I am 64, back in Dec. I had flu like symptoms with hacking cough that lasted for 3-4 months. I now have slurred speech that is getting worse, uncontrollable laughter and crying, but otherwise feel great am eating normal with plenty of exercise. I have had a chest ex ray , CT scan with dye, nose scope down throat, and endoscopy that showed nothing but normal on all tests. I m waiting for appt. with neurologist hopefully in Nov. but worried that is a long time to wait with speech becoming more difficult. Please help.
