Hello, my Internet Friends,

I am posting this as an update to my previous post. In April of 2012, I had my 6th surgery (performed by Dr. Daniele Rigamonti at Johns Hopkins) related to my hydrocephalus. The purpose of the surgery was to fenestrate (create openings) in the interpeduncular cyst which was causing the blockage of the flow of my cerebrospinal fluid. Since that operation, I have experienced absolutely no problems with changes in barometric pressure. I can no longer tell you if the pressure has risen or fallen, and neither I nor my wife (who has always been able to judge my pain by my mood) can tell when the barometric pressure has shifted. I have no doubt that for me, my bouts of depression were directly related to the shifts in barometric pressure. My wish for all of you is that research provides the same relief for you that it has for me.

Kindest Regards,
Lon
