Impulsive: 9. Blame Game

Respected local solicitor Andrew is sent to prison - but the devastating impact of the side effects of his Parkinson’s medication continues.

BBC Investigations Correspondent Noel Titheradge has been contacted by more than 200 people about their experience of behavioural side effects of dopamine agonist drugs.

So who’s taking responsibility? We hear from pharmaceutical companies, regulators and doctors. There have been significant developments in the way these drugs are used - but what effect have they had?

Details of organisations offering help and support with some of the issues raised are available at bbc.co.uk/actionline.

If you have any concerns about medication you’re taking, speak to your doctor.
