Stereotactic psychosurgery (cingulotomy, capsulotomy, gamma knife)

What it is

This is not a psychotherapy. It is irreversible brain surgery decided and delivered by a multidisciplinary specialist team (stereotactic and functional neurosurgeons, psychiatrists, neurologists, neuropsychologists), for a very small number of people with severe, chronic, disabling…

Format

• Treatment-refractory phase (before any referral). Goal: make sure every reasonable, less invasive, evidence-based option has been tried at adequate dose and duration: medicines, CBT (ERP for OCD) and ECT where relevant. One gamma-capsulotomy study required at least 20 sessions of CBT with ERP…
• Surgery and early recovery. Delivered by the neurosurgical team; short-term effects such as incontinence, sleep problems, fatigue and disorientation usually settle within weeks after thermal capsulotomy. Psychotherapist: usually a pause in sessions; keep contact and the crisis plan active.

Who practises it, and how they are trained or regulated

• Consent, capacity and legal certification. Goal: free, informed, sustained consent from a person with capacity, checked repeatedly; then the statutory or tribunal process for the jurisdiction (see 4A.2). Surgery cannot proceed until certificates or approval are in place.
• Evidence status: the consensus guideline describes ablative procedures as "established" in some countries for depression and OCD with level II (not level I, randomised) evidence, and sets as a standard for an approved therapy at least two blinded randomised trials from different groups. Deep brain stimulation (DBS), the reversible alternative, is described as still investigational for every psychiatric indication.…

Evidence status, as the guide reports it

• Treatment-refractory phase (before any referral). Goal: make sure every reasonable, less invasive, evidence-based option has been tried at adequate dose and duration: medicines, CBT (ERP for OCD) and ECT where relevant. One gamma-capsulotomy study required at least 20 sessions of CBT with ERP…

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?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• How do you and the practitioner understand what is happening, in spiritual or cultural terms? Is that a source of comfort, worry, or both?
• 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

• dropping out of follow-up years later.
• all-or-nothing goals; no plan for non-response.
• stopping medicines unilaterally after improvement; missing follow-up.
• shame, a sense of being "not myself", or a family describing someone new.
• "this is my last chance" statements; withdrawal after refusal; hopelessness at months 3-12.

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.
