My husband 63 yo diagnosed almost 2 years ago from agent Orange. Within this time he meds (levadopa) have been increased to 4x a day plus extended at night. The VA has him seeing a speech pathologist due to difficulty in swallowing. He is involved with tai chi self employed a general contractor but his daily activities have declined and will fall asleep thinking he has not slept at all. They now want to test him for sleep apnea. He is a strong will proud minded man and I am concern these qualities might cause denial and business errors. I need to know if his conditions are normal decline or more rapid? Also I need to know If I should start making provisions of finding a means to supporting us. Without him or license our present construction business will no longer be.
