Every medical student should acquaint themselves with the discomfiting history of epilepsy surgery. Regardless of their eventual speciality, they will become better clinicians for it. As a cautionary tale of what happens when we lose sight of primum non nocere as our guiding principle in medicine, the sorry narrative is exemplary, putting well-intentioned doctors on the wrong side of history again and again.
Trepanning (drilling a hole in someone’s skull) has been conducted for millennia, with evidence of the oldest procedure dating back several thousand years. Archaeological finds of skulls with multiple holes in various states of repair indicate that at least some of our ancestors survived these treatments and came back for more. Opening a space to let the demons out of someone’s head makes sense, if you believe the pesky things have taken up residence and are running amok inside. At least this treatment was in the right anatomical ballpark, according to our current understanding of epilepsy as a neurological condition. Less than 130 years ago, surgery for epilepsy had “advanced” (or regressed) to the extent that the head was no longer the sole target of the surgeon’s scalpel.
They had branched out to recommend limb amputation. The rationale was straightforward: if someone’s arm keeps shaking, what more effective cure than to cut it off? Other surgical approaches to epilepsy in the 1890s included clitoridectomy and castration — both attempts to curb the immoral sexual appetites that were “well known” to cause epilepsy at the time. For the squeamish patients who wished to retain their sexual organs, alternative treatments included admonitions to avoid coffee, chocolate and amorous love songs. Late Victorian treatments for epilepsy were nothing if not eclectic.
Into the mid-20th century, people with epilepsy were once again the unwitting participants in a dark era of medical experimentation. In an enterprising spin-off, the radical surgical techniques developed in the Forties’ psychosurgery movement were trialled as treatments for epilepsy. All undergraduate psychology students (and fans of the film Memento) will be aware of Henry Molaison, better known by his initials. In October 1953, Mr Molaison underwent surgical excision of the right and left temporal lobes of his brain. In a short paper delivered six weeks after the surgery, his surgeon reported that the operation had resulted in no real changes, “with the exception of a very grave recent memory loss”; H.M. was unable to remember where his room was in the hospital, or how to find the toilet.
H.M.’s profoundly disabling amnesia persisted for the next 55 years, until his death in 2008. He became the most famous neuropsychological case study in the history of the profession. But he was not the first person to undergo this procedure and suffer this devastating outcome. Scores of others were discovered in a retrospective review, triggered by Mr Molaison’s case. His memory loss could have been anticipated and prevented if the outcome of this procedure had been fully evaluated in his predecessors. More shocking still is that a similar fate was allowed to befall a number of other patients after his amnesia was discovered. Ignorance is one thing, inertia something entirely different.
The lessons from this sobering history are clear. When doctors fundamentally misunderstand the cause of a condition and treat the symptoms instead, and fail to properly monitor outcomes, and modify their practice in response to known adverse outcomes, our patients suffer — often greatly and for the rest of their lives — if indeed they survive. These fundamental errors underpin the depressingly regular scandals that punctuate the history of medicine. (The stakes are particularly high if surgery is involved.)
