Previous studies had also confirmed this brain cell loss but up until now scientists had believed that the damage was only temporary.

"In general, we've always assumed full recovery of cognition following short and long-term sleep loss," said lead author Prof Sigrid Veasey. "But some of the research in humans has shown that attention span and several other aspects of cognition may not normalize even with three days of recovery sleep, raising the question of lasting injury in the brain."
