A bunch of Edmonton researchers is recruiting dozens of sufferers throughout the province to participate in a brand new medical trial geared toward serving to these affected by trigeminal neuralgia, traditionally dubbed the “suicide illness” due to the extreme influence it has on sufferers.
The time period dates again to a time earlier than efficient therapies have been obtainable, when an estimated quarter of sufferers died by suicide because of the severity of the ache.
“Trigeminal neuralgia is without doubt one of the most extreme pains identified to mankind,” mentioned Dr. Tejas Sankar, a neurosurgeon on the College of Alberta Hospital.
The situation causes excruciating, stabbing facial ache. Prior to now, remedy was nerve ache medicine.
Nonetheless, medical doctors say the unwanted side effects and effectiveness of medicines precipitated points for a lot of sufferers. One other invasive surgical procedure known as microvascular decompression may also be used. Gamma Knife radiation was used as a final resort.
Researchers are hoping to flip the change, utilizing the non-invasive surgical procedure as a primary resort.
“We deal with trigeminal neuralgia by giving a fairly excessive dose of radiation to the trigeminal nerve on the affected aspect, however the longer you wait earlier than you supply Gamma Knife, the much less doubtless it’s to result in long-term remission of the illness,” Dr. Sankar mentioned.
“What in case you might break that cycle a lot, a lot earlier… quickly after the analysis?”
Dr. Sankar mentioned his team’s research, utilizing MRI, exhibits that residing with the situation truly impacts the best way the mind works.

There are round 700 new circumstances of trigeminal neuralgia identified in Alberta yearly. The aim of the trial is to cease the modifications within the mind, earlier than they turn out to be everlasting.
“The longer you will have this facial ache situation, the extra lasting modifications happen within the mind each structurally and functionally,” Sankar mentioned.
Researchers wish to recruit 80 sufferers from throughout Alberta to participate within the trial on the Scott and Brown Households Gamma Knife Centre on the College of Alberta Hospital — the one facility of its variety within the province.
Half of the sufferers will obtain normal nerve ache drugs, whereas the opposite half will bear what researchers name “extremely‑early” Gamma Knife surgical procedure.
Researchers say the management group will obtain immediately’s normal remedy and might nonetheless go for Gamma Knife later, if wanted
Dr. Sankar’s staff will comply with sufferers for 5 years, evaluating their ache utilizing the worldwide normal Barrow Neurological Institute Facial Pain Scale.
“We all know from earlier than that sufferers who’re handled with Gamma Knife, even later within the illness, those who’re success tales are actual success tales,” he informed International Information. “They’re pain-free, their high quality of life is phenomenal, and so they’re off drugs.”
That features sufferers like Norm Sanche, who was identified with the situation 4 years in the past. Sanche informed International Information that earlier than he underwent Gamma Knife surgical procedure, he would endure generally as much as 3 times a day with ache.
“It’s like 110 volts to your head. It’s not enjoyable,” he mentioned. “It was a kind of issues that’s behind your thoughts. It’s form of scary since you by no means know when it’s going to go off.”
He underwent the process in April 2025 and mentioned after weaning off the medicine, he now lives a traditional, pain-free life.
“It’s a life-changer,” he mentioned. “Inside a month, I used to be on a golf course!”
The aim is for the Gamma Knife surgical procedure to break the nerve sufficient to interrupt the ache indicators being despatched between the face and the mind. By inducing delicate harm, surgeons intention to cease extreme “cross‑discuss” inside the nerve that permits ache indicators to over‑fireplace, whereas not damaging vital nerves that management issues like sensation within the face and chewing.
“It’s not as uncommon as you may suppose,” Dr. Sankar mentioned concerning the situation.
“One of many points is that, as a result of it’s not well-known, many individuals go fairly a while earlier than they get a analysis.”
Dr. Sankar mentioned more often than not folks find yourself going to their dentist as a result of the ache is within the jaw and the cheek, however that takes time.
“By that time, a number of months have handed and we’re form of preventing the clock as a result of that continual ache goes to turn out to be stamped into the mind,” he mentioned.
“We hope that one of many advantages of this trial isn’t just a greater approach to deal with trigeminal neuralgia by hitting it early with Gamma Knife but additionally growing consciousness of the illness so that folks can are available in shortly after they develop the signs.”
The Gamma Knife makes use of highly-focused beams of radiation to deal with mind situations. The one on the College of Alberta Hospital was introduced in 2017. It’s the just one west of Winnipeg in Canada and permits medical doctors to do highly-specialized procedures, and not using a scalpel.
“Entry to it has actually modified the sport,” Dr. Sankar mentioned. “Not only for the remedy of trigeminal neuralgia, but additionally the remedy of many different situations, you understand, mind tumours and mind cancers, different situations as effectively, blood vessel abnormalities.”
If early Gamma Knife surgical procedure prevents continual ache from turning into everlasting, Dr. Sankar hopes it might turn out to be first‑line remedy, sparing sufferers’ years of medicine unwanted side effects and remedy failure.
For sufferers like Sanche, the potential of earlier intervention is already clear.
“If I will help any individual else out, it’s a win-win,” he mentioned.
Recruitment for the research is ongoing, with sufferers being adopted for as much as 5 years to find out whether or not early Gamma Knife surgical procedure can forestall continual ache from turning into everlasting.
