What Is Ketamine Infusion Therapy & How Does It Affect The Brain?

What Is Ketamine Infusion Therapy & How Does It Affect The Brain?

The Albany Clinic • May 3, 2023

Ketamine is a medication that was first developed as an anesthetic in the 1960s. It has been used for decades to treat pain, sedate patients during medical procedures, and induce anesthesia for surgery. In recent years, ketamine has gained attention as a potential treatment for mental health conditions, such as depression, anxiety, and post-traumatic stress disorder (PTSD).

One form of ketamine treatment that has become increasingly popular is ketamine infusion therapy. In this blog, we are going to explore what ketamine infusions do to your brain, and how they may help those struggling with mental health conditions.

What are Ketamine Infusions?

Ketamine infusion therapy involves the administration of ketamine directly into the bloodstream through an IV (intravenous) line. The dose of ketamine used in this therapy is much lower than what is typically used for anesthesia. The infusion is typically given over the course of 40-60 minutes, during which the patient is closely monitored by a healthcare provider. The effects of ketamine infusion therapy are often felt within minutes to hours after the infusion is completed.

What Are Ketamine Infusions Used For?

While ketamine is primarily known as a dissociative anesthetic, it has been found to have therapeutic benefits for a range of mental health conditions, including depression, anxiety, PTSD, and bipolar disorder. Ketamine infusion therapy has also been used to manage chronic pain conditions, such as fibromyalgia and migraines. In addition, emerging research suggests that ketamine may be effective in treating addiction and obsessive-compulsive disorder (OCD).

Overall, ketamine infusion therapy is a promising treatment option for individuals struggling with mental health and other chronic conditions.

How Do Ketamine Infusions Work?

To understand how ketamine infusions work in the brain, it is crucial to first understand some basic neurochemistry. In the brain, neurons communicate with each other through the release and uptake of chemicals called neurotransmitters. One of these neurotransmitters, called glutamate, is involved in many important brain functions, including learning, memory, and mood regulation.

Ketamine works by blocking a specific type of receptor for glutamate , called the N-methyl-D-aspartate (NMDA) receptor. By blocking these receptors, ketamine leads to an increase in the levels of another neurotransmitter called brain-derived neurotrophic factor (BDNF). BDNF is a protein that is involved in the growth and survival of neurons, and it has been implicated in the development of depression and other mood disorders.

Studies have shown that ketamine infusions can lead to rapid increases in BDNF levels in the brain, which may be one reason why it is effective in treating depression and other mental health conditions. In addition to increasing BDNF levels, ketamine has also been shown to increase the formation of new synapses, or connections between neurons, in certain brain regions.

Another way that ketamine infusions may affect the brain is by altering the activity of certain brain networks.

Functional magnetic resonance imaging (fMRI) studies have shown that ketamine infusions can lead to changes in the activity of the default mode network (DMN), a set of brain regions that are active when we are not engaged in any particular task. The DMN has been implicated in self-referential thinking and rumination, which are common features of depression and other mood disorders.

By altering the activity of the DMN, ketamine may help to break negative thought patterns and promote more positive thinking. In addition to its effects on the DMN, ketamine has also been shown to increase activity in the prefrontal cortex, a brain region involved in decision-making, impulse control, and other higher cognitive functions.

The Importance of Ketamine Infusion Therapy

For many individuals, depression, anxiety, PTSD, and other mood disorders can significantly impact their quality of life and lead to feelings of hopelessness and despair. Ketamine infusion therapy offers a new treatment option that can help to alleviate symptoms and improve overall functioning.

By promoting the growth of new synapses and altering the activity of certain brain networks, ketamine infusion therapy may also offer long-term benefits that can help individuals maintain their mental wellness over time.

Stellate Ganglion Block (SGB) is an emerging mental health treatment that targets key mechanisms linked to depression. In this article, we’ll discuss the science behind SGB and its potential benefits. If you or someone you know is struggling with depression, this information can help you make an informed decision about whether SGB might be the right option. What is a Stellate Ganglion Block (SGB)? What is the Stellate Ganglion? The stellate ganglion is a cluster of sympathetic nerves located on each side of the neck near the first rib. These nerves are part of the autonomic nervous system, which controls automatic body functions like heart rate, blood pressure, and digestion. The term "stellate" means "star-shaped" because the ganglion often looks like a star under a microscope. It helps regulate the body's stress response by controlling norepinephrine, a chemical that triggers the fight-or-flight reaction. When this system becomes overactive, it can cause various physical and psychological problems, including depression. Stellate ganglion block (SGB) therapy may help by reducing the activity of the stellate ganglion, calming the fight-or-flight response, and lessening the damaging effects of prolonged nervous system stress. How Does Stellate Ganglion Block Work? Stellate Ganglion block (SGB) is when a local anesthetic is injected near the stellate ganglion. These drugs inhibit transmission between nerve cells, dampening activity in the ganglion. They typically include lidocaine, bupivacaine, or mepivacaine, which are sometimes combined with a steroid medication. Patients may also receive another medication to relax them before treatment. SGB is typically performed using ultrasound guidance . The injection process lasts no more than 10 minutes, but patients will motinoted for another 30-45 minutes after treatment to ensure their safety. How Does Stellate Ganglion Block Work for Depression? Chronic stress is a major contributor to depression and is often linked to an overactive sympathetic nervous system. People with depression commonly show high levels of cortisol, a hormone that plays a key role in the body's stress response, in their blood stream. Cortisol is helpful in small doses, but when chronically elevated, it can disrupt neural circuits in the brain. Excessive cortisol can lead to: Neurotoxicity - Cortisol can be toxic to nerve cells, especially in the hippocampus, which is crucial for memory and emotional regulation. Overinflammation - Cortisol increases the activity of the body’s natural defense system, resulting in the system causing damage to nerve cells. Impaired synaptic plasticity - Cortisol inhibits the capacity for the brain to “re-wire” itself. This makes it harder for people to adapt to stressful situations and learn new patterns of behaviour. Disrupted sleep - High cortisol can prevent people from sleeping well. During sleep, restorative biological processes occur in the brain, and excess cortisol can prevent these from happening. SGB decreases sympathetic nervous system activity, which can reduce cortisol levels. This can help restore function in brain areas and pathways associated with positive mood, emotional regulation, and stress resilience. Evidence Supporting SGB for Depression To date, there’s very limited evidence supporting the use of SGB for depression. One pilot study found that SGP significantly reduced depression symptoms in people with treatment-resistant depression (TRD) and was well-tolerated. However, there was no significant difference to the placebo group and the sample size was very small. Nonetheless, multiple lines of research show that SGB can alleviate symptoms of post-traumatic stress disorder (PTSD), which shares similarities with depression. In a trial of SGB for PTSD , participants reported significantly lower scores of depression following treatment. Who May Benefit from SGB for Depression? SGB is primarily utilized for treating PTSD, so individuals with PTSD who also experience depression may find SGB beneficial. Additionally, SGB has shown potential in alleviating anxiety symptoms, suggesting it may be advantageous for those dealing with both depression and anxiety. Because SGB isn’t approved by the FDA, it is typically only used when standard treatments like antidepressants and psychotherapy haven’t worked. SGB is an “off-label” treatment, much like ketamine therapy or brain stimulation therapies. Importantly, SGB may not be suitable for everyone because of medical reasons. Contraindications include: Recent myocardial infarction Coagulopathy or anticoagulant therapy Glaucoma Pre-existing contralateral phrenic nerve palsy Severe emphysema Cardiac conduction block Potential Risks and Side Effects of SGB Common Side Effects Most side effects of SGB are temporary and resolve as the anesthetic wears off. These may include: Hoarseness or Voice Changes: The proximity of the stellate ganglion to nerves controlling the voice box can lead to temporary hoarseness. Drooping Eyelid (Ptosis): Temporary drooping of the eyelid on the side of the injection may occur. Red or Bloodshot Eyes: Some individuals may notice redness in the eyes following the procedure. Watery Eyes and Nasal Congestion: Increased tearing and nasal stuffiness are possible but typically short-lived. Sensation of a Lump in the Throat and Difficulty Swallowing: Some individuals may experience a sensation of a lump in the throat and have difficulty swallowing after the procedure. Warmth or Tingling in the Arm or Hand: A warm or tingling sensation in the affected limb may be experienced temporarily. Although uncommon, some individuals may experience more serious complications, such as nerve damage, seizures, and allergic reactions. Given the potential risks, patients interested in SGB at the Albany Clinic will have an in-depth consultation with one of our qualified healthcare professionals before undergoing treatment. They can assess your medical history, current health status, and the potential benefits and risks of the procedure in your specific case.

Finding effective depression treatment can be challenging, especially when cost and insurance coverage add to the stress. Fortunately, for individuals in Illinois, several advanced, insurance-backed options are available beyond traditional antidepressants and therapy. This article explores innovative treatments for depression that are available at our Albany Clinic in Carbondale. Addressing the Need for Affordable Depression Relief in Illinois Depression remains a significant public health concern in Illinois. In 2023, data showed that 18.1% of all adults in the state had a doctor's diagnosis of a depressive disorder . Traditional first-line treatments for depression include medications such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). However, these are not universally effective; approximately one-third of patients are treatment-resistant. Even when these medications do work, they often take a long time to produce noticeable improvements, and unpleasant side effects can deter their use. Talk therapies , such as cognitive behavioral therapy (CBT) and psychodynamic therapy, are also strongly recommended. These treatments can have hugely beneficial effects, but it can require a lot of time commitment for results to show. Moreover, not all therapists accept insurance–especially for those practicing more specialized forms–making the treatment inaccessible for many. Spravato (Esketamine) for Depression What is Spravato, and how does it work? Spravato is an FDA-approved nasal spray that contains esketamine, a derivative of ketamine. Like ketamine, esketamine treats depression by interacting with NMDA receptors , proteins that play a key role in learning and memory. This interaction triggers several neurological processes, including neuroplasticity —the strengthening and forming of connections between nerve cells. Enhanced plasticity may improve the function of nerve circuits responsible for mood regulation, increasing overall well-being. A typical Spravato treatment involves sessions administered under medical supervision, starting with twice-weekly doses and then tapering as appropriate. Whereas antidepressants typically take around four weeks to show an effect, Spravato can have rapid action at alleviating symptoms. A study found that Spravato significantly reduced depression symptoms compared to a placebo drug within just 24 hours of administration. Does Insurance cover Spravato? Due to its FDA approval, Spravato is covered by most major insurance plans in Illinois, including Medicare and Medicaid. However, only patients with a formal diagnosis of treatment-resistant depression (TRD) or major depressive disorder with suicidal ideation (MDSI) are eligible for the treatment. While the medication is usually covered by insurance, patients may still have out-of-pocket costs , including copays , deductibles , and pre-treatment medical evaluations . Your exact expenses will depend on your specific insurance plan. At the Albany Clinic, we’re here to help you understand your costs and maximize your coverage. Transcranial Magnetic Stimulation (TMS) Therapy What is TMS, and how does it work? TMS therapy is a noninvasive procedure that uses magnetic fields to stimulate underactive regions of the brain associated with mood regulation. In depression, TMS targets the dorsolateral prefrontal cortex (DLPFC) , which is often less active in individuals with the condition. TMS therapy works by: Inducing electrical activity in neurons , prompting the release of neurotransmitters involved in mood and motivation. Increasing the activity of neural circuits responsible for mood regulation. Enhancing neuroplasticity , potentially “re-wiring” nerve circuits associated with unhealthy thinking and behavior. The treatment protocol typically consists of daily sessions over several weeks. Each session lasts about 20-40 minutes, during which patients remain awake and alert. Does insurance cover TMS? Since TMS therapy is FDA-approved, some major insurance providers in Illinois cover costs, but unfortunately, the state’s Medicaid does not. If you're considering TMS, check with your insurance provider to see if your plan includes coverage, as eligibility and benefits vary. At the Albany Clinic, we're here to help clarify details and explore options to make treatment more affordable. IV Ketamine Infusion Therapy What is an IV ketamine infusion and how does it work? IV ketamine infusion therapy involves administering ketamine intravenously at sub-anesthetic doses . This approach has shown rapid and robust antidepressant effects, especially in individuals with treatment-resistant depression. IV ketamine shares the same mechanism as Spravato but tends to have more rapid-acting effects. A standard course includes multiple infusions over a set period, with each session lasting approximately one hour. Does insurance cover IV ketamine? Unlike Spravato and TMS, IV ketamine infusion therapy is not FDA-approved for depression treatment and instead is used “ off-label .” This means most insurance plans don’t accept ketamine, and coverage is limited. However, some insurance companies may reimburse some of the treatment costs, such as the evaluation and management part. At the Albany Clinic, we’ll provide you with all the documentation to submit a claim to your insurance provider, but full payment is required before each procedure. Navigating Insurance for Depression Treatment Understanding insurance coverage for depression treatments can be complex. Here are steps to help streamline the process: Verify Coverage : Contact your insurance provider to inquire about treatment coverage specifics. Some insurers require a history of treatment failures with traditional antidepressants before approving coverage for these advanced therapies. Obtain Pre-Authorization : Many insurers require pre-authorization for certain treatments. Ensure all necessary approvals are secured before initiating therapy. The Albany Clinic's administrative team can assist in submitting pre-authorization requests. Understand Financial Responsibilities : Clarify any co-pays, deductibles, or out-of-pocket expenses associated with your treatment plan. Consult Our Team : The Albany Clinic's administrative staff is experienced in navigating insurance processes and can assist you in understanding and managing the financial aspects of your treatment. We also provide financial counseling to help patients explore payment plans and reimbursement options.
