Bipolar I and bipolar <scp>II</scp> subtypes in older age: Results from the Global Aging and Geriatric Experiments in Bipolar Disorder (<scp>GAGE‐BD</scp>) project

BD-I and BD-II patients did not differ in terms of general functioning, cognitive impairment or somatic burden. Some clinical differences were observed between the groups, which could be the consequence of diagnostic definitions. The distinction between BD-I and BD-II is not the best way to subtype OABD patients. Future research should investigate other disease specifiers in this population.
