Eye movement desensitization and reprocessing for depressed individuals with multiple sclerosis: A pilot study.

BACKGROUND: Multiple studies have highlighted elevated rates of depression among individuals with Multiple Sclerosis (MS), with its associated symptoms posing a significant threat to overall well-being. Moreover, existing literature suggests a potential interconnection between depressive manifestations and the decline of physical functionalities in the context of MS. OBJECTIVE: to examine the viability of the Eye Movement Desensitization Reprocessing (EMDR) therapy protocol for the treatment of depressive disorders (DeprEND) for alleviating depression in individuals with MS. METHODS: We conducted a process-outcome study to examine the feasibilty and effectiveness DeprEND enrolling 13 individuals with MS and depressive symtpoms. Psychological and physical assessment pre-, post-intervention and 3-month follow-up were included. Pre- and post-magnetic resonance imaging (MRI) scans were conducted to analyze potential alterations in brain function. RESULTS: The EMDR DeprEND treatment showed a high level of adherence and feasibility. Significant reductions in depressive symptoms were found at post-intervention and at 3 months follow-up. No significant differences were observed in terms of physical symptoms. A significant modulation observed in parietal and premotor areas when examining negative valence stimuli post-treatment was found. CONCLUSION: for The EMDR DeprEND protocol may represent a feasible and cost-effective treatment for reducing depressive symptoms in MS patients and improving their mental well-being.

Maturation of preterm newborn brains: a fMRI-DTI study of auditory processing of linguistic stimuli and white matter development.

To evaluate brain development longitudinally in premature infants without abnormalities as compared to healthy full-term newborns, we assessed fMRI brain activity patterns in response to linguistic stimuli and white matter structural development focusing on language-related fibres. A total sample of 29 preterm newborns and 26 at term control newborns underwent both fMRI and DTI. Griffiths test was performed at 6 months of corrected age to assess development. Auditory fMRI data were analysed in 17 preterm newborns at three time points [34, 41 and 44 weeks of post menstrual age (wPMA)] and in 15 controls, at term. Analysis showed a distinctive pattern of cortical activation in preterm newborns up to 29 wPMA moving from early prevalent left temporal and supramarginal area activation in the preterm period, to a bilateral temporal and frontoopercular activation in the at term equivalent period and to a more fine-grained left pattern of activity at 44 wPMA. At term controls showed instead greater bilateral posterior thalamic activation. The different pattern of brain activity associated to preterm newborns mirrors their white matter maturation delay in peripheral regions of the fibres and thalamo-cortical radiations in subcortical areas of both hemispheres, pointing to different transient thalamo-cortical development due to prematurity. Evidence for functional thalamic activation and more mature subcortical tracts, including thalamic radiations, may represent the substantial gap between preterm and at term infants. The transition between bilateral temporal activations at term age and leftward activations at 44 weeks of PMA is correlated to better neuropsychological results in Griffiths test.

Neural and genetic correlates of antidepressant response to sleep deprivation: a functional magnetic resonance imaging study of moral valence decision in bipolar depression.

CONTEXT: Total sleep deprivation combined with light therapy causes rapid amelioration of bipolar depression. A polymorphism in the promoter for the serotonin transporter influences both antidepressant response and the structure and function of specific brain areas. OBJECTIVE: To determine whether antidepressant therapy or the genotype of the serotonin transporter influence the pattern of neural response to a task targeting the depressive biases in information processing (moral valence decision). DESIGN: Before-and-after trial studying the biologic correlates of response to treatment. SETTING: University hospital. Patients Twenty inpatients with bipolar depression. Intervention Repeated total sleep deprivation combined with light therapy for 1 week. MAIN OUTCOME MEASURES: Brain blood oxygen level-dependent functional magnetic resonance imaging using a 3.0-T scanner before and after treatment. Self-ratings and observer ratings of mood (visual analog scale 3 times daily and Hamilton Depression Rating Scale) before and after treatment. RESULTS: We found significant interactions of treatment (before and after), response to treatment (Hamilton Depression Rating Scale score <8), and moral valence of the stimuli (positive or negative) in the anterior cingulate cortex, dorsolateral prefrontal cortex, insula, and parietal cortex. In these areas, responders changed their blood oxygen level-dependent responses to emotional stimuli in a pattern opposite of that in nonresponders. Genotype of the promoter for the serotonin transporter predicted response to treatment and influenced baseline neural responses in the anterior cingulate cortex and the dorsolateral prefrontal cortex. CONCLUSION: Multiple factors that affect or are affected at the individual level by major depressive episodes in the course of bipolar disorder significantly interact in influencing brain cortical activity in specific areas.
