Not terrible but not great news

My neurologist called and said that I have enlarged ventricles in the brain. (No joke there) She said that it could have been caused by head trauma or some serious infection. She said that there is no telling when it may have happened. It could have happened decades ago. She also said  that it could have taken many  years before it caused  any symptoms.  Now I have to wait until she schedules another test where the lunbar is punctured to draw some fluid. The sort of good news is that if I respond well to the test then surgery and the implantation of a shunt in my brain may make my symptoms disaappear and delay/prevent further symptoms. The shunt will prevent excessive fluid build up and the resultant pressure on areas of the brain. I am not jumpng for joy (I'd fall on my butt if I tried) but I'm not depressed either. I think I knew for awhile that something was wrong. I'm just grateful that it wasn't anything worse. I'm also grateful that my symptoms are really pretty mild.  Oh well, it's better to know than not to know. And it's good that there is strong chance for improvement.  Sorry if this is a downer,Tom
