Effect of Iron on Cerebral Dopamine Receptor Density in Non-anaemic Premenopausal Women With Low Ferritin and Fatigue
Study Details
Study Description
Brief Summary
This study investigates the effect of intravenous iron substitution in non-anaemic premenopausal women with iron deficiency on:
-
Changes in the cerebral Dopamine (DA) receptor density after iron substitution, shown by brain PET
-
Reduction of fatigue and other neuropsychological symptoms after iron supplementation

Outcome Measures
Primary Outcome Measures
- Dopamine (DA) receptor density [6 weeks]
Changes in the cerebral Dopamine (DA) receptor density determined by brain PET with the 11C-Raclopride tracer
Secondary Outcome Measures
- Fatigue [6 weeks]
Reduction of fatigue after iron supplementation determined by Fatigue Assessment Scale (FAS)
- Fatigue [6 weeks]
Reduction of fatigue after iron supplementation determined by "Würzburger Erschöpfungs-Inventar bei Multipler Sklerose" (WEIMuS, in German) questionaire
- Neuropsychological symptoms [6 weeks]
Reduction of neuropsychological symptoms after iron supplementation determined by neuropsychological assessment
