Can I reverse brain damage from sleep deprivation?
Brain damage caused by severe sleep apnea is reversible. This brain damage was accompanied by impairments to cognition, mood and daytime alertness. Although three months of CPAP therapy produced only limited improvements to damaged brain structures, 12 months of CPAP therapy led to an almost complete reversal of white matter abnormalities.
