I Have a little experience of Vivitonin. My Irish Setter bitch was put on it in 1994, after she had what I thought was a minor stroke. In hindsight I think it was probably a transient ischaemic attack, she made a good recovery on Vivitonin and so stupidly, I stopped the tablets. She then had another TIA, and the vet said once the Vivitonin is started the dog should remain on it permanently. Holly was 12 years old at the time and she was on the medication for two years. She was eventually put to sleep when she continued to have TIA's on the drug at aged 14 years.
There are similar drugs available in human medicine, I'll check the BNF at work later today, and post again.

Edited to add, Vivitonin improves the blood suppy to the brain.
