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 ]
If the person has frequent seizures, any improvement will be obvious after a short time. However, if the seizures generally occur far apart it may take months to determine whether the time between seizures is increasing. At some epilepsy centers, patients are offered additional conventional or experimental medications before surgery is considered.
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 ...
At the time this article was written, only ten patients had undergone the surgery to sever their corpus callosum (corpus callosotomy). Four of these patients had consented to participate in Sperry and Gazzaniga's research. After the corpus callosum severing, all four participants' personality, intelligence, and emotions appeared to be unaffected.
Cordotomy is performed as for patients with severe intractable pain, usually but not always due to cancer.Being irreversible and relatively invasive, cordotomy is used exclusively for pain where treatment to level 3 of the World Health Organization pain ladder (i.e., use of major opiates such as morphine) has proved inadequate.
In neurosurgery, as a treatment for severe epilepsy, the corpus callosum, or the area of the brain that connects the two hemispheres, would be completely bisected.By eliminating the connection between the two hemispheres of a patient's brain, electrical communication would be cut off greatly diminishing the amount and severity of the epileptic seizures.
Recovery after ATL can take several weeks to months. Anti-seizure medications will be continued for several months after ATL. As it is an open surgery it takes time for the brain to heal. [10] Speech therapy, occupational therapy, etc. can help recovery. About 90% of people experience an improvement in seizures after temporal lobectomy.
The procedure of surgically removing the corpus callosum is called a corpus callosotomy. Patients who have undergone a corpus callosotomy are colloquially referred to as "split-brain patients". This is because their brain's left and right hemispheres are no longer connected by the corpus callosum. [citation needed]
