Talk:Hemispherectomy

message: "Hemispherectomy is considered the most invasive surgical operation in use today, although not the most dangerous."  In addition to lacking a citation, this statement seems rather dubious, in that it doesn't specify what the more dangerous diseases are.  I would expect to see something like, "although it isn't as dangerous as <some set of operations> like operations x, y, and z."  I'll tag it with a . Randomizer3 (talk) 23:13, 22 February 2015 (UTC)
thread_title:  Not the most dangerous surgical procedure? 

message: This statement is sourced to the following:
http://onlinelibrary.wiley.com/doi/10.1111/j.0013-9580.2004.15303.x/abstract
Yet the concluding sentence of that abstract is "Regardless of etiology, most patients showed only moderate change in cognitive performance at follow-up."
"Moderate" is hardly equivalent to "minimal". I recommend the text in the current article be altered to the following: "Studies have found...only moderate changes in cognitive function overall."

message: I once read a science fiction book long ago in middle school which involved the main character landing alone on the moon to scout it out and receiving a hemispherectomy.  The moon was divided up into caches of war computers and robots belonging to different countries there to fight out proxy, if unwitnessed, wars.  Yes, quite the story :) it made an impression on my adolescent mind.  I'd really like to find out the title or author again; I'm curious if anyone who happens on this page knows.  Thanks

message: One major flaw that I'm unhappy with is the "is used to treat" part of the initial description. I know that I'm not being complete there, and there's some overlap, but I don't know enough about the field to be exact. If someone who does know something about neurosurgery can edit that, I'd be thrilled.
Beyond that, I think the only major flaw is the rather roughly handled references in the last paragraph. -Harmil 28 June 2005 13:27 (UTC)
=== Age and indications and neuroplasticity ===
Someone had listed the maximum age of surgery to be 5 years old.  However, the article referenced laterVining EP, Freeman JM, Pillas DJ, Uematsu S, Carson BS, Brandt J, Boatman D, Pulsifer MB, Zuckerberg A. Why would you remove half a brain? The outcome of 58 children after hemispherectomy-the Johns Hopkins experience: 1968 to 1996. Pediatrics. 1997 Aug;100(2 Pt 1):163-71.   clearly states, "Mean age at surgery was 7.2 years."  I am changing this to reflect that a hemispherectomy is almost always performed in children due to the concept of neuroplasticity.
In reference to neuroplasticity, a 2002 articleR. Chen, L. G. Cohen and M. Hallett, Nervous system reorganization following injury. Neuroscience. 2002;111(4):761-73.  seems to support the concept of reinforcement of already existing ipsilateral pathways as opposed to development of new pathways. --Kevin Dufendach 15:20, 13 October 2007 (UTC)

message: "It is reserved for cases which can't be managed with medication alone." Wow...that make it sound like hemispherectomies is performed whenever medications have a less than desirable effect. Hemispherectomy is a last ditch solution (and not a very good one) to treating extreme epilepsy. Fixed. Jumping  cheese 04:38, 3 October 2007 (UTC)

message: "Most patients end up with mild to severe mental retardation, which is usually already present before surgery." is functionally equivalent to "Some normally functioning patients end up with mild to severe mental retardation.", but without the obvious "Patients who are mentally retarded before are still mentally retarded after.".
