Evolution of neuropsychological profile in motor subtypes of multiple system atrophy

IntroductionCognitive deficits and neuropsychiatric symptoms occur in parkinsonian and cerebellar subtypes of Multiple System Atrophy (MSA-P and MSA-C). These symptoms have been investigated mainly in cross-sectional studies. The present 1-year follow-up study aimed at evaluating the evolution of cognitive and neuropsychiatric profile in patients with MSA-C and MSA-P.MethodsTwenty-nine patients with MSA-P, 21 with MSA-C and 30 healthy subjects (HCs) underwent a neuropsychological battery and questionnaires assessing depression and apathy (T0). After 1 year (T1), patients with MSA-C and MSA-P underwent the same neuropsychological and neuropsychiatric tools employed at T0.ResultsAt T0, MSA-P and MSA-C groups were more depressed and apathetic and performed worse on tests assessing repetition abilities, executive and attentive functions than HCs. MSA-P and MSA-C groups did not differ on cognitive variables and neuropsychiatric scales. At T1, a significant worsening in spatial planning and psychomotor speed in MSA-C group and a significant worsening in memory, spatial planning, repetition abilities and functional autonomy in MSA-P group were found. The prevalence of apathy increased in both subtypes, whereas the prevalence of depression was reduced in MSA-C and relatively consistent in MSA-P.ConclusionsThe finding revealed a wide-ranging worsening of cognitive functions in MSA-P and a significant decline in processing speed in MSA-C. These results underline the relevance of evaluating cognitive and psychiatric features of MSA over the course of the disease in the daily clinical practice.

Self-reported outcomes of a randomized trial comparing three community health worker interventions for diabetes prevention among Cambodian Americans with depression

ObjectiveCambodian Americans have complex, interrelated and persistent medical and mental health problems stemming from genocide and the social determinants of health. We examined changes in multiple domains of self-reported health outcomes from a diabetes prevention trial. Methods: Cambodian Americans with depression and high risk for diabetes (n = 188) were randomized to one of three community health worker interventions: lifestyle vs lifestyle plus medication therapy management vs social services. Assessments were at baseline, 12- and 15-months. Results: The typical participant was 55 years old, female, earned below $20,000 annually, and had 7 years of education. About one-third were taking antidepressant medication and over half had elevated depressive symptoms. Relative to social services, lifestyle and lifestyle plus medication therapy management were both similarly effective at increasing diabetes knowledge, nutrition habits, sleep quality and decreasing pain; 2) lifestyle alone was superior to social services for self-reported health; and, 3) all three groups showed improved anxiety and insomnia. There were no effects on physical activity or physical functioning. Conclusion: Community health worker interventions have multiple benefits beyond delaying diabetes. Practice Implications: Health promotion programs that are designed and delivered appropriately can impact even hard to reach and hard to treat groups.

Association between oophorectomy and depression in patients with comorbidities: A nationwide cohort study in Taiwan

ObjectiveThis study investigated the long-term rates of depression after oophorectomy for benign gynecological conditions with or without comorbidities.Materials and methodsThis retrospective cohort study examined data from the National Health Insurance Research Database (NHIRD) involving 8199 women aged ≥20 years who underwent unilateral or bilateral oophorectomy for benign gynecological conditions (cases) between 2000 and 2013 (index date). A second cohort consisted of 32,796 women who did not undergo oophorectomy (controls) who were matched 4:1 to cases by age and index year. The follow-up time was more than 10 years. For all participants, the analysis accounted for comorbidities including hypertension, diabetes mellitus, hyperlipidemia, stroke, chronic obstructive pulmonary disease (COPD), chronic liver disease and cirrhosis, chronic kidney disease, and anxiety. Crude hazard ratios, adjusted hazard ratios, and 95% confidence intervals (CIs) were calculated according to multivariable Cox proportional hazard regression models adjusting for age, comorbidity, and the combination of oophorectomy with one comorbidity.ResultsOur results show that unilateral or bilateral oophorectomy, whether performed by laparotomy or laparoscopy, increases the overall risk of depression (aHR: 1.36, 95%CI: 1.19–1.55). Compared with controls, women aged <50 years had a significantly higher incidence of depression. Having diabetes (aHR: 1.66, 95%CI: 1.09–2.51), hypertension (aHR:1.56, 95%CI:1.14–2.14), hyperlipidemia (aHR: 1.46, 95%CI: 1.04–2.05), stroke (aHR: 1.91, 95%CI: 1.01–3.60), COPD (aHR: 2.06, 95%CI: 1.3–3.26), chronic liver cirrhosis (aHR: 1.99, 95%CI:1.52–2.61), or anxiety (aHR: 5.01, 95%CI: 3.74–6.70) increased higher risk of depression compared with not having these comorbidities after oophorectomy. The likelihood of depression was highest within the first 6 years following oophorectomy (3–5years:aHR:1.26, 95%CI:1.00–1.58).ConclusionsOopherectomy increases the overall risk of depression. We offer useful information for surgical decision-making and preoperative assessments of women undergoing oophorectomy. It is concluded that a synergistic effect exists between oophorectomy and the comorbidities. Post-surgery, physicians should carefully evaluate the risk of depression developing amongst women with comorbidities. A postoperative follow-up time of at least 6 years is recommended, as this period was associated with a significantly higher rate of depression during our over 10-year follow-up.     

Effect of lacosamide on ethanol induced conditioned place preference and withdrawal associated behavior in mice: Possible contribution of hippocampal CRMP-2

BackgroundExcessive consumption of ethanol is known to activate the mTORC1 pathway and to enhance the Collapsin Response Mediator Protein-2 (CRMP-2) levels in the limbic region of brain. The latter helps in forming microtubule assembly that is linked to drug taking or addiction-like behavior in rodents. Therefore, in this study, we investigated the effect of lacosamide, an antiepileptic drug and a known CRMP-2 inhibitor, which binds to CRMP-2 and inhibits the formation of microtubule assembly, on ethanol-induced conditioned place preference (CPP) in mice.MethodsThe behavior of mice following ethanol addiction and withdrawal was assessed by performing different behavioral paradigms. Mice underwent ethanol-induced CPP training with alternate dose of ethanol (2 g/kg, po) and saline (10 ml/kg, po). The effect of lacosamide on the expression of ethanol-induced CPP and on ethanol withdrawal associated anxiety and depression-like behavior was evaluated. The effect of drug on locomotor activity was also assessed and hippocampal CRMP-2 levels were measured.ResultsEthanol-induced CPP was associated with enhanced CRMP-2 levels in the hippocampus. Lacosamide significantly reduced the expression of ethanol-induced CPP and alleviated the levels of hippocampal CRMP-2 but aggravated withdrawal-associated anxiety and depression in mice.ConclusionThe present study demonstrated the beneficial effect of lacosamide in attenuation of expression of ethanol induced conditioned place preference via reduction of hippocampal CRMP-2 level. These findings suggest that lacosamide may be investigated further for ethanol addiction but not for managing withdrawal.     

Mise à jour des croyances et congruence à l'humeur dans le trouble dépressif

Depressive disorder is characterized by a polymorphic symptomatology associating emotional, cognitive and behavioral disturbances. One of the most specific symptoms is negative beliefs, called congruent to mood. Despite the importance of these beliefs in the development, the maintenance, and the recurrence of depressive episodes, little is known about the processes underlying the generation of depressive beliefs. In this paper, we detail the link between belief updating mechanisms and the genesis of depressive beliefs. We show how depression alters information processing, generating cognitive immunization when processing positive information, affective updating bias related to the valence of belief and prediction error, and difficultie to disengage from negative information. We suggest that disruption of belief-updating mechanisms forms the basis of belief-mood congruence in depression.
