Growing evidence supports sleep-wake disruption as a mechanism involved in mood disorders pathogenesis. Duration of depressive episodes varies widely, and longer depressive episodes have been connected to worse outcomes. We aimed to explore if the length of depressive episodes is related to objective modifications of sleep features.

Although several studies have highlighted cellular dysfunctions in neurons, there is limited information on the effects of FXN depletion in astrocytes and on the potential non-cell autonomous mechanisms affecting neurons in FRDA. In this study, we generated a model of FRDA cerebellar astrocytes to unveil phenotypic alterations that might contribute to cerebellar atrophy.
