Physiopathology of neurological disorders Main domain : Cellular & molecular neurosciences Subdomain : Clinical & translational neurosciences
Alexandra DURR’s team focus on neurogenetic diseases, spinocerebellar degenerations – SCD (spastic paraplegias and cerebellar ataxias), frontotemporal lobar degenerations – FTLD and Huntington disease. These rare conditions share clinical, genetic and functional characteristics but are extremely heterogeneous both in molecular and clinical aspects.
