Conditions: Parkinson Disease (PD), Olfactory Dysfunction
Interventions: Repetitive Transcranial Magnetic Stimulation (rTMS), Structured Olfactory Training, Sham rTMS
Countries: Turkey (Türkiye)
Background: Olfactory and gustatory impairments are common clinical manifestations in patients with neurodegenerative conditions like Parkinson's disease. These chemosensory deficits significantly impact the quality of life, often preceding motor symptoms. Currently, there is a need for effective non-invasive interventions to improve sensory recovery. Objective: The primary objective of this study is to evaluate the therapeutic efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) combined with olfactory training in restoring chemosensory function. We aim to determine whether this combined approach provides superior outcomes compared to individual therapies or standard care. Methods: This clinical trial involves 120 patients diagnosed with Parkinson's disease. Participants will be randomized into four groups to receive either combined rTMS and olfactory training, isolated rTMS, isolated olfactory training, or a control intervention. The recovery of olfactory function will be measured using validated sensory testing tools (such as Sniffin' Sticks) and Electrogustometry (EGM) to assess neural pathway improvement. Conclusion/Significance: This study aims to provide evidence-based insights into non-invasive neurological rehabilitation for chemosensory dysfunction. The findings may help optimize personalized treatment protocols for patients suffering from sensory impairment, potentially enhancing their overall cognitive and sensory quality of life.

Study type: INTERVENTIONAL
Inclusion Criteria: * Patients aged between 40 and 75 years. * Confirmed diagnosis of idiopathic Parkinson's disease (PD) according to the Movement Disorder Society (MDS) clinical diagnostic criteria. * Confirmed olfactory dysfunction validated by the Sniffin' Sticks test at baseline (defined as a composite TDI score ≤ 30.5 for hyposmia and \< 16.0 for functional anosmia).
