According to the search results, Eric on The Bold and the Beautiful has been suffering from tremors, where his hands shake, and he is unable to draw his sketches completely for his upcoming “Battle of the Bands” fashion show. Eric has been keeping his condition a secret from his loved ones, but it has been revealed that he has cerebral vascular disease and TIAs. In a recent episode, Eric and Donna met with Dr. Colby at the Forrester mansion, and it was suggested that Eric may have Parkinsons disease. However, it is important to note that this is a fictional plot line created for dramatic effect, and the actor John McCook, who plays Eric Forrester, is not facing any health issues in real life.
