Regarding excessive saliva frequently seen in patients with Parkinson's disease, there is now a simple treatment for this problem. Infiltration using a small needle with botulinum toxin (Botox) into the parotid gland on both sides almost eliminates the excessive drooling. So far I have treated three patients with this problem and two did not have drooling anymore and one had great improvement. It is reversible and injections need to be carried out around three to four times a year. It is not painful and no side effects. It saves a lot of money on the excessive laundry of shirts and ties.
