Hello, my Dad finished radiation about 8 weeks ago for a couple of brain tumors in the back and side of his brain. He did great with the radiation, had some swelling and the extreme fatigue. He is still very fatigued but is now starting to have a lot of trouble expressing his thoughts. He said he knows what he wants to say but has trouble getting the right words to come out. He also has had a couple of wrecks in the past couple of weeks and has stopped driving again. I am afraid he is regressing instead of progressing. He had a good check up about 4 weeks ago. Thanks for any info or guidance you might share.
