Placebo administration is known to affect the brain both in pain and in Parkinson disease. Here we show that placebo treatment caused reduced activity in single neurons in the subthalamic nucleus of placebo-responsive Parkinsonian patients. These changes in activity were tightly correlated with clinical improvement; no decrease in activity occurred when the(More)
Unilateral cranial autonomic symptoms (UAs) such as lacrimation, conjunctival injection, eyelid oedema and nasal congestion, which are the hallmark of trigeminal autonomic cephalgias, may also occur in an as yet undetermined proportion of migraine patients. We studied 177 consecutive migraineurs to assess the frequency of UAs and the clinical(More)
OBJECTIVE This study reports a retrospective analysis of 67 consecutive parkinsonian patients to assess changes in antiparkinsonian medications after Deep Brain Stimulation (DBS) of the Subthalamic Nucleus (STN). METHODS All antiparkinsonian drugs, including levodopa, dopamine agonists, associated drugs such as COMT and MAO inhibitors, amantadine and(More)
OBJECTIVES To evaluate changes in sexual well being in a group of patients with Parkinson's disease following deep brain stimulation (DBS) of the subthalamic nucleus (STN). METHODS 31 consecutive patients with Parkinson's disease (21 men and 10 women), bilaterally implanted for DBS of STN, were evaluated one month before and 9-12 months after surgery.(More)
OBJECTIVE To investigate the response to sumatriptan in migraineurs with unilateral cranial autonomic symptoms such as lacrimation, eye redness, eyelid edema, nasal congestion, and rhinorrhea. BACKGROUND Given the potential large-scale recruitment of peripheral neurovascular 5-HT1B/1D receptors consequent to the activation of the trigeminal autonomic(More)
BACKGROUND Neuro-psychiatric (NP) disturbances are highly prevalent in patients with Parkinson's disease (PD) and contribute to worsen quality of life. Deep brain stimulation of the subthalamic nucleus (STN-DBS) is commonly utilized as surgical treatment for advanced PD with motor complications. The effectiveness of the procedure on motor symptoms is well(More)
