Fysiske fund i ME

Hvad siger de amerikanske sundhedsmyndigheder om ME? 

Amerikanske CDC fastslår på deres offentlige sundhedshjemmesider at ME er en alvorlige kronisk sygdom der påvirker mange af kroppens systemer. Karidnalsymptomet er PEM – anstrengelsesudløst symptomforværring ved mental eller fysisk aktivitet pga. mitokondrie-dysfunktion hos patienten.

Brain abnormalities
“Brain-stem hypoperfusion was confirmed in all ME/CFS patients. Patients with ME/CFS have a generalized reduction of brain perfusion, with a particular pattern of hypoperfusion of the brainstem.” Brainstem perfusion is impaired in chronic fatigue syndrome, Costa DC, Tannock C, Brostoff J.

QJM.1995 Nov;88 11):767-73
“This study provides evidence that changing motor deficits in CFS have a neurophysiological basis. The slowness of SRTs (Simple Reaction Times) supports the notion of a deficit in motor preparatory areas of the brain.“

Deficit in motor performance correlates with changed corticospinal excitability in patients with chronic fatigue syndrome,Davey NJPuri BK,Catley MMain JNowicky AVZaman R..Int J Clin Pract. 2003 May;57(4):262-4

We observed significant reductions in global gray matter volume…(which) was linked to the reduction in physical activity, a core aspect of CFS. These findings suggest that the central nervous system plays a key role in the pathophysiology of CFS and point to a new objective and quantitative tool for clinical diagnosis of this disabling disorder.

Gray matter volume reduction in the chronic fatigue syndrome, de Lange, et al. Neuroimage. 2005 Jul 1;26(3):777-81.
