PURPOSE OF REVIEW: The medical aphorism that common things happen commonly makes 
unique (and less common) migraine subtypes especially appropriate to review for 
the general neurologist. This article also identifies some rare headache 
disorders and other disturbances, and offers strategies to manage them.
RECENT FINDINGS: This article discusses migraine with brainstem aura, which is 
troublesome clinically and has had a change in terminology in the International 
Classification of Headache Disorders, Third Edition, beta version (ICHD-3 beta), 
and hemiplegic migraine, which is also troublesome in practice. The rare 
headache disorder hypnic headache and the exploding head syndrome are also 
discussed. When hypnic headache is recognized, it is eminently treatable, while 
exploding head syndrome is a benign condition with no reported consequences.
SUMMARY: Unique migraine subtypes, rare headache disorders, and other 
disturbances present to neurologists. When recognized, they can often be managed 
very well, which offers significant benefits to patients and practice 
satisfaction to neurologists.
