Lobotomies are not banned by any single federal law in the United States, but asking whether they are illegal is the wrong way to frame it. Performing one today would violate state psychosurgery statutes in the states that have them, fail every modern informed consent standard, fall outside the medical standard of care in every state, and expose the physician to license revocation, malpractice liability, and potential criminal charges. The last widely documented lobotomy in the country was performed in 1967, and nothing about the legal terrain since then has left a viable path to performing another one.
No Federal Statute, and Why That Doesn’t Help
Congress never passed a law explicitly prohibiting lobotomies. During the procedure’s peak in the 1940s and 1950s, tens of thousands were performed with little regulatory scrutiny, and by the time public opinion turned sharply against the practice in the late 1960s and 1970s, the procedure was already vanishing on its own. Lawmakers saw less urgency in banning something that had largely stopped happening.
Instead of a single prohibition, the United States ended up with a patchwork of state laws, federal research oversight rules, and professional standards that collectively make the procedure untenable. The absence of a federal statute is not a loophole. It is simply the shape the restrictions took.
State Psychosurgery Statutes
Where federal law stayed silent, a number of states passed their own psychosurgery statutes, most of them in the 1970s and 1980s. The laws vary, but they share features that would make a lobotomy extraordinarily difficult, and in many cases outright illegal, to perform.
- Several states prohibit psychosurgery on anyone under 18, with no exceptions.
- Some states require that multiple physicians, often including board-certified psychiatrists or neurosurgeons not involved in the patient’s care, independently examine the patient and unanimously agree the procedure is warranted.
- A number of states require documentation that all other appropriate treatments have been tried and failed before psychosurgery can even be considered.
- At least one state makes it a misdemeanor to perform a lobotomy without the written consent of the patient’s next of kin or legal guardian, and a felony to perform one for the purpose of altering someone’s religious beliefs.
- Some statutes impose mandatory waiting periods between written consent and the procedure.
Not every state has a specific psychosurgery statute. But even in states without one, a lobotomy would collide with general medical practice laws, malpractice standards, and informed consent doctrine.
Informed Consent Is a Wall, Not a Hurdle
Modern informed consent law requires that a patient receive clear information about a procedure’s risks, benefits, and alternatives before agreeing to it. The patient must be competent, uncoerced, and given a genuine choice. For brain surgery, courts and medical boards apply these requirements strictly.
Honest disclosure of a lobotomy’s risks would include permanent personality changes, severe cognitive impairment, emotional flattening, seizures, and death. The benefits section would be thin, unsupported by modern clinical evidence. The alternatives section would be extensive, covering decades of psychiatric medications, cognitive behavioral therapy, and targeted neurosurgical techniques that did not exist when lobotomies were common. A competent patient receiving that disclosure would have no rational basis to consent, and a physician who softened any part of it to secure consent would fail the disclosure requirement.
Federal regulations reinforce this in the research context. Under the Common Rule, any investigator involving a human subject must obtain legally effective informed consent, provide the information a reasonable person would need, and give the subject adequate time to consider participation without coercion.1eCFR. 45 CFR 46.116 – General Requirements for Informed Consent Any attempt to reframe a lobotomy as “research” to escape clinical standards would trigger those federal protections and mandatory Institutional Review Board oversight.
What Happens to a Doctor Who Performs One
A physician who performed a lobotomy today would face consequences from several directions at once.
Medical License
State medical boards can investigate, discipline, suspend, or revoke a physician’s license for unprofessional conduct, which includes failing to meet the accepted standard of care. Every state’s Medical Practice Act defines the boundaries of acceptable practice, and performing an obsolete procedure with no evidence base and known devastating harms falls well outside them. The historical parallel is instructive: after Walter Freeman’s final lobotomy patient, Helen Mortensen, died from a brain hemorrhage in 1967, his surgical privileges were revoked. A modern physician would face swifter and harsher consequences.
Civil Malpractice
A malpractice claim requires showing that the physician deviated from the standard of care and that the deviation caused harm. A lobotomy fails the standard-of-care test so completely that proving the case would be straightforward. No credible expert witness would testify that the procedure meets contemporary medical standards, and damages from the known effects, including cognitive destruction, personality erasure, and possible death, would be enormous.
Criminal Charges
Surgery performed without valid consent is legally indistinguishable from battery: an unauthorized, harmful touching. Justice Cardozo wrote in an early landmark case that a surgeon who operates without the patient’s consent commits an assault. Prosecutors have historically been reluctant to charge physicians criminally when a procedure was at least intended to help the patient, but a lobotomy performed today would be hard to characterize as beneficial given that every major medical organization abandoned the procedure decades ago. If the patient suffered serious injury or died, charges ranging from battery to manslaughter would be realistic.
Patients Who Cannot Consent
The barriers grow steeper when the patient cannot consent for themselves. In most states, a guardian making healthcare decisions must use either substituted judgment (what the patient would have wanted) or a best-interests standard. For extraordinary procedures like psychosurgery, many states require prior court approval before a guardian can consent, often demanding clear and convincing evidence that the procedure serves the patient’s interests. A court authorizing a lobotomy in the modern era is, for practical purposes, inconceivable.
Insurance and Hospitals Close the Remaining Door
Even if the legal barriers were somehow cleared, the economics and institutions block the path. Medicare treats psychosurgery as investigational and does not cover it. The Centers for Medicare and Medicaid Services has specifically ruled that stereotactic cingulotomy, a far more targeted and refined psychosurgical procedure than a lobotomy, is not covered because it is considered investigational and does not meet the standard of being reasonable and necessary for treatment.2Centers for Medicare & Medicaid Services. NCD – Stereotactic Cingulotomy as a Means of Psychosurgery If Medicare will not cover a modern, targeted form of psychosurgery, it will not cover a lobotomy. Private insurers apply the same logic.
Without coverage, the entire cost of surgery, anesthesia, hospitalization, and any complications falls on the patient. No hospital’s legal department would approve the procedure in the first place, so a physician would also have to find a willing surgical facility. There isn’t one.
Modern Psychiatric Brain Surgery Is Not a Lobotomy
Brain surgery for psychiatric conditions has not disappeared entirely, and the distinction matters if you are trying to figure out what is actually prohibited. Several modern techniques bear no resemblance to the crude tissue destruction of a lobotomy and operate under intense regulatory scrutiny.
Deep brain stimulation (DBS) uses implanted electrodes that deliver controlled electrical pulses to specific brain regions. The FDA approved DBS for treatment-resistant obsessive-compulsive disorder in 2009 through a Humanitarian Device Exemption, which applies to devices intended for conditions affecting fewer than 8,000 patients per year.3U.S. Food and Drug Administration. Humanitarian Device Exemption – Reclaim DBS Therapy for OCD The approval specifies that DBS is only indicated after a patient has failed at least three different medications. DBS is also FDA-approved for Parkinson’s disease, essential tremor, and dystonia.4National Institute of Neurological Disorders and Stroke. Deep Brain Stimulation (DBS) for the Treatment of Parkinsons Disease and Other Movement Disorders
Stereotactic cingulotomy and anterior capsulotomy are ablative procedures that deliberately destroy a small, precisely targeted area of brain tissue. Unlike a lobotomy, which severed broad swaths of the frontal lobe’s connections, these procedures target millimeter-scale regions identified through advanced neuroimaging. They remain in use for severe, treatment-resistant OCD and depression. Any experimental psychiatric neurosurgery must be approved by an Institutional Review Board under federal regulations governing human subjects research, including the requirements of 45 CFR Part 46.5U.S. Department of Health and Human Services Office for Human Research Protections. Institutional Review Board (IRB) Written Procedures – Guidance for Institutions and IRBs
The short version: a lobotomy is not so much illegal as legally, medically, and ethically surrounded on all sides, with no viable path for any physician to perform one and survive the consequences. Modern psychiatric neurosurgery exists, but it is a different procedure done under different rules, and calling it a lobotomy would be inaccurate on every point that matters.
