As I have written elsewhere on this site, I was treated surgically for a large, subarachnoid cyst (in the velum interpositum) in the summer of 2017. I had been experiencing severe amnesia. The operation was successful in that my memory improved. The surgeon warned of the risk of "convulsions" in the surgical plan, and over the following year or more, I had ongoing occurrences of memory loss. Last December, my surgeon started me on epilepsy medication, as a treatment for these memory failures. From my reading, I took it that I had Transient Epileptic Amnesia. Today, I went for my latest check-up and to get my next prescription of epilepsy (Vimpat aka Lacosamide), and he told me that in fact I have Transient Global Amnesia. (TGA)
So far so good, but I immediately checked the medical literature on TGA, and the first paper I read (published in QJM) says that TGA doesn't respond to anti-epilepsy drugs. https://academic.oup.com/qjmed/article/107/11/915/1512956
I thought Lacosamide is an anti-epilepsy drug. If TGA doesn't respond to it, why has the doc prescribed it? Vimpat is a non-generic drug and it's really expensive.
Does anyone have a similar situation or knowledge about TGA or its treatment?
