Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) share memory-related dysfunctions. Treating them as memory disorders using novel memory reprocessing techniques shows promise for effective treatment.
Area of Science:
- Neuroscience
- Psychiatry
- Memory Research
Background:
- Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) are distinct conditions with high comorbidity.
- Both disorders may stem from shared physiological dysfunctions and exhibit similar characteristics.
Purpose of the Study:
- To review evidence suggesting PTSD and SUD are disorders of memory.
- To explore novel therapeutic strategies targeting pathological memory reprocessing.
Main Methods:
- Review of existing literature on PTSD, SUD, and memory consolidation/reconsolidation.
- Examination of therapeutic interventions like extinction therapy, reconsolidation blockade, state dependency, and emotional remodeling.
Main Results:
- PTSD and SUD share characteristics and may arise from common memory-related physiological dysfunctions.
- Reactivation-dependent memory malleability offers new therapeutic avenues.
- Innovative treatments like state dependency and emotional remodeling show encouraging results.
Conclusions:
- Viewing PTSD and SUD as memory disorders, specifically related to hyperreactivity to reminders, provides a unified therapeutic perspective.
- Targeting pathological memory reprocessing through novel techniques offers promising treatment strategies for both PTSD and SUD.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
