Transient Epileptic Amnesia

QuestionsTransient Epileptic Amnesia
Anonymous asked 8 years ago
Dear Dr. Dean,

I read with interest your article on seizures.  I am 69, and started having partial seizures about 5 years ago–pretty much daily, 1-4 seizures that manifested as extreme deja vu (seizures confirmed with a stay in the hospital).

I tried drugs, but they didn’t stop the seizures and made me very ill–nausea, etc, so quit taking.  I take no other drugs.

I also started having transient epileptic amnesia (TEA), about once a month for maybe the last 3 years.  When I went on a high fat/low carb ketogenic type diet two years ago, my partial seizures went away.  However, I still continue to have the TEA episodes.

I am on a nutritional balancing program (NB) where I do hair analysis (also read your article on hair analysis) every 3 months to determine supplementation.   Do you have any advice about Transient Epileptic Amnesia?”

Thanks,

Hello,
Transient epileptic amnesia is a rare condition for which no established treatment has been found. Consider my suggestions as educated guesses.
If you’ve read much of my stuff, you probably know that I tend to be a big proponent of the anti-epileptic drug gabapentin, as a sleep enhancer. Gabapentin actually improves normal sleep, by enhancing all four phases of sleep.1 I’m not sure what anti-epileptic drugs you’ve taken, but if you haven’t taken gabapentin, I would recommend adding it to your present regimen. You’ll benefit from the anti-seizure effects of Gabapentin, as well as its sleep-enhancing properties. Gabapentin’s cognitive effects in those with seizure disorders appear to be at least neutral2—and may even be positive.3 In any case, the sleep-enhancing effects of Gabapentin should be beneficial—to say nothing of its anti-seizure effects.
Considering your current situation, another anti-epileptic medication to consider for daytime use is Keppra, (Levetiracetam). Levetiracetam is a pyrrolidone derivative structurally similar to the nootropic prototype, Piracetam (Fig.). In fact, Levetiracetam was initially intended as a cognitive enhancer, with the hope of finding a cognitive-enhancing drug even more effective than Piracetam. Piracetam was known to significantly improve learning and memory; in contrast, Levetiracetam was initially determined to have less effect as a cognitive enhancer, but was more active in preventing seizures.4
Nevertheless, a number of subsequent studies indicate that in addition to its anti-epileptic properties, Levetiracetam also appears to be “rising to the occasion” as a cognitive enhancer. It improves reaction time, tapping rate and memory;5 improves cognition/behavior in children;6, 7 improves executive functions, psychomotor speed, concentration and remote memory;8 and increases quality-of-life scores.9, 10 Levetiracetam has also improved a range of cognitive abilities, including visual short-term memory;11 prospective memory, working memory and motor functions;12, 13 psychomotor speed and concentration;14 fluid intelligence;15 and improvements on the Mini-Mental State Examination.16, 17 Levetiracetam also improved health-related quality of life over a four-year period,18 improved cognition in patients with medically-refractive partial seizures,19 improved cognitive outcomes in patients with intracranial hemorrhage,20 and improved verbal memory in high-grade glioma patients.21
Dosage
Sleep-inducing dosages of Gabapentin usually range from 600-800 mg at night, although a few patients get by on as little as 100mg, and some require heroic dosages as high as 3200 mg. For Levetiracetam, the initial dose is 1,000 mg/day, given as 500 mg twice daily, with additional dosage increments up to a maximum recommended daily dose of 3,000 mg—although doses higher than 3,000 mg/day have been used in open-label studies for periods of six months and longer without adverse effects.
Let me know how you do,
Ward Dean, MD
