Temporal lobe epilepsy causes repeated seizures and often interferes with memory and thinking. New research now suggests that this condition is also tied to early aging in certain brain cells. Scientists at Georgetown University Medical Center report that eliminating these aging cells in mice led to fewer seizures, better memory, and protection against epilepsy in some animals. The aging cells were removed using both genetic approaches and drug-based treatments.
The National Institutes of Health (NIH)-funded study was published on December 22 in the journal Annals of Neurology.
A New Approach for Drug Resistant Epilepsy
"A third of individuals living with epilepsy don't achieve freedom from seizures with current medications." says senior author Patrick A. Forcelli, Ph.D., professor and chair of Georgetown School of Medicine's Department of Pharmacology & Physiology and the Jerome H. Fleisch & Marlene L. Cohen Endowed Professor of Pharmacology. "Our hope is that senotherapy, which involves using medications to remove senescent, or aging cells, could potentially minimize the need for surgery and/or improve outcomes after surgery."
Temporal lobe epilepsy (TLE) can arise from many underlying causes. These include head injuries related to trauma or stroke, infections such as meningitis, brain tumors, abnormal blood vessel structures, and inherited genetic conditions. TLE is the most common form of epilepsy that does not respond well to medication and affects roughly 40% of people with epilepsy. Mouse Experiments Show Reduced Seizures and Memory Gains
Based on the findings in human tissue, the team investigated whether a similar buildup of aging cells occurred in a mouse model designed to mimic TLE. Within two weeks after the brain injury that initiated epilepsy in the mice, the researchers detected clear increases in markers of cellular aging at both the gene and protein levels.
When treatments were used to remove the aging cells, the effects were substantial. The number of senescent cells dropped by about 50%. The treated mice performed normally on maze-based memory tests, experienced fewer seizures, and about one-third were completely protected from developing epilepsy.
Repurposed Drugs With Known Safety Profiles
The drug treatment tested in the mice combined dasatinib [see NOTE below] and quercetin. Dasatinib is a targeted therapy currently used to treat leukemia. Quercetin is a plant flavonoid found in fruits, vegetables, tea, and wine that can act as a powerful antioxidant and have anti-inflammatory properties. This drug combination has been widely used in animal studies to eliminate senescent cells across several disease models.
The researchers selected these drugs in part because both are already being evaluated in early phase clinical trials for other conditions. Forcelli also notes that dasatinib is FDA approved for a form of leukemia, meaning its safety profile is well established. This could allow a faster transition toward clinical testing in people with epilepsy.
Broader Implications for Brain Aging and Disease
The study's first co-authors Tahiyana Khan, Ph.D. and David J. McFall, both trainees in Forcelli's lab, note that aging of glial cells has recently been linked to both normal aging and neurodegenerative conditions such as Alzheimer's disease. This connection is another focus of their ongoing research.
"We have ongoing studies using other repurposed drugs that can impact senescence as well as studies in other rodent models of epilepsy. We would like to understand the critical windows for intervention in epilepsy, and the hope is that these studies will lead to clinically useful treatments," says Forcelli.

NOTE: Many people are using theaflavins, extracted from black tea, in place of the prescription drug dasatinib. Theaflans have senolytic functions that compliment those of quercetin, and don't have the side-effects of dasatinib. ALSO: Fisetin, found in strawberries and available in supplement form (at much larger doses than found in a typical bowl of strawberries) is an even stronger senolytic than quercetin.
I've been taking quercetin for years now as part of my daily supplements.
Same. We've learned a lot over the past few years. I also take NAC daily as well.
Do you have any of the common side effects from NAC?
Nausea and vomiting Diarrhea Stomach upset or abdominal pain Heartburn Constipation Fatigue Skin rash or itching
Never once had any of that happen with NAC and I've been using at least 500mg/day for years.
None
I use it daily, and have none of the side effects you mentioned.
NAC is truly a wonderful supplement.
There is a fungal detox utilizing NAC too, along with Blackseed Oil and Oil of Oregano
Nac, quercetin, zinc and vitamin d. If you add Acetyl L-Carnitine HCL with the Nac, it reduces the urge to smoke.
Concentrated being the key. "Why can't I just eat the foods containing these?" Because you can't realistically eat enough to get the therapeutic amounts in a single day, some of these concentrations would require you to eat anywhere from ten to a hundred pounds of the raw food in a single day. This is also a big reason why they often end up being made by synthetic means in order to be economical and not have tonnes of food waste as a byproduct. This page has a table showing the foods that have fisetin and you can see that even the most dense of them has very little in it: https://lifespan.io/topic/fisetin-benefits-side-effects/
Then there's figuring out the dosage, seems that studies find that quite a number of supplements thought to be ineffective were simply underdosed. Take nattokinase for example, most bottles will tell you 4000 FU per day while the studies that had success with reducing LDL and even reversing arterial plaque didn't find effects until between 6-10k per day. I myself didn't see anything at 4k then after reading the studies went to 8k and after 4 weeks retested my lipids and saw a 30 point drop in both LDL and triglycerides despite changing nothing else in my diet.
Before you go on fisetin you may want to watch this video and do a bit more research on how to dose and cycle it: https://www.youtube.com/watch?v=plT7vWHbtQs
Turns out there is a use for senescent cells in our body, while it is problem when they build up wiping them all out can cause other issues.
I have taken Life Extension Foundation's Senolytic Activator occasionally for a few years and have had remarkable good results. Clearer thinking, better memory, better aerobic condition and a general feeling of youthfulness were the result.
When you take it it tags cells to be removed and then it takes a week or so to get the cleaning out taken care of. You might feel off or a little like having a mild cold when the cleaning out is happening, especially the first time.
The Life Extension Foundation has made dosing simple and convenient. Highly recommended. https://www.lifeextension.com/vitamins-supplements/item02301/senolytic-activator Currently on sale for $18.23.
Thanks fren! I have a relative that has epilepsy and I passed it along for them to look into!
I've been taking Fisetin for a few months.
Vanity reasons - there's some anecdotal evidence that it can reverse grey hair. As someone in IT, which tends to be very ageist, this would be helpful for my career.
Have a haircut this morning, hopefully will see some reduction. Main source on YouTube said it took 8 months so maybe too early to tell.
Premature graying is also an early symptom of copper insufficiency. Whether or not you can reverse the greying depends on how long the hair follicles have been gray for.
It's probably not premature in my case. I probably should be greyer but my mom's family tends to not go fully grey until 70s/80s - I'm just late 50s and just have some highlights on the sides for now.
But even appearing late 40s is an impediment in this job market at least in IT.
That said, it probably wouldn't hurt to try some cu supplementation...
Yeah IT is a shitshow like that, meanwhile in other fields if you don't have at least a little grey then you're not taken seriously as people assume that you're inexperienced if you look too young. I remember a guy even saying that he uses touch of grey as he found it got him bigger raises and more promotions.
