Support to the ResearchThe I.B.AHC Project
I.B.AHC – Biobank and Clinical Registry for Alternating Hemiplegia is a project coordinated and funded by A.I.S.EA Onlus, in collaboration with its Scientific Committee and with the Biomolecular Laboratory of the Scientific Institute “E. Medea”
I.B.AHC is composed of two main repositories, the Clinical Registry and the Biological Bank (Biobank), designed to collect, organize, keep and share both the clinical data and the biological samples (DNA, RNA and Cellular Lines) of the patients affected by AHC.
(40.000 € for the development of the on-line Registry + 60.000 € for the personnel costs + 30.000 € for the data collection)

The I.B.AHC Biobank and Clinical Registry are
Open to all research projects, with these characteristics:
Only on AHC Non lucrative Good quality and not duplicated

Quality of Life “Alternating Hemiplegia: a study of the paroxysmal episodes”, by E. De Grandis, M. Giannotta, E. Veneselli, F. Franchini, R. Vavassori (2011 – 2012) aim of the study is to collect at a large scale,
information about paroxysmal episodes (trigger factors, frequency, management, treatment)
The collected data will be scientifically validated and analyzed.
Expected results: to better document paroxysmal episodes in AHC, to provide practical suggestions on how to manage episodes and to ameliorate the quality of life in AHC, as regards to treatment, psychological support, supportive and educational therapy, patients’ needs.
