Cannabis and Autism: Patient Study

Posted on by

“This morning a mother by the name of Anne brought her 21 year old autistic son to my Irvine office to be evaluated for treatment with cannabis.   He suffers from sever autism; very agitated, violent, and is unable to speak at all.  He requires 24/7 supervised care which his parents assume.   Anne described never having any total relief from the stress of taking care of him.

Anne told me she had tried everything to limit her son’s agitation.   She routinely has to give him ativan (benzodiazepine) and he takes risperidone daily which is an anti-psychotic.

In my office he was extremely agitated, was continuously banging the desk, jumping up and down and a few times even tried to hit his mother.  I could see the desperation on her face as she said “we have tried everything and need your help.”

I went on to explain that although the lack of clinical trials with cannabis and autism that many parents have successfully used it to help their children.   Personally I think the benefits clearly outweigh the risks in treating his sever agitation.   Cannabis is an excellent sedative and tends to even out patients moods.  It seems to modify the extreme highs and lows of both depression and anxiety.

Our goal is for the patient to start with some tinctures or edibles as he is not able to vaporize.   If we can get him sleeping and calm throughout the day not only will be able to function better but Anne and her husband can get some rest and relief.  We often forget about the toll that autism can take on parents and siblings.

I am confident that this is the right direction for Anne and her son.

Stay tuned for updates on patient K and her mother Anne.

I look forward to speaking with you.

respectfully,

Consequences of Cannabinoid and Monoaminergic System Disruption in a Mouse Model of Autism Spectrum Disorders

Posted on by

“Autism is a behaviorally defined neurodevelopmental disorder characterized by impairments in social interaction and communication and repetitive/stereotyped behaviors . The cause of autism is not completely understood and there is no effective cure. However, genetic and environmental factors and the interaction between genes and environment are known to play a role in Autism Spectrum Disorders (ASDs)…

Our data provides a basis for further studies in evaluating the role of the cannabinoid and monoaminergic systems in the etiology of ASDs.

It is tempting to suggest the evaluation of Δ9-THC or other cannabinoids with reduced psychoactivity in irritability, tantrums and self-injurious behavior associated with autistic individuals.

 The rationale for this novel hypothesis arises from the discovery that the endocannabinoid system is one of the most abundant physiological control systems in animals and humans.”

Would some cannabinoids ameliorate symptoms of autism?

Posted on by
“Cannabidiol (CBD) is a major nonpsychotropic constituent of cannabis sativa, which unlike the other major constituent delta9-tetrahydrocannabinol (delta9-THC), is virtually inactive at both of its central nervous system receptors. In one study, cell-based calcium mobilization and electrophysiological assays were used to identify and characterize several novel cannabinoid TRPV2 agonists in cultured rat dorsal root ganglion neurons. Among these, CBD was found to be the most robust and potent, followed by delta9-THC and cannabinol. Those cannabinoids may, accordingly, possess the ability, due to their action as TRPV2 agonists, to increase the release of both oxytocin and vasopressin enhancing the stimulation of oxytocin receptor and V1a receptors at the same time. CBD displays a plethora of other actions including anticonvulsive, sedative, hypnotic, antipsychotic, anti-inflammatory and neuroprotective properties. CBD and delta9-THC are components of drugs commercialized, in certain countries, as treatments for neuropathic pain, overactive bladder, and spasticity in patients suffering from multiple sclerosis. Thus, despite their action on oxytocin and vasopressin release, CBD and delta9-THC may help in improving symptoms of ASD by their sedative, antipsychotic, anticonvulsant and tranquilizing effects. In addition, the cannabinoid system has already been shown to be implicated in social behavior in rats.
 
The administration of cannabinoids for children and adolescents suffering from ASD is a controversial legal and ethical issue. Instead, those cannabinoids may be tested when administered to animals presenting autistic symptoms. Animal models of autistic symptoms exist especially in rodents that have their oxytocin and/or vasopressin function impaired such as mice or rats lacking the oxytocin or vasopressin gene or one of their receptors]. Whenever cannabinoids were found efficient in animal models of autism, the rationale supporting their efficacy may outweigh their legal and ethical adversities, when administered to children in the setting of randomized controlled studies.”
 

Can autism be triggered by acetaminophen activation of the endocannabinoid system?

Posted on by

Abstract

“Acetaminophen use in children has been associated with increased autism risk. Recent evidence suggests that acetaminophen’s analgesic actions result from activation of the endocannabinoid system, and activation of this system can have neuromodulatory consequences during development. This investigation was performed to determine if there is evidence to support the hypothesis that acetaminophen use can trigger autism by activation of the endocannabinoid system.”

Variation in the human cannabinoid receptor CNR1 gene modulates gaze duration for happy faces.

Posted on by

  “From an early age, humans look longer at preferred stimuli and also typically look longer at facial expressions of emotion, particularly happy faces. Atypical gaze patterns towards social stimuli are common in autism spectrum conditions (ASC). However, it is unknown whether gaze fixation patterns have any genetic basis. In this study, we tested whether variations in the cannabinoid receptor 1 (CNR1) gene are associated with gaze duration towards happy faces. This gene was selected because CNR1 is a key component of the endocannabinoid system, which is involved in processing reward, and in our previous functional magnetic resonance imaging (fMRI) study, we found that variations in CNR1 modulate the striatal response to happy (but not disgust) faces. The striatum is involved in guiding gaze to rewarding aspects of a visual scene. We aimed to validate and extend this result in another sample using a different technique (gaze tracking).

One of the key molecular systems involved in the functioning of the striatal circuit is the endocannabinoid system. It is a neuropeptidergic circuit involved in reward processing and works in tandem with the mesolimbic dopaminergic system. Expressed selectively in the brain, the cannabinoid receptor 1 (CNR1) is the best-studied molecule of this system.

This finding suggests a role for CNR1 in social reward processing and could have significance for clinical conditions such ASC, which are marked by a deficit in social reward processing as well as atypical responses to facial expressions of emotion.”

Variations in the human cannabinoid receptor (CNR1) gene modulate striatal responses to happy faces.

Posted on by

Abstract

“Happy facial expressions are innate social rewards and evoke a response in the striatum, a region known for its role in reward processing in rats, primates and humans. The cannabinoid receptor 1 (CNR1) is the best-characterized molecule of the endocannabinoid system, involved in processing rewards. We hypothesized that genetic variation in human CNR1 gene would predict differences in the striatal response to happy faces. In a 3T functional magnetic resonance imaging (fMRI) scanning study on 19 Caucasian volunteers, we report that four single nucleotide polymorphisms (SNPs) in the CNR1 locus modulate differential striatal response to happy but not to disgust faces. This suggests a role for the variations of the CNR1 gene in underlying social reward responsivity. Future studies should aim to replicate this finding with a balanced design in a larger sample, but these preliminary results suggest neural responsivity to emotional and socially rewarding stimuli varies as a function of CNR1 genotype. This has implications for medical conditions involving hypo-responsivity to emotional and social stimuli, such as autism.”

[Cannabinoids in the control of pain].

Posted on by

Abstract

“Hemp (Cannabis sativa L.) has been used since remotes ages as a herbal remedy. Only recently the medical community highlighted the pharmacological scientific bases of its effects. The most important active principle, Delta-9-tetrahydrocannabinol, was identified in the second half of the last century, and subsequently two receptors were identified and cloned: CB1 that is primarily present in the central nervous system, and CB2 that is present on the cells of the immune system. Endogenous ligands, called endocannabinoids, were characterized. The anandamide was the first one to be discovered. The effectiveness of the cannabinoids in the treatment of nausea and vomit due to anti-neoplastic chemotherapy and in the wasting-syndrome during AIDS is recognized. Moreover, the cannabinoids are analgesic, and their activity is comparable to the weak opioids. Furthermore, parallels exist between opioid and cannabinoid receptors, and evidence is accumulating that the two systems sometimes may operate synergistically. The interest of the pharmaceutical companies led to the production of various drugs, whether synthetic or natural derived. The good ratio between the polyunsatured fatty acids omega-3 and omega-6 of the oil of Cannabis seeds led to reduction of the phlogosis and an improvement of the pain symptoms in patients with chronic musculo-skeletal inflammation.”

An analgesic role for cannabinoids.

Posted on by

Abstract

“Cannabinoids have significant analgesic properties in animal models, particularly for chronic pain states, but there are few human studies. An endogenous cannabinoid system, with specific receptors and transmitters, has recently been discovered. This discovery has led pharmacologists to explore the potential of synthetic cannabinoids to selectively target chronic pain disorders without producing the side effects associated with cannabis. Well-controlled clinical trials on cannabinoids, and cannabinoid delivery systems, are now required.”

Reassessment of the role of cannabinoids in the management of pain.

Posted on by

“The aim of this article is to assess the role of cannabinoids in the treatment of acute and chronic pain in humans.

 …to date there is increasing evidence that cannabinoids are safe and effective for refractory chronic pain conditions including neuropathic pain associated with multiple sclerosis, rheumatoid arthritis, and peripheral neuropathy associated with HIV/AIDS.

SUMMARY:

The precise role of cannabinoids in pain treatment still needs further evaluation. Cannabinoid compounds may be more effective in the context of chronic neuropathic pain than for the management of acute pain.”
