Question

When are imaging studies considered for rapid eye movement (REM) sleep behavior disorder?

Answer 1

Doctors often don't do imaging studies (for example, a CT scan and MRI of the brain) if you have RBD and have no neurologic cause of RBD. But you may get these tests if the neurologic exam points to a possible problem. Doctors should also consider doing imaging studies in people younger than age 40 where there is no known cause of RBD, such as alcohol or medication use.
