Brief Summary

Pain (spontaneous pain) is a fundamental non-motor symptom (NMS) of Parkinson's disease (PD) that is prevalent throughout the condition and often unrecognized and undertreated. The study of the scalp laser-evoked potentials (LEPs) (evoked pain) allows a non-invasive exploration of pain central pathways in humans. This technique proved useful in elucidating the physiopathology underlying different pain syndromes. This study has been conceived to study spontaneous pain (and/or evoked pain by laser stimulation) in PD patients (with or without pain) with motor fluctuations under drugs-on (Safinamide Metansolfonato or Rasagilina Mesilato).

Outcome Measures

Primary Outcomes (4)

  • Latency (ms) of N1/P1 complex.

    Laser-evoked potentials (LEPs) to explore the primary pain pathway will be assessed at each visit (V0 and V1). The technique of LEPs recording will be carried out as previously performed by our research group.

    Change from baseline at 12 weeks

  • Latency (ms) of N2/P2 complex.

    Laser-evoked potentials (LEPs) to explore the primary pain pathway will be assessed at each visit (V0 and V1). The technique of LEPs recording will be carried out as previously performed by our research group.

    Change from baseline at 12 weeks

  • Amplitude (microvolt) of N1/P1 complex.

    Laser-evoked potentials (LEPs) to explore the primary pain pathway will be assessed at each visit (V0 and V1). The technique of LEPs recording will be carried out as previously performed by our research group.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Males or females patients with mid-to-late PD aged 30 to 80 years with or without chronic pain symptoms (duration \>3 months) and motor fluctuations while receiving L-dopa alone or with other dopaminergic treatments.

You may qualify if:

  • PD patients with or without pain willing to participate in this study and able to sign the written informed consent
  • To be included in the PD with pain group, the patient's intensity of pain must be moderate to severe over the last month, as reported by a numerical rating scores (NRS≥4) despite the optimal dopaminergic treatment
  • No modification of dopaminergic drugs and analgesic therapy with FANS during the 28 days before starting the enrollment in this study.
  • Diagnosis of idiopathic PD of ≥3 years duration
  • Hoehn and Yahr stage I-III during OFF time
  • Motor fluctuations (\>1.5 hours' OFF time/day)
  • Patients who would have been treated with add-on therapy irrespective to the present protocol

You may not qualify if:

  • Patients under (or with previous assumptions) monoamine oxidase inhibitor therapy.
  • Late-stage PD experiencing severe, disabling peak-dose or biphasic dyskinesia, or unpredictable or widely swinging symptom fluctuations
  • "de novo" patients, patients in early stage or non-fluctuating patients
  • Evidence of dementia (MMSE \<24)
  • Sign and symptoms suggestive of atypical parkinsonism
  • Major psychiatric illnesses
  • Severe and progressive medical illnesses
  • Concomitant diseases potentially causing acute or chronic pain (i.e., rheumatologic conditions, severe polyneuropathy, and spine injuries)
  • Treatments with tri-tetracyclic antidepressants, serotonin-norepinephrine reuptake inhibitors (SNRIs), opioids, neuroleptics, barbiturates and phenothiazines, pregabalin and gabapentin
  • Any type of retinopathy
