Since the designation by President Ronald Reagan in 1983, November has been a time to promote awareness of Alzheimer’s disease. At the time, less than 2 million people were known to be afflicted. Today that number has more than doubled, to over 5 million. To show your support, you can wear a purple ribbon… but understand Alzheimer’s disease is also important. Roughly 500,000 people are diagnosed with Alzheimer’s every year, and the symptoms can begin as early as middle age.
