PEA was found to reduce pain scores relative to comparators in a pooled estimate, with a standard mean difference of 1.68 (95% CI 1.05 to 2.31, p = 0.00001).
Several studies reported additional benefits of PEA for quality of life and functional status, and no major side effects were attributed to PEA in any study.
The results of this systematic review and meta-analysis suggest that PEA is an effective and well-tolerated treatment for chronic pain.
2Agitation managementMeta-AnalyseCited 2×n=2,503 · very large study2025
This study underscores the efficacy and tolerability of several pharmacotherapies in managing agitation among children and adults with ASD or ID.
Bahji A et al. · Journal of psychopharmacology (Oxford, England) (2025)
Importantly, these treatments were generally well-tolerated, with no significant increase in all-cause dropouts compared to placebo, highlighting their suitability for clinical use in managing agitation in individuals with ASD or ID.
This study underscores the efficacy and tolerability of several pharmacotherapies in managing agitation among children and adults with ASD or ID.
Our findings provide robust evidence that specific treatments, such as arbaclofen, risperidone plus buspirone and omega-3 fatty acids, are both effective and well-tolerated, offering valuable therapeutic options for clinicians.

Palmitoylethanolamide is a promising alternative to chronic opioid analgesics, potentially reducing the risk of opioid abuse and dependency.
5Pain intensity reductionMeta-AnalyseCited 10×n=742 · large study2024
Overall, these results confirm the clinically relevant and time-depended pain-relieving effect of micron-size PEA and therefore the advantage of an extended treatment, especially in patient with incomplete pain management.

These two obtained scores corresponded to a 35.1% pain intensity reduction within the first month, followed by a further 35.4% during the second month.
The meta-analysis showed a statistically and clinically significant pain intensity reduction after 60 days of micron-size PEA supplementation, compared to 30 days (1.36 points, p < 0.01).
The secondary analysis revealed a weighted NRS/VAS score decrease of 2.08 points within the first month of treatment.
PEA may be a useful treatment for pain and is generally well tolerated in research populations.
Artukoglu BB et al. · Pain physician (2017)
PEA was associated with significantly greater pain reduction compared to inactive control conditions (WMD = 2.03, 95% CI: 1.19 - 2.87, z = 4.75, P < 0.001).
All-cause dropout was non-significantly reduced in the PEA group compared to inactive control conditions (RR = 0.36, 95% CI: 0.10 - 1.26, z = -1.60, P = 0.11).
PEA may be a useful treatment for pain and is generally well tolerated in research populations.
Treatments such as PRP and calcium chelators demonstrated significant improvements on OFS, whereas olfactory training and corticosteroids did not show notable efficacy for COVID-19 associated olfactory dysfunction.

9Brain fog symptoms improvementSystematische ÜbersichtCited 19×n=17 · very small study2024
Two studies showed that the use of Palmitoylethanolamide and Luteolin (PEA-LUT) improved cognitive impairment.
Gorenshtein A et al. · Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology (2024)
Noninvasive brain stimulation and hyperbaric oxygen therapy showed promising results in the treatment of brain fog symptoms caused by long-COVID, with improved perfusion and cortical excitability.
Furthermore, both rehabilitation strategies and PEA-LUT administration have been associated with improvements in symptoms of brain fog.
Future studies should explore combinations of interventions and include longer follow-up periods to assess the long-term effects of these treatments.

Very low certainty evidence suggests that adverse events are common (prevalence: 26.0%; 95% CI 13.2% to 41.2%) among users of medical cannabis for chronic pain, particularly any psychiatric adverse events (prevalence: 13.5%; 95% CI 2.6% to 30.6%).

Potential neurobiological underpinnings include modulation of immune response, neuroinflammation, neurotrophy, apoptosis, neurogenesis, neuroplasticity, neurodegeneration, mitochondrial function, and microbiota activity, possibly through peroxisome proliferator-activated receptor-α (PPAR-α) activation.

Evidence was collected from highly biased, short-term, heterogenous studies mainly focused on BMS-related pain, with scarce data on quality of life, psychologic status, dysgeusia, and xerostomia.
Long-term effectiveness of nonpharmacologic treatments should be further investigated, with a more rigorous, bias-proof study design.
In this review the large number of studies on the benefits derived from oral administration of micronized and highly bioavailable forms of Palmitoylethanolamide is discussed, with special reference to neuroinflammatory disorders.
Petrosino S et al. · International journal of molecular sciences (2020)
It has been shown that the regulation of non-neuronal cells-and therefore the control of neuroinflammation-depends on the local "on demand" synthesis of the endogenous lipid amide Palmitoylethanolamide and related endocannabinoids.
When the balance between synthesis and degradation of this bioactive lipid mediator is disrupted in favor of reduced synthesis and/or increased degradation, the behavior of non-neuronal cells may not be appropriately regulated and neuroinflammation exceeds the physiological boundaries.

The magnitude of reduction equals 1.04 points every 2 weeks with a 35% response variance explained by the linear model.
In contrast, in the control group pain, reduction intensity equals 0.20 points every 2 weeks with only 1% of the total variance explained by the regression.

The intervention group showed significantly greater improvement in olfactory threshold, discrimination, and identification scores compared to controls (p=0.0001).
Overall, 92% of patients in the intervention group improved versus 42% of controls.
Magnitude of recovery was significantly greater in the intervention group versus control (12.8 + 8.2 versus mean 3.2 + 3), with >10-fold higher prevalence of anosmia in control versus intervention groups at the 90-day endpoint.
