it would be interesting to know, because some seronegative and seropositive arthritis patients can have concomittant white matter lesions that may benefit from the arthritis treatment.It is surprising how simplistic psychological medicine is.
That said they actually believe they are giving proper medical care, not terminating it.
I'm afraid i don't know what type of arthritis.
The neuropsychiatric symptoms that often go with arthritis are not necessarily correlated in severity to the disease activity, so you can have low level arthritis and higher severity of the neuropsychiatric side.
Here an example of white matter lesions in rheumatic arthritis
Results: Of the 54 participants who attended both visits (76% female, mean age 55.2 years, mean
disease duration 11.35 months at baseline), 22 (40.7%) reported a clinical
improvement in fatigue at 6 months (mean 2.64 point reduction in CFS) and 32
(60.3%) reported unchanged fatigue (-0.13 change in CFS).
Within the fatigue improver group, statistically significantly reduced FA levels were observed at
visit 2 compared to visit 1.
The regions of change were diffuse, but much greater in the right hemisphere and
specifically the periventricular, internal capsule, thalamus, inferior frontal
and parietal areas (figure). ...
In contrast, no significant differences in FA levels were observed between visits within the fatigue non-improver group.
Conclusion: The striking disparity in white matter integrity changes between the fatigue improver
and non-improver groups provides preliminary evidence to support the role of DTI as a future biomarker of RA related fatigue.
