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
