The Spanish Association of Alternating Hemiplegia (AESHA) is a non-profit Association which operates in the Spanish territory. The Association’s mission is to find a cure for Alternating Hemiplegia of Childhood (AHC), a rare neurological disorder which affects one in a million children.

Currently there is no cure for AHC but in 2012 the ATP1A3 gene was identified as a leading cause of AHC and represents approximately 76% of those affected. Ongoing research will hopefully provide a genetic identification for the remaining patients and a treatment for all.

Medical treatment options are extremely limited for AHC patients. The medication Flunarizine (trade name Sibelium), a calcium channel blocker, has shown some effectiveness in reducing the severity, intensity and/or duration of paralytic episodes, but is not an effective treatment in all cases.

The doctors and scientists who discovered the mutation in the gene ATP1A3 firmly believe that this disorder can be treated and, moreover, can help improve the quality of lives of millions of people with other more common disorders.

Our mission is to spread awareness of AHC, raise funds for international research programmes dedicated to the development of effective treatment and a cure, and offer support to AHC patients and their families.

Our aim is to promote a proper diagnosis, educate health professionals and the general public, as well as related organizations, exchange information with other AHC associations and make advances in the creation of an international database of all AHC patients.
