Christina Applegate, a 54-year-old actress, has learned that she does not have multiple sclerosis. She had lived with that diagnosis for five years, despite the movement-related symptoms that led to the earlier conclusion. The actress remains off screen because another health problem still affects her ability to move. Her situation has therefore not returned to normal, even though the multiple-sclerosis diagnosis has been overturned. Applegate described the change as being "back to square one," reflecting the need to reassess her condition and treatment. The episode has prolonged her absence from acting while she continues to seek answers.
