[Ti] Título:Diffusion tensor imaging change in crus cerebri in striatocapsular infarction and correlation with upper extremity motor dysfunction.

[Ab] Resumo:PURPOSE: There is limited information about the secondary changes in the pyramidal tract after some specific types of deep brain infarction including striatocapsular infarction. The aims of the current study were to investigate diffusion changes in the crus cerebri in patients with striatocapsular infarction using diffusion tensor imaging (DTI), and analyze the relationship between such changes and upper extremity motor dysfunction. MATERIALS AND METHODS: Fifteen patients with acute onset of striatocapsular infarction and unilateral upper extremity motor dysfunction for the first time were studied prospectively. DTI was performed 2 weeks after disease onset, fractional anisotropy and mean diffusivity values of the bilateral crus cerebri were measured, the asymmetry indices of bilateral fractional anisotropy were calculated, and the relationship between the asymmetry index value and the Fugl-Meyer assessment score for the affected upper extremity function was evaluated. RESULTS: Two weeks after disease onset, the fractional anisotropy value of the affected crus cerebri was reduced significantly compared with that of the unaffected crus cerebri (0.69 vs. 0.77; p < 0.001); there was no significant difference between bilateral mean diffusivity values. After correction for infarct size (448.93 ± 227.67 mm(2)) there was a negative correlation between the asymmetry index value and the Fugl-Meyer assessment score of the affected upper extremity (r = -0.78, p = 0.001). CONCLUSIONS: DTI can detect the diffusion change in the crus cerebri in patients with striatocapsular infarction during the early stage of the disease and the integrity of the pyramidal tract in the crus cerebri is closely related to the motor function of the affected upper extremity.

[Ti] Título:Increased cerebellar-default-mode-network connectivity in drug-naive major depressive disorder at rest.

[Ab] Resumo:The default-mode network (DMN) has been implicated in the neurobiology of major depressive disorder (MDD), and the cerebellum is suggested to be involved in high-order cognitive network such as the DMN. However, the specific contribution of the cerebellum to the DMN alterations remains equivocal. This study was conducted to examine the cerebellar-DMN connectivity in drug-naive MDD directly by using the cerebellum Crus I as seeds.Forty-four drug-naive MDD patients and 44 healthy controls participated in the resting-state scan. Functional connectivity (FC) was applied to analyze the images.Significantly increased FCs were observed between the right Crus I and the right inferior frontal cortex (orbital part)/superior temporal pole, bilateral MPFC (orbital part), and left middle temporal gyrus in the patients compared with the controls. There was a significantly positive correlation between the z values of the right Crus I-bilateral MPFC (orbital part) connectivity and the scores of Automatic Thoughts Questionnaire in the patients (r = 0.329, P = 0.029).The findings reveal that depressed patients have increased cerebellar-DMN connectivity with clinical significance, and thus highlight the contribution of the cerebellum to the DMN alterations in neurobiology of MDD.

[Ti] Título:An analysis of cerebral blood flow from middle cerebral arteries during cognitive tasks via functional transcranial Doppler recordings.

[Ab] Resumo:Functional transcranial Doppler (fTCD) is a useful medical imaging technique to monitor cerebral blood flow velocity (CBFV) in major cerebral arteries. In this paper, CBFV changes in the right and left middle cerebral arteries (MCA) caused by cognitive tasks, such as word generation tasks and mental rotation tasks, were examined using fTCD. CBFV recordings were collected from 20 healthy subjects (10 females, 10 males). We obtained both the raw CBFV signal and the envelope CBFV signal, which is the maximal velocity to gain more information about the changes and hemisphere lateralization in cognitive tasks compared to the resting state. Time, frequency, time-frequency, and information-theoretic features were calculated and compared. Sex effects were also taken into consideration. The results of our analysis demonstrated that the raw CBFV signal contained more descriptive information than the envelope signals. Furthermore, both types of cognitive tasks produced higher values in most signal features. Geometric tasks were more distinguished from the rest-state than verbal tasks and the lateralization was exhibited in right MCA during geometric tasks. Our results show that the raw CBFV signals provided valuable information when studying the effects of cognitive tasks and lateralization in the MCA.
