Antenatal thyroid correlates of postpartum depression

We previously found significantly higher T3-resin uptake and nearly significantly lower total thyroxine concentrations at 38 weeks of pregnancy in women with higher postpartum depression ratings. This study further examined the relationship between thyroid status during late pregnancy and antenatal and postpartum depression scores. Thyroid measures were obtained at 32-35, 36, and 37 weeks of pregnancy in 31 women with normal range thyroid hormone levels. Subjects rated their mood at these antenatal time points and every other week between postpartum weeks 2 and 24 on the Edinburgh Postnatal Depression Scale and the Beck Depression Inventory. Mean antenatal thyroxine concentrations and free thyroxine indices correlated significantly and negatively with mean depression scores during each of three postpartum time periods (postpartum weeks 2-6, 14-18, 20-24). Women with total and free thyroxine concentrations that were, respectively, <10.1 microg/dl and <1.06 ng/dl at all three antenatal time points had significantly higher mean depression scores during all postpartum time periods. The fraction of subjects with pregravid major or minor depression history that was in the low antenatal thyroid group was significantly higher than the fraction of subjects with negative history (5/6 vs. 7/25). Women with antenatal total and free thyroxine concentrations in the lower euthyroid range may be at greater risk of developing postpartum depressive symptoms. Study of the relationships with antenatal thyroid status may provide new insights into the pathophysiology of perinatal mood disturbances.     

Predictors of postpartum depression: Prospective study of 264 women followed during pregnancy and postpartum

The prevalence of postpartum depression is approximately 13%. Postpartum depression is associated with a higher maternal morbidity and mortality, and also with pervasive effects on the emotional, cognitive and behavioral development of the child. The aim of our study was to identify socio-demographic, psychosocial and obstetrical risk factors of postpartum depression in a middle class community sample, using a prospective design. We enrolled consecutively 312 pregnant outpatients in a single maternity unit. The first assessment was conducted between 32 and 41 weeks gestation, and a second time between 6 and 8 weeks after delivery. Depressive symptoms were measured using the French version of the Edinburgh Postnatal Depression Scale (EPDS). A cut-off score of 12/30 or above was considered as indicative of Major Depression. Of the initial sample of 312 women, 264 (84.6%) were followed-up between 6 and 8 weeks after delivery and considered for analysis. Depression during pregnancy, migrant status, and physical abuse by the partner were independently associated with postpartum depression when considered together, whereas physical complications were significantly associated with postpartum depression only when adjusting for antenatal depression. Depression during pregnancy, history of physical abuse, migrant status and postpartum physical complications are four major risk factors for postpartum depression.     

Is there an association between life events,postnatal depression and thyroid dysfunction in thyroid antibody positive women?

BACKGROUND: Postnatal depression is more common in women positive for thyroid autoantibodies, independent of thyroid hormone dysfunction, but the basis of this association is unclear. AIMS: The objective of the work reported here has been to investigate from data obtained from previously published research, a possible association between life events, postnatal depression and the development of thyroid dysfunction in women who are positive for thyroid autoantibodies. METHOD: A cohort of pregnant women whose thyroid antibody status was positive (N = 115), was identified at antenatal booking (approximately 16 weeks). These, and a group of women negative for thyroid antibodies (N = 123), were assessed for depression at six to eight weeks postpartum and then at 12, 20 and 28 weeks postpartum according to Research Diagnostic Criteria (RDC). The number and type of life events over the preceding year were also assessed at eight weeks postpartum using Paykel's Life Event Schedule. At four weekly intervals post-partum until six months, thyroid antibody levels and thyroid function (plasma T3 T4 and TSH) were measured. RESULTS: As anticipated, the thyroid antibody status remained the same throughout the study, and there was no difference in the number or type of life events reported in the preceding year, between antibody positive and antibody negative women. Postnatal depression was associated with an excess of both total and negative life events, independent of thyroid antibody status or actual thyroid hormonal status. Women who developed thyroid dysfunction did not report an excess of life events (total, negative or neutral) in the preceding year. CONCLUSION: There was an excess of reported total and negative life events in women with postnatal depression, but this was independent of thyroid antibody status or function.     

Early pospartum alexithymia and risk for depression: relationship with serum thyrotropin, free thyroid hormones and thyroid autoantibodies

Most psychometric evaluations in the postpartum (PP) target depression (PPD) and show an association with thyroid autoantibodies (TAb), not with thyroid function. Three studies evaluated PP alexithymia, but none its relationship with thyroid indices. We tested 74 women aged 31.8±4.64 years, on day 3 PP, by the Edinburgh Postnatal Depression Scale (EPDS), the Montgomery and Asberg Depression Rating Scale (MADRS), and the Toronto Alexithymia Scale (TAS). Concurrently, we measured serum thyrotropin (TSH), free T3 (FT3), free T4 (FT4), thyroperoxidase and thyroglobulin antibodies (TPOAb, TgAb). Using cut-off scores of ≥12 (EPDS), ≥15 (MADRS) and ≥61 (TAS), rates of women with abnormal EPDS and MADRS scores were similar (31%, 30% and 28.4%, respectively). TAS scores were higher and proportions of alexithymics were greater in the abnormal EPDS group or in the abnormal MADRS group than in the normal EPDS or MADRS group. EPDS correlated significantly with TAS. Compared to nonalexithymics, alexythimics had lower FT4, higher FT3, lower FT4:FT3 ratio, and insignificantly higher TPOAb or TgAb levels. Only TPOAb and TgAb were significantly higher in women at risk for PPD compared to women not at risk for PPD, but solely at EPDS cut-off values of ≥13 or ≥14. TAS correlated directly with TPOAb and FT3, and inversely with FT4:FT3 ratio, while EPDS correlated only with TPOAb. Comparing women at risk for depression but nonalexithymics or women alexithymics but not at risk for depression vs. women normal on all scales, the former had lower FT3 and higher FT4:FT3 ratio while the latter had lower both FT4 and FT4:FT3 ratio. We conclude that PPD risk and alexithymia (i) are partly comorbid and directly associated with thyroid autoimmunity; (ii) their association with serum free thyroid hormones and with FT4:FT3 ratio goes in opposite directions.     

Early postpartum mood as a risk factor for postnatal depression in Nigerian women

OBJECTIVE: This report explored early postpartum mood changes and their correlation with postnatal depression in African women. METHOD: Scores on the Maternity Blues Scale and the Edinburgh Postnatal Depression Scale for 478 women on the fifth day postpartum were compared with the women's Research Diagnostic Criteria diagnosis at 4 and 8 weeks postpartum. RESULTS: The Maternity Blues Scale and the Edinburgh Postnatal Depression Scale scores at day 5 postpartum were found to reliably predict the diagnosis of depression at 4 and 8 weeks postpartum. CONCLUSIONS: African women at risk of postnatal depression can be identified in the early postnatal period by incorporating simple screening methods.     

A comparison of the performance of rating scales used in the diagnosis of postnatal depression

The results of a study looking into the association between thyroid status and depression in the postpartum period were reanalysed to explore the psychometric properties of the rating scales employed. The performance of the Edinburgh Postnatal Depression Scale was found to be superior to that of the Hospital Anxiety and Depression Scale in identifying RDC-defined depression, and on a par with the observer-rated Hamilton Rating Scale for Depression, which it also matched for sensitivity to change in mood state over time. The anxiety subscale of the Hospital Anxiety and Depression Scale performed well, reflecting the fact that anxiety represents a prominent symptom in postnatal depression.     

Thyroid function in patients maintained on lithium

To determine the clinical significance of thyroid function abnormalities in patients maintained on lithium, the authors evaluated the relationships of thyroid function tests to clinical response to lithium and side effects from lithium in 20 outpatients meeting DSM-III criteria for major affective disorder. No significant relationships were found between baseline thyroid function tests and clinical response. Thyroxine (T4) and triiodothyronine uptake ratio (T3UR) within the normal range were found to be associated with complaints of lethargy and cognitive impairment. Thirteen subjects were followed prospectively for 6 months with monthly evaluations of affective state, side effects, and occurrence of relapse. Thyroid function tests were repeated at the final visit. Final and mean T3 levels within the normal range were found to be significantly lower in patients who relapsed, and mean T3 level was inversely correlated with affective state as measured by mean scores on the Hamilton Rating Scale for Depression and the Young Mania Rating Scale.     

Prevalence and correlates of depression in late life: a population based study from a rural Greek town

BACKGROUND: Depression in late life is common and has serious consequences on function, medical co-morbidity, quality of life, and use of medical services. OBJECTIVE: To estimate the age- and gender-specific prevalence of depression among people over 60 years of age, and to examine correlates of depression, in particular the relationship between depression and cognitive impairment. METHOD: From a total of 965 inhabitants, aged over 60 years, in Velestino, a rural town in central Greece, 608 were accessible and constituted the target population. During a five-month period in 2000, a trained health visitor interviewed all study participants. The interview covered socio-demographic characteristics, medical history, and administration of the 15-question Geriatric Depression Scale (GDS-15) and the Mini Mental Scale Examination instrument (MMSE). RESULTS: The prevalence of mild or more severe depression (GDS> or =7) was 27%, while the prevalence of moderate to severe depression (GDS> or =11) was 12%. Increasing age, female gender, lower education, and being currently unmarried were associated with higher risk of depression in univariate regression models, but these associations disappeared after controlling for cognitive function, except for the association with marital status. Cognitive impairment was strongly associated with increased risk for depression. The co-morbid presence of digestive, neurological and heart conditions was also associated with increased risk for depression, while cancer was not. CONCLUSION: In a rural Greek area, the prevalence of depression in late life is high. Depression was more common among unmarried individuals, those with significant cognitive impairment, and in association with specific medical conditions.     

Screening for postnatal depression in a population-based Swedish sample

This study surveyed the prevalence of postnatal depression and demographic factors associated with it in a Swedish population. A community sample of 1584 women was screened at 8 and 12 weeks postpartum using the Edinburgh Postnatal Depression Scale (EPDS). The point prevalence of depression, using a threshold of 11/12 on the EPDS, was 12.5% at 8 weeks and 8.3% at 12 weeks postpartum. The period prevalence for 8 to 12 weeks postpartum was 4.5%. A significantly increased risk of postnatal depression was found for single women. Parity, maternal age and occupational status were not found to be related to postnatal depression. The findings suggest that screening for postnatal depression is feasible at the time of postnatal checks on the baby, and that it can aid in the identification of women at risk for depression. A two-stage screening procedure will identify women at risk for more persistent postnatal depression.     

Does cognitive recovery after treatment of poststroke depression last? A 2-year follow-up of cognitive function associated with poststroke depression

OBJECTIVE: Cognitive impairment is common after stroke and may be caused by poststroke depression. Remission of poststroke major depression after treatment has been associated with improvement in cognitive function. The current study was designed to examine how long that cognitive improvement lasts and to compare depressed patients' cognitive status with that of nondepressed patients with comparable lesions. METHOD: Seventeen patients with poststroke depression and cognitive impairment who had early and sustained remission of their depression during a double-blind treatment study were compared with 42 nondepressed stroke patients who remained nondepressed throughout the follow-up. Mood and cognitive function were followed-up over 2 years with the Hamilton Depression Rating Scale and Mini-Mental State Examination (MMSE). RESULTS: In the patients with early and sustained remission of depression, there was rapid improvement of cognitive function, which was maintained over 2 years. Their initial MMSE score of 23.3 (SD=4.2) improved to 26.6 (SD=3.5) at 3 months and was 26.1 (SD=3.6) at 2 years. The nondepressed patients showed essentially no change in cognitive function over 2 years (initial MMSE score: mean=26.3, SD=3.1; score at 2-year follow-up: mean=25.7, SD=4.1). CONCLUSIONS: Cognitive function, once improved after remission of poststroke depression, is likely to remain stable over the next 2 years in the absence of subsequent reinjury to the central nervous system. Cognitive impairment due to poststroke depression is reversible and can be quantified separately from cognitive impairment on the basis of the location and extent of ischemic brain damage.     

Effects of pharmacological therapy on gait and cognitive function in depressed patients

OBJECTIVE: To investigate the relationship among affective status, cognitive function, and gait in depressed patients and to evaluate the effects of treatment of depression on gait and cognitive function. METHODS: Nineteen patients recently diagnosed with clinical depression (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) were recruited from a psychiatric outpatient clinic. Evaluation included the Hamilton Depression Rating Scale (HAM-D), the Mini-Mental State Examination, a computerized neuropsychological battery (Mindstreams, NeuroTrax Corp, New York, NY), and Barthel's Index of Instrumental Activities of Daily Living. Temporal parameters of gait were quantified using a stopwatch and force-sensitive insoles. All assessments were performed at baseline and after approximately 10 weeks of treatment with antidepressants. RESULTS: The patients' mean age was 68.6 +/- 9.1 years (15 women). Therapy significantly (P < 0.001) improved the affective state (HAM-D scores). There were small but significant improvements in gait speed (P = 0.033), stride time variability (P = 0.036), and gait asymmetry (P = 0.038). With the exception of the hand-eye coordination index, all tested cognitive domains also improved significantly. Baseline depression scores correlated with changes in depression: patients with higher HAM-D scores at baseline had more significant improvement in their affect (P < 0.001). Changes in HAM-D were not significantly correlated with changes in gait or changes on computerized tests of cognitive function (P > 0.10). CONCLUSIONS: Depressive symptoms are associated with gait and cognitive impairment. Moreover, the present results suggest that these domains improve in response to antidepressant medication.     

Depressive symptomatology in the immediate postnatal period: identifying maternal characteristics related to true- and false-positive screening scores.

OBJECTIVE: To determine whether true- and false-positive postnatal depression screening scores can be distinguished during the early postpartum period by examining characteristic differences between 2 groups: 1) women with depressive symptomatology at 1 week postpartum who continue to exhibit symptoms at 8 weeks postpartum, compared with those who do not; and 2) women with depressive symptomatology at 8 weeks postpartum who previously exhibited symptoms at 1 week postpartum, compared with those who did not. METHOD: As part of a longitudinal postpartum depression study, a population-based sample of 594 women completed mailed questionnaires at 1, 4, and 8 weeks postpartum. RESULTS: Among women with depressive symptomatology at 1 week postpartum, diverse variables distinguished between those whose symptoms persisted or remitted at 8 weeks. These variables included recent immigrant status, psychiatric history, premenstrual symptoms, vulnerable personality, low self-esteem, child abuse history, and insufficient support. Variables that distinguished between women with depressive symptomatology at 8 weeks postpartum who previously exhibited symptoms at 1 week postpartum and those who did not included vulnerable personality, life stressors, perceived stress, insufficient support, and partner conflict. CONCLUSIONS: To address both the benefits and potential harms of early screening, positive screening scores on the Edinburgh Postnatal Depression Scale should also include an assessment of each individual woman's risk for postpartum depression and (or) chronic major depression.     

The use of paroxetine and cognitive-behavioral therapy in postpartum depression and anxiety: a randomized controlled trial

BACKGROUND: Approximately 10% to 16% of women experience a major depressive episode after childbirth. A significant proportion of these women also suffer from comorbid anxiety disorders. The purpose of this study was to evaluate whether the addition of cognitive-behavioral therapy (CBT) to standard antidepressant therapy offers additional benefits in the treatment of post-partum depression with comorbid anxiety disorders. METHOD: Thirty-five women referred to a tertiary care hospital outpatient program with a DSM-IV diagnosis of postpartum depression with comorbid anxiety disorder were randomly assigned to 1 of 2 treatment groups-paroxetine-only monotherapy group (N = 16) or paroxetine plus 12 sessions of CBT combination therapy group (N = 19)-for a 12-week trial. Progress was monitored by a psychiatrist blinded to treatment group, using the Hamilton Rating Scale for Depression, Hamilton Rating Scale for Anxiety, Yale-Brown Obsessive Compulsive Scale, Clinical Global Impressions scale, and Edinburgh Postnatal Depression Scale. Data were analyzed using 2-tailed statistical tests at an alpha level of.05. The study was conducted from April 1, 2002, to June 30, 2003. RESULTS: Both treatment groups showed a highly significant improvement (p <.01) in mood and anxiety symptoms. Groups did not differ significantly in week of recovery, dose of paroxetine at remission, or measures of depression, anxiety, and obsessive-compulsive symptoms at outcome. CONCLUSION: Antidepressant monotherapy and combination therapy with antidepressants and CBT were both efficacious in reducing depression and anxiety symptoms. However, in this sample of acutely depressed/anxious postpartum women, there were no additional benefits from combining the 2 treatment modalities. Further research into the efficacy of combination therapy in the treatment of moderate-to-severe depression with comorbid disorders in postpartum women is recommended.     

The Edinburgh Postnatal Depression Scale: validation on a Swedish community sample

The Edinburgh Postnatal Depression Scale (EPDS) was designed to be used by community health workers to screen for postnatal depression. We report data from a population-based sample of 1655 women who completed the EPDS at 2 months and 3 months postpartum. A total of 128 women were interviewed with the Montgomery Asberg Depression Rating Scale (MADRS) and assessed according to DSM-III-R criteria for major depression. A cut-off score of 11.5 on the EPDS identified all but two women with major depression, giving it a sensitivity of 96%, a specificity of 49% and a positive predictive value of 59%. This study supports the validity of the EPDS shown in earlier studies, and indicates that the scale is a useful screening instrument for identifying postnatal depression in primary health care in Sweden.

Impact of cognitive impairment on the phenomenology of geriatric depression.

OBJECTIVE: Dementia and depressive syndromes demonstrate substantial symptom overlap. As a result, it is challenging to differentiate depression symptoms from nonspecific symptoms of an underlying dementia syndrome. The author addressed the impact of cognitive impairment on the phenomenology of depression symptoms by determining whether more impaired patients were more likely to endorse certain self-report depressive symptoms independent of their underlying level of depression severity. METHODS: Author used data from 576 geriatric rehabilitation inpatients for MIMIC model analyses examining the impact of cognitive impairment on both depression severity and endorsement of symptom clusters. Depressive symptoms were measured with the Geriatric Depression Scale, and cognitive impairment was measured with the Mattis Dementia Rating Scale total score. RESULTS: The reliability (internal consistency) of self-reported depressive symptoms did not change as a function of cognitive impairment. More severe cognitive impairment was associated with greater depression severity but was also associated with two depression symptom clusters after controlling for underlying levels of depression severity. Patients who were more impaired endorsed greater social withdrawal and less psychomotor agitation, independent of their underlying depression severity. Level of cognitive impairment alone did not affect the endorsement of depressed mood and positive affect. CONCLUSIONS: Certain symptoms on depression inventories may be endorsed at a greater level by cognitively impaired patients, independent of their level of underlying depression severity. These symptoms may be nonspecific features of the underlying dementia syndrome and may not be specific to depressive episodes, but instead may represent other syndromes, such as apathy.     

Cognitive function,depression, anxiety and quality of life in Chinese patients with untreated unruptured intracranial aneurysms

Detected unruptured intracranial aneurysms (UIA) are becoming more common with the increased utilization of CT angiography, MR angiography and digital subtraction angiography. A proportion of patients with UIA remain untreated. We investigated to assess cognitive function, depression, anxiety and quality of life (QoL) in Chinese patients with untreated UIA. Thirty one Chinese patients with untreated UIA and 25 healthy controls were identified and matched for variables including age, sex, and living area. Cognitive function was evaluated with the Montreal Cognitive Assessment (MoCA). Depression, anxiety and QoL were screened with the Self-Rating Depression Scale, Self-Rating Anxiety Scale, and Short Form-36, respectively. Non-parametric tests were used for comparisons between groups. No patient had cognitive dysfunction at 1 month or 1 year after detection of UIA. However, a significant decrease of overall MoCA subscores was found in 30 (97%) of 31 patients 5 years after UIA discovery, suggestive of mild cognitive impairment. A significant decrease in depression and anxiety was found in patients over time. QoL in patients was reduced most prominently in psychosocial function and social activities 1 year after detection of UIA, but these improved to within normal limits at the end of the follow-up period. For Chinese patients with untreated UIA, depression, anxiety and reduced QoL may be short-term complications. Mild cognitive impairment may be a long-term complication.     

Computerized cognitive testing battery identifies mild cognitive impairment and mild dementia even in the presence of depressive symptoms

Cognitive and depressive symptoms co-occur, complicating detection of mild cognitive impairment (MCI) and early dementia. In this study, discriminant validity of a novel computerized cognitive battery for MCI detection was evaluated after covariation for depressive symptom severity. In addition to the computerized battery, participants at two sites received the 30-item self-administered Geriatric Depression Scale (GDS; n=72); those at two other centers received the observer-administered Cornell Scale for Depression in Dementia (CSDD; n=88). In both cohorts, a Global Cognitive Score and memory, executive function, visual spatial, and verbal index scores discriminated among cognitively healthy, MCI, and mild dementia groups after covariation for GDS or CSDD, respectively (p < 0.05). Thus, the computerized battery for detection of mild impairment is robust to comorbid depressive symptoms, supporting its clinical utility in identifying neurodegenerative disease even in elderly with depression.     

Nutrient intake and psychological health in an elderly Chinese population

BACKGROUND: Associations between nutrition and cognitive impairment, and nutrition and depression, have been observed. Elderly people are at risk of under nutrition, and also have higher prevalence of cognitive impairment and depression. OBJECTIVE: To examine the relationship between nutrient intake and psychological health in the elderly, adjusting for confounding factors. SUBJECTS: Three thousand nine hundred and ninety-nine men and women aged 65 years and over living in the community, with approximately equal numbers in three age groups: 65-69, 70-74, 75+ years. METHODS: Dietary intake was assessed using a 7-day food frequency questionnaire. Cognitive function was assessed by the cognitive part of the Community Screening Instrument for Dementia (CSID). Depression was assessed using the Geriatric Depression Scale (GDS). Information was also collected for confounding factors: demographics, educational level, socioeconomic status, medical history, smoking, alcohol intake, and physical activity. Logistic regression analyses were carried out to examine associations between lifestyle and dietary variables, and CSID and GDS, controlling for confounders. RESULTS: Both CSID and GDS scores were associated with co-morbidity, demographic and socioeconomic factors. Few associations between lifestyle factors and CSID score were observed. Dietary factors inversely associated with GDS score include total fat intake, vitamins A, B2, B3, C, fibre, and vegetables. In terms of nutrient density, iron and isoflavone intake were additional factors. CONCLUSION: Association exists between intake of various nutrients and psychological health independent of other confounding factors in the elderly population. A follow-up study of this cohort or interventional studies are needed to elucidate cause effect relationship.     

To what extent does frontal type executive impairment affect coping strategies in Parkinson’s disease?

Background and purpose: Given the frequency of executive dysfunction in Parkinson’s disease (PD), we wonder to what extent this fact might influence the coping strategies which are used. Methods: A total of 135 PD patients with no dementia were divided into two groups according to their cognitive status (‘with frontal type executive impairment’ or ‘without frontal type executive executive impairment’). All patients were seen for a semi‐structured interview to collect sociodemographic and clinical information and to assess their cognitive and mental states (DSM‐IV‐TR, frontal assessment battery and Montgomery and Asberg Depression Rating Scale). Then, all patients completed two self‐report questionnaires concerning their coping strategies (Ways of Coping Checklist and Coping with Health, Injuries and Problems Scale). Results: After controlling the depression, we noticed a significant effect of cognitive status on positive re‐evaluation (P = 0.02). Interestingly, except for instrumental strategies, patients with frontal type executive impairment used significantly more coping strategies than did patients without frontal type executive impairment. Conclusion: Our results suggest that neither executive impairment nor depression prevents patients from using coping strategies extensively.
