Summary
This case report details a war veteran with posttraumatic stress disorder (PTSD). Treatment with psychotherapy led to symptom improvement and normalized brain SPECT imaging results.
Area of Science:
- Neuroscience
- Psychiatry
- Psychology
Background:
- Posttraumatic stress disorder (PTSD) is a debilitating condition often associated with trauma exposure.
- War veterans are a population at high risk for developing PTSD, presenting with complex symptoms.
Observation:
- A 36-year-old Croatian war veteran presented with impulse control issues, aggression, interpersonal conflict, and nightmares.
- Diagnosed with PTSD (MKB-10 criteria), the patient underwent comprehensive psychiatric, psychological, and neurological evaluations.
- Brain SPECT imaging revealed unilateral hyperperfusion in the dominant hemisphere, specifically in the amygdala/nucleus accumbens region, while medication-free.
Findings:
- Repetitive brain SPECT scans confirmed significant unilateral increase in regional cerebral blood flow (rCBF) in the amygdala/nucleus accumbens projection area.
- Following a year of intensive group psychotherapy focused on interpersonal and social relations, the patient experienced diminished PTSD symptoms.
- Post-treatment SPECT imaging demonstrated normalization of rCBF, with no significant interhemispheric differences observed.
Implications:
- This case highlights the potential utility of brain SPECT imaging in assessing neurobiological correlates of PTSD.
- Psychotherapy can effectively alleviate PTSD symptoms and lead to measurable changes in brain activity.
- The findings suggest a link between amygdala/nucleus accumbens activity and PTSD symptom severity, which may be modulated by therapeutic interventions.
