Sleep terrors are sudden, partial awakenings from deep non-REM sleep, associated with intense motor behavior and strong autonomic responses. Sleep terrors are mainly a childhood phenomenon, with peak prevalence at 5 to 7 years of age. They are usually benign with a tendency for spontaneous resolution. Safety measures are of primary importance to protect the patient from injury, but treatment with medications is not usually necessary.

Reversible cerebral vasoconstriction syndromes (RCVS) are characterized by recurrent, severe “thunderclap” headaches and multifocal cerebral arterial narrowing and dilatation, often complicated by ischemic or hemorrhagic strokes or reversible brain edema. RCVS affects young individuals, mostly women, and have been associated with diverse conditions such as pregnancy, migraine, vasoconstrictive drug use, pheochromocytoma, and neurosurgical procedures. The prognosis is usually excellent, with most patients recovering completely or near-completely within days to weeks.

Takayasu arteritis is a rare form of vasculitis affecting the aorta and its major branches, resulting in large-vessel occlusions. Neurologic complications include cerebral and spinal ischemia, typically secondary to hypoperfusion rather than embolic phenomena. Most commonly, patients report symptoms of presyncope/syncope, lightheadedness, dizziness, and headache during the course of the disease.

Viral myositis manifests with myalgia, weakness, and, rarely, rhabdomyolysis. Although virtually any virus can cause an acute myositis, influenza virus and enterovirus are the most common in North America and Northern Europe. Acute and subacute viral myositis is mostly benign and self-limited. Chronic viral myositis is associated with retroviruses and hepatitis viruses.
