Neurobiological Alterations in Females With PTSD: A Systematic Review.

Area of Science:

• Neuroscience
• Psychiatry
• Medical Imaging

Background:

• Most females experience trauma, yet not all develop PTSD, indicating a need to understand risk factors.
• Previous research overlooked within-group differences among females, limiting understanding of PTSD development.
• This review focuses on neurobiological differences in females with and without PTSD.

Approach:

• Systematic review of 56 studies using magnetic resonance imaging (MRI) techniques.
• Included structural MRI (sMRI), functional MRI (fMRI), diffusion tensor imaging (DTI), and resting-state functional connectivity (rs-FC).
• Compared neurobiological findings between females diagnosed with PTSD and those without.

Key Points:

• Examined biopsychosocial factors influencing PTSD vulnerability in females.
• Discussed the impact of trauma timing and type on PTSD risk.
• Highlighted cognitive-behavioral mechanisms like rumination and fear extinction deficits.
• Described symptom patterns, comorbidities, and sex-specific treatment/parenting implications.

Conclusions:

• Identified critical areas for future research in female PTSD.
• Emphasized understanding developmental brain alterations and trauma impact.
• Called for research into neuroendocrine and socio-cultural factors in female PTSD neurobiology.
