Cannabidiol benefits and mechanisms shown in mouse study of Dravet syndrome

ScienceDaily | 10/10/2017 | Staff
Cannabidiol is a non-intoxicating substance among the several active compounds derived from Cannabis plants. This molecule can also be produced synthetically.

The results of its use to treat Dravet syndrome are reported in the latest edition of the Proceedings of the National Academy of Sciences, PNAS.

Children - Syndrome - Epilepsy - Seizures - Infancy

Children with this syndrome have severe, difficult-to-control epilepsy. Their seizures, which can be frequent and prolonged, first appear in infancy. As the affected individual grows, intellectual impairments, autism-like behaviors and other debilitating problems can emerge.

Many patients need nearly constant care. Some are at risk for early death. Few therapeutic options exist for this life-long condition.

UW - Medicine - Researcher - William - Catterall

UW Medicine researcher William Catterall, one of the authors of the PNAS paper, noted, "There has been increasing interest in the lay press about parents who have used cannabidiol to successfully treat their children." Catterall is a professor of pharmacology at the University of Washington School of Medicine in Seattle.

Medicinal cannabis use is booming for many disorders, the authors of the paper said, even without enough preclinical evidence or sufficient insights into its mechanism of action.

Success - Trials - Dravet - Syndrome - Patients

The success of small-scale clinical trials for Dravet syndrome patients in reducing the frequency of their seizures, they explained, encourages additional research to determine if cannabidiol might help with other aspects of their condition.

"We have developed a mouse genetic model of Dravet syndrome, which is allowing us to probe more deeply into the possible beneficial effects of cannabidiol," Catterall said. The researchers also wanted to see how the beneficial effects of cannabidiol may depend on changes in the molecular signaling processes that certain brain neurons use to communicate with each other.

Researchers - Mice - Treatment - Severity - Duration

The researchers found that, in mice, cannabidiol treatment effectively reduced the severity and duration of seizures, as well as their frequency. The Dravet mice on low-dose cannabidiol treatment spent more time interacting with mice that were strangers...
