BERLIN — Wanting extra like a barber than a health care provider, orthopedic surgeon Musa Citak squirted gel on on his affected person’s head and massaged the gooey substance into his scalp as if it had been shampoo. He then pulled out a handheld gadget and commenced sliding it throughout the facet of the aged man’s head.
“That is shockwave remedy,” Citak defined. As he moved the gadget, it made fast clicking sounds, every click on a high-frequency sound wave supposed to stimulate mind areas and, based on Citak, assist regenerate cells and halt the fast deterioration of the affected person’s mind.
Manfred Sköries, 80, has been dwelling with a blended prognosis of Alzheimer’s illness, Parkinson’s, and Lewy physique dementia since 2012, leaving him with important reminiscence loss, issue strolling, and slurred speech. After making an attempt a number of drug therapies and exhibiting no important enhancements, his household reached out to Citak’s clinic in Berlin, TPS Nord. The clinic’s web site promised “a causal remedy of signs” and “everlasting stopping” of Alzheimer’s illness.

With no remedy for Alzheimer’s, Sköries is considered one of tons of of sufferers who’ve come to Citak previously 12 months, determined for assist. The remedy, often called “transcranial pulse stimulation,” is basically unproven, but it surely has exploded far past German borders: In simply two years, round 85 clinics throughout Europe, Asia, the Center East, and the US have begun providing the remedy. Storz Medical, the Swiss-based producer of the gadget, mentioned at the least 1,500 sufferers in 23 nations have undergone a complete of about 10,000 remedy classes.
Twenty minutes and 6,000 pulses later, Sköries’ remedy was full. He appeared exhausted, however his household was thrilled. This was his ninth session and his household mentioned they’ve witnessed beautiful outcomes: Earlier than the remedy, Sköries was silent, unresponsive, and moved largely in a wheelchair; now he generally walks up and down stairs, bursts into conversations, and has regained a humorousness, they mentioned.

“We’re actually satisfied by the outcomes,” mentioned Maik Sköries, Manfred’s grandchild. “For us, that is the true deal.”
But anecdotes aren’t sound proof, and the science behind TPS is way from convincing, specialists say. Research of its efficacy are restricted and their strategies questionable, and there’s no actual understanding of how the know-how acts on the mind past speculative theories, specialists say. The remedy can be largely unregulated and costly, costing 1000’s of {dollars} that sufferers need to pay out of pocket. Critics accuse clinicians adopting the know-how and Storz Medical of profiting from households determined for assist.
“They’re elevating false hopes,” mentioned Robert Howard, professor of outdated age psychiatry at College Faculty London. “I hesitate to make use of the phrase quackery, however this isn’t scientific evidence-based drugs.”
Main Alzheimer’s organizations are additionally skeptical. “It’s regarding that claims are being made which describe TPS as ‘clinically confirmed’ to scale back the signs of dementia. To our information there is no such thing as a convincing proof to justify this,” mentioned Tim Beanland, head of information administration on the Alzheimer’s Society, a number one dementia charity primarily based in the UK.
TPS has its roots in “shockwave remedy”— repetitive acoustic pulses that generate stress waves — which was first used at excessive power ranges in drugs to pulverize kidney stones. With the appearance of lower-energy pulses, the know-how rapidly grew to become an all-purpose remedy, with makes use of starting from joint and again ache to erectile dysfunction. Extra not too long ago, Storz Medical devised a brand new shockwave gadget, which it calls Neurolith, that may goal one other organ: the mind.
Lots of the mind areas most affected by Alzheimer’s and Parkinson’s lie deep inside, however Storz says its shockwaves can penetrate as much as 2 to three inches beneath the cranium.
The important thing analysis cited by proponents of the remedy was led by Roland Beisteiner, an affiliate professor of neurology on the Medical College of Vienna, who carried out a collection of experiments that had been partly funded by Storz Medical and generally in collaboration with firm researchers.
In a pilot examine with no management group, Beisteiner reported in 2019 that after two to 4 weeks of TPS remedy, 35 Alzheimer’s illness sufferers confirmed important enhancements on a take a look at of memory and speaking talents. The consequences lasted at the least three months. A follow-up examine analyzing 17 of those sufferers’ mind scans confirmed that these enhancements had been related to a reduction in degeneration in mind networks implicated in Alzheimer’s illness. And in a paper revealed this previous February, the staff discovered that these same patients’ depression scores dipped after two to 4 weeks of TPS remedy.
However critics say the science remains to be untimely. Solely a handful of research have appeared on the results of transcranial pulse stimulation particularly on Alzheimer’s sufferers. None was a double-blind randomized managed trial — the gold-standard scientific methodology used to judge whether or not a remedy is efficient — nor did any have a look at its long-term results past three months.
Usually, such research would management for the placebo impact by, for instance, probing some sufferers with an actual gadget and one other group with a faux or “sham” gadget that mimics the sound and really feel of TPS. However the research to this point haven’t executed this in medical trials, mentioned Peter Whitehouse, professor of neurology on the College of Toronto.
The research additionally reuse a small group of Alzheimer’s sufferers that fluctuate wildly within the severity and nature of their situations, making it laborious to discern the true advantages of the remedy. Many sufferers within the 2019 examine, for example, had comorbidities like melancholy, panic dysfunction, coronary coronary heart illness, and suspected epilepsy.
“This know-how might change into very efficient. It might change into terrific,” mentioned Michael Gusmano, a professor of well being coverage at Lehigh College in Pennsylvania and creator of a e-book on medical units. “However at this stage, I don’t suppose we have now sufficient proof.”
“This know-how might change into very efficient. It might change into terrific. However at this stage, I don’t suppose we have now sufficient proof.”

Beisteiner and Storz Medical reject these criticisms, saying the proof is already sufficiently sturdy to warrant promoting the product extensively, particularly since Alzheimer’s sufferers haven’t any viable options. “The protection is confirmed and the medical effectiveness of the remedy is confirmed,” mentioned Thi-Lan Freedman, a administration trainee for Storz Medical.
Whereas she acknowledged that the research are imperfect, she mentioned that larger-scale medical trials utilizing extra rigorous strategies are ongoing and that the corporate will get common suggestions from clinicians that sufferers are exhibiting nice advantages. Freedman contended that getting “CE marking” in 2018 — a designation that permits medical units to be commercially offered in Europe — additionally testifies to the know-how’s medical efficacy.
“CE marking,” nevertheless, hardly constitutes a assure of medical efficacy, specialists say. The analysis course of is targeted on security and is carried out by non-public organizations accredited by an EU nation often called “notified our bodies.” They’ve notoriously low requirements for evaluating whether or not a remedy works for medical units, mentioned Tom Joyce, professor of orthopedic engineering at Newcastle College within the U.Ok. The analysis course of can be largely invisible to the general public, which means producers can’t be held accountable.
“We all know little or no concerning the CE mark,” mentioned Joyce. “The product will get it and, on what proof it received the CE mark in Europe, we all know nearly nothing.”
The dearth of stringent rules on medical units has led to main scandals in Europe. In a single case, TÜV Rheinland, the notified physique in Germany that granted CE marking to Neurolith, certified faulty breast implants stuffed with low cost, industrial-grade silicone that affected 400,000 girls, lots of whom suffered from infections and needed to have the implants eliminated.
TÜV Rheinland didn’t reply to questions on its analysis course of with Neurolith, citing consumer confidentiality.
“That is simply not a remedy that’s received a demonstrated medical efficacy base,” mentioned College Faculty London’s Howard, who’s satisfied that the alleged advantages of the remedy might merely be attributable to a placebo impact, which tends to be notably sturdy in Alzheimer’s sufferers determined for an efficient remedy.
Some clinicians who provide TPS readily admit that the science is missing. Mohamed Abdelghani, a advisor psychiatrist who presents the remedy at his non-public clinic, Dyad Medical, in London, mentioned the proof is “restricted.” However he and others justify providing the remedy largely as a result of CE marking confirms its security and the intervention lasts solely about two weeks, so sufferers can cease instantly in the event that they don’t see any advantages.
Of the round 10,000 classes carried out since Neurolith’s launch in 2018, there have been no experiences of great opposed results, based on Storz Medical. Beisteiner’s research additionally confirmed that solely a small proportion of sufferers skilled minor uncomfortable side effects like complications and temper decreases, and that rat brains stimulated at power ranges as much as 150 occasions that utilized in people confirmed no mind harm.
“The great factor is that both it really works or it doesn’t — you don’t harm [the brain]. There is no such thing as a actual drawback to the affected person,” mentioned Citak, of TPS Nord.
Howard, nevertheless, mentioned that research on sufferers lasting solely three months aren’t lengthy sufficient to make sure the remedy is protected for sufferers. There could also be a cumulative impact of TPS that harms the mind, added Whitehouse.
Even when the dangers of bodily hurt change into negligible, specialists say sufferers face other forms of hurt. The complete remedy typically prices between $3,000 and $6,000, relying on the clinic, and there’s presently no medical health insurance — public or non-public — that covers these prices, mentioned Manfred Schulz, director of enterprise improvement and neurology at Storz Medical. Storz Medical is negotiating with German insurance coverage corporations to try to persuade them to cowl the remedy. Sufferers pay tons of of {dollars} extra for extra “booster” classes if they’re deemed needed.
For a illness that’s already extremely burdensome, it will be wiser to make use of that cash to enhance the affected person’s high quality of life, mentioned Thomas Fischer, professor of aged care nursing on the Protestant College of Dresden, in Germany. That will imply reworking a affected person’s dwelling to make it simpler to stay in, happening a vacation, or hiring a nurse to deal with them.
Beisteiner responded {that a} “massive a part of sufferers ask for remedy repeats, indicating that they choose TPS nearly as good worth for his or her cash.”
The Neurolith is basically unregulated within the nations the place it’s used. The gadget is offered to personal clinics with an accompanying instruction guide, however clinicians don’t get coaching and generally go off-script.
That is the case with Citak, who makes use of TPS as an “off-label” remedy for sufferers with Parkinson’s illness and melancholy, regardless of there being no revealed proof for its use in these situations. He mentioned he stimulates mind areas that he has personally mapped out and retains confidential to stop competitors from different clinicians. “We don’t inform,” he mentioned. “Secret.”
Till this week, his clinic’s website stated that TPS has been authorized by the Federal Institute for Medicine and Medical Units, Germany’s regulatory physique for well being merchandise, and that non-public insurers had been subsequently required to cowl the prices, when actually it merely was granted the CE mark by TUV Rheinland, a non-public entity.
After the misstatements had been identified by STAT, Citak’s clinic agreed that the knowledge was incorrect they usually had been taken down on Monday. “Musa is a health care provider and never an skilled in licensing — he doesn’t need to be,” mentioned Katja Schmidt, challenge supervisor on the clinic.
The operator of a Florida clinic providing TPS makes use of a equally broad strategy to utilizing the know-how. Boris Kawliche, a psychiatrist who has been providing TPS at Brandon TMS and Psychiatry since November, mentioned he’s the one clinician within the U.S. to personal a Neurolith and has handled about 10 sufferers with varied situations, together with Alzheimer’s, traumatic mind damage, aphasia, melancholy, and Parkinson’s. All sufferers had been handled in precisely the identical manner, regardless of important variations within the underlying causes of their diseases and their signs.
His outcomes, which haven’t been revealed or peer-reviewed, have been blended, he mentioned: Some sufferers present nearly no signal of change. Others, like a Parkinson’s affected person in his mid-70s, confirmed exceptional, although short-term, enhancements; earlier than remedy he was withdrawn and unable to stroll. After a few classes, he was greeting individuals and strolling lengthy distances, the physician claimed.
“Sadly, he received dwelling and the results lasted solely two weeks,” Kawliche advised STAT.
Neurolith just isn’t authorized by the U.S. Meals and Drug Administration. Schulz mentioned Storz Medical is working with its New York-based distributor, Soterix Medical, to use to the FDA to make use of the gadget for investigational functions within the U.S., and to acquire approval of an institutional overview board (IRB).
Nonetheless, Kawliche mentioned Soterix offered him the gadget for round $100,000, with Storz Medical’s approval, and advised him that the FDA would permit him to deal with sufferers if he carried out a examine that adopted Beisteiner’s strategies and labored towards acquiring approval of the examine from an IRB. He didn’t have the assets to hold out this examine, Kawliche mentioned, however he started treating sufferers after consulting a lawyer. (The lawyer denied telling Kawliche he might deal with sufferers with TPS.)
Examine sponsors sometimes need to get IRB approval earlier than finding out medical units on sufferers to make sure that experiments are carried out ethically and that sufferers are correctly knowledgeable of the potential dangers and consent to take part in a examine. Continuing with out such approval “just isn’t permitted,” mentioned Diana Zuckerman, president of the Nationwide Heart for Well being Analysis.
An FDA spokesperson mentioned the company sometimes doesn’t touch upon the usage of a tool that has not been authorized or cleared.
Storz Medical initially advised STAT it shipped one Neurolith to the U.S., to Soterix, in order that it could possibly be used for demonstration functions. Schulz later acknowledged that Kawliche might have bought this gadget when STAT identified that Kawliche had posted a number of photographs of himself on LinkedIn posing with a Neurolith at his Florida clinic over the previous 12 months.
Schulz mentioned the corporate has many customers of its units internationally so “it’s unattainable to know what everyone seems to be doing. However he [Kawliche] appears to be a particular case.”
Storz Medical and Soterix declare they weren’t conscious that Kawliche was treating sufferers and that he shouldn’t have executed so. But each had been in common contact with Kawliche and a number of Storz Medical staff reacted to and commented on social media posts of the Florida clinician describing his expertise utilizing the gadget on sufferers.
Not all clinics have been so unfastened with how they use TPS. Abdelghani, the London psychiatrist, mentioned his clinic has had 20 inquiries previously 12 months, however just one affected person has began remedy with the know-how after screening. Individuals with extreme Alzheimer’s aren’t eligible to make sure they’ve the capability to consent. The consent type consists of data that highlights the dearth of medical proof behind the remedy and the chance that any advantages skilled could also be attributable to a placebo impact.
Not being cautious like this dangers backfiring, he mentioned. “I believe this ought to be executed not solely to guard sufferers, however to guard the know-how.”
However others say warning and transparency aren’t sufficient. Below the present system, medical units in Europe can enter the market with little to no scrutiny of their medical efficacy. Joyce, of Newcastle College, mentioned the method must be extra clear in order that sufferers and policymakers can consider the proof themselves. A framework for this sort of transparency already exists, but it surely received’t make posting data within the database obligatory till late 2023.
The European Union’s lax medical-device rules are underpinned by an ethical obligation to supply severely ailing sufferers with new applied sciences as quickly as doable, particularly if there are not any options. Nonetheless, a slower, extra deliberative strategy may very well be extra conducive to serving to these sufferers in the long term, mentioned Lehigh’s Gusmano.
“New isn’t all the time higher,” he mentioned. “This isn’t about making an attempt to inappropriately gradual the usage of know-how. It’s about making an attempt to most appropriately choose and use these applied sciences which can be truly good worth.”
