An unusual case of reduction in the symptoms of Alzheimer disease (AD) is described as a new finding showing unexpected retention of memory. Presenting with an NHS consultant diagnosis of vascular dementia in 2016 with no formal treatment given, the patient, who was known to the author AC, started taking a specific food additive and supplement mixture in July 2017. This was associated with some reduction of previous confirmed vascular dementia-related psychotic behavior but no improvement in his seriously reduced cognition. In October 2017 the consultant diagnosis was changed to vascular dementia with AD and medication with donepezil was commenced. One month later an enhanced food additive mixture was also commenced in addition to donepezil. Rapid improvement in cognition followed with apparent return of memory to a surprising extent over a period of four months with improvement continuing to date.
