Robin McIntyre, who's 39, lives every day with the knowledge that she's almost certain to get Alzheimer's. Her family carries a genetic mutation that leads to early onset of the disease. Ten years ago, McIntyre, who lives in Laramie, Wyoming, tested positive for the mutation. Her sister Jessica McIntyre, of Lakewood, didn't. Nor did their other sister. We get an update from the pair, who we first spoke to in 2016, about how they're planning for their futures and about some of the research their family has been involved in.
