Recently, my family has joined the unfortunate ranks of those who have been impacted by Alzheimer’s disease. My mom started showing early signs of the disease a few years ago, and it has slowly and stubbornly progressed ever since. The toll that Alzheimer’s is taking on my mom is obvious and devastating. Less obvious, but just as significant, is the impact it is having on my dad. As my mom’s primary caregiver, it’s been said that my dad must ride the world’s tallest, fastest and scariest emotional roller coaster each and every day. Sadly, in my observation, this is absolutely true.
