Neuro-Immunological Disease Registry
Japan Neuro-Immunology Association :JANIMA is a research organization which analyzes patients’ clinical and genetic information with a view to striving to overcome neuroimmunological diseases.
The cooperation of many patients propels progress toward overcoming these diseases.


About JANIMA
JANIMA is an abbreviation for the Japan Neuro-Immunology Association, and acts as an organization to promote and operate the Neuro-Immunological Disease Registry in Japan.
Neuroimmunological diseases are a collective term for conditions in which the immune system attacks the nervous system. Autoimmune responses cause inflammation and nerve damage, resulting in various symptoms including muscle weakness and numbness.
The number of patients with neuroimmunological diseases is small, classifying them as rare diseases. Research to elucidate the mechanisms and characteristics of these diseases is essential to treating and overcoming them. However, for rare diseases it is difficult to collect sufficient clinical data and biological samples (such as blood) for research, and this tends to hinder progress.
To address this, at the initiative of the Japanese Society for Neuroimmunology, JANIMA (Neuroimmunological Disease Registry) utilizes a network of neurologists to collect data and biological samples from patients with neuroimmunological diseases nationwide. This enables research on a scale that was previously difficult and aims to achieve results that will lead to the treatment of rare diseases and the optimization of therapies.

Activities and Statistics
JANIMA collaborates with many stakeholders to promote and operate versatile activities.

【For Physicians and Researchers】
Building a nationwide network of neurologists
Through a nationwide network centered on major high-volume centers in Japan, we promote elucidation of the pathophysiology of rare diseases and development of new treatments.
Participating physicians can contribute to research using accumulated data and biological samples. Participation is possible even with small numbers of enrolled cases.
【For Companies】
Accumulation and utilization of high-quality data through collaboration with companies.
This registry envisions one of the largest-in the-world case enrollments and a high follow-up rate.
Because physicians nationwide cooperate with high awareness and aspiration and hold mutual trust and respect, high-quality clinical data and biological samples are collected and accumulated.
We use these real world data to flexibly respond to the needs for drug discovery, medical device development, and evidence generation related to neuroimmunological diseases, achieving mutually beneficial collaboration.
【For Patients】
Provide patients with the latest information about diseases.
As research advances on disease causes and mechanisms, the possibility of identifying the most suitable treatments for each patient expands.
Enrolling patients receive the latest information on diseases and introduction of opportunities of participating in clinical trials.
The number of enrolled patients
As a result of these diverse activities, the number of enrolled patients increases every year.
Number of registered patients
Thanks to our wide-ranging activities, the number of registered patients continues to grow each year.
