Repetitive breath-hold diving causes serious brain injury. Undersea Hyperb Med.
2010 Jan-Feb;37(1):7-11. PubMed PMID: 20369648.
 
nitrogen induced in Amas. Title is misleading as it doesn't say deep breath-hold diving.
 
Ah...very well then.

I'll switch the lights off when everyone has left the building.
 
I copied the "misleading" title to turn somekind of attention. I read the full article, and it's a case report about DCS involving the brain.
The diver was a male japanese freediver (AMA) who perform partially assisted dives to 22 meters, dive duration was 40-80 seconds, and surface interval 20-30 seconds. He usually do this profile for 5 - 6 hours.
Of course this is not the case of competitive freediving, but anyway it deserves our attention. As far as I remember Davide Carrera also have a very intense freediving work as spearo.
In my opinion DCS and Lung squeeze are the dark side of freediving
 
Thanks for the good housekeeping Trux.

Just to be crystal clear for anyone coming along later:

The term "brain injury" in the title of this article is likely referring to the injuries sustained as a result of decompression illness brought on by freediving. The injuries don’t appear to have been caused simply by breath holding, nor simply by freediving, but by repeated freedives without adequate surface interval breathing.

In short: it’s very possible to get bent freediving, especially if you do repeated, deep freedives and don’t take adequate surface intervals between freedives.
