Science & Evidence

Research and Publications

CIREN's scientific work integrates basic research with clinical care, advancing neurological restoration through evidence-based medicine.

Our Scientific Mission

Bridging Basic Research and Clinical Care

Since its founding in 1989, CIREN has combined a basic research program with a clinical care area, creating a model where scientific investigation directly informs patient treatment. This integration allows findings from the laboratory to be translated into rehabilitation protocols and therapeutic approaches.

The institution's research is grounded in the principle of neuroplasticity — the nervous system's capacity to reorganize and adapt — which underpins the Neuro-Restorative, Multifactorial, Intensive, and Personalized treatment technology developed at CIREN.

Clinical Impact Since 1989

Three Decades of Translating Research into Care

Since its founding on February 26, 1989, CIREN's research-driven treatment protocols have reached patients worldwide.

Core Research Programs

Two Foundational Therapeutic Programs

CIREN's scientific work is organized around two original therapeutic programs, each with an active research agenda.

Neurological Restoration

The flagship program, based on a Neuro-Restorative, Multifactorial, Intensive, and Personalized treatment technology. Research focuses on neuroplasticity, intensive rehabilitation protocols, and the integration of neurosurgical, pharmacological, and rehabilitative approaches across six specialized pathology clinics.

NeuroplasticityIntensive RehabilitationStereotactic Neurosurgery

REBIOGER — General Biological Restoration

A biological restoration program aimed at aging and systemic deterioration. Research explores integrative approaches to biological restoration alongside the neurological program.

Medical Achievements

Notable Scientific Contributions

Selected contributions from CIREN's clinical and research work. Specific statistics and claims are published only with supporting evidence.

Selective Dorsolateral Subthalamotomy

A world-first surgical innovation developed at CIREN for the treatment of Parkinson's disease, using stereotactic minimally-invasive neurosurgery with automated planning and neurophysiological verification.

NeuralCIM® (NeuroEPO) Research

Clinical research on a NeuroEPO-derived medication for neurological conditions, including the ATHENEA randomized clinical trial for mild-to-moderate Alzheimer's disease, published in Alzheimer's Research & Therapy (2023).

Stem Cell Research Program

Ongoing research into stem cell applications for neurological conditions. Stem cell treatment is restricted to research protocols and is not available as a regular clinical treatment.

Intensive Rehabilitation Protocols

Development of personalized, multidisciplinary neuro-rehabilitation delivered in structured cycles, integrating physiotherapy, occupational therapy, and cognitive rehabilitation.

Six Specialized Clinics

Research and clinical care organized across six specialized pathology clinics, each focused on a defined neurological condition group.

ISO 9000 Quality System

A quality control system based on ISO 9000 standards applied to clinical and research processes.

Several historical statistics and achievement claims are pending verification against primary sources. This page is updated as evidence is confirmed.
