Impulsive: Omnibus (part 1)

Early in 2025, BBC Investigations Correspondent Noel Titheradge published his first story about a category of prescription drug with unusual side effects.

People who take dopamine agonist drugs for conditions like Parkinson’s disease or Restless Legs Syndrome often report impulse control disorders - problems with gambling, compulsive eating or shopping, or hypersexuality.

He wasn’t expecting the response. After that first article was published more than 200 people got in touch - that’s me, they said, that’s my partner, that’s my dad.

So Noel started digging.

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