Puri:

signifikante hersenafwijkingen

in ME/CVS

kunnen

specifieke klachten verklaren.

 

 

 

 


 

 

 

 

Puri en kollega's hebben m.b.v. de voxel-based morphometry-analysetechniek

vastgesteld dat het volume van de grijze en witte hersenstof van 26 ME/CVS-patiŽnten

op specifieke plekken signifikant minder is dan die van gezonde personen.

 

Afname van en afwijkingen in de grijze en witte hersenstof van ME/CVS-patienten

zijn eerder ook door anderen aangetoond (bijvoorbeeld: klik hier en hier).

 

Nu maar hopen dat de grijze en witte hersenstof zich iets aantrektken van CGT....

Objective:

 

It is not established

whether myalgic encephalomyelitis/chronic fatigue syndrome (CFS)

is associated with structural brain changes.

 

The aim of this study was to investigate this

by conducting the largest voxel-based morphometry study to date in CFS.

 

 

Methods:

 

High-resolution structural 3-T cerebral MRI scanning

was carried out

in 26 CFS patients and 26 age- and gender-matched healthy volunteers.

 

Voxel-wise generalised linear modelling

was applied to the processed MR data

using permutation-based non-parametric testing,

forming clusters at t > 2.3 and

testing clusters for significance at p < 0.05,

corrected for multiple comparisons across space.

 

 

Results:

 

Significant voxels (p < 0.05, corrected for multiple comparisons)

depicting reduced grey matter volume in the CFS group were noted

in the occipital lobes

(right and left occipital poles; left lateral occipital cortex,

superior division; and left supracalcrine cortex),

the right angular gyrus and the posterior division of the left parahippocampal gyrus.

 

Significant voxels (p < 0.05, corrected for multiple comparisons)

depicting reduced white matter volume in the CFS group

were also noted in the left occipital lobe.

 

 

Conclusion:

 

These data support the hypothesis that

significant neuroanatomical changes occur in CFS, and

are consistent with the complaint of impaired memory

that is common in this illness;

they also suggest that

subtle abnormalities in visual processing,

and discrepancies between intended actions and consequent movements,

may occur in CFS.
