Obsessive Compulsive Disorder (OCD). Not just a disorder for overactive cleaners, but more serious cases include Sophie who has to constantly check she hasn’t killed anybody in the last 5 minutes. Richard is terrified of touching the bin, and Nanda is about to have pioneering brain surgery to stop her worrying about components on her body – that her eyebrow might not be aligned or that she has bad breath.
