Real-time fMRI neurofeedback (deCharms)

What it is

A participant lies in an MRI scanner while the activity of a chosen brain region (or a pattern across regions) is computed within seconds and shown back to them, typically as a moving bar or similar display, while they try mental strategies to move it up or down. In the 2005 study by Christopher…

Format

• rtfMRI-nf has no treatment manual for clinical use. The framework below has two strands: (A) the stages research studies typically follow, and (B) the parallel stages of the psychotherapist's work. Session numbers and scan settings are deliberately not given; they vary by study and belong to the…
• Study close and debrief. Goal: explain the study, possibly reveal group assignment (per protocol), communicate any incidental findings, and hand back to usual care.

Who practises it, and how they are trained or regulated

• Baseline assessment. Goal: measure symptoms and any cognitive or behavioural targets before training (e.g. MADRS in depression; CAPS in PTSD; autobiographical memory recall). Move on: baseline complete; randomisation to experimental or control condition, usually blinded.
• Training visits in the scanner. Goal: learn to change the feedback signal. Format: a small number of scanner visits (studies vary); within each, blocks of trying to regulate with feedback alternate with rest or control blocks (e.g. counting backward). Participants may get a suggested strategy and report what they actually used. Move on: per protocol, not by clinical judgement.
• Transfer test. Goal: check whether control persists without the display. Format: runs in which the participant regulates without seeing feedback.

Evidence status, as the guide reports it

• After: debrief, process the experience (including disappointment if no change or if assigned to a control condition), consolidate any useful strategies inside ordinary therapy, continue evidence-based treatment.

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Does it use a device, heat, cold, water or a physical procedure? Has a medical professional checked that it is safe for you?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• minimising symptoms to stay in the study.
• clients thinking about changing treatment to get into a study.
• anger or loss of trust if the client later learns they had sham feedback.
• the client seeing the trial as a last hope; acute risk, which comes first.
• relapse after study support ends; anger if unblinding shows sham feedback.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
