirements of 2 free phenolic hydroxyl groups, exact positioning of the terpinoid moiety in the resorcinol system and correct stereochemistry. Moreover, findings of separation of anticonvulsant from neurotoxic and psychoactive activities, notably with CBD diacetate, suggest that additional structural modifications of CBD may yield novel antiepileptic drugs.

Structure-Anticonvulsant Activity Relationships of Cannabidiol Analogs
The compounds were evaluated for anti-convulsant activity in seizure susceptible (AGS) rats and for neurotoxicity in the rat rotorod (ROT) test. Comparisons of stereoisomers of CBD and several analogs revealed a general lack of stereoselectivity for anticonvulsant and other CNS properties of this class of compounds.

Antiepileptic Potential of Cannabidiol Analogs
Also, CBD and all analogs were not active in tetrahydrocannabinol seizure-susceptible rabbits, the latter a putative model of cannabinoid psychoactivity in humans. These data suggest anticonvulsant requirements of 2 free phenolic hydroxyl groups, exact positioning of the terpinoid moiety in the resorcinol system and correct stereochemistry. Moreover, findings of separation of anticonvulsant from neurotoxic and psychoactive activities, notably with CBD diacetate, suggest that additional structural modifications of CBD may yield novel antiepileptic drugs.

An Electrophysiological Analysis of the Anticonvulsant Action of Cannabidiol on Limbic Seizures in Conscious Rats
An electrophysiological analysis of the anticonvulsant action of cannabidiol (CBD, from cannabis) on limbic seizures in conscious rats…CBD was the most efficacious of the drugs tested… Other properties of CBD were also noted: For example, compared with delta 9-THC, it is a much more selective anticonvulsant vis-à-vis motor toxicity…These characteristics, combined with its apparently unique set of electrophysiological properties, support the suggestion that CBD has therapeutic potential as an antiepileptic.

Pharmacology and Experimental Therapeutics Cannabidiol Displays Antiepileptiform and Antiseizure Properties In Vitro and In Vivo
“CBD (cannabidiol) is the major nonpsychoactive component of Cannabis sativa whose structure was first described by Mechoulam and Shvo (1963); CBD has recently attracted renewed interest for its therapeutic potential in a number of disease states. CBD has been proposed to possess anticonvulsive, neuroprotective, and anti-inflammatory properties in humans… within the CNS, CBD has been proposed to be protective against epilepsy, anxiety, and psychosis and to ameliorate diseases.

Cannabidiol–Antiepileptic Drug Comparisons and Interactions in Experimentally Induced Seizures in Rats
“A comparison of the anticonvulsant… effects of cannabidiol (CBD), delta 9tetrahydrocannabinol, cannabinol and antiepileptic drugs (phenytoin, phenobarbital, carbamazepine, chlordiazepoxide, clonazepam, ethosuximide and trimethadione) was made… These data indicate that CBD is an effective anticonvulsant with a specificity more comparable to drugs clinically effective in major than minor seizures. Furthermore, it appears that CBD enhances the anticonvulsant effects.
