Cerebral blood flow and heart rate variability in CFS
Cerebral blood flow and heart rate variability in Chronic Fatigue Syndrome: a randomized cross-over study, by Anneleen Malfliet, Roselien Pas, Raf Brouns, Joris De Win, Samar M Hatem, Mira Meeus, Kelly Ickmans, Robbert-Jan van Hooff, and Jo Nijs in heart 2018; 21:E13-E24 BACKGROUND: Pain, fatigue, and concentration difficulties … Continue reading
Increase in the Regional Cerebral Blood Flow following Waon Therapy in Patients with CFS
Research abstract: Increase in the Regional Cerebral Blood Flow following Waon Therapy in Patients with Chronic Fatigue Syndrome: A Pilot Study, by T Munemoto, Y Soejima, A Masuda, Y Nakabeppu, C Tei, in Intern Med. 2017;56(14):1817-1824 [Epub 2017 Jul 15] Objective: … Continue reading
Brain & spinal fluid abnormalities in CFS are not affected by psychiatric comorbidity
Research highlights: As a group, CFS patients have higher brain ventricular lactate, more abnormal spinal fluid results, lower brain GSH, and reduced cerebral blood flow relative to healthy sedentary controls Psychiatric comorbidity does not influence any of these potential biological … Continue reading
Abnormal cerebral blood flow found in ME/CFS by ASL fMRI
Research abstract: BACKGROUND Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating disorder characterized by severe fatigue and neurocognitive dysfunction. Recent work from our laboratory and others utilizing arterial spin labeling functional magnetic resonance imaging (ASL) indicated that ME/CFS patients have … Continue reading
Abnormal blood flow & connectivity found in ME/CFS brains
Research abstract: Although altered resting-state functional connectivity is a characteristic of many chronic pain conditions it has not yet been evaluated in patients with chronic fatigue. Our objective was to investigate the association between fatigue and altered resting-state functional connectivity … Continue reading
Cerebral blood flow & impaired neurocognition in POTS
Research abstract We hypothesize that upright cognitive impairment in patients with postural tachycardia syndrome (POTS) is caused by reduced cerebral blood flow (CBF). The CBF velocity (CBFv) measured by transcranial Doppler ultrasound decreased excessively during 70° tilt in a minority … Continue reading
Poor blood flow leads to cognitive problems in FM
Abstract Objective: There is ample evidence for cognitive deficits in fibromyalgia syndrome (FMS). The present study investigated cerebral blood flow responses during arithmetic processing in FMS patients and its relationship with performance. The influence of clinical factors on performance and … Continue reading
Reduced blood flow following reduced nitrergic nitric oxide in POTS
Abstract Cognitive deficits are characteristic of postural tachycardia syndrome (POTS). Intact nitrergic nitric oxide (NO) is important to cerebral blood flow (CBF) regulation, to neurovascular coupling, and to cognitive efficacy. POTS patients often experience defective (NO) mediated vasodilation caused by … Continue reading
Blood flow increases in the brain in POTS
Abstract Decreased upright cerebral blood flow (CBF) with hyperpnea and hypocapnia is seen in a minority of patients with postural tachycardia syndrome (POTS). More often, CBF is not decreased despite upright neurocognitive dysfunction. This may result from time-dependent changes in … Continue reading
