SciTechDaily has an artilce about DNA in Europe from 5000 BC to now-ish. This is, I think, the ceramic Neolithic. It'll span the rise and fall of Cucuteni, and then the steppe invasion.

That is rather telling me that immunity had side-effects. Once the disease was defeated, the genes lingered... as allergens. Allergens, like STC're also saying gives us Alzheimer's.
