汶川地震后慢性創(chuàng)傷后應(yīng)激障礙神經(jīng)通路腦影像研究
[Abstract]:BACKGROUND: According to the three theoretical systems of the theory, the cognitive theory, the social-personal theory, and the treatment methods derived from these three theories, this paper explores the neural pathways of these theories and methods. Four chronic post-traumatic stress disorder neurological pathways were suggested, one is the fear pathway: the thalamus-pituitary-medial prefrontal lobe-hippocampus pathway, including the cerebellum, the middle seam nucleus, the blue spot, the ventral side of the midbrain, and so on. Two is reward path: there is a V-septal nucleus-ventral belly side is covered by the cover area-occipital-orbital. Three is the whole cognitive emotional attention, the way to improve the self-consciousness: the thalamus-parietal lobe-parietal lobe boundary zone-posterior buckle band-wedge blade-island leaf-back lateral frontal lobe pathway. Four is the choice of decision-making, the path of working memory: the anterior frontal lobe of the thalamus-dorsal frontal lobe, the anterior frontal lobe, and the back-dentate nucleus of the anterior buckle. Objective: To study the functional status of nerve pathway in post-traumatic stress disorder, and to provide a reasonable treatment method. Rationale. Methods: Study subjects are post-traumatic stress disorder patients Group and control group. Patients with post-traumatic stress disorder after Wenchuan earthquake (9-16 months) (126 of total) 28 cases). The control group was survivors of any disease without any disease after undergoing the same disaster in the same area (121 of the total samples) The whole brain connection, interest area research and exploration of resting state data using SPM8 software were studied in 24 cases. Correlation between brain regions. Using FSL software to study the traumatic visual stimuli of visual adolescents and adults, adult human auditory traumatic stimulation of brain BOLD Signal enhancement or attenuation. Results: The study of all-brain-connection method of resting state data shows that 7 is a weak positive connection after a type of error detection. and 2 is a relatively strong negative connection. The positive connection connection of the seven strips is the connection between the medial prefrontal lobe of the left side and the right side of the right side, the left hippocampus, the right hippocampus, the left hippocampus, the side of the right hippocampus and the right straight back, respectively Left rear buckle belt and left island The connection between the leaves and the right island leaves was determined by the corrected PO. 05Z2. 3. Under the negative traumatic visual stimuli, it was found that adolescents and adults were in a resting state, and the BOLD signal reduction area was at the above-mentioned level. Compared with control group, BOLD signal reduction area in the post-traumatic stress disorder group was higher than that of the control group on the right side island leaf and the right side region, mainly in the middle line structure and the right side brain region. In comparison with the group that subtracted negative visual tasks, the adolescents in the post-traumatic stress disorder group activated the increased area to the right side of the dorsal prefrontal lobe in the post-traumatic stress disorder group, with the reduced area being the right-side island leaf cortex, the right lateral cortex, the right buckle belt cortex, and the attachment There are a large number of white matter between these brain regions; in adults with negative traumatic auditory tasks, the group comparisons show that post-traumatic stress disorder groups are located on the right island leaf cortex, the right island leaf white matter, the right lateral cortex, and the right side. BOLD signal enhancement in white matter is higher than that of control group. The study shows that in resting condition, the study shows that the abnormality of the two pathways, the fear pathway centered on the medial prefrontal lobe, the attention self-consciousness pathway of the island leaf-posterior buckle band, and the suggestion are taken. The treatment and exposure treatment of attention was combined. In the case of visual wound stimulation, the four pathways of the post-traumatic stress disorder group were abnormal in adults and adolescents, whereas the right brain pathways had rehabilitation functions; and the results support four theories It is suggested that comprehensive treatment or intervention should be adopted. The right dorsal lateral frontal cortex and right posterior frontal cortex of adolescents with post-traumatic stress disorder are the most brittle in abnormal neural pathways. The weak brain regions suggest targeted cognitive therapy. The island leaves of post-traumatic stress disorder and the low functioning of the whole button support self-regulated attention pathway theory. It is suggested to adopt a treatment mode aiming at adjusting attention. The negative individualized hearing task is based on the realistic imagination therapy in the treatment of post-traumatic stress disorder in adults.
