This study of patients with seizures from tuberous sclerosis complex (the growth of many non-malignant tumors) found CBD to be effective & well-tolerated

Long-Term Safety, Efficacy of Add-on Cannabidiol (CBD) for Treatment of Tuberous Sclerosis Complex-Associated Seizures in an Open-Label Extension

This review looks at the endocannabinoids in the hypothalamus & how they relate to obesity

Hypothalamic endocannabinoids in obesity: an old story with new challenges

A review like this confirms our research showing that a moderate amount of CBD-rich hemp extracts each day will help people.

In a related clinical study, people with the highest risk of obesity had lower levels of CB1 receptors

Obesity risk is associated with altered cerebral glucose metabolism and decreased μ-opioid and CB 1 receptor availability

“These results suggest that the hereditary mechanisms promoting obesity may be partly mediated via insulin, opioid and endocannabinoid messaging systems in the brain.”

A review of the CB2 receptors in the hippocampus

Hippocampal Cb 2 receptors: an untold story

The common story has always been that there’s lots of CB1 receptors in the brain & not that many CB2 receptors (mostly related to the brain’s immune system). But new research is finding more & more CB2 receptors in the brain. Their expression in the hippocampus is important because it’s a center of memory. It helps to convert short term memories to long term memories, it’s responsible for spatial memory & navigation & it’s one of the first brain regions damaged in Alzheimer’s disease. This review suggests targeting the CB2 receptors for diseases related to memory & for deficits in adult neurogenesis (growth of new brain cells).

In related research, the activation of CB1 receptors was found to protect hippocampal neurons

Cannabinoid CB1 and CB2 receptors differentially regulate TNF-α-induced apoptosis and LPA1-mediated pro-survival signaling in HT22 hippocampal cells

In human immune cells, treatment with CBD significantly lowered pro-inflammatory cytokines

Cannabidiol selectively modulates interleukin (IL)-1β and IL-6 production in toll-like receptor activated human peripheral blood monocytes

In a mouse model of Alzheimer’s disease, CBD coated by nano-particles reduced brain plaques, increased CB1 & CB2 levels & improved learning & memory
