In children, it can be difficult to differentiate between pediatric bipolar disorder (PBD) and attention deficit hyperactivity disorder (ADHD). They are genetically linked, have multiple overlapping symptoms and co-occur at a rate of 60-80%. However, both disorders have distinct characteristics that are important to note. A new study looks at differences found between those with pediatric bipolar disorder and ADHD, focusing on emotional control, memory and inhibition.
