Did Leng et al. consider pre-existing brain injury due to head trauma or previous cerebrovascular incidents as the cause of prolonged sleep? This would make sense, as these conditions increase the risk of stroke. Similarly, did the authors investigate potential cognitive deficits in the excess sleep group? This could predict chronic organic brain disease such as a dementing illness. Finally, Have the authors excluded the effect of sleep disorders such as obstructive sleep apnea?
