Dieta Cetogénica e Neuromodulação na Depressão Resistente ao Tratamento (ALIGN)
Dieta Cetogénica Baixa em Carboidratos como Adjuvante para Potenciar a Neuromodulação Guiada por Imagiologia na Depressão Resistente ao Tratamento
O objetivo deste ensaio clínico é testar se a combinação de uma dieta cetogénica (KD) com estimulação theta burst intermitente acelerada e personalizada (iTBS) produz reduções maiores nos sintomas depressivos do que a iTBS combinada com uma dieta saudável padrão em adultos com depressão resistente ao tratamento. O ensaio também visa determinar se os participantes conseguem seguir de forma viável uma dieta cetogénica durante um curso de tratamento acelerado com iTBS e se a dieta produz alterações mensuráveis nos níveis de cetonas.
Especificamente, o estudo visa determinar se a intervenção combinada:
- Reduz os sintomas depressivos
- Aumenta os níveis de cetonas em circulação
- É viável e tolerável durante o tratamento acelerado com iTBS
Os participantes iniciarão uma KD ou uma dieta alinhada com o Guia Alimentar Canadiano (CFGD) com um período de introdução dietética de 3 semanas, após o qual realizarão um curso de iTBS acelerada e personalizada enquanto continuam a dieta atribuída. Antes e após o curso de tratamento com iTBS, os participantes completarão avaliações clínicas, fornecerão amostras de sangue para testes metabólicos e realizarão ressonâncias magnéticas para avaliar a conectividade cerebral. Os níveis de cetonas serão medidos diariamente ao longo da intervenção dietética de 15 semanas. As diferenças intra-grupo e inter-grupos serão comparadas para caracterizar as alterações nos resultados clínicos, no metabolismo e no funcionamento cerebral.

Experimental: 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.

Comparador Ativo: 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.
