Abstract

The only evidence-based behavioral treatment for anxiety and stress-related disorders involves desensitization techniques that rely on principles of extinction learning. However, 40% of patients do not respond to this treatment. Efforts have focused on individual differences in treatment response, but have not examined when, during development, such treatments may be most effective. We examined fear-extinction learning across development in mice and humans. Parallel behavioral studies revealed attenuated extinction learning during adolescence. Probing neural circuitry in mice revealed altered synaptic plasticity of prefrontal cortical regions implicated in suppression of fear responses across development. The results suggest a lack of synaptic plasticity in the prefrontal regions, during adolescence, is associated with blunted regulation of fear extinction. These findings provide insight into optimizing treatment outcomes for when, during development, exposure therapies may be most effective.

  • Cross-species evidence suggests that extinction is diminished during adolescence relative to childhood and adulthood.

    “Moreover, cross-species evidence suggests that extinction is diminished during adolescence relative to childhood and adulthood (10).”
  • Fear extinction during adolescence is reduced in both humans and mice.

    “fear extinction during adolescence is reduced in both humans and mice [26]”
  • Adolescents show attenuated fear extinction learning relative to children and adults, although all groups show similar acquisition of cued fear.

    “Although all groups showed similar acquisition of cued fear, the adolescents showed attenuated fear extinction learning relative to children and adults (Pattwell et al., 2012).”

  • Immunohistochemical evidence points to reduced synaptic plasticity in areas of the mPFC after extinction recall in adolescent rodents.

    “Immunohistochemical evidence points to reduced synaptic plasticity in areas of the mPFC after extinction recall in adolescent rodents7,10.”
  • Adolescents continue to show signs of defensive responding to previously learned threat cues, suggesting an age-specific relative dysregulation of the process that updates threat associations as safe.

    “For example, adolescents continue to show signs of defensive responding to previously learned threat cues (freezing in rodents and elevated skin conductance in humans), suggesting an age-specific relative dysregulation of the process that updates threat associations as safe7,10–13.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
