When I was in the psych hospital several years ago(not this last time) me pdoc wanted to give me shock treatments b/c I couldn't get well but my heart couldn't take it. So he did a spinal tap on me and found out I had seizures(i don't remember what kind but nothing like Jewell's) Everytime i would get really depressed I was having seizures. So physical problems can cause mental problems. He was the first pdoc who ever checked me for a physical problem causing my severe depression.
