Hello, my name is John, my wife Freda was diagnosed with Dementia 2 years ago which has deteriorated gradually, but recently because of isolating due to Covid has become noticeably worse, has anyone heard of or experience of Lions Mane extract, there are claims that it helps with the enhancement in the production of nerve growth factor, so improving memory. Currently she is prescribed Memantine 20mg, I spoke to the Memory clinic to see if her medication could be adjusted to compensate for the deterioration, but they say that there is nothing further to help.
