“…As the first generation of ELBW survivors looks ahead towards middle-age, any pre-existing PNS vulnerability in this group is likely to be compounded by normal age-related declines in parasympathetic functioning (Umetani et al, 1998) and physical fitness (DeMeersman & Stein, 2007), age-related increases in blood pressure variability (Uchino, Berg et al, 2006), and the potential development of cardiac risk factors such as atherosclerosis. In these cases, interventions such as aerobic exercise (e.g., Sloan, Shapiro et al, 2009) or biofeedback (e.g., Abukonna, Yu et al, 2013) may be warranted to support RSA levels over the long term.…”

Individuals born at extremely low birth weight (ELBW; < 1000 grams) are exposed to early adversity in multiple forms. Given that substantial development of the autonomic nervous system (ANS) occurs during the third trimester of gestation, ANS functioning may be altered in adults who were born before reaching 28 weeks of gestational age. The aims of the study were to: 1) determine whether two indices of ANS functioning [resting heart period (HP) and respiratory sinus arrhythmia (RSA)], differed between adult ELBW survivors and normal birth weight (NBW) controls, and 2) ascertain whether ANS functioning was differentially vulnerable to age-related decline in the ELBW participants. Resting HP and RSA (reflecting cardiac efficiency and responsive cardiac control, respectively) were assessed in 30 non-impaired ELBW survivors and 47 NBW controls at age 22-26 and again at 30-35 years. At each assessment, resting RSA was significantly lower in the ELBW group than in the NBW comparison group. In addition, individual differences in RSA within the ELBW group were poorly preserved over time. These findings are suggestive of a premature decline in parasympathetic functioning in some adult ELBW survivors.

“…The biofeedback literature most often argues that observed effects are due to volitional control of biological variables (e.g., Abukonna, Xiaolin, Zhang, & Zhang, 2013), and neurofeedback is known to be more efficient when based on volitional and conscious cognitive strategies demanding the use of attentional processes (Bagdasaryan & Le Van Quyen, 2013). However, one could argue that improved regulation could be achieved without volitional control (in which case the subject would not exert voluntary control over the regulation).…”

“…Decreased HR is often interpreted as sympathetic depression (Abukonna et al 2013), but it may also be due to increased parasympathetic activity and is closely linked with arterial BP and baroreflex sensitivity (Taylor et al 2015). Acute elevation of BP (unlike the chronic condition of hypertension) is considered to be primarily mediated by noradrenergic ganglionic pathways in the sympathetic nervous system (Guyenet 2006), and diastolic resting BP is a good measure of barosensitive sympathetic regulation (Joyner et al 2010).…”

Sivakumar SS, Namath AG, Tuxhorn IE, Lewis SJ, Galán RF. Decreased heart rate and enhanced sinus arrhythmia during interictal sleep demonstrate autonomic imbalance in generalized epilepsy. J Neurophysiol 115: 1988 -1999. First published February 17, 2016 doi:10.1152/jn.01120.2015.-We hypothesized that epilepsy affects the activity of the autonomic nervous system even in the absence of seizures, which should manifest as differences in heart rate variability (HRV) and cardiac cycle. To test this hypothesis, we investigated ECG traces of 91 children and adolescents with generalized epilepsy and 25 neurologically normal controls during 30 min of stage 2 sleep with interictal or normal EEG. Mean heart rate (HR) and high-frequency HRV corresponding to respiratory sinus arrhythmia (RSA) were quantified and compared. Blood pressure (BP) measurements from physical exams of all subjects were also collected and analyzed. RSA was on average significantly stronger in patients with epilepsy, whereas their mean HR was significantly lower after adjusting for age, body mass index, and sex, consistent with increased parasympathetic tone in these patients. In contrast, diastolic (and systolic) BP at rest was not significantly different, indicating that the sympathetic tone is similar. Remarkably, five additional subjects, initially diagnosed as neurologically normal but with enhanced RSA and lower HR, eventually developed epilepsy, suggesting that increased parasympathetic tone precedes the onset of epilepsy in children. ECG waveforms in epilepsy also displayed significantly longer TP intervals (ventricular diastole) relative to the RR interval. The relative TP interval correlated positively with RSA and negatively with HR, suggesting that these parameters are linked through a common mechanism, which we discuss. Altogether, our results provide evidence for imbalanced autonomic function in generalized epilepsy, which may be a key contributing factor to sudden unexpected death in epilepsy.SUDEP; heart rate variability; cardiac cycle; parasympathetic tone; children EPILEPTIC SEIZURES ARE KNOWN to have profound effects on autonomic function (Wyllie 2015). To quantify these effects, many studies have focused on heart rate (HR) (Behbahani et al.
