I Am A Male Age 64. My Speech Is Slurred,

I am a male age 64. My speech is slurred, I'm emotional, off balanced, not focused and have just recently started to drag my one foot. I have been tested by a Specialist to confirm that I did not have a stroke. I did have bellspalsay last year and was thinking that was the cause for my slurred speech. Do you have any suggestions as to what this could be?
