Ketogeen Dieet en Neuromodulatie bij Behandelresistente Depressie (ALIGN)
Adjunctief koolhydraatarm ketogeen dieet om beeldgeleide neuromodulatie te verbeteren bij therapieresistente depressie
Het doel van dit klinisch onderzoek is om te testen of het combineren van een ketogeen dieet (KD) met gepersonaliseerde, versnelde intermitterende theta burst stimulatie (iTBS) grotere verminderingen van depressieve symptomen oplevert dan iTBS gecombineerd met een standaard gezond dieet bij volwassenen met therapieresistente depressie. De proef heeft ook tot doel te bepalen of deelnemers een ketogeen dieet haalbaar kunnen volgen tijdens een versnelde iTBS-behandelingskuur en of het dieet meetbare veranderingen in ketonenniveaus produceert.
Specifiek heeft de studie tot doel te bepalen of de gecombineerde interventie:
- Depressieve symptomen vermindert
- De circulerende ketonenniveaus verhoogt
- Haalbaar en draaglijk is tijdens versnelde iTBS-behandeling
Deelnemers beginnen met een KD of een dieet volgens de Canadese voedselgids (CFGD) met een 3-weken durende dieetvoorbereidingsperiode, waarna ze een kuur van gepersonaliseerde, versnelde iTBS ondergaan terwijl ze hun toegewezen dieet voortzetten. Voor en na de iTBS-behandelingskuur zullen deelnemers klinische beoordelingen voltooien, bloedmonsters afgeven voor metabolische tests en MRI-scans ondergaan om de hersenconnectiviteit te beoordelen. Ketonenniveaus worden dagelijks gemeten gedurende de 15-weken durende dieetinterventie. Binnen-groep en tussen-groep verschillen worden vergeleken om veranderingen in klinische uitkomsten, metabolisme en hersenfunctie te karakteriseren.

|---|---|
|
Experimenteel: Ketogenic Diet
Participants in this arm will follow a well-formulated ketogenic diet (low carbohydrate, moderate protein, high fat) for a 3-week dietary lead-in period prior to neuromodulation, and will continue the diet for a total of 12 weeks.
The diet is designed to achieve and maintain nutritional ketosis (blood ketone levels of 0.5 to 3 mmol/L).
Dietitian support will be provided through scheduled counseling and ongoing monitoring of finger-stick ketone and glucose testing.
|
Intermittent theta burst stimulation (iTBS), a form of repetitive transcranial magnetic stimulation (rTMS), is a non-invasive brain stimulation technique approved by the FDA and Health Canada for the treatment of TRD.
In this study, participants will receive an accelerated course of imaging-guided, neuronavigated left dorsolateral prefrontal cortex (DLPFC) iTBS targeted based on functional connectivity with the subgenual anterior cingulate cortex (sgACC).
Stimulation protocol consists of 1800 pulses per session, delivered at 110% of resting motor threshold, with 50-minute inter-session intervals, for 8 sessions per day over 5 consecutive days.

Actieve vergelijker: Canadian Food Guide-Aligned Diet
Participants in this arm will follow a Canadian Food Guide-aligned diet for a 3-week dietary lead-in period prior to neuromodulation and will continue the diet for a total of 12 weeks.
The diet will emphasize balanced intake of vegetables, fruits, whole grains, and protein foods, without specific macronutrient restrictions.
Dietitian counseling will be approximately matched in frequency and duration to the ketogenic diet arm.
Nutritional monitoring will include dietary logs and metabolic assessments without targeted induction of ketosis.
Participants will perform finger-stick glucose testing.
