Early and late onset depression in old age: different aetiologies, same phenomenology

BACKGROUND Phenomenological differences between older patients with early onset (EO; onset of first major depressive episode before 60 years) and late onset (LO) depression have been inconsistent but, if real, may reflect differences in aetiology. We aimed to compare aetiological factors, phenomenology and cognitive function in older patients with depression by age of onset. METHODS Subjects were all patients > or =60 years old (n=73) from 407 consecutive attenders to a Mood Disorders Unit, diagnosed with DSM-III-R Major Depressive Episode, at or close to the nadir of their episode. Putative risk factors were assessed by structured interview. Psychological morbidity and depressive symptoms were assessed by the 21-item Hamilton Rating Scale for Depression, CORE rating of psychomotor disturbance, Newcastle Endogeneity Scale, Zung Depression Scale and General Health Questionnaire. Cognition was assessed by tests of memory, attention, executive function and motor speed. RESULTS Personality abnormalities, a family history of psychiatric illness and dysfunctional past maternal relationships were significantly more common in EO depression. The two age of onset groups were essentially similar in terms of depressive sub-type and severity, phenomenology, history of previous episode, and in neuropsychological performance. LIMITATIONS Use of self-report data, moderate sample size, sample not age-matched, tertiary referral patients. CONCLUSIONS EO and LO depression are similar phenotypically, but differ aetiologically. The pursuit of mechanisms which predispose depressive episodes may be heuristically more valuable than further investigation of individual depressive features in distinguishing early from late onset depression.

Diagnosis of endometriosis by detection of nerve fibres in an endometrial biopsy: a double blind study

BACKGROUND Diagnosis of endometriosis currently requires a laparoscopy and this need probably contributes to the considerable average delay in diagnosis. We have reported the presence of nerve fibres in the functional layer of endometrium in women with endometriosis, which could be used as a diagnostic test. Our aim was to assess efficacy of nerve fibre detection in endometrial biopsy for making a diagnosis of endometriosis in a double-blind comparison with expert diagnostic laparoscopy. METHODS Endometrial biopsies, with immunohistochemical nerve fibre detection using protein gene product 9.5 as marker, taken from 99 consecutive women presenting with pelvic pain and/or infertility undergoing diagnostic laparoscopy by experienced gynaecologic laparoscopists, were compared with surgical diagnosis. RESULTS In women with laparoscopic diagnosis of endometriosis (n = 64) the mean nerve fibre density in the functional layer of the endometrial biopsy was 2.7 nerve fibres per mm(2) (+/-3.5 SD). Only one woman with endometriosis had no detectable nerve fibres. Six women had endometrial nerve fibres but no active endometriosis seen at laparoscopy. The specificity and sensitivity were 83 and 98%, respectively, positive predictive value was 91% and negative predictive value was 96%. Nerve fibre density did not differ between different menstrual cycle phases. Women with endometriosis and pain symptoms had significantly higher nerve fibre density in comparison with women with infertility but no pain (2.3 and 0.8 nerve fibre per mm(2), respectively, P = 0.005). CONCLUSIONS Endometrial biopsy, with detection of nerve fibres, provided a reliability of diagnosis of endometriosis which is close to the accuracy of laparoscopic assessment by experienced gynaecological laparoscopists. This study was registered with the Australian Clinical Trials Registry (ACTR) 00082242 (registered: 12/12/2007). The study was approved by the Ethics Review Committee (RPAH Zone) of the Sydney South West Area Health Service (Protocol number X05-0345) and The University of Sydney Human Research Ethics Committee (Ref. No. 10761) and all women gave their informed consent for participation.

Younger people with dementia : Diagnostic issues, effects on carers and use of services

Objective. To determine difficulties experienced by carers of younger people with dementia.

Quality of Life: Eating Disorders

Objective: There is a lack of measurements with predictive validity that are specific for quality of life (QOL) in patients with eating disorders. Method: A total of 306 eating disorder patients treated as inpatients completed the Quality of Life for Eating Disorders (QOL ED): 109 at both admission and discharge from hospital, 65 at both admission and after 12months. Patients also completed well-validated measures of eating disorders, psychological dysfunction and general physical and mental QOL. QOL ED consists of 20 self-report questions that provide scores for the domains of behaviour, eating disorder feelings, psychological feelings, effects on daily life, effects on acute medical status and body weight, and a global score. Results: QOL ED domain scores correlated appropriately with previously validated wellknown measures of eating disorders, psychological dysfunction, general QOL and behaviour and body weight (p < 0.001). The QOL ED shows high reliability (Cronbachs alpha=0.93). All scores changed significantly and appropriately during inpatient hospital treatment and between admission and 12 months after discharge from hospital (p < 0.001). The scores differed for anorexia nervosa, bulimia, eating disorder not specified (EDNOS) and no diagnosis. All no diagnosis (recovered) domain and global scores were significantly different from all diagnoses scores (p < 0.001). Conclusion: This quick, simple instrument fulfils all potential uses for QOL assessments in the clinical and research settings associated with eating disorders, including outcome.

Psychological morbidity in caregivers is associated with depression in patients with dementia

Summary:The relationship between psychological morbidity in caregivers and depression in patients with dementia was examined using data collected on 193 patient-care - giver dyads attending a memory disorders clinic. Caregivers had high rates and levels of psychological morbidity which were associated with the severity of dementia (but neither the type nor duration), with the caregiver being a spouse and female and living with the person with dementia. A logistic regression analysis identified clinician-rated patient depression score and demanding problem behaviors as being independently and significantly associated with caregiver psychological morbidity. This new finding of a link between patient depression and caregiver psychological morbidity has implications for more focused treatment programs for both caregivers and patients.

A 25-year longitudinal, comparison study of the outcome of depression.

BACKGROUND There is still a relative paucity of information about the long-term course of depression. METHODS Consecutive patients admitted to a teaching hospital psychiatry unit with symptoms of depression, previously assessed at 6 months and 2, 5 and 15 years after index admission, were reviewed at 25 years (N = 49, including eight informants of deceased probands, of an original 145 with major depression (DEPs)). Prospective psychiatric (N = 22) and retrospective surgical (N = 50) control groups assessed after 25 years were used for comparison. RESULTS A further decade of follow-up confirmed the chronicity of depression. Of depressed patients (DEPs) followed for the full 25-year-period only 12% of the 49 original DEPs recovered and remained continuously well, 84% experienced recurrences, 2% experienced an unremitting course and another 2% died by suicide. Note that in the first 15-year-period 6% (9/145 DEPs) committed suicide, a further 38 died and 32 were lost to follow-up. They experienced an average of three episodes of depression over the 25 years. In the decade since the 15-year follow-up, 27% improved in clinical outcome (including four of five previously chronically depressed patients), 55% remained unchanged and 18% worsened; and the number of episodes per year declined. Patients initially diagnosed with neurotic or endogenous depression had similar long-term outcomes. The criteria for a current DSM-III-R disorder were met by 37% of DEPs, including 11% with depression or dysthymia. On the global assessment of functioning scale 78% of the DEPs had some impairment compared to 62% of psychiatric controls and 40% of surgical controls. CONCLUSION Even after 25 years, severe depressive disorders appear to have poor long-term outcomes. Patients with chronic outcomes over 15 years can improve when followed over longer periods.

Staff outcomes from the Caring for Aged Dementia Care REsident Study (CADRES): A cluster randomised trial

BACKGROUND Dementia care mapping and person centred care are well-accepted as processes for improving care and well-being for persons with dementia living in the residential setting. However, the impact of dementia care mapping and person centred care on staff has not been well researched. OBJECTIVES The impact of person centred care and dementia care mapping compared to each other and to usual dementia care on staff outcomes was examined in terms of staff burnout, general well-being, attitudes and reactions towards resident behavioural disturbances, perceived managerial support, and quality of care interactions. DESIGN A cluster-randomised, controlled trial. SETTINGS The study was conducted between 2005 and 2007 in 15 residential aged care sites in the Sydney metropolitan area, Australia, with comparable management structures, staffing mix and ratios, and standards of care. PARTICIPANTS 194 consenting managers, nurses, therapists and nurse assistants working in the participating sites. METHODS Intervention care sites received training and support in either person centred care (n=5) or dementia care mapping (n=5); control sites continued with usual dementia care (n=5). Staff outcomes of those three groups were assessed before, directly after the four month intervention (post) and after a further four months (follow-up). The primary outcome measures were the Maslach Burnout Inventory-Human Services Survey and the 12-item General Health Questionnaire. Analysis involved repeated measures analyses of variance for each of the outcome measures and adjustment for potential confounders to limit bias. RESULTS The Maslach Burnout Inventory-Human Services Survey results showed that change over time in emotional exhaustion scores differed between the three groups. Post-hoc analyses for each group separately revealed that the only significant time effect was in the dementia care mapping group (p=0.006), with emotional exhaustion scores declining over time. At baseline, more perceived support from management was associated with less emotional exhaustion (r(s)=0.26, p=0.004, n=122) and less depersonalisation (r(s)=0.21, p=0.023, n=122), but not for any of the other outcome measures. CONCLUSIONS This study has shown that person centred approaches of care, in particular with dementia care mapping, may contribute to reducing staff job related burnout. The findings also highlight a potentially important role of managerial support and a whole of system approach.

Case-Controlled Study of Nursing Home Residents Referred for Treatment of Vocally Disruptive Behavior

The aim of this study was to identify factors associated with vocally disruptive behavior (VDB) in nursing home patients referred to aged care services for treatment, using a case-control methodology. Characteristics of the VDB, reasons for referral, perceived causal factors, and psychotropic use were noted. Twenty-five subjects and controls were examined with the Screaming Behavior Mapping Instrument, the Cornell Scale for Depression in Dementia, the Dementia Behavior Disturbance Scale, and measures of cognition, functional capacity, social activities, and emotional reactions of nursing staff. VDB was associated with other disturbed behaviors, depression, anxiety, severe dementia, functional impairment, communication difficulties, use of psychotropic medication, social isolation, and emotional distress in the nursing staff. Reasons for referral may relate more to the stress experienced by nursing home staff in managing VDB than to specific attributes of the VDB itself.
