WESTPORT — A community service for people and their families affected by memory loss will take place Sunday at Saugatuck Congregational Church.

The ecumenical service, co-sponsored by the church and Alzheimer’s Association, will take place at 3 p.m. in the church, 245 Post Road East. A reception will follow the service.

The hour-long worship service will include readings and hymns, “along with reflections on the challenges of living with Alzheimer’s and related conditions,” organizers said. The sanctuary is accessible to people with disabilities.

“Losing one’s memory can feel like losing one’s sense of self. It’s frightening,” the Rev. Allison Patton, the pastor of Saugatuck Congregational Church, said in a release publicizing the event. “How can we stay connected to each other and trust God’s continued presence even in times of distress? We hope this worship will offer comfort and convey that no one is alone on this journey.”

In a related program, the movie, “Still Alice,” about a woman with early onset Alzheimer’s, will be screened at 4:30 p.m. Thursday at the Westport Center for Senior Activities, 21 Imperial Ave. There is no admission fee.

Purple, the Alzheimer’s Association signature color, will be displayed for two weeks around town to raise awareness, with purple ribbon bows wrapped around trees lining Main Street. Task Home Care Services, located above the Starbucks downtown, will illumine its building with purple lighting.
