Cerebral capillaries lack fenestrations and have tight junctions. They are active in the process of pinocytosis. All these features regulate the passage of highly polar hydrophilic molecules allowing virtually unrestricted passage of lipid-soluble substances. Cerebral capillaries have 2-4X the number of mitochondria as other capillaries. Cerebral capillaries have an array of important enzymes: ATPase, dehydrogenase, monamine oxidase, DOPA decarboxylase, acid and alkaline phosphatase, NAD and others. BBB has both central (cholinergic and aminergic) and peripheral (sympathetic and parasympathetic) innervation. Areas without a BBB include: choroid plexus area postrema median eminence neurohypophysis pineal body subforniceal organ commissural organ supra-optic crest.

Cerebral Edema Cerebral Edema Intracellular (Cytotoxic) edema Cellular swelling, usually of astrocytes in the grey matter, and classically is seen following cerebral ischema caused by cardiac arrest or minor head injury. The blood brian barrier(BBB) is intact. Intracellular edema is usually not clinically significant, and is reversible in its early phases. Extracellular (vasogenic) edema A consequence of vascular injury with disruption of the BBB. Grossly , the gyri are flattened and the sulci narrowed; the white matter is moist and swollen. Microscopically, there is micro-vacuolization of the white matter, poor staining, and "halo's" around nuclei. Causes include trauma, tumor, and abscess. Ultimately, these changes can lead to herniation. BRAIN HERNIATION Is a major consequence of cerebral edema. Because of the rigid skull and partitioning of the cranial vault by the falx cerebri and tentorium cerebelli, when the brain swells it is displaced relative to these partitions or is pushed toward the foramen magnum. There are several types of brain herniations - classified by the part that is herniated or the structure under which it has been pushed. Transtentorial herniations are of two main types: Uncal herniation The medial temporal lobe (uncus) herniates through the gap between the cerebral peduncles and the tentorium.

Suggested Readings Introduction In 1922 Banting and Best introduced insulin into clinical practice. A decade later the first reported case of cerebral edema complicating diabetic ketoacidosis (DKA) was reported by Dillon, Riggs and Dyer writing in the pathology literature. While the syndrome of cerebral edema complicating DKA was either not seen, ignored, or was unrecognized by the medical community until 3 decades later when the complication was again reported by Young and Bradley at the Joslin Clinic, there has since been a flurry of case reports in the 1960's and 1970's and basic and clinical research from the 1970's to the 1990's leading to our present day acceptance of this as a known complication of DKA, or of the management of DKA. In fact, we now recognize that the cerebral complications of DKA (including much less frequent cerebral arterial infarctions, venous sinus thrombosis, and central nervous system infections) are the most common cause of diabetic-related death of young diabetic patients (

var MenuLinkedBy='AllWebMenus [2]', awmBN='530'; awmAltUrl=''; Home Medical Reference Outdoor Health / Safety High-Altitude Cerebral Edema High-altitude cerebral edema (HACE) is the medical term for a disorder (theoretically linked to brain swelling) that involves an alteration of mental status seen at high altitude, related to diminished atmospheric oxygen. Symptoms include difficulty walking (inability to walk a straight line, staggering, or frank inability to walk), headache (often throbbing), confusion, difficulty in speaking, drowsiness, vomiting, and, in severe cases, blindness, unconsciousness, paralysis, and/or coma. A victim may suffer from HACE and high-altitude pulmonary edema (HAPE) at the same time. Other symptoms may include hallucinations, paralysis of an arm and/or leg, and seizures. Victims are often gray or pale in appearance. Imbalance or the inability to walk heel to toe in a straight line is a very worrisome sign and should prompt immediate action to treat the victim. The treatment for HACE is immediate descent to an altitude below one at which the victim previously had no symptoms, and the

Cerebral edema From Wikipedia, the free encyclopedia. Cerebral edema is swelling of the brain which can occur as the result of a head injury, cardiac arrest or from the lack of proper altitude acclimatization Symptoms of cerebral edema include headaches , decreased level of consciousness, hallucinations , psychotic behavior, memory loss and coma . If left untreated, it can lead to death (r. Bruce Lee High Altitude Cerebral Edema (or HACE ) is a severe (frequently fatal) form of altitude sickness . HACE is the result of swelling of brain tissue from fluid leakage. Symptoms can include headache, loss of coordination (ataxia), weakness, and decreasing levels of consciousness including disorientation, loss of memory, hallucinations, psychotic behavior, and coma. It generally occurs after a week or more at high altitude . Severe instances can lead to death if not treated quickly. Immediate descent is a necessary life-saving measure (2,000 - 4,000 feet). There are some medications (e.g. dexamethasone ) that may be prescribed for treatment in the field, but these require proper medical training in their use. Anyone suffering from HACE must be evacuated to a medical facility for proper follow-up treatment. A

This is especially for persons who normally reside at or near sea level. Causes, incidence, and risk factors Return to top Reduced atmospheric pressure and a lower concentration of oxygen at high altitude are the causes of this illness. It affects the nervous system, lungs, muscles, and heart. Symptoms can range from mild to life-threatening. In most cases the symptoms are mild, but in severe cases fluid collects in the lungs ( pulmonary edema ) causing extreme shortness of breath and further decreasing oxygenation.
