Like many mental health conditions, bipolar disorder often begins in the teenage years, but goes undiagnosed until young adulthood. This may mean that teens may suffer with symptoms for years. It can sometimes be harder to treat mental illness if many years have passed with the symptoms.

To make it worse, untreated bipolar disorder can often result in risky behaviors that have serious consequences. For this reason, it's important to identify the symptoms of bipolar disorder in teens.
