Objective: To examine the association between migraine and syncope-related autonomic nervous system (ANS) symptoms.Methods: A population-based study among migraineurs with and without aura (n = 323) and control subjects (n = 153) was conducted. A systematic questionnaire and cardiovascular measurements during rest, while standing, and after venipuncture addressed the prevalence of syncope, orthostatic intolerance, orthostatic hypotension (OH), and the postural tachycardia syndrome (POTS) in migraineurs and control subjects.Results: The lifetime prevalence of syncope in all participants was 41%, more often in women (45 vs 32%; p = 0.02). Compared with control subjects, migraineurs had a higher lifetime prevalence of syncope (46 vs 31%; p = 0.001), frequent syncope (five or more attacks) (13 vs 5%; p = 0.02), and orthostatic intolerance (32 vs 12%; p < 0.001). There was no association between ANS symptoms and the severity of migraine or migraine subtype. Cardiovascular measurements and the prevalence of POTS and OH did not differ significantly between migraineurs and control subjects.Conclusion: This population-based study demonstrated an elevated prevalence of syncope and orthostatic intolerance in migraineurs without clear interictal signs of autonomic nervous system dysfunction.

Background: Caring for a loved one can be rewarding but also associated with substantial caregiver burden, developing mental outcomes and affecting happiness. Eventually, these physical and psychological disorders can lead to an imbalance of the autonomic nervous system. Meditation has been found to offer multiple benefits to relieve these disorders and reduce the risk of cardiovascular disease. The aim of this study was to determine the effects of a four-week 16-hour presential meditation program on physiological and psychological parameters and vagal nerve activity in high-burden caregivers, comparing the results with those not receiving this program. Methods: A non-randomized repeated-measures controlled clinical trial was conducted, dividing participants between intervention and control groups by convenience allocation because random assignment was ethically inappropriate. Results: After the meditation program, the experimental group showed a significant reduction in anxiety levels (F= 24.92, p&lt;0.001), a non-significant amelioration of depression levels (F= 1.75, p=0.19), and significantly improved heart rate variability (F= 8.40, p&lt;0.05) and SDNN (F=15.59, p&lt;0.05). Conclusions: Meditation can be a useful therapy to enhance the mental health and autonomic nervous system balance of informal caregivers, improving symptoms of physical and mental overload.

Nervous System Function

Objective. Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder in which many cardinal features may have a neurologically based patho-physiology involving both the central and peripheral components of the autonomic nervous system. Autonomic nervous system function was studied noninvasively in a group of subjects with PWS and control subjects to determine whether autonomic nervous system dysfunction exists as part of the PWS. Design/setting. This cross-sectional study was performed in the neurophysiology laboratory at a tertiary care facility. Methods. Evaluation included anthropometric measurements and calculation of a body mass index (BMI). Simultaneous electrocardiography and serial recordings of pulse rate and systolic/diastolic mean arterial blood pressures during orthostatic maneuvers were taken. Pupillary response to the instillation of dilute pilocarpine and measurements of plasma norepinephrine at rest and after standing were also obtained. Results were analyzed using two-tailed t tests, Fisher exact test, analysis of variance, and analysis of covariance adjusting for age, gender, and BMI. Patients. There were 14 subjects with PWS (8 female, 6 male; aged 4 to 40 years, mean age 16 years) and 8 control subjects (4 female, 4 male; aged 5 to 37 years, mean age 19 years). Results. Abnormal findings were obtained only in subjects with PWS. Analysis of covariance adjusting for age, gender, and BMI revealed a trend for subjects with PWS to have lower resting diastolic blood pressure (P &lt; .09) and significantly less change in diastolic blood pressure after standing (P &lt; .02). Subjects with PWS had significantly greater BMI than did control subjects (P &lt; .001), which correlated significantly with all pulse rate measurements where the greater the BMI the higher the pulse rate at rest (r = .25, P &lt; .04) and the lower the pulse rate after arising from lying to standing at both 15 and 30 seconds (r = .17, P &lt; .1; r = .55, P &lt; .08 respectively). Pupillary constriction of 2 mm or more was seen in 7 of 14 subjects with PWS and in no control subjects (P &lt; .004). The 30:15 R-R interval ratio was abnormal in 6 of 14 subjects with PWS and in no control subjects (P &lt; .03). Conclusions. These results suggest that patients with PWS have a detectable underlying autonomic dysfunction characterized principally by diminished parasympathetic nervous system activity.

Autonomic Nervous

Type 2 diabetes (T2D) and ageing have well documented effects on every organ in the body. In T2D the autonomic nervous system is impaired due to damage to neurons, sensory receptors, synapses and the blood vessels. This paper will concentrate on how autonomic impairment alters normal daily activities. Impairments include the response of the blood vessels to heat, sweating, heat transfer, whole body heating, orthostatic intolerance, balance, and gait. Because diabetes is more prevalent in older individuals, the effects of ageing will be examined. Beginning with endothelial dysfunction, blood vessels have impairment in their ability to vasodilate. With this and synaptic damage, the autonomic nervous system cannot compensate for effectors such as pressure on and heating of the skin. This and reduced ability of the heart to respond to stress, reduces autonomic orthostatic compensation. Diminished sweating causes the skin and core temperature to be high during whole body heating. Impaired orthostatic tolerance, impaired vision and vestibular sensing, causes poor balance and impaired gait. Overall, people with T2D must be made aware and counseled relative to the potential consequence of these impairments.
