John, 45, served as Navy Seal and was involved in multiple deployments. He experienced three near-drowning accidents and two motor vehicle accidents and was concerned about the extent of his brain damage. John had a variety of symptoms including: confusion, severe memory problems, cognitive decline, anxiety and fear of going to sleep.
His qSPECT findings revealed decreased blood flow in the frontal, temporal, parietal occipital and cerebellar lobes of the brain, which is consistent with the SPECT pattern for traumatic brain injury. The imaging also showed signs of toxic brain injury and increased blood flow in the basal ganglia, thalami and posterior cingulate gyrus, which have been associated with PTSD.
