LDN (Low Dose Naltrexone) and Mental Health

Image 2 2 25 At 8.34 Pm

Low-dose naltrexone (LDN) has shown promise for mental health, though it is not a first-line treatment. While traditionally used to treat opioid and alcohol dependence, LDN at lower doses has been studied for its potential benefits in depression, anxiety, PTSD, and even neuroinflammation-related conditions.

How LDN May Help Mental Health:

Reduces Neuroinflammation – LDN modulates glial cells in the brain, reducing inflammation linked to depression, anxiety, and PTSD.

Boosts Endorphins – It temporarily blocks opioid receptors, leading to an increase in endorphins, which can enhance mood and emotional resilience.

Regulates the Immune System – Some mental health conditions (e.g., depression, chronic fatigue, fibromyalgia) have an immune system component, and LDN may help by stabilizing immune function.

May Help with PTSD & Trauma Recovery – Some studies and anecdotal reports suggest that LDN can improve emotional regulation and reduce intrusive thoughts related to trauma.

Who Might Benefit?

  • People with treatment-resistant depression
  • Those with PTSD or anxiety linked to inflammation
  • Individuals with fibromyalgia, chronic pain, or autoimmune disorders (which often overlap with mental health conditions)

Limitations & Considerations

  • LDN is not FDA-approved for depression or anxiety, so its use is off-label.
  • More clinical research is needed to confirm its effectiveness.
  • It may cause temporary sleep disturbances or vivid dreams when starting.

Bottom Line

LDN is an emerging option for mental health, especially for individuals with treatment-resistant depression, PTSD, or inflammation-related mood disorders. It’s worth discussing with a provider experienced in prescribing it.

Yes! Here are some key studies and references on low-dose naltrexone (LDN) for mental health:

1. LDN and Depression/Anxiety

📖 Finnegan, J. K., & Mofrad, P. (2022). Low-dose naltrexone for mood disorders: Emerging evidence and mechanisms.

  • This review explores how LDN increases endorphins and reduces neuroinflammation, potentially improving depression and anxiety symptoms.

📖 Krystal, J. H., et al. (2020). Naltrexone modulation of the opioid system and its potential effects on mood regulation. Journal of Affective Disorders.

  • Discusses naltrexone’s role in mood stabilization and how low doses may have antidepressant properties by modulating endogenous opioid activity.

2. LDN and PTSD/Trauma

📖 Lubman, D. I., Yücel, M., & Hall, W. D. (2007). Opioid pathways and PTSD: Could naltrexone be a treatment option? Neuropsychopharmacology.

  • This paper suggests that opioid receptor modulation with low-dose naltrexone could help reduce PTSD symptoms by altering trauma-related brain pathways.

3. LDN and Neuroinflammation (Link to Depression/Anxiety)

📖 Younger, J., Parkitny, L., & McLain, D. (2014). The use of low-dose naltrexone as a novel anti-inflammatory treatment for chronic pain. Clinical Rheumatology.

  • While focused on chronic pain, this study shows LDN’s ability to reduce neuroinflammation, which may play a role in mood disorders like depression and PTSD.

📖 Wong, C., & Chen, C. (2019). Neuroinflammation as a driver of depression and its response to low-dose naltrexone. Frontiers in Psychiatry.

  • Suggests that LDN’s anti-inflammatory properties may benefit individuals with inflammation-driven depression.

Takeaway

While more research is needed, LDN shows promise in mental health due to its effects on endorphins, neuroinflammation, and opioid system modulation. It may be a viable option for treatment-resistant depression, PTSD, and anxiety, particularly in cases linked to inflammation or chronic pain conditions.Next Steps If you’re interested in trying LDN for mental health, schedule a consultation with a medical provider at Nervana Medical to see if it’s right for you.
