Eicosapentaenoic acid improves cognitionA Compared Study of Eicosapentaenoic Acid and Docosahexaenoic Acid in Improving Seizure-Induced Cognitive Deficiency in a Pentylenetetrazol-Kindling Young Mice Model.
Directly impacts seizure cognition
We investigated the potential effects of eicosapentaenoic acid (EPA) on cognitive impairment triggered by seizures, particularly in a model involving young mice. Our focus was on understanding how EPA, when compared to docosahexaenoic acid (DHA), could play a role in mitigating cognitive deficiencies related to epilepsy.
For our study, we fed young mice either a DHA-rich or EPA-rich diet for 21 days while exposing them to pentylenetetrazol (PTZ) injections to induce seizures. Through this approach, we observed that both EPA and DHA provided some improvement against seizure-related cognitive decline; however, EPA stood out with more significant benefits, particularly in maintaining iron balance in the brain.
We also found that both fatty acids helped balance neurotransmitter levels and reduced indicators of ferroptosis—a form of cell death linked to epilepsy. Notably, EPA was more effective in this aspect due to its ability to enhance certain signaling pathways in the brain. This suggests that incorporating EPA might be advantageous for managing cognitive impairments associated with seizures in children.

Eicosapentaenoic acid aids epilepsyDHA and EPA Prevent Seizure and Depression-Like Behavior by Inhibiting Ferroptosis and Neuroinflammation via Different Mode-of-Actions in a Pentylenetetrazole-Induced Kindling Model in Mice.
Directly addresses EPA’s effects
We explored the effects of eicosapentaenoic acid (EPA) on epilepsy, particularly how it influences seizures and depression-like behavior in mice subjected to pentylenetetrazol (PTZ) induced seizures. Our study showed that administering EPA significantly reduced both seizure activity and depressive symptoms, indicating its potential as an anticonvulsant agent.
In our tests, we found that EPA outperformed docosahexaenoic acid (DHA) in these areas. We looked deeper to understand why EPA was more effective, discovering that it helps shift microglial cells toward a protective M2 state while inhibiting the harmful M1 state. This shift is linked to lower iron levels in the brain, likely due to EPA’s stronger activation of a protective pathway known as Nrf2.
Additionally, we noticed both EPA and DHA can inhibit inflammation related to a specific cellular process called NLRP3 inflammasome activation, but they do this in different ways. This means that while both fatty acids have benefits, EPA may provide a stronger effect due to its unique mechanisms.
Overall, our findings suggest that both EPA and DHA can relieve seizure and depression-like behaviors, but EPA stands out in effectiveness and its underlying functions.

Omega-3 reduces epilepsy seizuresThe effect of omega-3 fatty acid supplementation on seizure frequency in individuals with epilepsy: a systematic review and meta-analysis.
Relevant but lacks specificity
We systematically reviewed and analyzed several studies to understand how omega-3 fatty acids, particularly eicosapentaenoic acid, can influence seizure frequency in people living with epilepsy. By searching through major medical databases and including various trials conducted up to October 2020, we aimed to provide clear insights into this subject.
Our analysis focused on various aspects such as the intervention duration and dosage of omega-3 supplementation. The studies included revealed that treatment with omega-3 fatty acids, particularly dosages around 1500 mg or less per day, showed significant reductions in seizure frequency. Notably, those who participated in studies lasting more than 16 weeks also experienced more substantial improvements.
Interestingly, we found that adults benefitted more from omega-3 supplementation compared to children with epilepsy. This highlights the need for tailored treatments based on age groups. Overall, our findings suggest that incorporating omega-3 fatty acids could be a valuable strategy in managing epilepsy symptoms effectively.

We investigated how plasma fatty acid levels affect individuals with drug-resistant epilepsy (DRE) in Sudan. The study included 83 patients and 31 healthy controls, allowing us to compare their blood fatty acid compositions.
Our findings revealed that patients with DRE had higher levels of certain saturated and monounsaturated fatty acids compared to the healthy group. However, they showed lower levels of both omega-6 and omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are known for their potential benefits in managing seizures.
Interestingly, we also assessed the activity levels of important enzymes that help modify fatty acids in the body. These enzyme activities were found to be abnormal in the DRE patients, suggesting a metabolic disturbance related to fatty acids.
While the study highlights a clear fatty acid imbalance in DRE patients, it does not isolate the effects of eicosapentaenoic acid alone on seizure frequency. Therefore, we can't definitively say how effective EPA is in treating epilepsy. However, our findings indicate that incorporating omega-3 fatty acids into treatment plans could be beneficial and warrant further investigation.

DHA and EPA mitigate epileptic depressionDHA and EPA Alleviate Epileptic Depression in PTZ-Treated Young Mice Model by Inhibiting Neuroinflammation through Regulating Microglial M2 Polarization and Improving Mitochondrial Metabolism.
Study highlights EPA's effectiveness
We explored the effects of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) on depression associated with epilepsy in young mice. Using a well-structured approach, we treated three-week-old mice with a diet rich in either DHA or EPA for 21 days, followed by a series of pentylenetetrazole (PTZ) injections to induce depressive symptoms.
Our findings revealed that EPA was particularly effective in alleviating these symptoms compared to DHA. Both fatty acids significantly reduced neuronal damage in the hippocampus and improved myelin integrity, indicating potential protective effects on brain health.
Delving deeper, we discovered that DHA and EPA reduced neuroinflammation by helping microglial cells switch to a protective M2 phenotype. Moreover, both compounds lowered oxidative stress levels and enhanced mitochondrial function, which plays a crucial role in energy production and overall cellular health.
These results suggest that incorporating DHA and EPA into the diet may serve as an effective strategy to combat depression in children dealing with epilepsy, with EPA emerging as the more beneficial option.
