Is sympathetic overactivity due to sleep fragmentation associated with elevated diurnal systolic blood pressure in healthy elderly subjects : the PROOF-SYNAPSE study?
In healthy elderly subjects, repetitive sympathetic arousals during sleep are associated with elevated systolic BP and higher risk of hypertension, after controlling for confounders. Sympathetic overactivity is the proposed underlying mechanism.
Parent history of pain and pain-related cognitions may contribute to adolescent risk for chronic pain.
