Striatal dopamine transporter imaging correlates with anxiety and depression symptoms in Parkinson's disease
Membrane Transport Proteins
Nerve Tissue Proteins
These preliminary findings suggest that decreased DAT availability may be necessary for but not invariably associated with the development of affective symptoms in PD. This suggestion is consistent with previous research showing a link between depression and basal ganglia impairment, particularly involving the left hemisphere, and extends this finding to include anxiety.
