Alzheimer's is a cruel disease that has impacted the lives of thousands of people in Colorado - most recently Annabel Bowlen, the wife of Denver Broncos Owner Pat Bowlen.

Annabel Bowlen announced Thursday her diagnosis, nearly four years after Pat Bowlen was also diagnosed with the disease.

Alzheimer's disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks, according to the U.S. Department of Health & Human Services. In Colorado, about 69,000 people were diagnosed with the disease in 2017, according to the Alzheimer's Association.
