Cross-cultural evaluation of the French version of the LEIPAD, a health-related quality of life instrument for use in the elderly living at home.

PURPOSE: To cross-culturally adapt a French version of the LEIPAD, a self-administered questionnaire assessing the health-related quality of life (HRQoL) in adults aged 65 years and over living at home, and to evaluate its psychometric properties. METHODS: After having translated LEIPAD in accordance with guidelines, we studied psychometric properties: reliability and construct validity-factor analysis, relationships between items and scales, internal consistency, concurrent validity with the Medical Outcome Study Short-Form 36 and known-groups validity. RESULTS: The results obtained in a sample of 195 elderly from the general population showed very good acceptability, with response rates superior to 93 %. Exploratory factor analysis extracted eight factors providing a multidimensionality structure with five misclassifications of items in the seven theoretical scales. Good internal consistency (Cronbach's alpha ranging from 0.73 and 0.86) and strong test-retest reliability (ICCs higher than 0.80 for six scales and 0.70 for one) were demonstrated. Concurrent validity with the SF-36 showed small to strong expected correlations. CONCLUSION: This first evaluation of the French version of LEIPAD's psychometric properties provides evidence in construct validity and reliability. It would allow HRQoL assessment in clinical and common practice, and investigators would be able to take part in national and international research projects.

[Therapeutic efficacy and safety of repetitive Transcranial Magnetic Stimulation in depressions of the elderly: a review]. / Efficacité et tolérance de la stimulation magnétique transcrânienne (SMTr) dans le traitement des dépressions chez le sujet âgé: revue de la littérature.

INTRODUCTION: During the past 15 years, therapeutic effects of repetitive Transcranial Magnetic Stimulation (rTMS) have been studied in psychiatric diseases, particularly in the treatment of depressive disorders. There are more and more data suggesting its efficacy in the treatment of depression in older patients. Thus, the authors found it useful to conduct an up-to-date review of studies that examined the efficacy and safety of rTMS to treat depressive disorders in the aged. METHOD: After an exhaustive consultation of databases (Medline/PubMed and the Avery-George-Holtzheimer Database of rTMS Depression Studies), supplemented by a manual research, the authors retained studies evaluating the therapeutic efficacy of rTMS on depressive disorders in the aged. RESULTS: Fifteen studies were retained. Four open studies using high frequency rTMS, applied to the left dorsolateral prefrontal cortex (DLPFC), demonstrated a decrease in the mean Hamilton Depression Rating Scale (HDRS) scores; however, only a quarter of the aged patients studied experienced a significant remission of depression. Five parallel arm double-blind versus placebo studies concluded in contradicting results: two studies confirmed a significantly greater efficacy of rTMS compared to placebo, whereas three studies did not; but the sham procedure (positioning coil at 90 degrees from the scalp) was disputable in most studies. One study concluded in therapeutic efficacy by inhibiting the right DLPFC. Three controlled parallel arm studies compared rTMS and electroconvulsive-therapy (ECT); one study concluded in greater efficacy of ECT at end of treatment, but the number of ECT treatments depended on the patients' response, whereas a 15-day course of rTMS was systematically administered; additionally HDRS scores were similar in two groups of patients (rTMS and ECT) at 6 months. Lastly, three studies focused on aged patients with cerebrovascular disease. They showed the efficacy of rTMS, although older age and smaller frontal gray mater volumes were associated with a poorer response to rTMS. DISCUSSION: Thus, although some studies concluded contradicting results, literature data globally sustain an efficacy of rTMS for depression in the elderly. Several parameters might be associated with greater antidepressant efficacy (higher intensity pulses of rTMS of the left DLPFC; higher number of stimulations or higher number of rTMS sessions). Poorer responsiveness to rTMS may be related to several patients' factors including older age and smaller frontal gray matter volumes; lesions of the white matter pathways connecting the left DLPFC and the left anterior cingulate cortex might explain a poor response to rTMS. Literature data globally confirm that rTMS is safe and does not produce cognitive deficits, even among highly vulnerable patients with clinical evidence of cerebrovascular disease. CONCLUSION: Many questions remain concerning the optimal stimulation parameters, administration protocol, and privileged indications. Thus, the next rTMS studies should be carefully designed to clarify these questions.

[Recurrences of bipolar disorders - comparative study of bipolar disorders, recurring depressions and single depressions in a cohort of patients aged over 65 years]. / Récurrences dans les troubles bipolaires - Etude comparative à partir d'une population âgée de 65 ans et plus entre troubles bipolaires, troubles dépressifs récurrents et épisodes dépressifs simples.

BACKGROUND: Bipolar mood disorders, after starting at adulthood, may remain active throughout life, but bipolar disorders may only be revealed in later life. Indeed, Yet few data on bipolar disorders in the elderly have been reported in the litterature. The influence of normal aging on the outcome of the disease as well as the specific prognosis of bipolar disorders in the elderly has occasionally been studied. Eventually Finally, and contrasting with adults, few studies comparing the various subtypes of mood disorders were have been performed in the elderly. OBJECTIVES: We therefore developed a study in patients aged 65 or above, in order to evaluate the course (recurrences) of bipolar disorders, compared to recurring depressions and single depressions, and to determine the influence of recurrences on the outcome of bipolar disorders. METHOD: Patients aged over 65 years were inpatients admitted to the department of psychiatry in 2000 for one of the three previously mentioned diagnoses according to DSM IV. Retrospective data were collected from medical reports. Prospectively, data were collected from the general practitioner of each patient (relying on telephone calls), before statistical analysis was performed. RESULTS: Our study demonstrates a more severe outcome for bipolar disorders compared to recurring depressions and single depressions. Patients with bipolar disorders have a higher prevalence of psychiatric recurrences. Furthermore, the greater the number of previous relapses (or the longer the duration and intensity of the disease), the higher the risk of future new future recurrences both in bipolar disorders and recurring depressions. An age of onset of bipolar disorders before 60 years and more than 5 in-hospital admissions increase the risk of recurrences. CONCLUSION: We originally compare the outcome of bipolar disorders in the elderly, to recurring depressions and single depressions. We confirm the fatal outcome of recurrences in bipolar disorders in old age. Bipolar disorders in the elderly should be considered as a real public health care problem: strategies to minimize the number of episodes experienced by patients with bipolar illness must be pursued aggressively throughout life.
