A systematic review of the effect of cannabidiol on cognitive function: Relevance to schizophrenia

Canna Clinical TrialsLeave a comment

Cognitive impairment is a core symptom domain of schizophrenia, neurological disorders and substance abuse. It is characterised by deficits in learning, memory, attention and executive functioning and can severely impact daily living. The efficacy of CBD to improve cognition in schizophrenia cannot be elucidated due to lack of clinical evidence; however, given the ability of CBD to restore cognition in multiple studies of impairment, further investigation into its efficacy in schizophrenia is warranted. Potential mechanisms underlying the efficacy of CBD to improve cognition are discussed.

Recent studies in adults report symptom relief with marijuana use in patients with inflammatory bowel disease (IBD). We assessed the prevalence, pattern, effects, and adverse effects of marijuana use in young adults with IBD. We found a high rate of marijuana use in our cohort of young adults with IBD. Majority of users report symptom improvement but do not inform physicians. Future well-controlled studies are necessary to assess role of marijuana in IBD therapy.

Glaucoma represents several optic neuropathies leading to irreversible blindness through progressive retinal ganglion cell (RGC) loss. Reduction of intraocular pressure (IOP) is known as the only modifiable factor in the treatment of this disorder. Application of exogenous cannabinoids to lower IOP has attracted attention of scientists as potential agents for the treatment of glaucoma.

A user’s guide to cannabinoid therapies in oncology

“Cannabinoid” is the collective term for a group of chemical compounds that either are derived from the Cannabis plant, are synthetic analogues, or occur endogenously. Although cannabinoids interact mostly at the level of the currently recognized cannabinoid receptors, they might have cross reactivity, such as at opioid receptors. The use of cannabinoid therapies could be effective in improving quality of life and possibly modifying malignancy by virtue of direct effects and in improving compliance or adherence with disease-modulating treatments such as chemotherapy and radiation therapy.

Canada has the highest incidence of MS worldwide. Anecdotal evidence reveals that people with MS smoke, ingest or vaporize cannabis for a multiplicity of reasons. With the legal situation in relation to use currently in flux, we undertook a study investigating patterns of use amongst people with MS and their attitudes towards the drug. There is a wide acceptance of cannabis within the MS patient community.

Cannabis and epilepsy: An ancient treatment returns to the fore

Canna Clinical TrialsLeave a comment

Cannabis has been associated with the treatment of epilepsy throughout history, and if ancient Assyrian sources referring to “hand of ghost” are considered credible, this relationship may span four millennia. A tradition of usage continued in Arabic medicine and Ayurvedic practice in India, which led, in turn, to early experiments in Europe and North America with “Indian hemp.” Lack of standardization, bioavailability issues, and ultimately prohibition were all factors in cannabis-based medicines failing to maintain mainstream usage in seizure treatment, but investigation was resumed in the 1970s with interesting signals noted in both laboratory and clinical settings. Early case studies showed promise, but lacked sufficient rigor.

Parkinson’s disease (PD), a neurodegenerative disorder, is the second most common neurological illness in United States. Neurologically, it is characterized by the selective degeneration of a unique population of cells, the nigrostriatal dopamine neurons.  Cannabis and related compounds have created significant research interest as a promising therapy in neurodegenerative and movement disorders.

Medical cannabis: Another piece in the mosaic of autoimmunity?

Canna Clinical TrialsLeave a comment

Legalization of cannabis’ medicinal use is rapidly increasing worldwide, raising the need to evaluate medical implications of cannabis. Due to the supporting evidence of cannabinoids as an immune-modulating agent, research focusing on cannabinoids and autoimmunity has emerged. Several clinical trials in multiple sclerosis, inflammatory bowel disease, and fibromyalgia suggest cannabis’ effectiveness as an immune-modulator.

An Australian nationwide survey on medicinal cannabis use for epilepsy: History of antiepileptic drug treatment predicts medicinal cannabis use

Canna Clinical TrialsLeave a comment

Epilepsy Action Australia conducted an Australian nationwide online survey seeking opinions on and experiences with the use of cannabis-based products for the treatment of epilepsy. The survey was promoted via the Epilepsy Action Australia’s main website, on their Facebook page, and by word of mouth. The main reasons for medicinal cannabis use were to manage treatment-resistant epilepsy and to obtain a more favorable side-effect profile compared to standard antiepileptic drugs.
