I have long-term, treatment-resistant depression, and adult add. my add meds always stop working. any new add meds i could ask about?

Many options: Not long ago, one medication for ad/hd (stimulants) was used. Today, multiple completely different medicines (with unique mechanisms of action). Behavioral therapies and use of assistive technologies on the web and in smatphones can also make a big difference. Some evidence shows neuro-training and biofeedback approaches to be promising. Talk with your primary doc about an ad/hd specialist.
