Things that get screwy after a stroke can get better. I had a stroke back in July 2014. Had trouble waking but walking just one house further from home each time it was nice from March to July 2015 got me up to 1.25 miles before I had to take a rest. Was watching a baseball game and the Word Cup while in rehab and they a looked like they were standing in a line, although I knew they were baseball and soccer games. The things in the room looked normal. That lasted only a few days. Only residual effects are a very, very slight weakness on my left side when lifting heavy stuff, needing to make a list while shopping for >3 items and geting dizzy after looking up for a while which goes away immediately after looking forward and closing my eyes for a few seconds. I am very glad he recovered and the stroke has brought back his common sense.
