NCT06676995

Brief Summary

The investigators are studying if Transcranial Pulse Stimulation (TPS) can improve various symptoms, including movement problems, thinking abilities, mood, fatigue, freezing while walking, voice quality, and issues with smell and taste. Previous research suggests TPS might help in Alzheimer's disease and could be helpful for Parkinson's as well. Investigators will check if TPS is safe, practical, and if it makes a noticeable difference in these symptoms compared to before the treatment.

Outcome Measures

Primary Outcomes (1)

  • Unified Parkinson's Disease Rating Scale (UPDRS)

    Unified Parkinson's Disease Rating Scale (UPDRS) evaluates the motor function, non-motor symptoms (mentation, behavior, and mood), activities of daily living, and complications of therapy. Each item has 0-4 ratings: 0 (normal), 1 (slight), 2 (mild), 3 (moderate), and 4 (severe). The total score can be up to 232.

    Baseline, post intervention (from enrollment to the end of intervention at 4 weeks), and follow up (after 4 weeks from the last day of intervention).)

Study Arms (1)

TPS

EXPERIMENTAL
Device: Transcranial Pulse Stimulation (TPS)

Interventions

Transcranial Pulse Stimulation (TPS) is a non invasive brain stimulation technology that applies repetitive single high-pressure ultrashort shockwave pulses within the ultrasound frequency range to stimulate the brain. Subjects will receive 12 TPS sessions conducted three times weekly, for about 40 to 50 minutes/day, over four consecutive weeks.

Eligibility Criteria

Age40 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of "probable" or "possible" PD, as defined by the current clinical criteria (52) or as confirmed by a co-investigator neurologist or confirmation via medical records or a letter from a patient's physician.
  • Age from 40 to 90 years old.
  • Disease stages 2 to 4 based on the UPDRS scale subdomain V (or Hoehn and Yahr scale).
  • Taking stable medications for PD for at least 30 days.

You may not qualify if:

  • Features suggestive of other causes of parkinsonism/Parkinson's-plus syndromes.
  • History of deep brain stimulation, brain ablation surgeries, or malignant mass brain lesions.
  • History of schizophrenia, bipolar illness, or alcohol/drug abuse within the past six months.
  • Need for rapid clinical response due to conditions such as initiation, psychosis, or suicidality.
  • Contraindications to transcranial brain stimulation (i.e., metal objects in the head, metal implanted brain medical devices, cortisone treatments within six weeks before the first stimulation session, CNS thrombosis, etc).
  • Unstable medical conditions (e.g., uncontrolled diabetes, uncompensated cardiac issues, heart failure, uncompensated pulmonary disease, or chronic obstructive pulmonary disease).
  • Contraindications to MRI according to MGB screening in the Martinos-Center (i.e., pacemaker, defibrillator or wires other than sternal wires, metallic foreign body in the eye, or drug infusion devices - if the models of these devices are not compatible with MRI).
  • Pregnancy.
  • Epilepsy or disorders that significantly increase the likelihood of seizures, including: (i) severe traumatic brain injury; (ii) congenital birth defects leading to seizures; (iii) brain tumor; (iv) metabolic disorders associated with seizures; (v) intracranial or subarachnoid hemorrhage; and (vi) non-lacunar strokes.
  • Bed- or wheelchair-bound patients.
