Abstract
Disabling fatigue is a symptom in a number of neurological diseases, including multiple sclerosis, stroke and Parkinsons disease. We used 18F-dopa and 11C-DASB [N,N-dimethyl-2-(2-amino-4-cyanophenylthio) benzylamine] positron emission tomography, markers of dopamine storage capacity and serotonin transporter availability, to investigate whether fatigue in Parkinsons disease is associated with dopaminergic and serotonergic dysfunction in basal ganglia and limbic circuits. Ten patients with Parkinsons disease and fatigue and 10 patients without fatigue had a 18F-dopa scan. Seven patients with and eight patients without fatigue also had a 11C-DASB scan. The two groups were matched for age, disease duration and severity and daily intake of levodopa equivalent units. None had a history of depression or sleep disturbance. Using a region of interest analytical approach, we found that patients with fatigue had significantly lower serotonin transporter binding than patients without fatigue in the caudate, putamen, ventral striatum and thalamus. Striatal 18F-dopa uptake was similar in the fatigued and non-fatigued groups. Voxel-based analysis localized further relative serotonin transporter binding reductions in the cingulate and amygdala of the fatigue group, and 18F-dopa uptake reductions in the caudate and insula. We conclude that fatigue in Parkinsons disease is associated with reduced serotonergic function in the basal ganglia and limbic structures. Insular dopaminergic dysfunction could also play a role. These findings imply that strategies to increase brain level of serotonin would be a rational approach for relieving fatigue symptoms in Parkinsons disease and may also be relevant to alleviating fatigue in other clinical conditions.
