Everything You Need to Know About Ketamine Therapy: A Modern Approach to Brain Health and Pain
Mar 26, 2026
Ketamine has gained increasing attention in recent years as a promising option for people struggling with persistent mood symptoms, chronic stress, and conditions that haven’t responded well to traditional treatments. If you’ve been hearing about ketamine and wondering what it actually is, how it works, or whether it might be right for you, you’re not alone.
At Ki Ketamine, part of the New England Institute for Neurology & Headache, ketamine therapy is approached through a neuroscience-based, medically supervised lens, focused on safety, personalization, and long-term brain health.
Ketamine is a medication that has been safely used in medical settings for over 50 years, originally as an anesthetic in operating rooms and emergency medicine. At much lower, carefully controlled doses, ketamine has been shown to have meaningful effects on brain systems involved in mood regulation, stress response, pain processing, and cognitive flexibility.
Unlike many psychiatric medications that must be taken daily, ketamine is administered intermittently in a monitored clinical setting. This allows for precise dosing, careful oversight, and a treatment plan that is tailored to the individual rather than standardized across patients.
Ketamine works differently from traditional antidepressants. Rather than acting primarily on serotonin, ketamine targets the brain’s glutamate system, which plays a central role in learning, memory, and neural communication.
By influencing this system, ketamine works below the surface at the cellular and neural level, helping the brain:
Many patients describe ketamine as creating a sense of mental flexibility or reset, allowing the brain to move out of entrenched pathways and respond more effectively to therapy, lifestyle changes, and everyday stressors. Notably, ketamine often works more rapidly than traditional medications, with some individuals noticing changes within hours or days.
As neurologist and headache specialist Dr. Peter McAllister has discussed in his published work, ketamine’s effects on glutamate signaling and neuroplasticity help explain why it may be effective when other treatments fall short. Rather than simply masking symptoms, ketamine appears to promote meaningful changes in how the brain processes mood, stress, and pain—offering a unique therapeutic option for patients with more complex or treatment-resistant presentations.
When administered in a medical setting by trained professionals, ketamine is considered very safe. Side effects are typically mild and short-lived and may include temporary dissociation, nausea, fatigue, or changes in perception.
Patients are monitored before, during, and after treatment to prioritize safety and comfort at every step.
At Ki Ketamine, treatment is never one-size-fits-all. Our model is built around thoughtful evaluation, individualized planning, and ongoing support.
Every patient begins with a comprehensive evaluation to ensure ketamine therapy is appropriate, safe, and aligned with their medical history and goals.
Dosing and treatment plans are customized based on the individual, not a preset protocol. Adjustments are made thoughtfully and intentionally as treatment progresses.
Care does not end after an infusion. We provide close follow-up to track response, guide next steps, and support patients as improvements translate into daily life.
A key component of our program is dedicated 1:1 nursing support, ensuring patients feel safe, monitored, and supported throughout their treatment experience.
Ki Ketamine is backed by the clinical expertise of the New England Institute for Neurology & Headache, bringing a neurologist-led, evidence-based approach to ketamine therapy.
What sets our program apart:
Ketamine may be worth exploring if you’ve been struggling with persistent symptoms, emotional fatigue, or stress that hasn’t improved with traditional treatments. It is not a one-size-fits-all solution, but for the right patient, it can be a meaningful part of a broader treatment plan.
