SAINT® Therapy for Memory Problems in Older Adults With Treatment-Resistant Depression

The goal of this clinical trial is to learn whether Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT®), a type of transcranial magnetic stimulation (TMS), is safe and may improve memory and thinking in adults aged 65 or older with treatment-resistant depression and memory concerns. Researchers will also study whether SAINT® improves depression symptoms. The main questions it aims to answer are: * Does SAINT® improve memory and thinking five days after treatment? * Does SAINT® improve depression symptoms and overall well-being? * Do changes in memory, mood, or daily activities last for up to one year? * What side effects or safety concerns occur during and after treatment? All participants will receive SAINT® treatment. There is no placebo group. Participants will: * Complete memory, mood, and health assessments and have an MRI scan * Receive 10 TMS sessions each day for 5 days in a row * Return for follow-up visits for up to 12 months Researchers will track changes in memory, mood, daily activities, and side effects.
