British Stammering Association

The British Stammering Association (BSA), trading as Stamma (styled 'STAMMA') since 2019, is a national membership organisation in the United Kingdom for adults and children who stammer, their friends and families, speech and language therapists and other professionals. It became a charity in 1978 and is based in London. The mission of the charity is to support anyone who stammers in the UK and tackle the stigma, ignorance and discrimination that people who stammer face so that they can live their lives in full and with dignity. It describes stammering as a neurological condition and estimates that up to 3% of adults in the UK have a stammer.
