Cardiac arrest has a high mortality rate. Postresuscitation encephalopathy is commonly associated with significant morbidity. ⋯ The authors discuss the physiology, pathology, and consequences of cardiac arrest to the central nervous system, and the use of various parameters in prognostication. Induced hypothermia is a new therapeutic development.

Massive cerebral infarcts cause brain edema with midline shifts and impingement on vital structures producing coma and death. The mortality rate is estimated at 80% with standard medical treatment. Surgical decompression with hemicraniectomy has proved to be life saving, but the impact on functional outcomes is largely unknown. The focus of this review is to discuss the treatment options for massive cerebral infarcts. ⋯ Hemicraniectomy is emerging as a promising treatment of patients with massive cerebral infarcts, but only select patients benefit from this procedure. Further information from randomized controlled trials is required to elucidate the best treatment options for this kind of stroke.

The management of chronic pain represents a significant public health issue in the United States. It is both costly to our health care system and devastating to the patient's quality of life. The need to improve pain outcomes is reflected by the congressional declaration of the present decade as the "Decade of Pain Control and Research," and the acknowledgment in January 2001 of pain as the "fifth vital sign" by the Joint Commission of Healthcare Organizations. ⋯ The rapidly evolving symptom- and mechanism-based approach to the treatment of neuropathic pain holds promise for improving the quality of life of our patients with neuropathic pain.

Neurocritical care is a specialty that focuses on the critical care management of patients with catastrophic neurologic diseases. Brain ischemia and hypoxia are often central causes of brain damage in these patients. Until recently, the only methods widely accepted for monitoring in the neurological intensive care unit have been intracranial pressure and cerebral perfusion pressure monitoring. Recent developments in technology have resulted in several new monitoring techniques that can provide the neurointensivist with information, at the cellular level, that can help guide management. ⋯ New monitoring techniques can provide the neurointensivist with crucial information about brain physiology and metabolism. Combining these techniques ("multimodal monitoring") can produce a more accurate overall picture. This approach, along with new computer systems for integrating data at the bedside, may change the way patients with brain injury are monitored and treated in the future.

Patients with migraine are at an increased risk for white matter lesions, typically multiple, small, punctate hyperintensities in the deep or periventricular white matter, best observed on magnetic resonance imaging utilizing T2-weighted or FLAIR sequences. The underlying pathogenesis of white matter lesions in migraineurs is unknown, and the lesions are usually nonspecific and of unclear clinical significance. ⋯ While the prevalence of nonspecific white matter lesions in migraineurs is increased, the white matter lesions may occasionally represent a secondary cause for headache such as CADASIL. Greater awareness of the unique clinical, neuroimaging, and pathologic features, as well as the availability of diagnostic genetic testing, should enhance the recognition and diagnosis of this fascinating condition.
