Comment on: Possible upregulation of hypothalamic 5-hydroxytryptamine receptors in patients with postviral fatigue syndrome. [BMJ. 1992]
EDITOR, -A M 0 Bakheit and colleagues recently reported’ a possible upregulation of hypothalamic 5-hydroxytryptamine receptors in patients with the postviral fatigue syndrome, giving some evidence for hypothalamic functional abnormalities in these patients, which are different from others with depression. There is a growing body of evidence which claims that this clinical condition is organic and cannot be simply perceived as a somatisation disorder in patients with predisposition to psychiatric disease.”
We reviewed and quantitatively analysed with Ceretec and single photon emission tomography the brain perfusion of 14 patients fulfilling the Oxford criteria for diagnosis of myalgic encephalomyelitis. They had all had disease for more than six months (more than half the time) manifested with generalised malaise and myalgia, as well as significant physical and intellectual disability. None had any medical condition known to produce fatigue or had recently or in the past had psychiatric disease. When compared with a group of 24 nondepressed age and sex matched controls (normal volunteers) there was significant reduction of the perfusion to several areas of the brain cortex but particularly the brain stem (table).
