Popis: Objectives – The purpose of this study was to investigate whether dopamine D2 receptor binding was altered in the striatum of essential blepharospasm patients. Methods – Striatal dopamine D2 receptor binding was measured with positron emission tomography and [11C]raclopride. We studied eight drug-naive patients with bilateral blepharospasm and eight age-matched normal controls. Results – The uptake indices in the blepharospasm group were significantly reduced by 11.7% in the caudate (P
