Hello. I am glad you are here! I have suffered from OSA for six years although it was only medically diagnosed after four years. In 2003, I had a non-malignant brain tumor removed from my frontal lobe (meningioma) and everything went well although I do still suffer from seizure disorder which is well control. I have had, over the past 8 years I have had some bouts of depression that were so painful that once, I actually walked into a hospital ER to ask for help. I also have problems concentrating. I am frustrated with my sleep doctor because he only treats the 'breathing' problem (which is still not properly sorted out) and is not interested in the other symptoms like depression and ADHD. Firstly, can a non-malignant brain tumor have any link with OSA? Secondly, it is typical that sleep doctors only treat the SA and not the other symptoms suffered as a result. I don't want to have to go to numerous doctors when there is a clear link to these disorders. Thank you so very much Claire, Raleigh, North Carolina
