Medical cannabis linked to long-term cognitive improvement

Improvements in function corresponded with patients’ experiencing better sleep, mood and anxiety.

MEDICAL CANNABIS
Changes in mood and anxiety were mostly evident following the use of CBD-dominant products

Patients showed significant improvements in cognitive performance, after treatment with cannabis products, according to new findings.

A new study has revealed that the use of cannabis products, particularly those that are CBD-dominant, is associated with prolonged improvements in cognitive performance.

A group of investigators from Havard University in the US, assessed executive function in medical cannabis patients prior to using cannabis and then again at three, six and twelve month intervals.

Researchers reported that patients showed improved cognitive performance within three months of treatment and these improvements continued throughout the 12-month trial period.

Improvements in function corresponded with improvements in patients’ sleep, mood, and anxiety.

Changes in mood and anxiety were mostly evident following the use of CBD-dominant products.

Patients registered in the study had very little or no prior contact with cannabis.

Authors concluded: “In a 12-month longitudinal, observational study, patients using MC [medical cannabis] for various medical conditions exhibited improved executive function and stable verbal learning and memory within the context of improvements on measures of mood, anxiety, and sleep relative to baseline. [I]improvement of clinical state over time was significantly associated with increased CBD exposure.

“Future investigations examining the impact of individual cannabinoids and age of onset of use are warranted to clarify the implications of medical cannabis use. Ultimately, for medical cannabis patients, it is imperative to understand the relationship between these variables in order to maximise the therapeutic potential of cannabis while minimising potential risk and harms.”

The study appears in the Journal of the International Neuropsychological Society.

A new study of a rare skin condition has revealed that different preparations of cannabinoids could have benefits for patients with painful Epidermolysis Bullosa (EB).

Epidermolysis Bullosa (EB) is the name of a group of rare inherited skin disorders that can cause the skin to become fragile.

It is thought to be caused by a gene mutation that makes the skin more fragile and any trauma or friction can cause painful blisters on the skin. There is currently no cure but treatment aims to prevent infection and reduce symptoms.

The study from the Netherlands and the United States analysed EB patients on five different continents who reported using cannabis preparations as a treatment for their rare skin condition.

The data is published in the Orphanet Journal of Rare Diseases. The patients reported using topical cannabinoid products in addition to inhaling cannabis flowers. They also consumed cannabis-infused edibles.

Patients were given a survey on their skin condition that focused on monitoring effects including perceived EB symptom changes, medication use, and side effects. 

Skin condition results

Results recorded that 95 percent said the topicals improved their overall skin condition symptoms with 94 percent stating their pain levels were decreased.

A further 91 percent said they had less itching and 81 reported wound healing was improved. Most of the participants at 79 percent said they had decreased their medication for their skin condition. The only side effect with a notable significance was dry mouth at 44 percent.

The authors noted that cannabis improved patient’s “perception of pain, pruritus, wound-healing, and well-being … and reduced concomitant medication use.”

Canadian study shows more women using cannabis for menopause symptoms

Researchers analysed responses from 1,500 women living across Alberta

Richardson: An app with menopause information displayed across the screen has a doctor's stethoscope resting on it.

A new study shows a large percentage of women have tried cannabis to manage their menopause symptoms.

The menopause study aimed to examine the rates and patterns of cannabis use and its perceived effectiveness in managing symptoms.

Researchers analysed responses from 1,500 women living across Alberta of which, 18 percent were in premenopausal, 33 percent were in peri-menopause and 35 percent were in post-menopause. There was also a small percentage that had either undergone a hysterectomy and or bilateral oophorectomy.

The NHS estimates that most people who experience menopause is between 45 and 55 years of age. This occurs when a person’s oestrogen levels decline. The average age for this to happen is 51. Around 1 in every 100 women enter into menopause early before 40 years old. This is referred to as premature menopause.

Common symptoms include hot flushes, night sweats, low mood, anxiety, vaginal dryness, difficulty sleeping and reduced sex drive. The average length of time that women can experience menopause is up to four years.

Menopause study results

A study from the University of Alberta in Edmonton Canada shows that one in every three women near the menopause transition uses cannabis for symptom management.

Of the women studied, roughly 33 percent reported using cannabis within the past 30 days. Out of the 499 current cannabis users, 75 percent stated they used it for medical purposes. This included the most common reason, sleep issues at 65 percent, anxiety at 45 percent and joint pain or aches at 33 percent. A further 29 percent reported they use cannabis for irritability and 25 percent for depression. Three-quarters of the current users reported that they found cannabis helpful with their symptoms.

The most common way to take cannabis was edibles with 52 percent then oils with 47 percent. Just under half of those surveyed said they got their information from internet searches while 34 percent got their information from friends.

Researchers noted that women using cannabis were more likely than non-users to report sleep issues, mood issues including depression, mood swings, irritability and anxiety along with difficulty concentrating or painful intercourse.

Katherine Babyn from the University of Alberta and the first author of the study abstract said: “Our study confirmed that a large percentage of midlife women are using cannabis for symptoms that overlap with menopause, especially those women who reported more symptoms. In addition, many of these women are claiming to get relief for their symptoms through the use of cannabis.”

Dr Stephanie Faubion, NAMS medical director said: “While we continue to learn that more women are using cannabis to help manage their menopause symptoms, further research is required to assess the safety and efficacy of cannabis for menopause symptoms management.”

The results will be presented as part of The North American Menopause Society (NAMS) annual meeting in Washington DC next week. The study was funded by an operating grant from the Canadian Institutes of Health Research (CIHR).
