RESUMO

OBJECTIVES : We investigated the relationship between periventricular and deep white matter hyperintensity and cognitive function in Alzheimer's disease (AD) and mild cognitive impairment (MCI). METHODS : T2-weighted MRI scans were performed in 41 subjects with AD 38 subjects with mild cognitive impairment and 38 control subjects. Periventricular and deep white matter hyperintensities were rated on a Fazekas 0-3 scale by a medical specialist of the department of radiology blind to clinical diagnosis. Cognitive function was assessed by using Cognitive Assessment and Reference Diagnoses System. RESULTS : No significant differences between demographic characteristics and vascular risk factors were revealed comparing AD, MCI and controls. The frequencies of AD were significantly higher than those of MCI and normal control in Grade 2 and 3 of periventricular hyperintensity and Grade 3 of deep white matter hyperintensity. The scores of amnesia, executive function and attention were significantly lower in Grade 2 and 3 of periventricular hyperintensity than in Grade 0 and 1. The scores of attention were significantly lower in Grade 3 of deep white matter hyperintensity than in Grade 0, 1 and 2. CONCLUSION : Periventricualr hyperintensities are associated with cognitive decline in amnesia, executive function and attention, while deep white matter hyperintensities are associated with cognitive decline in attention.

RESUMO

Objectives : A diverse range of adverse effects has been linked to the application of antidepressants for the treatment of depressive disorder. Recently, evidence has been emerging of the adverse metabolic effects of antidepressants. This study investigated the effects of antidepressants on plasma glucose and other factors in the fat and muscle tissue relating to metabolism. METHODS : Long-Evans-Tokushima-Ostuka (LETO) rats were used to evaluate the effects of different antidepressants. Amitriptyline, fluoxetine, and mirtazapine were administered to each of three subgroups for 4 weeks, between 11 and 15 weeks old, while a fourth subgroup was administered no antidepressant during the same period. Changes of weight and daily intake were monitored. Tissues and blood were collected at 15 weeks. RESULTS : The fluoxetine subgroup showed lower weight gain and lower food efficacy ratio than did the other subgroups. Blood glucose and other circulating factors showed no significant differences among groups, except for the leptin levels of the fluoxetine subgroup. However, the amitriptyline and mirtazapine subgroups showed similar patterns in the response of mRNA expression of peroxisome proliferator-activated receptors gamma cofactor-1 and uncoupling protein-1, 2, 3. CONCLUSION : These results could indicate possible differences in metabolic response based on the kind of antidepressant used.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate the suicide ideation considering sociodemographic factor and degree of symptoms, subjective emotional state of the social phobia patients. METHODS: Study subjects consisted of 34 social phobia patients diagnosed with the criteria of DSM-IV. The authors evaluated the degree of symptomes, depression, hopelessness, disability. For the evaluation of suicide ideation, Beck Suicide Ideation Scale (SIS) was applied to the patients. Sociodemographic data and Clinical characterictics was analyzed by t test or Oneway ANOVA. We employed the correlation test for the evaluation of relationship between suicide ideation and self reported scale score. RESULTS: 1) Suicide ideation was higher in the young aged, unmarried patients, and past suicide attemptors. 2) In the correlation test, Suicide ideation was highly correlated with depression and hopelessness. 3) There were no significant correlations between suicide ideation and degree of symptomes. CONCLUSION: In this study. We concluded that the most powerful predictor of suicide ideation in social phobia is not the degree of symptomes itself but the depression and hopelessness.
