• Hiccup

  Neuromyelitis Optica (NMO) can have atypical presentations like hiccups, vomiting, etc. which is classically described as the area postrema syndrome. [ncbi.nlm.nih.gov]

• Distractibility

  Thus, CH attacks frequently wake patients out of sleep. 3 Finally, the clinician should not be distracted by migrainous symptoms—photophobia can occur in 91% and phonophobia in 89% of CH attacks, and nausea occurs frequently in cluster as well. 4 All [neurology.org]

HC can also be accompanied by idiopathic stabbing headache, often called “jabs and jolts,” and is frequently associated with an ipsilateral foreign body sensation in the eye, like an eyelash or grit. 13,14 MRIs of the brain are mandatory during the workup [neurology.org]

Despite the existence of clear-cut diagnostic criteria (The International Classification of Headache Disorders, 2 nd edition - ICHD-II) and several therapeutic guidelines, errors in workup and treatment of these conditions are frequent in clinical practice [thejournalofheadacheandpain.springeropen.com]
