Brainstem death is a clinical syndrome defined by the absence of reflexes with pathways through the brainstem – the "stalk" of the brain, which connects the spinal cord to the mid-brain, cerebellum and cerebral hemispheres – in a deeply comatose, ventilator -dependent patient. Identification of this state carries a very grave prognosis for ...
Researchers said on Monday they have for the first time mapped the changes that unfold as a woman's brain reorganizes in response to pregnancy, based on scans carried out 26 times starting three ...
Treatment. Immunotherapy. [2] Bickerstaff brainstem encephalitis is a rare inflammatory disorder of the central nervous system, [3] first described by Edwin Bickerstaff in 1951. [4][5] It may also affect the peripheral nervous system, and has features in common with both Miller Fisher syndrome and Guillain–Barré syndrome.
An elevated MSAFP measured at 16–18 weeks gestation is a good predictor of open neural tube defects, however the test has a very high false positive rate, (2% of all women tested in Ontario, Canada between 1993 and 2000 tested positive without having an open neural tube defect, although 5% is the commonly quoted result worldwide) and only a ...
Anencephaly. Death typically occurs within hours to days after birth. Anencephaly is the absence of a major portion of the brain, skull, and scalp that occurs during embryonic development. [1] It is a cephalic disorder that results from a neural tube defect that occurs when the rostral (head) end of the neural tube fails to close, usually ...
Second-impact syndrome. Second-impact syndrome (SIS) occurs when the brain swells rapidly, and catastrophically, after a person has a second concussion before symptoms from an earlier one have subsided. This second blow may occur minutes, days, or weeks after an initial concussion, [1] and even the mildest grade of concussion can lead to second ...
Maternal somatic support after brain death occurs when a brain dead patient is pregnant and their body is kept alive to deliver a fetus. It occurs very rarely internationally. Even among brain dead patients, in a U.S. study of 252 brain dead patients from 1990–96, only 5 (2.8%) cases involved pregnant women between 15 and 45 years of age.
Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is a rare condition in which parts of the brain are affected by swelling, usually as a result of an underlying cause. Someone with PRES may experience headaches, changes in vision, and seizures, with some developing other ...
