Hi, Library Lady:
I haven't had your husband's experience regarding speech and shaking hands but my neurosurgeon did countless, basic neurological tests on me in the days, weeks and months following my surgery. Despite a rapid and seemingly complete recovery, I always had a slight neurological deficit but by my last test (June) I was back to normal. These things do take time.
I would expect that your doctor would perform the same kinds of tests on your husband. I don't believe a post-op patient should have these issues at 6 months but it does occur, as you can see. More information on his pre-op condition, size of the tumor and type of surgery would be of some help.
I hope your husbands neurological problems can be resolved in time. I'll certainly pray for him and you, as his advocate and main support. Please stay connected to this forum and let us know how things are going, especially following your doctor visit next month.
Thanks.
Jim
