Center of Excellence in Neuropathy Treatment and Research (CENTR)
At our center, we are dedicated to providing comprehensive care, conducting cutting-edge research, and advancing the understanding and treatment of neuropathy. With an expert team of physicians, healthcare professionals, and researchers, we strive to improve the lives of individuals living with neuropathy and contribute to the development of innovative therapies.

Neuropathy can be a debilitating condition, causing a range of symptoms such as numbness, tingling, pain, and muscle weakness. We understand the challenges and impact this condition can have on your daily life, and we are committed to delivering personalized, evidence-based care to address your unique needs and restore your quality of life.
Our center is at the forefront of neuropathy research. We are actively exploring new diagnostic techniques and treatment options. Through continued research, we aim to discover the underlying causes of neuropathy and identify novel therapies. Our research not only benefits our patients but also contributes to the broader scientific community’s understanding of this complex condition.
We invite you to explore our website to learn more about our team, services, ongoing research initiatives, and patient resources. Whether you are seeking a diagnosis, exploring treatment options, or interested in participating in clinical trials, we look forward to partnering with you to achieve optimal neurological health and a brighter future.
