Headache is relatively common in patients with cerebrovascular disorders. The reported frequency of stroke-related headache ranges from 7% to 65% and different types of headache, such as onset headache, sentinel headache, or delayed headache, may be observed in association with stroke. Headache can be attributed to ischemic stroke, transient ischemic attack, or non-traumatic intracranial hemorrhage, including intracerebral and subarachnoid hemorrhage. ⋯ The suddenness of onset and not its severity is the characteristic feature of the headache in subarachnoid hemorrhage. Referring to unruptured vascular malformations, the headache can be attributed to saccular aneurysm, arteriovenous malformation, dural arteriovenous fistula, dural cavernous angioma, and encephalotrigeminal or leptomeningeal angiomatosis (Sturge-Weber syndrome). It is very important to recognize that in the latter forms the onset of headache may indicate an upcoming bleeding complication.

Vestibular migraine is a chameleon among the episodic vertigo syndromes because considerable variation characterizes its clinical manifestation. The attacks may last from seconds to days. About one-third of patients presents with monosymptomatic attacks of vertigo or dizziness without headache or other migrainous symptoms. ⋯ We prefer the term "vestibular migraine" to "migrainous vertigo," because the latter may also refer to various vestibular and non-vestibular symptoms. Antimigrainous medication to treat the single attack and to prevent recurring attacks appears to be effective, but the published evidence is weak. A randomized, double-blind, placebo-controlled study is required to evaluate medical treatment of this condition.

Historical Article
Chapter 12: the anatomical foundations of clinical neurology.
The chapter provides an itinerary of knowledge on nervous system anatomy as one of the pillars of clinical neurology. The journey starts from the Renaissance explosion on the approach to the human body, its functions and its diseases, dealing with the seminal contributions of Leonardo da Vinci and Vesalius. ⋯ The chapter also includes sections on the contributions of developmental neuroanatomy to neurology, on the history of tract tracing, and on the cytoarchitecture of the cerebral cortex. The never-ending story of the anatomical foundations of clinical neurology continues to evolve at the dawn of the 21st century, including knowledge that guides deep brain stimulation, and novel approaches to the anatomy of the living brain based on rapidly developing neuroimaging technology.
