What this trial studies

This randomized interventional trial will assign adults with Parkinson's disease undergoing bilateral subthalamic nucleus DBS to either Mediterranean diet guidance for three months or to continue their usual diet. Researchers will measure body weight, body composition, nutritional status, appetite, quality of life, and physical activity before and after the intervention. Eligible participants are 45–64 years old, have a Mini Mental State Examination score ≥24, and continue their antiparkinsonian medications. The trial is conducted at Ankara Etlik City Hospital and focuses on post-surgical dietary management to limit weight gain commonly seen after DBS.

Who should consider this trial

Good fit: Ideal candidates are adults aged 45–64 with Parkinson's disease scheduled for or having undergone bilateral STN DBS who have MMSE ≥24 and can follow dietary guidance while continuing antiparkinsonian therapy.

Not a fit: Patients with psychiatric illness, cognitive impairment (MMSE <24), or medical conditions requiring a special diet are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the Mediterranean diet could reduce post-DBS weight gain and improve body composition, appetite, nutritional status, and overall quality of life.

How similar studies have performed: The Mediterranean diet has documented metabolic and general health benefits and has been associated with better outcomes in some Parkinson's cohorts, but using it specifically to prevent weight gain after STN DBS is relatively novel and not well established.
