Analysis of the week's best papers, sponsored byĀ CV Sciences
In healthy adult, six weeks of 700 milligrams of PEA per day significantly increased scores on a memory test as well as levels of BDNF (a key brain growth factor for neural plasticity)
Formulated Palmitoylethanolamide Supplementation Improves Parameters of Cognitive Function and BDNF Levels in Young, Healthy Adults: A Randomised Cross-Over Trial
https://pubmed.ncbi.nlm.nih.gov/38398813/
Want to be the smartest person in the room? Want to memorize Ļ to a few hundred digits? Cognition got you down?Ā Try PEA!
I might have missed my calling writing ads for used car lots ā but this PEA study sells itself. With 39 participants in this double-blind placebo-controlled crossover trial, for six weeks the researchers gave them 700 mg of Levagen+ PEA (the same source as in ourĀ Relief product) per day. Before starting the trial, the participants gave serum samples and took a battery of cognition tests. After the six weeks, the ones gettingĀ PEA scored significantly higher on the memory testĀ than those getting the placebo, though no changes to attention or psychomotor speed. In addition, the PEA caused their blood to haveĀ increased levels of BDNFĀ (brain-derived neurotrophic factor ā a key protein for brain plasticity). As the researchers state, āthese findings lay the foundations for formulatedĀ PEA (Levagen+Ā®) to be considered an effective nootropic supplementĀ that can be used by populations to support academic study and by the wider general public to improve cognition.ā
To see all the research ever done on this endocannabinoid-like molecule, seeĀ the PEA page of CVResearch.info.
In people with brain fog after COVID, PEA & luteolin (an antioxidant flavonoid often paired with PEA) caused significant improvement to their scores & 80% of the patients reported improvements
Co-ultraPEALut in Subjective Cognitive Impairment Following SARS-CoV-2 Infection: An Exploratory Retrospective Study
https://www.preprints.org/manuscript/202402.0544/v1
In this retrospective study, the researchers compared controls with brain fog from long COVID against 26 similar patients who also took a combination of 700 mg of PEA + 70 mg of luteolin (an antioxidant flavonoid often paired with PEA) for at least two months. From their first neurological evaluation,Ā the patients taking PEA+lut showed significant improvements, especially in their memory and cognition scores. Fatigue scores also improved, although not to statistical significance. Out of these 26 patients,Ā 16 reported a reduction of their symptoms, 5 reported a complete remission, 4 reported that they remained stable, and only one reported worsening symptoms. Interestingly, the PEA+lut patients who were also getting corticosteroids did no better than those who werenāt getting them (except for fatigue). The researchers guess that the benefits of the PEA+lut powerhouse is due to its anti-inflammatory properties against the neuroinflammation of long COVID.
In patients with insomnia, cannabis medicine caused an improvement in sleep quality
UK Medical Cannabis Registry: Assessment of clinical outcomes in patients with insomnia
https://pubmed.ncbi.nlm.nih.gov/38337193/
Another helpful study from theĀ UK Medical Cannabis Registry. In a case series of 61 patients with insomnia, they followed them for up to six months after the initiation of cannabinoid-based medicines. They were prescribed CBD or THC oil, CBD or THC flower, or a combination (see theĀ table here). AboutĀ half the participants experienced clinically significant improvementsĀ on their SleepāQuality Scale, their Generalized Anxiety Disorder score, and/or their quality-of-life scores (the EQ-5D-5L, covering mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). This lines up with all the anecdotes saying that while cannabinoids donāt help everyoneās sleep, for a large subset of people, they make a game-changing difference.

https://pubmed.ncbi.nlm.nih.gov/38397346/
āThirty-one patients with a primary diagnosis of neuropediatric, oncologic, metabolic, and cardiologic categories were included. The indications we identified were spasticity, pain, restlessness, anxiety, loss of appetite, epilepsy, and paresis. Certain aspects of quality of life were improved for 20 of 31 patients (64.5%). For nine patients (29%), no improvement was detected. No conclusions could be drawn for two patients (6.5%). Adverse events were reported for six of the thirty-one patients (19.4%). These were graded as mild, including symptoms such as restlessness, nausea, and behavioral issues. We detected no clinically relevant interactions with other medications.ā

āThe top five reasons for using CBD were self-reported stress (65.3%), sleep problems (51.7%), overall improvement in well-being (52.5%), improved mood (44.9%), and anxiety relief (40.9%). Our findings suggest that individuals with psychiatric disorders and those taking psychotropic medications are more likely to use CBD to relieve stress and anxiety. Overall, nearly 70% of the individuals found CBD products to be effective.ā

An evergreen note on reading restricted papers:
First stop for seeing if thereās a free version of a paper, use the Google Scholar Chrome extension (Mac version), Google Scholar itself or try ResearchGate.
Three other helpful browser extensions are: Unpaywall, Open Access Button & PaperPanda
For the infamous backdoor, use Sci-Hub ā the pirated papers repository (Chrome extension here). This works better for older paper than the stuff that just came out.
Finally, email the author. Theyāre almost always happy to oblige because, thanks to the predatory academic publishing system, they donāt make a dollar off of their papers.

āParticipants prescribed THC-dominant MC products were statistically more likely to be younger, male, and to prefer inhaled routes of administration than participants using CBD-dominant products who were older, female, and preferred oral routes of administration. Pain and mental health were the most common reasons for all types of prescribed MC, but were more likely to be treated with THC than CBD despite the significantly higher risk of mild to severe drowsiness, dry mouth and eye irritation. Consumer reported effectiveness of prescribed MC was very positive, particularly for THC-containing products. Consumers on opioids and antipsychotics were statistically more likely to be prescribed THC-containing products than products containing CBD only, despite the greater risk of impairment.ā

More cannabis stores were located in the 'most socially deprived' or 'socially deprived' neighbourhoods (37.2% and 22.1%, respectively), characterized by a higher proportion of residents who live alone, are unmarried, or in single-parent families.ā

āBoth baseline- and persistent cannabis use predicted enduringly higher levels of diminished expression over a 10-year period after the first episode of psychosis, compared to non-use. There was no significant link between cannabis use and apathy, and no link to either dimensions of negative symptoms in bipolar disorders, suggesting that disorders on the more severe end of the psychosis spectrum are more vulnerable to the effects of cannabis. The differences in association between cannabis use and the two negative symptom dimensions show that they respond differently to cannabis exposure, which may indicate that the underlying pathophysiological mechanisms of diminished expression and apathy are divergent.ā

PS: For todayās swinging guitar of Argentina, Oscar AlemĆ”nās āHombre Mio the Master of Swing Guitarā. In 1919, after being orphaned at the age of 10, AlemĆ”n supported himself by playing music on the street & bought a guitar for playing at parties. By 1925, he was playing in Buenos Aires, soon followed by a world tour. He decided to stay in Madrid where he discovered American jazz. Then Josephine Baker hired him to lead her band at the CafĆ© de Paris. He was a great friend of Django Reinhardt, but indeed, despite being one of the best swing guitar players of the ā30s, the gypsy jazz of Django would always overshadow AlemĆ”nās work. But he toured Europe with Louis Armstrong & Duke Ellington before returning to local fame in Argentina. You can see the documentary āOscar Aleman: Vida Con Swingā about his life.
