The presence of headache in Parkinson's disease has been recently reported in the literature. We studied 9cephalalgic parkinsonian patients compared to 8 parkinsonian patients taken as controls, both with clinical rating scalesand with EMG recordings of neck muscles. The presence of psychiatric disturbances was investigated by means ofseveral rating scales. Cephalalgic parkinsonian patients showed greater muscular activity and e higher degree ofanxiety and depression compared to the control group. We suggest the possibility that such factors can account for thecephalalgic condition in these patients.
