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.

Struggling with a social anxiety disorder (SAD) can feel isolating and overwhelming, especially when other medications haven’t proved effective. However, ketamine therapy offers a promising path forward, showing fast and significant relief from SAD symptoms. At The Albany Clinic in Albany, New York, we provide customized ketamine treatment plans designed to empower patients to overcome the challenges of SAD. Read on to explore the science and benefits of this transformative approach. Understanding Social Anxiety Disorder Social Anxiety Disorder (SAD), often referred to as social phobia, is a chronic mental health condition characterized by extreme fear and discomfort in social situations. While occasional nervousness in social settings is normal, social anxiety disorder is more persistent and can significantly disrupt daily life, relationships, and career opportunities. According to the National Institute of Mental Health (NIMH) , 7.1% of the U.S. population experiences social anxiety disorder annually. Recognizing the Symptoms of SAD The symptoms of social anxiety disorder can be grouped into three categories: emotional, behavioral, and physical. Emotional Symptoms: Intense fear of social interactions, particularly with strangers. Persistent worry about being judged or negatively evaluated. Excessive anxiety about upcoming social events, often for weeks in advance. Overwhelming self-consciousness in social environments. Behavioral Symptoms: Avoidance of social situations. Skipping school, work, or events to avoid social interaction. Relying on alcohol or other substances to ease anxiety in social settings. Physical Symptoms: Sweating, trembling, dry mouth, or muscle tension. Panic attacks in extreme cases. At The Albany Clinic, we understand the debilitating impact of these symptoms and offer ketamine therapy as a groundbreaking approach to address SAD. Our compassionate team is dedicated to creating personalized treatment plans tailored to each patient’s unique needs. How Ketamine Therapy Helps Treat Social Anxiety Ketamine has emerged as a promising treatment for social anxiety disorder due to its unique mechanism of action. Unlike traditional treatments, ketamine interacts with NMDA receptors in the brain, enhancing neuroplasticity —the brain’s ability to form new neural connections. This process can help improve brain function in areas related to stress and emotional regulation, potentially improving symptoms of SAD. Brain scanning experiments show ketamine alters connectivity in a brain region called the anterior insular cortex , which is thought to play a key role in social emotions. Studies suggest that this region may become dysfunctional in SAD, but ketamine could help restore its normal function and reduce SAD symptoms. Ketamine also lowers the activity of the amygdala , a brain region linked to fear and the body’s stress response. In people with anxiety, the amygdala is often overactive. Ketamine may help by calming this overactivity and reducing feelings of fear. Benefits of Ketamine for SAD Ketamine offers several benefits for treating SAD . One of its most significant advantages is its rapid action , often providing relief within hours, compared to the weeks or months traditional antidepressants can take. Additionally, ketamine has shown sustained effects , with a single dose sometimes improving symptoms for days or even weeks. Whereas common anti-anxiety medications, such as antidepressants, are used every day, ketamine is used more infrequently . A typical dosing regime involves twice-weekly sessions for the first four weeks, with more spaced-out sessions thereafter. This prevents people from developing tolerance to the drug, so they don’t experience withdrawal symptoms once they stop taking medication. However, ketamine does have an abuse potential , and ketamine addiction can lead to severe health consequences. For this reason, it’s essential to use ketamine in carefully controlled clinical environments under medical supervision, such as our clinic in Albany. Typical anti-anxiety medication is also associated with side effects that affect daily function, such as weight gain or sexual dysfunction . Ketamine, on the other hand, has mild side effects that generally wear off once the drug is cleared from the system. These include: Dizziness Decreased heart rate and blood pressure Drowsiness Nausea Research Supporting Ketamine for Social Anxiety A clinical trial from Yale University found ketamine infusions significantly decreased measures of social phobia in anxiety patients, compared to a placebo drug. The difference in improvement was significant from two days post-treatment and lasted up to the two-week follow-up. In another study from the University of Otago, patients with both generalized anxiety disorder (GAD) and SAD had significantly improved symptoms two weeks following ketamine treatment. These patients had been previously non-responsive to other therapies. Is Ketamine Therapy Right for You? Ketamine therapy is not suitable for everyone, but it can be highly effective for those who have not found relief with traditional treatments. You may be a good candidate if: You have been diagnosed with SAD, or another severe form of anxiety Conventional medications or therapies have not provided sufficient relief You are seeking a treatment with faster results However, ketamine therapy may not be recommended if you have: A current or past history of substance abuse You have specific liver or heart conditions You have a history of psychosis At The Albany Clinic, our experienced providers will carefully evaluate your medical history to determine if ketamine therapy is the best option for you.
