1.3 million people in the UK have bipolar. That's 1 in 50 people.  Bipolar is one of the UK’s most common, long-term conditions. There are almost as many people living with bipolar as cancer (2.4%)! It’s also more than twice as common as dementia, epilepsy, autism, arthritis, and learning disabilities.  It takes on average 9 years to get a correct diagnosis of bipolar and there is a misdiagnosis an average of 3.5 times. Shocking, eh?  So, what is bipolar disorder?
