They did an MRI and determined it was a stroke and the neurologist said there was a three hour window of opportunity for administering a certain medicine. There were risks involved (how can there not be?) and dad agreed to have the drug. They said his speech should improve, but we still haven't seen that. My cousin in CA is a speech therapist for stroke patients, so I called her up and got some great advice and heads-up on things we should be expecting from the SLP. By Tuesday night he was moved to the ICU and removed the oxygen tubes. He seemed very coherent, just unable to speak. He understood when you talked to him (of course, he's lost a lot of hearing from his years in a paper mill) just was unable to answer. We even tried letting him write something, but being without his glasses and his right hand so weak, it was illegible. When I saw him on Wednesday, he was sitting up and eating a bit of dinner.
He'll probably be there one more night and then we're off on another adventure and seeing how his speech comes back and physically what he's able to do. We're so thankful for God's protection that he wasn't driving at the time and that mom caught it so quick.
