> The mice had previously shown signs of cognitive decline, but after all three doses, the animals performed on par with their healthy peers in spatial learning and memory tasks. The benefits lasted at least six months.

1. This is great news… for mice with Alzheimer’s that don’t mind treatments every 6 months.

2. It’s crazy to think about something like this actually curing Alzheimer’s in humans, even if for just 6 months. Even more so if repeated doses have the same effects.

3. As with all of these studies, mice != humans, but it’s nice to have hope.

Side note: the temporary part of #2 makes me think about The Last Days of Ptolemy Grey [1]. It’s hard to fathom having a relative “come back” like that for a short time. Or even permanently.
