There are certainly theoretical reasons why it might help. There is definitely a link between AD and blood sugar. Having diabetes doubles your risk of AD. The brain regions hit first and worst in AD have the highest levels of aerobic glycolysis (in which cells take glucose only through glycolysis and not oxidative phosphorylation, despite the presence of adequate oxygen). To the extent a keto diet can reduce resting blood sugar levels and improve insulin sensitivity, there is good reason to think it is a candidate to slow AD.
