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 ...
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.
Symptoms are frequently worsened by a Valsalva maneuver, or by being upright for long periods of time. The reason that being upright is problematic is that gravity allows increased interaction between the brain stem and the top of the spinal column, increasing symptoms. Lying in the supine position can bring short-term relief. Lying supine ...
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 ...
WASHINGTON (Reuters) - Pregnancy triggers vast changes in a woman's body - hormonal, cardiovascular, respiratory, gastrointestinal, urinary and more. And, as a new study reveals, the brain ...
Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia, cerebral infarction ...
Of the twelve viable children known to be delivered from brain dead mothers on prolonged somatic support between 1982 and 2010, the mean gestational age at the time of brain death was 22 weeks and the mean gestational age at delivery was 29.5 weeks, leading to an average length of somatic support for the mothers in the ICU of 7.5 weeks (52.5 days).
15,000 to 20,000. Brain death is the permanent, irreversible, and complete loss of brain function, which may include cessation of involuntary activity necessary to sustain life. [1][2][3][4] It differs from persistent vegetative state, in which the person is alive and some autonomic functions remain. [5] It is also distinct from comas as long ...
