Patients often ask questions about being stable on Parkinson’s medication for many years and then recently experiencing hallucinations or hyperexcitability, being paranoid, hearing or seeing strangers in the house. In reality, family members report this problem more often because patients usually don’t think they are hallucinating, but to family members it seems like they are talking nonsense, or having nightmares at night, etc. This condition is most likely a side effect of the medication. There are several major medications that can cause such side effects in Parkinson’s patients who are commonly prescribed medications. Antan (benzhexol hydrochloride), as well as Tamsulosin and Senfro. This side effect is also stated in their drug instructions. Of course these are very effective anti-anti-Parkinsonian drugs, and the solution is to reduce the dosage appropriately or switch to other anti-Parkinsonian drugs, provided that this is always done under medical supervision. For some patients, the reduction or replacement of these drugs is going to affect the treatment of Parkinson’s. Then there is another option to consider, which is the installation of a brain pacemaker. This is a surgical procedure that does not sound related to medication side effects. The reasoning behind this is that after the surgery the patient’s Parkinson’s symptoms improve greatly and medications can be tapered as appropriate, especially those with significant side effects. Of course this must also be done under the guidance of a physician, and patients should not stop medications at will or choke on them or be resistant to them. The combination of surgery and medication can avoid many of the side effects of medication.
