“Best buddy,” she whispers.
Noreen Smith is among the three per cent of the Canadian population who suffer from a nervous system disorder called essential tremor. It causes uncontrollable shaking, most often in a person’s hands.
“This particular person wasn’t terribly helpful because he said: ‘Do you happen to know Katharine Hepburn? I’m going to give you some medication, and you can go home and get used to the idea that eventually you’re going to end up looking like Katharine Hepburn.’ I was devastated,” says Smith.
Medication helped for the first few years.
When Smith tried to do that, much of the water spilled into the kitchen sink. And when she attempted to put the glass to her mouth for a sip, it was virtually impossible to accomplish.
Essential tremor won’t shorten Smith’s life, but it was definitely affecting her quality of life.
“We’re invited out to dinner and I won’t go because I’m embarrassed dropping food. Even at food courts, sometimes we’d have a cup of coffee and Brian would have to hold the cup and feed me. It’s so embarrassing.”
All the more reason the Smiths were “absolutely elated” when they heard Noreen was considered a solid candidate for a medical procedure called “MRI-guided focussed ultrasound” technology, a treatment approved last month by Health Canada.
“This is a game changer,” says Sunnybrook neurosurgeon Dr. Nir Lipsman. “It really changes the way we think about surgical treatments for tremor. No scalpel needed. No drill needed.”
Instead, the treatment uses a more non-invasive approach. The technology allows doctors to focus ultrasound waves guided by an MRI through a patient’s skull to reach an area located deep in the brain called the thalamus. The sound waves target and destroy the cells that cause the tremor.
“What we’re effectively doing with this procedure, in a non-invasive way, is killing those neurons and destroying those neurons with high frequency focussed ultrasound,” says Lipsman.
That’s compared to less than one per cent improvement in those who received a so-called “sham procedure” or placebo.
The technology “will open up a new era that will revolutionize the way brain diseases will be treated, eventually benefitting millions of patients,” says Dr. Kullervo Hynynen, director of physical sciences at Sunnybrook Research Institute. He also helped develop the technology.
Lying inside the MRI machine last week at Sunnybrook, Smith patiently endured the four-hour procedure.
Like all other patients before her — and so far there have been about 40 at Sunnybrook — she remained awake and was closely monitored by a team of neurosurgeons and MRI technicians in a nearby room.
When it was over, when she walked out of the MRI room. Doctors removed the cumbersome helmet, she sat down and performed a few tests for Lipsman.
“Couldn’t do that before,” she said.
She was handed a glass of water. She drank it, without a drop falling. She beamed with satisfaction.
“This is amazing.”
Finally, she was asked to write her name, a task that has been impossible for decades.
Her penmanship was flawless.
“Just being able to to hold my hand like that — it’s miraculous.”
For good measure, she rose from her wheelchair and performed an Irish jig.
Doctors hope to apply the technology in the treatment of other diseases like Parkinson’s and epilepsy.
“I will be able to sign my husband’s card for our 50th wedding anniversary,” she told reporters, “which is coming up at the end of the year.”
