Stroke & Vascular Disorders
Subarachnoid hemorrhage (SAH), often occurring from rupture of an intracranial aneurysm, typically presents with a sudden severe headache and neck stiffness, and can be complicated by fatal rebleeding, arterial vasospasm producing ischemia, seizures, metabolic derangements, and venous thrombosis. The most common presenting complaint in SAH is the sudden onset of a painful headache followed by pain radiating into the occipital or cervical region. Meningismus develops as blood flows into the spinal subarachnoid space.

Neuro-Ophthalmology & Neuro-Otology
Ophthalmologic symptoms are common in patients with movement disorders and adversely impact their quality of life. They may arise from problems with visual processing, impaired subcortical and cortical control of eye motility, and other still poorly understood mechanisms. Some ophthalmologic findings in Parkinson disease correlate with disease progression and might potentially serve as disease biomarkers.

General Child Neurology
Manifestations of hydrocephalus can present in an acute (often life-threatening), subacute, or chronic manner, with acute manifestations including vomiting, lethargy, irritability, and seizures. In newborns, this is usually accompanied by a bulging fontanelle, a large or enlarging head, splaying of the sutures, and sometimes forced downward deviation of the eyes. This is due to alterations in the normal cerebrospinal fluid dynamics, which result in elevated intracranial pressure.

Neuropharmacology & Neurotherapeutics
Oxcarbazepine is a homologue of the well-known antiepileptic drug carbamazepine. It was developed as an alternative to carbamazepine for patients who had adverse reactions to carbamazepine or diphenylhydantoin. Oxcarbazepine is indicated as a monotherapy for the treatment of partial epilepsy with or without secondary generalization.

Swallow syncope is caused by stimulation, irritation, or dysfunction of the afferent origin of a vagovagal reflex (eg, the distal esophagus), the vagus nerve itself, or the efferent target of the vagovagal reflex (ie, the heart). It is frequently triggered by liquids, particularly cold, carbonated beverages, and may occur within 3 to 5 seconds of swallowing. Many bouts result only in presyncope, with associated visual greyout or tunnel vision.

Episodes of periodic paralysis typically involve generalized muscle weakness with hypotonia and areflexia but spare bulbar and respiratory muscles and cognition. During attacks, affected muscles are in a state of sustained depolarization and are electrically inexcitable. Attacks may last minutes, hours, or even days. Episodes are often precipitated by specific triggers (behavior/diet) or are associated with abnormal serum potassium levels.
