The technology

What are TPS (Transcranial Pulse Stimulation)
and the Neurolith®?

TPS (Transcranial Pulse Stimulation) is a non-invasive neuromodulation technique using mechanical waves — ultra-short acoustic pulses (3 µs) at low energy (0.1–0.25 mJ/mm²) — to selectively stimulate target brain structures (art. R4321-7 of the French Public Health Code).

Guided by the patient's MRI, the Neurolith® by Storz Medical delivers these pulses with millimetric precision, reaching areas inaccessible to other ultrasound stimulation techniques.

Unlike rTMS or tDCS, this ultrasound neuromodulation technique allows three-dimensional stimulation at depth, including the hippocampus, the medial prefrontal cortex and the basal ganglia — structures directly involved in Alzheimer's disease, Parkinson's disease and treatment-resistant depression.

A session lasts about 45 minutes; the patient is seated and feels no pain. No anaesthesia and no drug preparation are required.

Mechanotransduction

Acoustic shockwaves exert mechanical forces on cell membranes, activating intracellular signalling pathways and stimulating the production of growth factors.

Angiogenesis & revascularisation

Stimulation of VEGF production, promoting the formation of new vessels and improved local cerebral perfusion in the targeted areas.

Nitric oxide (NO)

Production of endogenous NO inducing local vasodilation and an anti-inflammatory action, improving the oxygenation of the target brain tissues.

Neurotrophins (BDNF, NGF, FGF-2)

Release of neurotrophic factors promoting neuronal survival, neurite growth and the repair of damaged synaptic circuits.

Neurogenesis

Stimulation of the production of new neurons in the hippocampus and promotion of their integration into existing circuits — a region critical for memory.

Synaptic plasticity (LTP)

Induction of long-term potentiation mechanisms, strengthening synaptic connections and improving the efficiency of the neural networks involved in cognitive functions.

Functional indications

Transcranial Pulse Stimulation: indications — Alzheimer's disease (CE marking) and other uses

The centre offers neuromodulation programmes using Transcranial Pulse Stimulation (TPS) after clinical assessment and verification that there is no contraindication. A favourable opinion from the neurologist or treating physician is systematically required before any protocol.

Alzheimer's disease — CE-marked indication. The Neurolith® holds a CE marking for the stimulation of the central nervous system in patients with Alzheimer's disease. The centre applies the protocol derived from the published studies, with a standardised assessment at entry and at discharge.
Other indications — off-label framework. For the other situations (Parkinson's disease, treatment-resistant depression, essential tremor, ADHD, post-stroke…), TPS is used outside the CE indication (off-label): the technique is the subject of ongoing research, its effects are under evaluation, and it is not a validated or curative treatment. Every off-label programme is therefore conducted with the rigour of a research protocol: prior opinion from the neurologist or the treating physician, standardised assessments before and after, traceability of results, monitoring of adverse events, and a report sent to your physician.

The practitioner

Expertise at the crossroads
of physiotherapy and neuroscience

Charles du Teil — Physiotherapist and Osteopath — Centre TPS Paris 17
Charles du Teil
Physiotherapist – Osteopath D.O.

A physiotherapist and osteopath for 18 years, based at 7 rue Anatole de la Forge, Paris 17th, I devote a growing part of my practice to the neuromodulation of cognitive and motor impairments of neurological origin.

Trained in the TPS technique in Düsseldorf with Prof. Sprick, Dr Günes and the Storz Medical teams, pioneers of this approach in Germany, I chose to create the first TPS neuromodulation centre in France in order to offer my patients with Alzheimer's disease, Parkinson's disease or treatment-resistant depression a serious option, based on the published data, with no serious adverse event reported in the studies.

Düsseldorf training Prof. Sprick Dr Günes Storz Medical

This project grew out of a conviction: patients with cognitive or motor impairments of neurological origin deserve access to the most advanced rehabilitation techniques as soon as those techniques show a satisfactory safety profile and measurable results.

The rehabilitation programme offered is structured, reproducible and documented. Every patient receives a standardised assessment before and after rehabilitation. A full report is sent to the referring physician at the end of the programme.

I work in close collaboration with the neurologists and psychiatrists who follow my patients, and I undertake not to treat any patient whose profile is not compatible with TPS.

"To give every patient the best possible chance of preserving and restoring their functional capacities, through scientifically evaluated rehabilitation techniques, within an ethical and rigorous framework."

Frequently asked questions

Frequently Asked Questions — TPS & Neuromodulation

What is Transcranial Pulse Stimulation (TPS)?
TPS is a non-invasive neuromodulation technique that uses mechanical waves (ultra-short acoustic pulses of 3 microseconds) guided by MRI to stimulate target brain areas. The device used is the Neurolith® by Storz Medical, a CE-certified Class IIb medical device. A favourable opinion from the neurologist or treating physician is systematically required before any protocol.
What does “outside the CE indication (off-label)” mean?
The CE marking of the Neurolith® covers Alzheimer's disease. For the other situations (Parkinson's disease, treatment-resistant depression, essential tremor, ADHD…), TPS is used “off-label”: the technique is the subject of ongoing research and its effects are under evaluation — it is not a validated or curative treatment. This does not mean improvised practice: every off-label programme requires the prior opinion of your neurologist or treating physician, relies on standardised assessments before and after, and is subject to traceability of results and monitoring of adverse events, with a report sent to your physician.
Which conditions are treated?
Centre TPS Paris 17 treats patients presenting with:
  • Indication covered by the CE marking: Alzheimer's disease (and early MCI, by extension)
  • Indications outside the CE marking — off-label use, for experimental purposes (effects under evaluation, preliminary data): Parkinson's disease, treatment-resistant depression, Lewy body dementia, essential tremor, MSA, adult ADHD, post-stroke, neurological post-COVID
Is TPS painful?
No, TPS is painless and non-invasive. The patient feels light tapping on the skull. In the published clinical studies (Matt et al., JAMA Network Open 2025), no serious adverse event was reported. About one third of patients report mild, transient headaches, which resolve spontaneously within 24 hours.
How much does a TPS protocol cost? Is it reimbursed?
The full initial protocol (6 sessions, including the entry and discharge assessments) is priced at 2 000 €. Maintenance boost sessions cost 300 €. TPS is not reimbursed by the French national health insurance (Assurance Maladie). Payment in instalments is possible on request. Some complementary health insurers cover part of the cost — check with yours.
How does a TPS protocol work?
Our protocols are designed to follow the scientific literature as closely as possible. The initial programme comprises 6 sessions over 2 weeks (3 sessions per week). For Parkinson's disease, protocols may extend to 10 sessions with the patient's agreement, in line with the published data. Each session lasts about 45 minutes. The first session includes standardised assessments (MoCA, Stroop, BDI-II for cognitive impairment; MDS-UPDRS III for motor disorders). The last session includes the discharge assessment, and a report is sent to the referring physician. Maintenance sessions every 4 to 6 weeks may be recommended.
Is a prescription required for TPS?
A prescription is not required, as TPS is not reimbursed by the French national health insurance (Assurance Maladie). However, a favourable opinion from the neurologist or treating physician is systematically required before starting any protocol. If you do not have a referring physician, we can point you in the right direction.
What results can be expected from TPS?
Results vary according to the condition, the stage of the disease and the patient. The clinical studies published in international peer-reviewed journals report:

Alzheimer's disease:
  • Significant improvement in the CERAD score: +3.91 points on average in patients ≤70 years at 3 months, versus −1.83 points under sham stimulation (double-blind randomised trial, 60 patients, Matt et al., JAMA Network Open, 2025)
  • Improvement in memory, verbal communication and spatial orientation (Beisteiner et al., Advanced Science, 2020)
  • Signs of reduced cortical atrophy in critical brain regions (Popescu et al., Alzheimer's & Dementia, 2021)
  • Effects maintained for at least 3 months, and up to 12 months with maintenance sessions (Cont et al., Frontiers in Neurology, 2022)
Parkinson's disease:
  • Significant improvement in the UPDRS-III motor score: from 16.70 to 12.95 on average (p < 0.001), i.e. a large effect size (Cohen's d = 1.38) in 20 patients, 10 sessions (Cont et al., Frontiers in Neurology, 2024)
  • Reduction of resting tremor after a single session (Manganotti et al., Brain Research, 2025)
Depression:
  • Significant reduction in the BDI-II score (Beck Depression Inventory) in Alzheimer's patients with comorbid depression, maintained at 3 months (Matt et al., Alzheimer's & Dementia, 2022)
TPS is an add-on treatment: it does not cure the disease but may improve functional capacities and quality of life. A neuropsychological assessment before and after makes it possible to measure the results objectively for each patient.
Are there contraindications to TPS?
Yes, the main contraindications are:
  • Active malignant brain tumour
  • Metallic intracranial implant (clips, DBS electrodes…)
  • Pacemaker or implantable defibrillator
  • Uncontrolled epilepsy (less than 3 months)
  • Pregnancy (current or suspected)
  • Active thrombosis
  • Corticosteroid therapy within the previous 6 weeks
  • Haemophilia or coagulation disorders
The presence of a contraindication does not necessarily mean that the protocol is impossible — it calls for a further evaluation. These criteria are checked in the pre-session questionnaire and at the entry assessment.
What is the difference between TPS and rTMS?
TPS (Transcranial Pulse Stimulation) uses mechanical waves (acoustic pulses) to stimulate the brain, whereas rTMS (repetitive Transcranial Magnetic Stimulation) uses magnetic fields. Main differences:
  • TPS penetrates more deeply into brain tissue (up to 8 cm vs 2-3 cm for rTMS)
  • TPS is guided by MRI in real time, allowing precise targeting of the areas to be stimulated
  • TPS uses mechanical waves (no electromagnetic field)
  • The TPS protocol is shorter (6 sessions vs 20-30 for rTMS)
Can I continue my medication during TPS?
Yes, in the vast majority of cases. TPS is compatible with common drug treatments (cholinesterase inhibitors, memantine, L-DOPA, antidepressants). There is no need to interrupt your treatment. Coagulation disorders and anticoagulant treatment at therapeutic doses must be reported and assessed on a case-by-case basis. Your prescribing physician and the physiotherapist assess compatibility together.
How do I book an appointment at Centre TPS Paris 17?
You can book an appointment: The centre is located at 7 rue Anatole de la Forge, 75017 Paris (Metro Argentine L1 — 3 min walk). Please remember to bring a recent brain MRI.
Is TPS effective for Alzheimer's disease?
The clinical studies show encouraging results. The randomised controlled trial by Matt et al. (JAMA Network Open, 2025) in 60 patients demonstrated a significant improvement in the CERAD score (+3.91 points in patients ≤70 years at 3 months, versus −1.83 under sham). The pioneering study by Beisteiner et al. (2020) in Advanced Science had already reported improvements in memory, verbal communication and spatial orientation after 6 sessions. Popescu et al. (Alzheimer's & Dementia, 2021) observed signs of reduced cortical atrophy. TPS does not cure the disease but may slow cognitive decline and improve day-to-day independence.
