About two months after vaccination patient completely lost ability to remember any new information. At that time we did not connect this with vaccination. On 12/12/2021 patient received Dose 3 of :Moderna (booster), lot 60H21A In early 2022 we started tests at clinic. MRI scans did not show any damage of patient’s brain. In May 2022 patient received wrong (as was shown later) diagnosis of Alzheimer, by Dr of clinic, and started treatment with Donepezil. In Summer 2023 Alzheimer diagnosis was excluded by lumbar puncture at clinic. MRI performed in Sep 2023 have shown about 40% reduction of gray matter volume. doctor gave diagnosis of CorticoBasal degeneration. At the end of 2023, analyzing my notes, I came to conclusion that patient’s memory was switched off in 2021 due to Moderna vaccination. In addition to brain atrophy, by 2023 patient also developed severe walking difficulties. The brain atrophy may be the result of wrong treatment with donepezil, while she did not have Alzheimer (there are several scientific papers that show that Donepezil accelerate neurodegeneration in people who do not have Alzheimer). Patient is now completely disables and required 24/7 caregiver support. In 2024 we have followed with clinical trial and study, and with 3-days detailed study at clinic. These studies did not add any more clarity to the reasons of patient’s conditions. The doctors at numerous clinics were informed about my conclusion that patient’s memory was switched off by mRNA vaccination, but neither deny no confirm this conclusion. I have also conveyed to clinic doctors that the fact that patient’s memory was switched off so fast makes patient a new “study Patient”* a person with a known reason that affected her memory mechanism. Genetics, molecular, and other studies of patient may give answers to memory mechanisms questions potentially bringing the Prize to successful researchers. Finding and synthesizing a suitable molecular substance that could switch memory back on would bring a second Prize to courageous scientists. * Different study Patient person whose hippocampus was surgically destroyed and he lost ability to remember new things numerous results on the memory mechanism originated from patient studies.
