The whole point of ECT is to spur neurogenesis.
This can also be accomplished with magnesium (l-threonate) and l-theanine before bed.

To someone with no knowledge about your claim (me included), it seems like an extraordinary claim with no extraordinary evidence, or really any information at all, to back it up.
To someone with knowledge of your claim, assuming it is a true one, it adds nothing to what they already know. So maybe it's obvious to an expert, but then they don't need to be told.

The thing with most nootropics though is that the effects aren't big, the side effects of chronic usage aren't well known, and the basics such as exercise/sleep have a bigger effect.
Out of the two mentioned above (magnesium and l-theanine) - many people are deficient in magnesium due to modern diet, and there's some evidence that l-theanine works well with caffeine to aid concentration (it's found in green tea but not coffee). I have no idea about the neurogenesis claims though.
