Medical Marijuana and Treatment of Pediatric Epilepsy Patients

Medical Marijuana in the Pediatric Population With Epilepsy—What You Should Know

A recent review has discussed the known benefits of treating children who are suffering from epilepsy with cannabis-based medicine. Medical marijuana (MM) is a viable option for treating this population that comes with risks due to the high that comes from THC and its legal status as a Schedule 1 drug. The legal status is currently preventing larger scale research to be done so that physicians can better educate parents on how to care for a child taking MM.

Video: Cannabis, Cannabinoids, and Sleep: a Review of the Literature

Researchers published a literature review that investigates the relationship between cannabis and sleep. They examined six major sleeping disorders: insomnia, sleep apnea, REM behavior disorder, nightmares, sleep with chronic pain, and daytime sleepiness.

They found that THC might worsen daytime sleepiness and delayed onset of sleep; however, THC might help patients who suffer from sleep apnea and nightmares. Meanwhile, CBD might reduce daytime sleepiness and insomnia while increasing the total amount of sleep.

Honey and Garlic Help Heal Burn Wounds

Euphorbia honey and garlic- Biological activity and burn wound recovery

A recent study has shown that a combination of euphorbia honey and garlic can help heal burn wounds. Euphorbia honey and garlic have antioxidant, microbial, and healing properties that have now been confirmed to be effective when treating wounds resulting from exposure to extreme heat. Combining natural ingredients has been common in traditional medicine for years, but now western medicine is beginning to look at more natural compounds to aid in recovery and treatment methods.

Cannabidiol as a suggested candidate for treatment of Autism Spectrum Disorder

This 2018 review summarizes the available data regarding the safety and effectiveness of medical cannabis in young ASD patients. Here’s our video adaptation:

  • Autism spectrum disorder (ASD) defines a group of neurodevelopmental disorders that are frequently associated with general cognitive deficits
    • DSM-5 criteria of ASD include:
      • A. Persistent deficits in social communication and social interaction
      • B. Restricted, repetitive patterns of behavior, interests, or activities
      • C. Symptoms must be present in the early developmental period
      • D. Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.
      • E. These disturbances are not better explained by intellectual disability or global developmental delay
    • ASD is frequently accompanied by co-morbidities:
      • sleep disorders
      • attention-deficit/hyperactivity disorder (ADHD)
      • Psychosis
      • Anxiety
      • mood and cognitive disorders
      • epilepsy
    • Despite it being one of the most severe chronic childhood disorders with relatively high prevalence, morbidity and impact on the society, no effective treatment for the core symptoms of ASD is available yet.
    • There is increasing interest in cannabinoids, especially cannabidiol (CBD), as monotherapy or add-on treatment for the core symptoms and co-morbidities of ASD.
  • CBD Use for Epilepsy
    • 20-30% of people with ASD also suffer from epilepsy
    • Surveys conducted among parents of children suffering from epilepsy suggest improvement following treatment with CBD-enriched cannabis extracts. These results however, do not necessarily apply when it comes to treating adults with epilepsy (Alexander et al., 2009).
    • Still, in a retrospective study that examined the effect of CBD enriched medical cannabis oil on children with intractable epilepsy, the treatment caused a reduction in seizure frequency in 89% of patients (Tzadok et al., 2016).
  • CBD Use in Psychiatry
    • CBD in Psychosis
      • In some cases, psychosis can be a comorbidity of ASD, with the simultaneous onset of schizophrenia at adolescence or early adulthood (Sagar et al., 2013).
      • Ineffective
        • A 2006 study that investigated the influence of CBD as monotherapy in treatment-resistant schizophrenia found that it was ineffective (Zuardi et al., 2006).
      • Effective
        • But a 2018 study showed that, in patients with schizophrenia, adding CBD to ongoing antipsychotic treatment resulted in greater antipsychotic activity and beneficial effects, as compared to placebo add-on (Mcguire et al., 2018).
    • CBD and Anxiety
      • Many ASD patients suffer from anxiety disorders that harm their quality of life (Gu, 2017; Haan et al., 2008; Perrin, 2011).
      • CBD may possess anxiolytic effects both in animals and humans (Bergamaschi et al., 2011).
      • When tested in humans, CBD showed an anxiolytic effect in patients that suffer from social anxiety disorder (SAD), contrary to THC that may induce anxiety (Devinsky et al., 2014).
    • CBD, mood and cognitive disorders
      • It was previously shown that a variety of psychiatric co-morbidities may occur in ASD patients, the most common one being mood disorders (Ghaziddin and Zafar, 2008).
      • Risks of THC
        • THC use may be associated with onset or aggravation of depression, bipolar disorder, mania and psychosis (Rong et al., 2017).
        • THC administration may also result in memory impairment (Ranganathan and Souza, 2006; Rong et al., 2017).
      • Benefits of CBD
        • On the other hand, CBD possesses agonistic activity at the 5-HT1A serotonin receptor and shares similar mechanisms with lithium. These pharmacological properties may indicate its potential role in the treatment of mood disorders (Rong et al., 2017).
        • Therapeutic CBD properties were investigated for cognitive deficits as well. In a preclinical study that tested the effect of CBD on cognition in an Alzheimer’s Disease mouse model (APPxPS1), chronic CBD treatment reversed the cognitive deficits without affecting anxiety-related behaviors (Cheng et al., 2014).
    • CBD and sleep disorders
      • Sleep disorders are highly prevalent among children with ASD.
      • In the general population insomnia is the most common sleep complaint, and treatment with medical cannabis may be effective, especially when the insomnia is associated with pain (Gates et al., 2014).
      • It has been claimed that long term use of cannabis may induce sleep disturbances (Gates et al., 2014). however, a case series indicated that CBD treatment may actually improve the quality of sleep in Parkinson’s disease (Chagas et al., 2014).
    • CBD and ADHD
      • ADHD is one of the most common psychiatric co-morbidities in young ASD patients (Ghaziddin and Zafar, 2008), with comorbidity rates in the range of 40-70% (Antshel et al., 2016).
      • In a pilot randomized placebo-controlled experimental study of a cannabinoid medication (an oral spray containing 1:1 ratio of THC:CBD) in adults who suffer from ADHD, there was no significant improvement in the cognitive performance, but there was a significant improvement in the hyperactivity, impulsivity and inhibition measures after the treatment with the medical cannabis (Cooper et al., 2017).
    • The role of cannabis use for social behavior
      • Risks
        • Some studies show that THC administration may lead as well to a reduction in social interaction in rats, while co-administration of CBD seems to attenuate this effect (Malone et al., 2009).
      • Benefits
        • On the other hand, in a study that tested the influence of marijuana smoking on healthy human volunteers, subjects reported retrospectively that while smoking marijuana they were happier, friendlier and calmer, responded more warmly to others, seemed to have a better understanding of their peers’ state of mind and were less likely to respond angrily or defensively. However, they had a harder time focusing and paying attention to what others said (Galanter et al., 1974).
        • CBD Use for Children
    • The administration of cannabinoids for children and adolescents suffering from ASD is a controversial legal and ethical issue (Khalil, 2012).
      • Risks
        • Those who oppose the use of medical cannabis in pediatrics claim that this treatment might harm young children and adolescents’ brain development.
      • Benefits
        • In the field of pediatric mental illnesses, CBD is sometimes used as a treatment for anxiety disorders. In a case report describing a 10-year-old girl who suffered from PTSD after being sexually abused, it was reported that CBD treatment reduced her anxiety and improved her sleep (Shannon, 2016).
  • Conclusions
    • The use of cannabinoids in general and CBD in particular in the treatment of numerous medical and mental conditions, including ASD, is growing rapidly.
    • There certainly is a big gap in the field and such studies are needed before drawing any conclusions on the potential therapeutic applications of cannabinoids in ASD.
    • Further pre-clinical and clinical studies are needed in order to examine the pros and cons of CBD and other cannabinoids in ASD, before they are established as a treatment for ASD symptoms and co-morbidities.

Recent Study Finds that Astragalin Prevents Tumor Growth

A Kaempferol-3-O-β-D-glucoside, Intervention Effect of Astragalin on Estradiol Metabolism

A recent study found that a flavonoid known as astragalin possesses a strong anti-tumor effect. High levels of a metabolite formed from the hormone estradiol have been found in tumor tissues leading researchers to search for an inhibitor to prevent estradiol from forming the metabolite. This study has found that astragalin, which is a naturally occurring substance found in a variety of plants and wine, has an effective antitumor mechanism that inhibits the formation of the metabolite.

Flavonoids Found in Buckwheat Hulls Have Antioxidant Properties

Flavonoids in common and Tartary Buckwheat hull extracts and antioxidant activity of the extracts against lipids in mayonnaise

A recent study has revealed that the various flavonoids in buckwheat hulls are a reliable source for antioxidant material. When a buckwheat hull extract was made and exposed to mayonnaise, the shelf-life of the mayonnaise was extended, likely related to the antioxidant properties. This study was able to determine the effectiveness of extracts from the common and Tartary Buckwheat hulls, as well as provide an efficient extraction method.

Researchers Look to CBD and THC for the Treatment of Chronic Pain

Efficacy and safety of cannabidiol followed by an open-label add-on of tetrahydrocannabinol for the treatment of chronic pain in patients with rheumatoid arthritis or ankylosing spondylitis: protocol for a multicentre, randomized, placebo-controlled study

Current researchers have proposed a study protocol that would expose any possible benefits of cannabidiol (CBD) and tetrahydrocannabinol (THC) for the treatment of chronic pain in patients suffering from rheumatoid arthritis (RA) and ankylosing spondylitis (AS). This new study hopes to identify how medical cannabis affects pain and cognitive function in RA and AS and provide evidence that cannabis-based pain medication is an alternative to opioids with fewer risks.
