I have spent significant time at altitude (walk up Mt.Whitney twice), trips to Nepal and Tibet, multiple US mountain resorts etc. and actually acclimitized better than some who did not later develop diagnosis of PD. I have also been through the atititude literature and d not recall any comments about Damox and PD. Any references to this subject would be appreciated. Except for cross sensitivity to sulf drugs there are few dangers from diamox in the doses recommended for use in altitude problems. I would love to hear about other information on this subject. Susceptibility to altitude illness is most likely related to central brain modulation of response to reduced barometric pressure and/or oxygen availibility in the inspired air mixture. Is there some relationship between the central neural sites controlling response to altitude and those reated to developent of PD ??
