This is a sad, uncertain story about a beloved singer's health, with her own family split over what's really going on.

• Gladys Knight's son and sister say the 82-year-old singer may have dementia, after a summer performance went viral showing her confused and turned away from the audience.
• Her sister claims to have found dementia medication among her belongings, raising fears she's being pushed to keep touring against her own interest.
• People close to Knight push back, saying no one is forcing her on stage and that performing is therapeutic for her, not harmful.
• Knight herself has announced she'll cut back and perform less often going forward.

Outlook: Expect fewer tour dates from Knight going forward, with her family's disagreement over her health likely to continue playing out publicly.
