Hi nen83,
Welcome to the forum.
I’m really sorry to hear about what you and your family have been going through. Unfortunately, Impulsive and compulsive behaviour is a possible side effect of some Parkinson’s drugs. You’ll see on the forum that many of other members have experienced the same side effects - Hypersexuality problems - #32 by goldengirl
Only a relatively small number of people experience this, but it can have a big impact on the person affected and those around them. I’m pretty confident that your dad is experiencing this and I would urge you to speak to his GP or Parkinson’s nurse about this asap so that they can review his medication. There is treatment available which involves reducing the daily dose of Parkinson’s medication, or changing a dopamine agonist prescription to levodopa or another type of medication. We have a lot more information on this via our website here - Impulsive and compulsive behaviours in Parkinson's | Parkinson's UK.
We have produced an ‘Impulsive and compulsive behaviour in Parkinson’s checklist’ which can help you talk about this issue with your dad’s specialist or Parkinson’s nurse - you can access this here - https://www.parkinsons.org.uk/sites/default/files/2017-03/Impulsive%20and%20compulsive%20behaviour%20checklist.pdf.
Our confidential helpline and Parkinson’s local advisers are here to answer any questions you have about impulsive and compulsive behaviour. Feel free to give us a call on 0808 800 0303.
I hope you find this information helpful and somewhat reassuring knowing that your dad’s behaviour isn’t uncommon for people with Parkinson’s.
Best wishes,
