Does Ketamine Therapy Work for People with ADHD?
November 9, 2025
When standard ADHD medications fail to provide adequate relief, ketamine therapy offers an alternative approach. While still experimental for Attention Deficit Hyperactivity Disorder (ADHD), ketamine intranasal infusion therapy works differently than traditional stimulants by targeting glutamate pathways instead of dopamine.
This article examines ketamine’s potential benefits for treatment-resistant ADHD, comparing its effectiveness to conventional medications, explaining possible risks, and outlining what to expect during treatment.
Read on to learn everything needed to make an informed decision about whether this emerging therapy might be right for your situation.
Key takeaways
- Ketamine infusion therapy for ADHD doesn’t have FDA approval and insurance coverage, with limited research compared to traditional stimulants.
- Effects vary widely between patients, typically lasting hours to days, with some reporting improved calm and focus, as well as emotional regulation.
- Unlike stimulants targeting dopamine, ketamine affects glutamate pathways by blocking NMDA receptors (also known as the NMDA antagonists) in the glutamate system. This promotes the creation of new neural connections, which leads to positive cognitive effects.
- Intranasal ketamine infusion therapy is best suited for treatment-resistant ADHD with comorbid depression or anxiety due to ketamine’s established antidepressant benefits.
- Marpa Minds is a ketamine clinic that offers personalized assessment and coordinates with your existing healthcare team in a supportive clinical setting.
What is ADHD?
ADHD is a brain condition that affects how you pay attention, control impulses, and manage activity levels. This means your brain processes information differently, making it harder to focus, sit still, or think before acting.
ADHD shows up in three main ways. Each type affects daily life differently:
- ADHD-Inattentive type: You struggle to focus on tasks, forget things often, and get easily distracted
- ADHD-Hyperactive-impulsive type: You feel restless, fidget constantly, and act without thinking
- ADHD-Combined type: You experience both attention problems and hyperactivity
Most people with ADHD take stimulant medications like Adderall or Ritalin. These drugs increase dopamine and norepinephrine in your brain to help with focus and impulse control.
Can ketamine help with ADHD symptoms?
Ketamine therapy for ADHD is still experimental and not FDA-approved. This means insurance coverage for ketamine therapy won’t apply for ADHD, and research is limited compared to traditional treatments.
Some clinics and clinical studies are already exploring ketamine for people who haven’t found relief with standard ADHD medications (as well as ketamine therapy effectiveness in other mental disorders, like bipolar disorder, post-traumatic stress disorder, obsessive-compulsive disorder, and so on).
The interest comes from ketamine’s unique way of working in the brain — it affects glutamate instead of dopamine like traditional ADHD drugs.
Mechanism overview
Unlike other ADHD drugs, Ketamine works differently: it helps brain connections, which consequently helps cognitive processes and the executive function.
Specifically, the mild psychedelic effects of ketamine block NMDA receptors in your brain. These receptors control the N-methyl-D-aspartate receptors (glutamate receptors), which are brain chemicals that help with learning and memory formation.
Traditional ADHD medications work differently. They boost dopamine and norepinephrine to improve attention and reduce hyperactivity. Ketamine’s glutamate approach might help ADHD symptoms through different brain pathways.
Low-dose ketamine for ADHD
Low-dose ketamine uses much smaller amounts than what doctors use for surgery. In mental health treatment, these doses aim to help your brain without causing major side effects.
The exact dosing for ADHD is still being studied, but a medical professional specialized in clinical psychiatry and this type of treatment can advise you, according to your medical history.
Does ketamine make ADHD worse or better?
Ketamine affects ADHD symptoms differently for each person. Some people feel calmer and more focused after treatment. Others experience temporary attention problems during or after sessions, largely due to the dissociative properties of ketamine.
Your response depends on several factors:
- Brain chemistry: How your individual brain responds to glutamate changes
- Symptom type: Whether you have more attention or hyperactivity issues
- Other conditions: If you also have depression or anxiety
- Treatment timing: Effects can vary throughout the day after treatment
The effects are usually temporary. Any improvements or worsening of symptoms typically last hours to days rather than weeks.
Ketamine vs Adderall and other ADHD medications
Ketamine and traditional ADHD medications work through completely different mechanisms. Understanding these differences helps you make informed treatment decisions.
| Aspect | Traditional ADHD medications | Ketamine therapy |
|---|---|---|
| FDA approval | Yes, specifically for ADHD | No ADHD approval |
| How it works | Increases dopamine/norepinephrine | Blocks NMDA receptors |
| How you take it | Daily pills | Clinical sessions (intranasal ketamine) |
| Research support | Decades of studies | Limited ADHD research |
| Insurance coverage | Usually covered | Not covered for ADHD |
Ketamine and Adderall
Taking ketamine and Adderall together requires extreme caution. These substances can interact and affect your heart rate, blood pressure, and brain function.
If you’re considering both treatments, you need coordinated care from experienced providers. Marpa Minds works with your existing psychiatrist to ensure safe treatment planning when multiple medications are involved.
Ketamine or traditional stimulants?
Ketamine isn’t meant to replace your ADHD medication. It might help when traditional treatments haven’t worked, especially if you also have depression.
The choice depends on your specific situation. Some people try ketamine after multiple failed medication trials. Others use it alongside existing treatments under careful supervision.
What to expect from ketamine therapy for ADHD
Ketamine therapy happens in a medical setting with trained professionals monitoring you throughout treatment. Each session follows specific safety protocols.
You’ll typically need multiple sessions over several weeks, but keep in mind at Marpa Minds, we design bespoke treatments to fit each patient’s specific situation. The first few sessions help determine how you respond to treatment. Later sessions build on this foundation while tracking any benefits or side effects.
Session steps
Here’s what happens during a typical ketamine therapy session. Each step ensures your safety and comfort:
- Pre-treatment evaluation: Your medical team reviews your health history and current medications
- Preparation: Staff check your vital signs and prepare a comfortable treatment space
- Administration: You receive ketamine through an IV or nasal spray while being monitored
- Monitoring: Medical staff observe you during treatment and for about two hours after
- Follow-up: Your team assesses how you’re feeling and plans your next session
5 key benefits of low-dose ketamine for ADHD
These potential benefits come from early research and patient reports. Remember that individual results vary significantly, and more studies are needed.
1. Increased calm
Ketamine may reduce the restless feeling that comes with hyperactive ADHD. Some people report feeling more settled in their bodies after treatment.
This calming effect might last several days. It could help if constant movement and fidgeting interfere with your daily life.
2. Rapid mood support
Many people with ADHD also struggle with depression. Ketamine’s proven antidepressant effects can lift mood within hours or days.
When your mood improves, other ADHD symptoms might become more manageable. Marpa Minds has seen how addressing depression can create space for tackling attention issues.
3. Potential focus improvement
Some patients report clearer thinking after ketamine therapy. However, this benefit isn’t consistent — others experience temporary brain fog.
Focus improvements, when they occur, might relate to reduced anxiety or better mood rather than direct ADHD effects.
4. Reduced anxiety
Anxiety often makes ADHD symptoms worse. Ketamine can reduce anxiety quickly, which might indirectly help with concentration.
Lower anxiety means less mental noise competing for your attention. This can make it easier to complete tasks and stay organized.
5. Combination with other treatments
Ketamine works well as part of a comprehensive treatment plan. You can continue other therapies while exploring ketamine’s benefits.
This integrated approach lets you keep what’s working while adding new tools. Coordination between providers ensures all treatments support each other.
Possible risks and precautions
Ketamine therapy carries risks you should understand before starting treatment. Being informed helps you weigh potential benefits against possible downsides.
Common side effects during and after treatment include:
- Nausea and dizziness: Usually mild and temporary
- Dissociation: Feeling disconnected from your body or surroundings
- Attention changes: Temporary worsening of focus
- Blood pressure changes: Requires monitoring during treatment
People with ADHD might be extra sensitive to ketamine’s effects on attention and perception. Working with experienced providers like Marpa Minds ensures proper screening and monitoring throughout your treatment journey.
How long does ketamine treatment for ADHD last?
Ketamine’s effects on ADHD symptoms vary widely between individuals. Most people need repeated sessions to maintain any benefits.
A typical treatment course involves:
- Initial phase: 2-3 sessions per week for 2-3 weeks
- Maintenance phase: Sessions every few weeks or monthly
- Effect duration: Benefits may last days to weeks after each session
This differs from daily ADHD medications that need consistent dosing. The experimental nature of ketamine for ADHD means optimal schedules are still being determined.
Can you use ketamine and Adderall together?
Using ketamine and Adderall together is possible but requires careful medical oversight. These medications can interact in complex ways.
Your treatment team needs to:
- Monitor vital signs: Both drugs affect heart rate and blood pressure
- Adjust dosing: Stimulants might need modification during ketamine treatment
- Track symptoms: Watch for unexpected reactions or side effects
- Coordinate care: Ensure all providers communicate about your treatment
