Even with proper treatment, mood changes can occur. Treatment is more effective when a patient and health care provider work together and talk openly about concerns and choices. Keeping a life chart that records daily mood symptoms, treatments, sleep patterns, and life events can help patients and health care providers track and treat bipolar disorder over time. Patients can easily share data collected via smartphone apps – including self-reports, self- ratings, and activity data – with their health care providers and therapists.
