Benjamin Natelson

Dr. Benjamin Natelson, is a Neurologist with post-doctoral training in Behavioral Medicine. He is head of the Pain and Fatigue Study Center in New York City which specializes in treating and researching myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), fibromyalgia (FM), and severe pain and fatigue illnesses. He is, also, an Emeritus Professor of Neurology and Neurosciences at Rutgers and Professor of Neurology at the Icahn School of Medicine at Mt. Sinai.

Dr. Natelson was one of the experts on the "Committee on the Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome" that was convened for the 2015 Institute of Medicine report.

He served as past President of the Board of Directors of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis from 2001-2003.

 * 2017, Elevations of ventricular lactate levels occur in both chronic fatigue syndrome and fibromyalgia "Abstract - 'Background: Chronic fatigue syndrome (CFS) and fibromyalgia (FM) frequently have overlapping symptoms, leading to the suggestion that the same disease processes may underpin the two disorders – the unitary hypothesis. However, studies investigating the two disorders have reported substantial clinical and/or biological differences between them, suggesting distinct pathophysiological underpinnings. Purpose: The purpose of this study was to further add to the body of evidence favoring different disease processes in CFS and FM by comparing ventricular cerebrospinal fluid lactate levels among patients with CFS alone, FM alone, overlapping CFS and FM symptoms, and healthy control subjects. Methods: Ventricular lactate was assessed in vivo with proton magnetic resonance spectroscopic imaging (1H MRSI) with the results normed across the two studies in which the data were collected. Results: Mean CSF lactate levels in CFS, FM and CFS + FM did not differ among the three groups, but were all significantly higher than the mean values for control subjects. Conclusion: While patients with CFS, FM and comorbid CFS and FM can be differentiated from healthy subjects based on measures of CFS lactate, this neuroimaging outcome measure is not a viable biomarker for differentiating CFS from FM or from patients in whom symptoms of the two disorders overlap.'"
 * 2017, Multimodal and simultaneous assessments of brain and spinal fluid abnormalities in chronic fatigue syndrome and the effects of psychiatric comorbidity"Abstract - 'The purpose of this study was to investigate whether CFS patients without comorbid psychiatric diagnoses differ from CFS patients with comorbid psychiatric diagnoses and healthy control subjects in neuropsychological performance, the proportion with elevated spinal fluid protein or white cell counts, cerebral blood flow (CBF), brain ventricular lactate and cortical glutathione (GSH). The results of the study did not show any differences in any of the outcome measures between CFS patients with and without psychiatric comorbidity, thus indicating that psychiatric status may not be an exacerbating factor in CFS. Importantly, significant differences were found between the pooled samples of CFS compared to controls. These included lower GSH and CBF and higher ventricular lactate and rates of spinal fluid abnormalities in CFS patients compared to healthy controls. Thirteen of 26 patients had abnormal values on two or more of these 4 brain-related variables. These findings, which replicate the results of several of our prior studies, support the presence of a number of neurobiological and spinal fluid abnormalities in CFS. These results will lead to further investigation into objective biomarkers of the disorder to advance the understanding of CFS.'"

 * 2000, Psychiatric Comorbidity and Somatic Distress in Sudden and Gradual Onset Chronic Fatigue Syndrome"'Abstract - The purpose of this study was to examine if type of Chronic Fatigue Syndrome (CFS) onset suggested two distinct illness patterns within CFS. One hundred and seventeen patients diagnosed with CFS by a multidisciplinary team were divided into two groups: sudden versus gradual onset of symptoms. These two subgroups were compared on the presence of lifetime comorbid Axis I diagnoses, the pattern of medically unexplained symptoms, and the number of patients who met criteria for Somatization Disorder (SD). The two subgroups did not differ in any of the experimental variables indicating that onset type is not distinguished by either comorbid psychopathology or medically unexplained symptoms. Implications of these findings are discussed.'"
 * 1998, Measurement of CO2 in Chronic Fatigue Syndrome Patients"Abstract - 'This sludy has two goals: one, to compare the resting end-tidal pCCb (PctCCh) and heart rate (HR) of chronic fatigue syndrome patients (CFS) with controls; two, to examine the effects of a mouthpiece and noseclips upon measurements of PelC02 and HR. Patients from the CFS Center came to the University Hospital pulmonary function laboratory for one testing session. Arterial (PaCCh), PetCOi, end-nasal (PenCOi) and HR were measured twice; both with and again without the subject breathing through the mouthpiece. We found that PcnCCb was greater and HR lower for both CFS and non-CFS groups when subjects were not confined by the mouthpiece. We conclude that there is no abnormality in the regulation of respiration in CFS patients. Changes in HR accompany changes in PetCOi in this study. Most likely, both result from anxiety associated with mouthpiece breathing."
