A corpus callosotomy (/ k ə ˈ l ɔː s (ə) t ə m iː /) is a palliative surgical procedure for the treatment of medically refractory epilepsy. [1] The procedure was first performed in 1940 by William P. van Wagenen. [ 2 ]
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.
Corpus callosotomy is a palliative procedure for specially severe cases of epilepsy. This corpus callosum is a large bundle of nerve fibers that connects both brain halves with each other. To prevent the spreading of seizures from one brain hemisphere (brain half) to the other the corpus callosum can be split.
The symptoms of refractory (difficult to treat) epilepsy can be reduced by cutting through the corpus callosum in an operation known as a corpus callosotomy lobotomy paralysis. [28] This is usually reserved for cases in which complex or grand mal seizures are produced by an epileptogenic focus on one side of the brain, causing an ...
The longitudinal fissure plays a key role in corpus callosotomy, neurosurgery resulting in split brain, as it provides unobstructed access to the corpus callosum. Corpus callosotomy is one of the procedures used for pharmacologically treating intractable epilepsy cases, and it consists of the division of the nerve fibers running between the two ...
These cuts are thought to interrupt some fibers that connect neighboring parts of the brain, but they do not appear to cause long-lasting impairment in the critical functions that these areas perform. Multiple subpial transections can help to reduce or eliminate seizures arising from vital functional areas of the cerebral cortex.
6 Potential Long-Term Effects of Ozempic. You may have heard about — or maybe even experienced — the short-term side effects of Ozempic® — such as nausea, vomiting, constipation, and diarrhea.
Another term that falls under the hemispherectomy umbrella includes hemidecortication, which is the removal of the cortex from one half of the cerebrum, while attempting to preserve the ventricular system by maintaining the surrounding white matter. Hemidecortication was originally developed as a possible strategy to mitigate some of the ...
