Only the individual rare diseases are rare, all together they are extremely numerous. So far, between 6000 and 8000 rare diseases have been described worldwide. Most of them have hardly been researched, and new ones are added practically every day. In Switzerland and Europe, a disease is considered rare if it affects no more than five out of 10,000 people.

The Swiss Neurological Society (SNS) pools expert knowledge in an interdisciplinary way together with partner societies, in the sense of a strong neurology. For more information, see the SNS media release on International Rare Disease Day here.
