Hypoxic-Ischemic Encephalopathy and Other Neonatal Encephalopathies
ABSTRACTPURPOSE OF REVIEWNeonatal encephalopathy is the most common condition in neonates encountered by child neurologists. The etiology is most often global hypoxia-ischemia due to failure of cerebral perfusion to the fetus caused by uterine, placental, or umbilical cord compromise prior to or during delivery. Other etiologies of neonatal encephalopathy include ischemic stroke and intracranial hemorrhage, infection, developmental anomalies, and inborn errors of metabolism.RECENT FINDINGSTherapeutic hypothermia is standard of care for the treatment of neonatal encephalopathy presumed to be caused by hypoxia-ischemia. The ...

Neurologic Complications in the Pediatric Intensive Care Unit
This article discusses an approach to the recognition and management of seizures, stroke, and cardiac arrest as complications of other critical illnesses in the pediatric intensive care unit.RECENT FINDINGSConvulsive and nonconvulsive seizures occur frequently in children after cardiac arrest or traumatic brain injury and during extracorporeal membrane oxygenation. Seizures may add to neurologic morbidity, and continuous EEG monitoring is needed for up to 24 hours for detection. Hypothermia has not been shown to improve outcome after cardiac arrest in children, but targeted temperature management with controlled normotherm...

Apraxia, Neglect, and Agnosia
PURPOSE OF REVIEW In part because of their striking clinical presentations, disorders of higher nervous system function figured prominently in the early history of neurology. These disorders are not merely historical curiosities, however. As apraxia, neglect, and agnosia have important clinical implications, it is important to possess a working knowledge of the conditions and how to identify them. RECENT FINDINGS Apraxia is a disorder of skilled action that is frequently observed in the setting of dominant hemisphere pathology, whether from stroke or neurodegenerative disorders. In contrast to some previous teaching, ...

Subarachnoid Hemorrhage
This article reviews the epidemiology, clinical presentation, diagnosis, and management of patients with aneurysmal subarachnoid hemorrhage (SAH). SAH is a type of hemorrhagic stroke and is a neurologic emergency with substantial morbidity and mortality. This article reviews the most common and potentially life-threatening neurologic and medical complications to promote their early recognition and prevent secondary brain injury. RECENT FINDINGS Over the past 30 years, the incidence of SAH has remained stable; yet, likely because of improved care in specialized neurocritical care units, discharge mortality has considerab...

Cardiac and Pulmonary Disorders and the Nervous System
This article reviews the neurologic complications encountered with cardiac and pulmonary disorders, specifically focusing on endocarditis, cardiac arrest, heart failure, hypercapnia, hypoxia, and cystic fibrosis. As neurologic dysfunction is one of the most frequent complications of these diseases and may even be the presenting symptom, it is important to be familiar with these complications to foster early recognition and intervention. RECENT FINDINGS Advances have been made in the identification of which patients can safely undergo valvular surgery for treatment of infective endocarditis in the setting of stroke, whic...

Retinal and Optic Nerve Ischemia
Purpose of Review:This review focuses on aspects of retinal and optic nerve ischemia that may be encountered by neurologists. Recent Findings:Recent guidelines have emphasized the similarities between cerebral and retinal ischemia in terms of etiologic workup, acute management, and subsequent stroke risk. However, although ischemic optic neuropathies reflect optic nerve ischemia, they result from local small vessel disease and are not associated with a higher risk of cerebral infarction. Their management is therefore very different from acute cerebral ischemia. It is essential to rule out giant cell arteritis in all patien...
