This European organisation needs your help

We would like to invite you to take part in our new survey on the journey to diagnosis for people living with a rare disease.

Take the survey

It should take no more than 20 minutes to complete and closes on 15 June 2022.

Obtaining a diagnosis can be a long and difficult journey for both patients and their families. By asking questions on the support you had, the difficulties you encountered, or on the consequences of being undiagnosed or misdiagnosed, we will be able to better identify how to improve the diagnosis journey of people living with rare diseases.

Fund Raising





My name is Amy Bennison.  I am 10 years old and live near York.  I was diagnosed with CVS when I was 3 and I have regular sickness episodes about 5 times a year.  My Grandma is really good at knitting and sewing.  She made loads of handcrafted items throughout the year and had a Christmas stall.  She raised a fabulous £250 for CVSA but not only that, she spread the word about CVS.  Lots of people at the stall were very interested and surprised to hear about CVS.  Well done to my fantastic Grandma.
