Cavernoma Alliance UK (also known as CAUK) is a charity created for people affected by cavernoma – otherwise known as cerebral cavernous malformation (CCM); cavernous haemangioma;  or cavernous angioma. Our mission is to improve the quality of life for all those affected and create greater awareness of the condition.

A cavernoma is an abnormal raspberry-shaped mass of blood capillaries in the brain or spine. Around 1 in 625 people have a cavernoma. Symptomatic cavernoma are rare (c.1/12,500). When symptoms do occur they can be serious, life changing and severely debilitating: strokes, seizures, partial or full paralysis, sight, speech or hearing problems as well as other serious symptoms. Around 200–300 people are diagnosed per annum in the UK.
