Study Arms (2)

Patients with parkinson's disease

Genetic analysis, clinical data , cortical excitbility

Diagnostic Test: Cortical excitability using transcranial magnetic stimulation

patients with Parkinson dementia complex

Genetic analysis, clinical data , cortical excitbility

Diagnostic Test: Cortical excitability using transcranial magnetic stimulation

Interventions

Transcranial magnetic stimulation (TMS) is a noninvasive neurophysiological technique for assessing human motor cortical function. With TMS, the underlying motor cortex is stimulated by an electric current induced by a transient magnetic field, generated in response to the passage of a large current through the stimulating coil located on the patient's scalp.

Study Population

patients with parkinson's disease and parkinson dementia complex

You may qualify if:

  • Are reliable and willing to make themselves available for the duration of the study and are willing to follow up.
  • Medically stable outpatients with confirmed diagnosis of idiopathic PD according to United Kingdom Brain Bank Criteria
  • Clear written informed consent from each participant in the trial.
  • Patients after at least 6 h free of parkinsonian drugs (off-state).
  • For the Parkinson's Dementia Complex group, dementia must be evident through history taking or clinical examination

You may not qualify if:

  • Pregnants, breastfeeding, or willing to be pregnant during the study.
  • Presence of clinically significant medical or psychiatric condition that may increase the risk associated with the study
  • Participation in any other type of medical research that may interfere with the interpretation of the study.
  • Patients with severe motor disability (bed-ridden ) that may interfere with the study procedure.
  • History of surgical or invasive intervention for Parkinson disease.
  • Patients with history of seizures or epilepsy including history in a first degree relative or patients on treatment that reduce seizure threshold.
  • For the Parkinson's Dementia Complex group, Subject with dementia due to other diseases or with Parkinson's dementia complex and contribution of other disorders (Mixed dementia)
  • Brain imaging suggesting another diagnosis.
