Neuroactive steroids and PTSD treatment

Area of Science:

• Neuroendocrinology
• Psychopharmacology
• Translational Psychiatry

Background:

• Neuroactive steroids play a role in stress adaptation and are implicated in post-traumatic stress disorder (PTSD).
• Alterations in neuroactive steroid levels and their targets are observed in individuals with PTSD.
• Significant variability exists in neuroactive steroid system dysfunction among PTSD subpopulations.

Purpose of the Study:

• To review early therapeutic translation efforts for neuroactive steroids in PTSD.
• To explore the potential of neuroactive steroids as novel therapeutics for PTSD.
• To highlight the need for personalized treatment approaches in PTSD.

Main Methods:

• Review of pre-clinical and clinical studies on neuroactive steroids and PTSD.
• Analysis of factors contributing to variability in neuroactive steroid system dysfunction.
• Examination of interventional studies involving glucocorticoids and other neuroactive agents.

Main Results:

• Glucocorticoid administration shows potential in preventing PTSD post-trauma.
• Neuroactive steroids like 17β-estradiol and GABAergic agents can facilitate fear extinction and retention.
• Dose and timing of administration are critical factors for therapeutic efficacy.

Conclusions:

• Neuroactive steroid-based therapeutics offer a promising avenue for PTSD treatment.
• Individualized treatment strategies, considering specific neurosteroid abnormalities, are essential.
• Development of methods to identify individual neurosteroid system function is needed for precision medicine in PTSD.
