TMS accelerato per l'apatia nel morbo di Parkinson

2 novembre 2026 aggiornato da: Medical University of South Carolina

Stimolazione Magnetica Transcranica (TMS) Accelerata per l'Apatia nella Malattia di Parkinson

This single-site, open-label pilot study will evaluate the feasibility, tolerability, and preliminary efficacy of accelerated intermittent theta-burst stimulation (iTBS) targeting the dorsomedial prefrontal cortex (dmPFC) for apathy in individuals with Parkinson's Disease (PD). Fifteen participants with PD and clinically significant apathy will undergo imaging (EEG and MRI) and one day of TMS including twelve iTBS sessions across two visits. Outcomes include adherence, tolerability, changes in apathy (Lille Apathy Rating Scale), functional engagement, and neural target engagement assessed via resting-state fMRI and EEG. Follow-up assessments will occur at one week, two weeks, and four weeks post-treatment. Fifteen participants with PD without clinically significant apathy will act as a comparison group and will undergo imaging (EEG and MRI), assessments, and questionnaires at baseline. Caregivers for each participant will complete questionnaires regarding their co-participant's symptoms as well as answer questions about their experience as a caregiver.

Descrizione dettagliata

This study is designed to explore a new treatment option for people with Parkinson's disease who experience apathy, which means loss of motivation or interest in daily activities. Apathy is common in Parkinson's disease and can lower quality of life, but current treatments are limited. Investigators are testing whether a non-invasive brain stimulation technique called repetitive transcranial magnetic stimulation (rTMS) is tolerable, acceptable and can be used to improve apathy in patients with Parkinson's disease. TMS delivers brief magnetic pulses to specific areas of the brain that are linked to motivation and decision-making. In this study, Investigators will use an "accelerated" version of TMS, which gives several short sessions in a single day, reducing the number of visits required. The purpose of this research is to see whether this treatment approach is feasible, tolerable and and potentially effective at treating apathy in people with Parkinson's disease. If successful, this research study will hopefully lead to a larger study in the future where the efficacy of the treatments can be studied.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: PD Apathetic group

Participants with Parkinson's disease and clinically significant apathy receive accelerated iTBS rTMS targeting the left dorsomedial prefrontal cortex (dmPFC) using a MagVenture MagPro system with a cooled figure-of-eight coil and Brainsight neuronavigation (slightly off midline). Resting motor threshold (rMT) is determined on the first stimulation visit (PEST) and stimulation is delivered at 120% rMT. Treatment occurs on one day, with 12 sessions separated by 10-15 min. Each session delivers 600 pulses (50 Hz triplets; 2 s on/8 s off; ~190 s), totaling 7,200 pulses overall. Coil position/angle and scalp-to-cortex distance are tracked; tolerability/acceptability (headache, pain, scalp irritation, facial twitching, fatigue, fear/anxiety) is assessed before/after sessions.
Dispositivo: Accelerated intermittent theta-burst stimulation (iTBS) rTMS to left dorsomedial prefrontal cortex (dmPFC)

Accelerated intermittent theta-burst stimulation (iTBS) rTMS to left dorsomedial prefrontal cortex (dmPFC) (MagVenture MagPro with cooled figure-of-eight coil; Brainsight neuronavigation; 120% rMT; 1 treatment day; 12 sessions; 600 pulses/session; 10-15 min inter-session interval).
Nessun intervento: Non-Apathetic PD Control Group

Participants with Parkinson's Disease without clinically significant apathy will not undergo TMS but will act as a comparison group at baseline. This group will undergo imaging (EEG and MRI), assessments, and answer questionnaires with their caregiver.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
TMS adherence
Lasso di tempo: Day 1 through Day 14 (6 treatment days over approximately 2 weeks)

Proportion of planned accelerated iTBS sessions completed. Adherence is calculated as number of iTBS sessions completed out of 48 scheduled sessions (6 treatment days × 8 sessions/day).
Day 1 through Day 14 (6 treatment days over approximately 2 weeks)
Frequency and Severity of TMS-Induced Side effects (TMS tolerability and acceptability)
Lasso di tempo: Measured during each treatment day (6 days within a 2-week period)

Participant-reported tolerability/acceptability assessed with a standardized questionnaire capturing frequency and severity of common TMS side effects (e.g., headache, pain, scalp irritation, facial twitching, fatigue, fear/anxiety), collected during treatment days (pre/post sessions).
Measured during each treatment day (6 days within a 2-week period)
Apathy severity as measured by the Lille Apathy Rating Scale
Lasso di tempo: Baseline (Day 0), immediately post-treatment (Day 14), 2 weeks post-treatment, and 4 weeks post-treatment

Change in apathy measured by the Lille Apathy Rating Scale (LARS) patient and caregiver/informant versions; analyzed as change from baseline to post-treatment and follow-up timepoints. Possible scores range from -36 to 36 with higher scores indicating greater apathy.
Baseline (Day 0), immediately post-treatment (Day 14), 2 weeks post-treatment, and 4 weeks post-treatment
Target engagement (dmPFC network modulation)
Lasso di tempo: Baseline MRI/EEG assessments (Days 0-1) and post-treatment MRI/EEG assessments (Days 14-15)
