The History of Alternating Hemiplegia of Childhood Foundation (AHCF)

From two families in Boston, the foundation has grown to discover hundreds more over the course of 30 years. Ours is a story of advocacy, passion for answers, and courage to pursue them.

June 1993 – The Early Days

Two families met at Boston’s Children’s Hospital after both their children had been diagnosed with Alternating Hemiplegia of Childhood (AHC). Kathy and Steve Hurley (Massachusetts) and Dennis and Elsie Kiernan (Virginia) thought they were the only parents with children who had AHC. From an idea at the kitchen table, they brought to fruition IFAHC, the International Foundation for Alternating Hemiplegia of Childhood. It was registered with the Commonwealth of Massachusetts.

  • Dr. Mohammad Mikati, a neurologist to both families, was interested in AHC. So he placed an ad in a medical journal looking for participants in a research study for AHC. Because of this ad, Lynn and Mark Egan (California) and Laurie and Ray Baker (Wisconsin) connected. Networking through their neurologists and Dr. Mikati, more families started to find each other.


  • Over the next two years, we continued to build our database. We knew of 36 families!
  • Dr. Mikati departed for Lebanon, and the search began for another researcher.
  • Dr. Harry Chugani from Detroit was interested in AHC and PET studies and was awarded the first grant of $19,000 to evaluate treatment approaches and the underlying cause of AHC. Patients were recruited to participate in the first AHC study of MRS and serotonin PET scans.
  • IFAHC Board and Medical Advisory Board formation
    • In April, 9 Families traveled to Detroit for the first meeting of core participants. 8 Board of Directors were elected, and 10 International Medical Advisory Board (MAB) members were confirmed.
    • New MAB members included Dr. Fred Andermann (Montreal), Dr. Kenneth Silver (Montreal), Dr. Jean Aicardi (France), Dr. Federico Vigevano (Italy), and Dr. Norio Sakuragawa (Japan).


  • Richard George created Alternating Hemiplegia Foundation (AHF). The focus of the AHF was fundraising.
  • AHF and the IFAHC jointly awarded Dr. Chugani a second grant of $30,000.
  • IFAHC created and distributed the first Newsletter.
  • Since 1988, Janssen Pharmaceuticals had been conducting a study on the efficacy of their drug Sibelium (Flunarizine) for AHC. But by the end of 1995, they could not prove Flunarizine was effective in treating AHC, nor was it cost-effective, and they discontinued the study.

1997 – First Symposium

Symposium in Woodinville, WA Parents of a newly diagnosed little girl, Laura and Kim Cooper (Washington), organized a workshop/symposium held in Woodinville, Washington, in May 1997.


  • Symposium participants included the pioneers in the field – Dr. Jean Aicardi, Dr. Fred Andermann, Dr. Eva Andermann, Dr. Harry Chugani, Dr. Diane Chugani, Dr. DaSilva, Dr. James Garbern, Dr. Giuseppe Gobbi, Dr. Renzo Guerrini Dr. Michael Johnston, Dr. Louis Ptacek, Dr. Gregory Moore, Dr. Jong Rho, Dr. Steven Roach, Dr. Harvey Sarnat, Dr. Philip Schwartzkroin, Dr. Ken Silver and Dr. Mary Zupanc.
    • The goals of the symposium were to discuss the underlying cause of AHC
    • How neurologists around the world were treating AHC,
    • What drugs were being administered,
    • National and international collaboration in studies and treatment
    • How the foundations might facilitate research.
  • A significant outcome of that meeting was the establishment of the first Biobank to collect samples from AHC patients and their families under the direction of Dr. Louis Ptacek, a neurologist, and geneticist from the University of Utah.
  • The IFAHC continued to build a database of families, launched its first website, focused on awareness through newsletters, provided family support, and conducted fundraising.


  • Dr. Kathryn Swoboda, Collected the very first familial AHC case from Boston, which she sent to Utah to launch the AHC database in 1998 in Salt Lake City. Dr. Swoboda wrote an NIH grant and received a K award to work on the AHC Database project. She also received a grant from the Dystonia Medical Research Foundation to get additional funding to begin collecting clinical records and blood samples from patients and their parents making cell lines

1999 – 2000

. First ‘Midwest Family Gathering’

  • June 1999 – organized by the Prunty and Ryan families in Rockford, Illinois. Fourteen families attended, including grandparents from WI, MN, OH, MI, and IL. Dr. Silver gave a presentation on AHC and answered questions. Grant proposals were discussed, and a successful DNA collection was held, but the highlight was the children meeting each other for the first time, ages ranging from toddler to teenager!
  • There were now 206 families that we knew of worldwide!!
  • In June 2000, the second ‘Midwest Family Gathering’ was held.
  • The AHF funded two research grants for $77,485.00 to Dr. Louis Ptacek, “Toward a Molecular Understanding of AHC” and “The Effects of Flunarizine of Neocortical GABAergic and Glutamatergic Function, to ”Drs. Johannes van Brederode and Jong Rho.
  • Lynn Egan became President of IFAHC in 2000.

2001 – The Merge of IFAHC and AHF

  • The IFAHC and AHF had worked together for eight years. In March 2001. It was decided to become one organization and combine resources. As a result, the Alternating Hemiplegia of Childhood Foundation (AHCF) was established.
  • Dr. Ptacek left in 2001, and the AHC Gene Project transitioned to a completely independent neurogenetics laboratory at the University of Utah.

2003 – 2010

  • In 2003, families traveled to Salt Lake City for another family meeting. Even in these early years, it was evident that Family meetings played an essential role in the lives of the AHC families.
  • International Collaboration A measure of the growing interest of AHC internationally was the collaboration between scientists in Los Angeles, Boston, Italy, and France.
  • In 2003, AHCF awarded Dr. Swoboda $66,890.00 each year for the next three years to identify the genetic cause of Alternating Hemiplegia of Childhood
