Dieta Chetogenica e Neuromodulazione nella Depressione Resistenti al Trattamento (ALIGN)
Dieta Chetogenica Basso-Carboidrato Adiuvante per Migliorare la Neuromodulazione Guidata da Imaging nella Depressione Resistente al Trattamento
L'obiettivo di questo studio clinico è testare se la combinazione di una dieta chetogenica (KD) con una stimolazione intermitente theta burst accelerata e personalizzata (iTBS) produce una riduzione maggiore dei sintomi depressivi rispetto alla iTBS combinata con una dieta sana standard in adulti con depressione resistente al trattamento. Lo studio mira anche a determinare se i partecipanti possono seguire in modo fattibile una dieta chetogenica durante un ciclo di trattamento accelerato con iTBS e se la dieta produce cambiamenti misurabili nei livelli di chetoni.
Nello specifico, lo studio mira a determinare se l'intervento combinato:
- Riduce i sintomi depressivi
- Aumenta i livelli di chetoni circolanti
- È fattibile e tollerabile durante il trattamento accelerato con iTBS
I partecipanti inizieranno una dieta chetogenica (KD) o una dieta allineata alla Guida Alimentare Canadese (CFGD) con un periodo di introduzione dietetica di 3 settimane, dopo il quale seguiranno un ciclo di iTBS accelerata e personalizzata continuando la dieta assegnata. Prima e dopo il ciclo di trattamento con iTBS, i partecipanti completeranno valutazioni cliniche, forniranno campioni di sangue per test metabolici e sottoporranno a scansioni MRI per valutare la connettività cerebrale. I livelli di chetoni saranno misurati quotidianamente durante l'intervento dietetico di 15 settimane. Le differenze all'interno del gruppo e tra i gruppi saranno confrontate per caratterizzare i cambiamenti negli esiti clinici, nel metabolismo e nel funzionamento cerebrale.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: 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.

|
|
Comparatore attivo: 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.
