Nice summary of the different anti-depressants to have on hand. I need to take this into account in my studies! Reminder: paroxitine = Paxel Fluoxitine = Prozac Citalopram= Celexa Sertaline=Zoloft Escitalopram= Lexapro Psychosom Med. 2016 May 23. Differential Associations of
This study Identifies particular brain regions involved in the decrease in parasympathetic activity (HF HRV) with experimentally induced pain. Neuroimaging brainstem circuitry supporting cardiovagal response to pain: a combined heart rate variability/ultrahigh-field (7 T) functional magnetic resonance imaging study Roberta
Article about vagus nerve stim and the different devices and companies that are promoting them
Part of the ongoing collection of posts about transcutaneous vagal nerve stim. Full article here. Non-invasive Access to the Vagus Nerve Central Projections via Electrical Stimulation of the External Ear: fMRI Evidence in Humans Brain Stimul. 2015 May-Jun;8(3):624-36. doi: 10.1016/j.brs.2014.11.018.
In this article, they didn’t see much difference between migraineurs and controls except in possibly more sympathetic response to stressors. I would agree with that, given what I’ve seen in the clinic. I can’t account for the fact that
In this study, again, we see blunted autonomic response to stress invoking activity in youngsters with social anxiety compared to healthy controls. Their tonic sympathetic activity is higher, and their parasympathetic lower than in healthy controls. Eur Child Adolesc Psychiatry.
In this study, they find that subjects most likely to respond show a decrease in their HF (parasympathetic activity) during exposure to the stressor, that then goes back to baseline. The subjects less likely to respond show a more rigid
In digging in deeper to patients responsiveness to treatment and physiological profiles, it is starting to get less intuitive. For example, this study shows that baseline increase in heart rate in patients with claustrophobia correlates with likelihood to respond to
Okay. In this study, they show that eating disorder women show not only blunted HPAA activity, but INCREASED parasympathetic activity. I think I’ve chosen a very poor topic to devote my research to. Too many variables!! J Psychosom Res. 2015
Another study looking at reactivity, or response instead of steady state measures to stratify clinical response. The relaxation response I first noticed with acupuncture may be getting at this same type of phenomenon. Unfortunately, in their study, they don’t report
