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.

Dysautonomia lifestyle recommendations
  • Rise slowly from lying to sitting to standing
  • Drink 2.5 – 3 liters of water per day. Approximately half of this should be electrolyte-rich fluid like Gatorade, Powerade, or dissolvable electrolyte packets
  • Increase salt intake up to 10 grams per day
  • Exercise approximately 30 minutes a day with moderate aerobic activity. Recumbent bike is often well-tolerated in patients with autonomic dysfunction
  • Elevate head of bed with bed rises or cinder block 4-6 inches
  • Eat small meals throughout the day rather than 3 large meals
  • Compression stockings can be purchased online or at your local pharmacy
