Comparison of depressive indices: reliability, validity, relationship to anxiety and personality and the role of age and life events.

INTRODUCTION: Although a great number of depressive scales were developed during the last decades, there are only a few studies that compare them in terms of reliability and validity. The current study aimed to compare the properties of some of the most popular of these scales. MATERIALS AND METHODS: The study sample included 40 depressed patients 29.65+/-9.38 years old, and 120 normal comparison subjects 27.23+/-10.62 years old. The clinical diagnosis was reached by consensus of two examiners with the use of the SCAN v.2.0. The scales compared were the CES-D, ZDRS, BDI-I, and the KSQ. The STAI, the Life Change Scale (Holms and Rahe), and the EPQ were also administered. The analysis included the comparison of psychometric properties and the use of Pearson correlation coefficient and factor analysis. RESULTS: The results suggested that no scale was clearly superior to the others. All scales correlated to anxiety measurements, sociodemographic variables, personality dimensions and non-specific indices. The results reported here include an appendix with algorithms that help transforming one scale score into other scales scores. These algorithms can be useful for comparison purposes in meta-analytic studies. DISCUSSION: The comparison of several depressive scales provided no impressive results on the superiority or inferiority of a specific scale in comparison to the others.

Life events and clinical subtypes of major depression: a cross-sectional study.

The present study aimed to investigate the relationship between stressful life events and depression. Ninety major depressive patients, aged 36.57 +/- 12.02 years, and 121 matched controls, aged 27.11 +/- 10.59 years, took part in the study. The life change units (LCU) according to Rahe et al. were used for the quantification of life events. The results suggested that males reported significantly more life events than females. Atypical males differed from all other gender-by-type groups, while no other differences emerged. LCU correlated with melancholic indices but did not correlate with anxiety or functioning. The results suggest that subgroups of depressive patients are characterized by the presence of stressful life events. Male atypical patients reported the highest load of life events. The question that arises is whether this finding is valid or whether these patients (who have higher personality psychopathology and interpersonal rejection sensitivity) tend to over-report life events.

Bulimia nervosa in atypical depression: the mediating role of cyclothymic temperament.

OBJECTIVE: Recent data indicate significant clinical, biological, and treatment response overlap between eating and bipolar disorders, especially when soft symptoms of either spectrum disorders are considered. The aim of the present analyses is to evaluate the lifetime prevalence of bulimia nervosa (BN) in patients with atypical depression (AD) and to delineate any demographic, clinical, personality or temperamental factors that may characterize this subgroup. METHOD: We examined in a semi-structured format 107 consecutive patients who met DSM-IV criteria for major depressive episode with atypical features and we separated them into two groups according to the co-occurring criteria for BN. They were further evaluated on the basis of the Atypical Depression Diagnostic Scale (ADDS), the Hopkins Symptoms Check-list (HSCL 90), and the Hamilton Rating Scale for Depression (HRSD), coupled with its modified form for reverse vegetative features, as well as Axis I and II comorbidity and temperamental dispositions. RESULTS: Seventeen (17.8%) percent of AD met the DSM-IV criteria for Bulimia Nervosa (BN+). These patients, compared with those who did not meet criteria for BN (BN-), were indistinguishable on all demographic and most psychopathologic and clinical features (including bipolar I and II), but were significantly higher in lifetime comorbidity for Narcissistic, Histrionic, Borderline and Dependent personality disorders as well as that for Cyclothymic temperament. BN+ also scored higher on the ADDS items of reactivity of mood and interpersonal sensitivity. LIMITATIONS: Correlational clinical study in which doctors could not be entirely blind to the variables under investigation. CONCLUSIONS: Cyclothymic temperament and related mood reactivity and interpersonal sensitivity may account for much of the relationship between AD and BN. Narcissistic, histrionic and borderline traits, too, seem to be related to the presence of a cyclothymic disposition. The data overall, in particular the cyclothymic reactivity in the absence of differences in BP-I and II, all support the hypothesis that places BN in the "ultra-soft" bipolar realm.

Peripheral thyroid dysfunction in depression.

The involvement of the thyroid gland and thyroid hormones is generally believed to be important in the aetiopathogenesis of major depression. Major support comes from studies in which alterations in components of the hypothalamic-pituitary-thyroid (HPT) axis have been documented in patients with primary depression. However, screening thyroid tests are often routine and add little to the diagnostic evaluation. Overt thyroid disease is rare among depressed inpatients. The finding that depression often co-exists with autoimmune subclinical thyroiditis suggests that depression may cause alterations in the immune system, or that in fact it could be an autoimmune disorder itself. The outcome of treatment and the course of depression may be related to thyroid status as well. Augmentation of antidepressant therapy with the co-administration of thyroid hormones (mainly T3) is a well-documented treatment option for refractory depressed patients. Review of the literature suggests that there are no conclusive data on the role of thyroid function in depression. It is clear that depression is not characterised by an overt thyroid dysfunction, but it is also clear that a subgroup of depressed patients may manifest subtle thyroid abnormalities, or an activation of an autoimmune process. There is a strong possibility that the presence of a subtle thyroid dysfunction is a negative prognostic factor for depression and may demand specific therapeutic intervention.

Clinical psychoacoustics in Alzheimer's disease central auditory processing disorders and speech deterioration.

BACKGROUND: Difficulty in speech understanding in the presence of background noise or competing auditory signals is typically present in central auditory processing disorders. These disorders may be diagnosed in Alzheimer's disease as a result of degeneration in the central auditory system. In addition perception and processing of speech may be affected. MATERIAL AND METHODS: A MEDLINE research was conducted in order to answer the question whether there is a central auditory processing disorder involved in Alzheimer's disease. A second question to be investigated was what, if any is the connection, between central auditory processing disorders and speech deterioration?Articles were retrieved from the Medline to find relevance of Alzheimer's dis ease with central auditory processing disorders, they summed up to 34. Twelve papers were studied that contained testing for CAPD through psychoacoustic investigation. An additional search using the keywords 'speech production' and 'AD' produced a result of 33 articles, of them 14 are thoroughly discussed in this review as they have references concerning CAPD. The rest do not contain any relavent information on the central auditory system. RESULTS: Psychoacoustic tests reveal significantly lower scores in patients with Alzheimer's disease compared with normal subjects. Tests concerning sound localization and perception of tones as well as phoneme discrimination and tonal memory reveal deficits in Alzheimer's disease. Central auditory processing disorders may exist several years before the onset of clinical diagnosis of Alzheimer's disease. Segmental characteristics of speech are normal. Deficits exist concerning the supra-segmental components of speech. CONCLUSIONS: Central auditory processing disorders have been found in many cases when patients with Alzheimer's disease are tested. They may present as an early manifestation of Alzheimer's disease, preceding the disease by a minimum of 5 and a maximum of 10 years. During these years changes in the central auditory system, starting in the temporal lobe, may produce deficits in speech processing and production as hearing and speech are highly connected human functions. Another theory may be that spread of degeneration of the central nervous system has as a consequence, speech deterioration. Further research and central auditory processing disorders testing in the elderly population are needed to validate one theory over the other.

Unipolar late-onset depression: A comprehensive review.

BACKGROUND: The older population increases all over the world and so also does the number of older psychiatric patients, which manifest certain specific and unique characteristics. The aim of this article is to provide a comprehensive review of the international literature on unipolar depression with onset at old age. METHODS: The authors reviewed several pages and books relevent to the subject but did not search the entire literature because of it's overwhelming size. They chose to review those considered most significant. RESULTS: The prevalence of major depression is estimated to be 2% in the general population over 65 years of age. The clinical picture of geriatric depression differs in many aspects from depression in younger patients. It is not yet clear whether it also varies across cultures and different socio-economic backgrounds. Biological data suggest that it is associated with an increased severity of subcortical vascular disease and greater impairment of cognitive performance. Many authors consider the existence of a somatic disorder to be related to the presence of depression in late life, even constituting a negative prognostic factor for the outcome of depression. Most studies support the opinion that geriatric depression carries a poorer prognosis than depression in younger patients. The therapeutic intervention includes pharmacotherapy, mainly with antidepressants, which is of established value and psychotherapy which is not equally validated. CONCLUSION: A significant number of questions regarding the assessment and treatment of geriatric depression remain unanswered, empirical data are limited, and further research is necessary.
