Ketamine Infusion Therapy

Ketamine therapy is a revolutionary therapeutic approach to treating depression and anxiety disorders. Ketamine therapy is significantly more effective than traditional pharmaceuticals, is very safe, and is usually life-changing.

Several scientific studies, including those conducted at Yale University and the National Institute of Mental Health, have shown that low dose intravenously administered ketamine can dramatically improve symptoms associated with depression and many anxiety disorders. Often, even when other treatments have failed to provide any relief, IV ketamine is effective.

Neural Health Therapies providers are ACLS certified and follow APA consensus guidelines for the administration of low-dose IV ketamine. All new patients have a series of six infusions  spaced over two or three weeks. Each infusion is dosed at 0.5 mg/kg  administered over 40 minutes. In  general, infusions are  painless and well tolerated. Most patients experience significant relief during the series and many remain symptom free for extended periods of time following the initial treatment protocol.

Ketamine therapy impacts both mood and anxiety disorders with positive treatment outcomes for the following diagnoses:

Chronic and Treatment Resistant Depression

Bipolar Depression

Post Traumatic Stress Disorder (PTSD)

Obsessive Compulsive Disorder (OCD)

Post-Partum Depression

All Anxiety Disorders

Deep Transcranial Magnetic Stimulation

Neural Health Therapies offers BrainsWay's dTMS, a unique, patented treatment method that stimulates deep and broad neural targets. dTMS is a medical procedure that works by delivering highly focused MRI-strength magnetic pulses to noninvasively stimulate the brain. The treatment session is conducted using a helmet called a “coil” that delivers energy to the brain using pulsed “magnetic fields.” These magnetic fields are similar to those used in magnetic resonance imaging (MRI) machines. Patients being treated with dTMS do not require anesthesia or sedation. They remain awake and alert and return to work or their daily routine immediately after each treatment.

Neural Health Therapies offers this service to patients with treatment resistant depression and OCD.

Coordination with Your Providers

While Neural Health Therapies does not require that you are referred by your current treatment provider, we believe it is important that we work together with your existing network in order to offer the highest level of care. We will maintain contact with your current primary care physician, psychiatrist and/or therapists every step of the way.

Our services are not meant to be stand alone, they should rather be viewed as additional augmentative interventions

as part of your larger treatment plan.
