In the article (Wallace K, Uchitel J, Prange L, Jasien J, Bonner M, D'Alli R, Maslow G, Mikati MA. Characterization of Severe and Extreme Behavioral Problems in Patients with Alternating Hemiplegia of Childhood. Paediatr Neurol. 2020 Jun 27. doi: 10.1016/j.pediatrneurol.2020.06.012) published by the group of the AHC Clinic at the Duke University Medical Center, directed by Professor Mohamad Mikati, they analyzed 39 consecutive AHC patients for occurrence of behavioral problems.


  • Six (15%) patients had extreme problems defined as those present in major risk of injury to themselves or to others
  • Ten (26%) had severe problems which presented minor risk of injury to themselves or to others
  • Five (13%) had moderate problems defined as requiring intervention but presenting no risks of injury
  • Two (5%)  had mild problems defined as not requiring interventions
  • Sixteen (41%) had no behavior problems

Triggers noted in many patients 

  • peer-provocation
  • low frustration tolerance
  • limits set by others  
  • sleep disruption
  • Some medications

Reversible psychotic symptoms occurred in 2 of the 39 patients

  • In one, the trigger was trihexyphenidyl
  • In the above patient infection was a trigger on another occasion
  • In another patient, the trigger was the medication sertraline.


  • Diagnosis and therapy of coexisting neuropsychiatric diagnoses like anxiety, depression or attention deficit disorder
  • Involvement of a multidisciplinary team including mental-health professionals neurology and developmental Pediatrics
  • Medications targeting the patient’s specific problem and coexisting neuropsychiatric diagnosis and that often alpha-adrenergic agonists and SSRIs.


  • Forty one percent of AHC patients often experience severe/extreme behavioral problems
  • On rare occasions, AHC patient may have medication-triggered psychotic symptoms.
  • These correlate with the known AHC brain pathophysiology.
  • Awareness of these behavioral problems should allow anticipatory guidance and better management of such problems when they occur in some AHC patients

Data collection for the OBSERV-AHC Study (a Study of the IAHCRC Consortium) started last September 1st, in Spain, France, UK and USA, supported by their national patient associations. In Italy, they are still waiting for the approval of their Ethics Committee, but they too are ready to start as soon as they obtain it.
Data will be collected and entered in the IAHCRC-CLOUD Platform by the data-entry clinicians during the neurological visits to the patients organized in collaboration with their supporting patient associations.
The caregivers of the enrolled patients are offered the possibility to record their AHC episodes directly in the IAHCRC-CLOUD Platform, through its Mobile App, so that also their data can be included in the Study.

The technical and ethical aspects will be presented, as well as the innovative features of the IAHCRC-CLOUD Platform, making it a Second Generation Rare Disease Registry, implementing the principles and methods of patient engagement and platform cooperativism.
The current studies of the IAHCRC Consortium using the Platform will also be presented; among them, the longitudinal Study OBSERV-AHC, coordinated by the Division of Pediatric Neurology - AHC and Related Disorders Program of the Duke University in Durham, NC USA. In addition, some anticipations will be given on future developments already foreseen for the Platform, to make it an open, scalable and adaptable tool for any other rare disease.
