Hui A. Exploring the utility of RDoC in differentiating effectiveness amongst antidepressants: A systematic review using proposed psychometrics as the unit of analysis for the Negative Valence Systems domain. PLoS One 2020; 15:e0243057. [PMID: 33326436 PMCID: PMC7743972 DOI: 10.1371/journal.pone.0243057] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Accepted: 11/14/2020] [Indexed: 01/26/2023] Open
Abstract
Background RDoC conceptualises psychopathology as neurobiologically-rooted behavioural psychological “constructs” that span dimensionally from normality to pathology, but its clinical utility remains controversial. Aim To explore RDoC’s potential clinical utility by examining antidepressant effectiveness through Negative Valence Systems (NVS) domain constructs. Method A systematic review was conducted on Web of Science, MEDLINE, EMBASE and PsycINFO for antidepressant trials that included psychometric instruments assessed by Watson, Stanton & Clark (2017) to represent NVS constructs of Acute Threat, Potential Threat and Loss. Results 221 citations were identified; 13 were included in qualitative synthesis, none for quantitative analysis. All suffered from significant bias risks. 9 antidepressants were investigated, most within 1 construct, and most were found to be effective. Paroxetine, citalopram and fluvoxamine were found to be effective for Acute Threat, fluoxetine, desvenlafaxine and sertraline for Potential Threat, and sertraline, fluvoxamine, fluoxetine and desvenlafaxine effective for Loss. Nefazodone was found to be ineffective for acute fear. Conclusion Preliminary evidence supports RDoC NVS constructs’ clinical utility in assessing antidepressant effectiveness, but lack of discriminant validity between Potential Threat and Loss supports their recombination into a single Distress construct. Finding of effectiveness within “normal” construct levels support the utility of a dimensional approach. Testable hypotheses were generated that can further test RDoC’s clinical utility.

Efficacy and tolerability of pharmacological and non-pharmacological interventions in older patients with major depressive disorder: A systematic review, pairwise and network meta-analysis. Eur Neuropsychopharmacol 2019; 29:1003-1022. [PMID: 31327506 DOI: 10.1016/j.euroneuro.2019.07.130] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Revised: 06/25/2019] [Accepted: 07/09/2019] [Indexed: 01/01/2023]
Abstract
As there is currently no comprehensive evaluation about the efficacy and safety of interventions in elderly patients with major depressive disorder, we did a systematic review and network meta-analysis about all interventions in this population. We searched the specialised register of the Cochrane common mental disorders group, MEDLINE, EMBASE, PsycINFO, CochraneLibrary, ClinicalTrials.gov and the WHO registry until Dec 12, 2017 to identify all randomized controlled trials about the treatment of major depressive disorder in patients over an age of 65. The primary outcome was response defined as reduction of at least 50% on the Hamilton Depression Scale or any other validated depression scale. Secondary outcomes were remission, depressive symptoms, dropouts total, dropouts owing to inefficacy and dropouts due to adverse events, quality of life and social functioning. Additionally, we analysed 116 adverse events. We identified 129 references from 53 RCTs with 9274 participants published from 1990 to 2017. The mean participant age was 73.7 years. In terms of the primary outcome response to treatment the network-meta-analysis showed significant superiority compared to placebo for quetiapine and duloxetine; in addition, agomelatine, imipramine and vortioxetine outperformed placebo in pairwise meta-analyses, and there were also significant superiorities of several antidepressants compared to placebo in secondary efficacy outcomes. Very limited evidence suggests that competitive memory training, geriatric home treatment group and detached mindfulness condition reduce depressive symptoms. Several antidepressants and quetiapine have been shown to be efficacious in elderly patients with major depressive disorder, but due to the comparably few available data, the results are not robust. Differences in the multiple side-effects analysed should also be considered in drug choice. Although there were significant effects for some non-pharmacological treatments, the overall evidence for non-pharmacological treatments in major depressive disorder is insufficient, because it is based on a few trials with usually small sample sizes.

Abstract
BACKGROUND There are high rates of cognitive problems and organic and functional psychiatric disorders in patients admitted to general hospital wards, which may necessitate the use of psychotropic medications. There is evidence of over-prescription of medications such as antipsychotics and antidepressants in community settings such as residential care. However, the prevalence of psychotropic use in general hospitals is unknown. METHODS A point prevalence study of the use of psychotropic medications in an acute general hospital was conducted by auditing medication charts for type, dose, indication, and other clinical processes associated with their use. RESULTS The files of 197 patients were audited, 139 (70%) were aged 65 years and over. Eighty-nine (45%) of patients were prescribed a psychotropic, with 35 (17.7%) antidepressants; 21 (11%) antipsychotics; 19 (10%) benzodiazepines; six (3%) mood stabilizer; five (2%) cholinesterase inhibitors; one (0.5%) anti-parkinsonian medication, and one (1%) patient on zolpidem and another patient melatonin (1%). Most prescriptions (72%) were in people 65 years and over and 27 (20%) of indications were found to be off label prescribing. There were deficits in the documentation of indications for the use of psychotropic medications and follow up arrangements. CONCLUSIONS Rates of benzodiazepines use were less than that reported incomparable settings. Concerns regarding off label prescribing, under-dosing, and lack of adequate documentation of indications and follow-up instructions were raised. Given the potential adverse effects of psychotropic medication, improved governance, and education regarding their use is required.

Abstract
BACKGROUND Depression is common in the elderly and in the last few years this led to a significant increase in antidepressant prescription rates. However, little is known about antidepressant efficacy profile in relation with socio-demographic and clinical features in this population. The aim of the present study was to define the most suitable socio-demographic and clinical profile for the use of antidepressant treatments in late-life depression. METHODS MEDLINE, EMBASE and PsycINFO were searched for randomized controlled trials (RCTs) focused on efficacy of antidepressants of all classes in major depressed elderly subjects (>60 years old). Reviews and meta-analyses focusing on this topic have been considered as well. Thirty-four RCTs were included and socio-demographic and clinical features were investigated via meta-regression analysis as moderators of efficacy measures (standardized mean difference based on Hamilton Depressive Rating Scale and Montgomery-Asberg Depression Rating Scale). RESULTS A lower rate of response to antidepressants of all classes was found in patients of male gender, of older age, and with a longer mean duration of the current episode. On the contrary, a higher rate of response was found in patients with a higher baseline severity and at their first episode of illness. Subsamples treated with selective serotonin reuptake inhibitors alone yielded similar results. LIMITATIONS RCTs only have been included. CONCLUSIONS A number of socio-demographic and clinical features have been found to moderate antidepressant efficacy in elderly population. Those variables could help clinicians for a more individualized treatment.

Abstract
The elderly frequently have changes in pharmacokinetics, sensitivity to medications, homeostatic reserve (ability to tolerate physiological challenges), exposure to multiple medications, and adherence. All of these age-associated factors can potentially influence total exposure to medication, adverse effects, and subsequent treatment outcome. Most clinical trials are performed with healthy, younger adults. Extrapolating the results of these trials to the elderly may be inappropriate, particularly for the antidepressant treatment of depression. The authors review these age-associated differences and discuss their implications for antidepressant use in older adults.

Abstract
OBJECTIVE To determine the efficacy and tolerability of citalopram when compared to other antidepressants for late-life depression (LLD). METHODS We searched electronic databases and trial registries to identify randomized controlled trials comparing citalopram to other antidepressants for LLD. Study quality was assessed using the Cochrane collaboration risk of bias tool. We summarized the efficacy of citalopram compared to other antidepressants by examining rates of depression remission, depression response and change in depression symptom scores. Medication tolerability was assessed through trial withdrawals due adverse events and withdrawals due to any cause. We used meta-analysis to determine the odds ratios (OR) of efficacy and tolerability outcomes for citalopram compared to other antidepressants. RESULTS Seven studies comparing citalopram (N = 647) to other antidepressants (N = 641) for LLD were identified including four studies with tricyclic comparators and three studies with non-tricyclic comparators. Most of the studies had methodological limitations that placed them at risk for potential bias. The majority of studies reported no significant differences between citalopram and comparator medications for depression efficacy or tolerability outcomes. Meta-analysis did not find any significant differences between citalopram and other antidepressants for depression remission [OR = 0.84; 95%CI: 0.56-1.28] or for trial withdrawals due to adverse effects [OR = 0.70; 95%CI: 0.48-1.02]. CONCLUSIONS Currently there are few studies directly comparing citalopram to other antidepressants for LLD. The small number of studies and methodological issues in many studies limit any conclusions about the relative efficacy and tolerability of citalopram compared to other antidepressants. Well-designed studies comparing citalopram to other antidepressants for LLD are required.

Abstract
AIM Generalized anxiety disorder (GAD) in elderly people is common, but few systematic studies regarding the best treatments have been performed. The aim of the present study was to evaluate the efficacy and safety of sertraline and buspirone in the treatment of elderly patients with GAD. METHODS Based on selection criteria, 46 patients were recruited who met DSM-IV criteria for GAD. Patients were randomly assigned to sertraline (50-100 mg/day) or buspirone (10-15 mg/day) for 8 weeks in a single-blind trial. The primary outcome measure used in the present study was the Hamilton Rating Scale for Anxiety (HRSA). RESULTS Both sertraline and buspirone had significant anxiolytic efficacy. A steady decrease in the total HRSA scores for both groups was observed throughout the study period. After 2 and 4 weeks, buspirone was found to be significantly superior to sertraline (P < 0.001), but at the end of study period this difference did not reach statistical significance (P = 0.16). The mean HRSA score after 8 weeks significantly decreased in subjects treated with sertraline (P < 0.001), and buspirone (P < 0.001). No clinically adverse events or changes in laboratory test results were observed during the study period. CONCLUSION Both sertraline and buspirone appear to be efficacious and well tolerated in the treatment of GAD in elderly patients. Further studies with larger sample size, evaluating the effect of medical illness, cognitive impairment, depression, and combined therapy with support and psychotherapy are needed.

Abstract
CONTEXT Adjunctive restorative therapies administered during the first few months after stroke, the period with the greatest degree of spontaneous recovery, reduce the number of stroke patients with significant disability. OBJECTIVE To examine the effect of escitalopram on cognitive outcome. We hypothesized that patients who received escitalopram would show improved performance in neuropsychological tests assessing memory and executive functions than patients who received placebo or underwent Problem Solving Therapy. DESIGN Randomized trial. SETTING Stroke center. PARTICIPANTS One hundred twenty-nine patients were treated within 3 months following stroke. The 12-month trial included 3 arms: a double-blind placebo-controlled comparison of escitalopram (n = 43) with placebo (n = 45), and a nonblinded arm of Problem Solving Therapy (n = 41). OUTCOME MEASURES Change in scores from baseline to the end of treatment for the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Trail-Making, Controlled Oral Word Association, Wechsler Adult Intelligence Scale-III Similarities, and Stroop tests. RESULTS We found a difference among the 3 treatment groups in change in RBANS total score (P < .01) and RBANS delayed memory score (P < .01). After adjusting for possible confounders, there was a significant effect of escitalopram treatment on the change in RBANS total score (P < .01, adjusted mean change in score: escitalopram group, 10.0; nonescitalopram group, 3.1) and the change in RBANS delayed memory score (P < .01, adjusted mean change in score: escitalopram group, 11.3; nonescitalopram group, 2.5). We did not observe treatment effects in other neuropsychological measures. CONCLUSIONS When compared with patients who received placebo or underwent Problem Solving Therapy, stroke patients who received escitalopram showed improvement in global cognitive functioning, specifically in verbal and visual memory functions. This beneficial effect of escitalopram was independent of its effect on depression. The utility of antidepressants in the process of poststroke recovery should be further investigated.

Abstract
During his professional practice the author encountered a case of coexistence of "major depression" with psychic depressive attacks (dysthymic attacks) of so-called temporal epilepsy. Apart from major depression of medium intensity, other manifestations developed. These were independent of the time of the day, suddenly occurring within several seconds, developing without any cause, attacks of very strong dejection, sadness, breakdown, feeling of lacking sense and hopelessness of life with slight lessening of consciousness and strong groundless fear. Detailed psychiatric examinations, observations of the patient during such attacks and EEG records confirmed the diagnosis of dysthymic attacks of temporal epilepsy. The author treated the patient with sertraline starting at a low dose and increasing up to 100 mg daily - administered orally once daily in the morning, clonazepam in oral doses 1 mg in the morning, 1 mg at lunchtime, 2 mg in the evening, and carbamazepine 200 mg tablets from low doses to 400 mg administered once daily in the evening. Complete remission of major depression and complete regression of dysthymic attacks of "temporal epilepsy" were obtained.

Abstract
Instruments with acceptable measurement properties that support their application to older adults across a range of settings need to be identified. A narrative literature review of empirical studies investigating the conceptualization and measurement of quality of life (QoL) among older adults from 1994 to 2006 was performed. The review focused on evidence provided for conceptual frameworks, QoL definitions, types of measurements utilized and their psychometric properties. Two searches were conducted. The first search conducted in 2004 used Cinahl, Medline, PsycInfo, Embase and Cochrane databases. A supplemental search was conducted in December 2006, which included these bases from 2004 to 2006, and Sociological Abstracts and Anthropological literature base. The review included 47 papers. A total of 40 different measurements were applied in the studies, assessing most frequently functional status and symptoms. The most extensive psychometric evidence was documented for the SF-36. Although construct validity was reported in the majority of studies, minimal empirical evidence was given for other psychometric properties. Further, 87% of the studies lacked a conceptual framework and 55% did not report any methodological considerations related to older adults. Quality control standards, which can guide measurement assessment and subsequent data interpretation, are needed to enhance more consistent reporting of the psychometric properties of QoL instruments utilized. Future work on the development of common QoL assessment models that are both person-centered, causal and multidimensional based on collaborative efforts from professionals interested in QoL from the international gerontological research community are needed.

Abstract
BACKGROUND Total or partial sleep deprivation was showed to have rapid antidepressive effects in depression. Sleep deprivation therapy in major depression constitutes insufficient antidepressive treatment response and depressive symptoms reoccur after one night of recovery. Combination of antidepressant medication with sleep deprivation therapy is generally indicated. These combination therapies were found more favorable overall therapeutic effect than antidepressive monotherapy. METHODS In this study, we examined the Quality of Life changes with the antidepressive therapy using partial sleep deprivation plus sertraline and sertraline monotherapy in patients with major depressive disorder. Thirteen patients received six partial sleep deprivation therapies in addition to sertraline, that sleep schedule in deprivation nights started at 11:00-12:00 p.m. to 03:00 a.m. and 11 patients treated with sertraline monotherapy as a control group. Quality of Life was evaluated with the WHOQOL-100, depression and the accompanying anxiety were also assessed at baseline and at the end of the 4th week. RESULTS Patients treated with combination therapy improved significantly and more rapidly. Rapid improvement in quality of life in major depressive disorder was showed in patients treated with combination of late partial sleep deprivation and sertraline. LIMITATIONS Small sample size, the lack of placebo group and short duration of the study are the main limitations. CONCLUSIONS In clinical practice, QOL improvement can be accelerated using combination of partial sleep deprivation with the sertraline therapy.

Abstract
DSM-IV has recommended use of the Social and Occupational Functioning Scale (SOFAS) as a clinician-rated global assessment scale for measuring social functioning; this scale is analogous to the Clinical Global Impression (CGI) scale traditionally used as a secondary outcome measure in patients with depressive symptoms. However, we believe that health-related quality of life is the most appropriate indicator of social functioning when considering this dimension as an endpoint in clinical trials of antidepressants. As health-related quality of life is a purely subjective measure, patient-rated questionnaires have been found to be most important in this context. In this respect, the Sheehan Disability Scale has been recommended as the most relevant global self-reported assessment of social functioning in trials of antidepressants.A review of questionnaires found that the three most frequently used scales selectively directed at obtaining information about social functioning in trials of antidepressants are the Social Adjustment Scale - Self Report (SAS-SR), the Social Adaptation Self-Evaluation Scale (SASS) and the Short-Form Health Survey (SF-36). However, the number of placebo-controlled trials of antidepressants that have used these scales is still too limited to allow comparisons in terms of responsiveness.Health-related quality of life includes dimensions other than social functioning, e.g. physical health and mental health (including both cognitive and affective problems). The SF-36 includes subscales relating to physical and mental health, which, like the social functioning subscales, are measured in terms of degrees of well being. Another quality-of-life questionnaire, the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), covers social, mental and physical problems, in this case measured in terms of degrees of satisfaction. Recently, the Q-LES-Q has been reduced from a comprehensive scale including 60-92 items to a brief version including 15 items. An additional item measures overall life satisfaction. As most of the items in the brief Q-LES-Q include social functioning, the scale can be considered as an alternative to SF-36 or the Sheehan Disability Scale when the focus is on satisfaction with treatment. However, there are insufficient numbers of trials of antidepressants using these questionnaires to allow comparisons. The examples of trials of antidepressants with the SF-36 subscales discussed in this review have mostly involved SSRIs. These trials have demonstrated that although antidepressants improve social functioning compared with placebo over a 6-week treatment period, the endpoint scores are still significantly below the national norms at this point. Only after 12 weeks of therapy are the endpoint scores of the social functioning scales within the limits of the national norms. In relapse prevention trials or in maintenance trials to prevent recurrence of depression, comparisons of social functioning scores with national norms can be important supplementary indicators of the need for treatment. In conclusion, social functioning as part of the health-related concept of the patient-reported quality-of-life measure should constitute an endpoint in trials of antidepressants to help clarify the goals of treatment in patients with major depression. In medium- and long-term trials, SF-36 subscales should be used as a supplement to symptom-orientated scales. In trials of shorter (6-8 weeks) duration, use of other scales such as the SAS-SR, the Q-LES-Q or the Sheehan Disability Scale should be considered. These scales should be considered as supplementary to each other rather than alternatives; it may be necessary to use more than one of these scales in a trial.

In consecutive dosing periods separated by washout periods of > or = 3 weeks, healthy volunteers received either oral donepezil HCI 5 mg once daily for 15 days, oral sertraline HCl 50 mg once daily for 5 days followed by 10 days of once-daily sertraline HCl 100 mg, or the simultaneous administration of oral donepezil HCl and sertraline HCl. Plasma donepezil and sertraline concentrations were determined by high performance liquid chromatography/mass spectrometry. Safety was evaluated by physical and laboratory evaluations and the monitoring of adverse events (AEs). RESULTS A total of 19 volunteers (16 male and three female) were enrolled. Three male subjects withdrew from the study prematurely due to AEs (one case of nausea/stomach cramps and one case of eosinophilia during combination treatment, and one upper respiratory tract infection during treatment with sertraline HCl alone). In subjects who completed all three treatment periods (n = 16), the concurrent administration of donepezil HCl and sertraline HCl did not alter the steady-state (day 15) PK parameters of donepezil HCl. A small (< 12%) but statistically significant (P = 0.02) increase in donepezil C(max) was seen after single doses of sertraline HCl and donepezil HCl on day 1 but this was not thought to be clinically meaningful. No significant differences in the t(max) or AUC(0-24 h) of donepezil were observed between the donepezil HCl only or donepezil HCl plus sertraline HCl groups on day 1. No significant changes in sertraline PK parameters were observed either on day 1 (single dose) or on day 15 (steady state) when sertraline HCl was co-administered with donepezil HCl. Generally, the concurrent administration of donepezil HCl and sertraline HCl was well tolerated, with no serious AEs reported during the study. Some digestive system AEs tended to occur more frequently during combination treatment than with either treatment alone, but there was no statistically significant increase in the incidence of any individual AE. The most common AEs during the combination therapy were nausea and diarrhoea, which were rated as mild or moderate in severity. These AEs were also reported during the administration of each drug alone. CONCLUSIONS The co-administration of once-daily oral donepezil HCl 5 mg for 15 days and once-daily oral sertraline HCl (50 mg for 5 days increased to 100 mg for 10 days) did not result in any clinically meaningful pharmacokinetic interactions, and no unexpected AEs were observed.

Abstract
While it is generally accepted that cognitive processes such as learning and memory are affected by emotion, the impact of depression on learning and memory has rarely been directly studied in experimental animals. Effects of induced depressive behavior on learning and memory were determined in rats, using an open space swim test, a novel animal model of depressive behavior that is developed recently in our laboratory. The model indexes searching activity of the animals, with the induced depressive immobility behavior showing specific sensitivity to three major prototypic classes of antidepressants and a selective serotonin reuptake inhibitor. The induced depressive behavior in rats showed a delayed response to chronic antidepressant treatment and had a lasting effect on the ability of rats to learn and recall the learned experience. It impaired the subsequent ability of rats to learn and recall both a spatial water maze task and a multi-trial passive avoidance task. These impairments were all sensitive to antidepressant therapeutics, but not to buspirone, an anxiolytic. By way of contrast, the ability of the rats to sense and move to a visible platform and to escape from an unconditioned shock stimulus was neither impaired by inducing the depressive behavior nor altered by the drug treatment, suggesting that non-specific changes in sensorimotor ability were not involved. These impairments of learning and memory indicate that the depressive behavior-induced deficits show generalizability and are not context-limited. This animal model of depressive behavior shows promising potential as a screen for novel antidepressive therapeutics and as a disease model for revealing network/cellular/molecular mechanisms in the pathophysiology of depression and depression-induced cognitive deficits.

Abstract
Treatment response and side effects of venlafaxine were evaluated in an open-label trial of elderly outpatients with dysthymic disorder (DD). Patients received flexible dose (up to 300 mg/d) venlafaxine (Effexor XR) for 12 weeks. Of 23 study patients, 18 completed the trial. Fourteen (60.9%) were responders in intent-to-treat analyses with the last observation carried forward, and 77.8% were responders in completer analyses. Nearly half the sample (47.8%) met criteria for remission. In the intent-to-treat sample, increased severity of depression at baseline was associated with superior response, and the presence of cardiovascular disease was associated with poorer response. Venlafaxine open-label treatment was associated with fairly high response rates and generally good tolerability in elderly patients with DD. These results indicate that in elderly patients with DD, placebo-controlled trials of a dual reuptake inhibitor such as venlafaxine would be needed to assess its efficacy or to compare its efficacy to that of other antidepressants.

Abstract
According to the DSM-IV classification, a diagnosis of Major Depressive Disorder (MDD) is possible only when there is evidence of significant inference with functioning. However, despite the high prevalence of MDD in the general population, it is uncommon for clinicians to assess overall functioning in a systematic way before making such diagnosis. An important correlate of functioning is quality of life, which is typically defined as "patients' own assessments of how they feel about what they have, how they are functioning, and their ability to derive pleasure from their life activities". In the present article, we review studies focusing on the relationship between depression and quality of life, particularly focusing on the impact of the treatment of depression on quality of life. Studies focusing on the quality of life in MDD are reviewed. Candidate studies published between 1970 and recently were initially identified by Pubmed and Ovid search cross-referencing the terms "quality of life," "psychosocial functioning" with "major depression" and "treatment." A number of studies report poorer quality of life in MDD patients compared to controls. Several studies also report an improvement in quality of life measures during various phases of treatment with antidepressants and/or psychotherapy. However, trials comparing the role of newer psychopharmacologic agents in the acute phase of treatment, and the role of newer psychotherapies in the continuation and maintenance phases of treatment in restoring psychosocial functioning and improving the quality of life in MDD are lacking. Exploring the impact of these modalities on psychosocial function and quality of life in MDD are necessary to help translate clinical response into restoration of psychosocial function and to thus further improve the standard of care.

Abstract
Despite a common mode of action [inhibition of the 5-hydroxytryptamine (5-HT) neuronal reuptake transporter], proven antidepressant efficacy and a similar range of indications (depression and a variety of anxiety disorders), the unique secondary binding properties of each selective serotonin reuptake inhibitor (SSRI) account for clinically significant differences in tolerability and side-effect profiles, particularly in some patients. Secondary properties within the class of SSRIs include some combination of actions at noradrenergic, dopaminergic, muscarinic cholinergic, histaminergic and sigma receptors. In addition, most SSRIs inhibit at least one of the cytochrome P450 enzymes, resulting in potential pharmacokinetic interactions with co-prescribed drugs. Although secondary properties of SSRIs can be associated with side effects, sometimes these same actions can be harnessed to good therapeutic effect through rational, informed treatment choices. In this way, agents that more consistently cause central nervous system activation (such as fluoxetine and sertraline) can be used to boost energy in patients whose depression is accompanied by fatigue and apathy, while the anxiolytic, sedative properties of others (particularly paroxetine and fluvoxamine) can be beneficial in patients with insomnia and agitation. When secondary properties are experienced as undesirable side effects, agents with greater selectivity for the serotonin transporter and without significant secondary binding properties, such as citalopram and escitalopram, may be desirable. This article explains how an understanding of the secondary binding properties of the SSRIs can guide individualised treatment across the spectrum of depressive and anxious states.

Abstract
Weight loss and anorexia are common problems that are associated with increased morbidity and mortality in the growing frail elderly population. Orexigenic agents are often prescribed in an attempt to improve appetite and lean muscle mass. Much of the data regarding their benefit comes from studies involving younger patients with illnesses such as acquired immunodeficiency syndrome or cancer. This article reviews the use and potential adverse events associated with these medications in frail elderly patients. This article also discusses the effects of the different antidepressants and antipsychotics on weight gain and appetite.

Abstract
Cognitive dysfunction is common in older persons suffering from a major depression. However, the degree to which this dysfunction is reversible with successful treatment of the depression remains uncertain. The present study examined the effects that treatment (randomized double-blind design) with either an SSRI (paroxetine) or a tricyclic antidepressant (nortriptyline) had on cognition in older depressed patients. The patients' performance was compared to that of a group of normal controls of similar age and education. Patients and controls were administered measures of working memory, information-processing speed, episodic memory and attention five times over the course of a 12 week trial. At baseline, the patients performed more poorly than the elderly controls on all cognitive measures. While the patients' performance did improve over the course of their treatment, the magnitude of this improvement did not exceed that produced in the elderly controls by practice alone. The same pattern of results was evident in both intent-to-treat and responder analyses. Thus, there was no evidence that the depressed patients' cognitive performance normalized after response to antidepressant therapy. Neither the patients' age at onset nor their baseline level of cognitive functioning influenced the amount by which their performance improved over the 12 week trial. There was no difference between paroxetine and nortriptyline in the amount of cognitive change associated with treatment. The present results suggest that cognitive dysfunction persists in older depressed patients even after their mood disorder has responded to antidepressant medications.

Abstract
UNLABELLED Sertraline is a selective serotonin reuptake inhibitor (SSRI) with well established antidepressant and anxiolytic activity. Results from several well designed trials show that sertraline (50 to 200 mg/day) is effective in the treatment of major depressive disorder in elderly patients (> or =60 years of age). Primary endpoints in most studies included the Hamilton Depression Rating Scale (HDRS), Clinical Global Impression (CGI) score and the Montgomery-Asberg Depression Rating Scale (MADRS). Sertraline was significantly more effective than placebo, and was as effective as fluoxetine, nortriptyline and imipramine in elderly patients. During one trial, amitriptyline was significantly more effective than sertraline [mean reduction from baseline on one of six primary outcomes (HDRS)], although no quantitative data were provided. Subgroup analysis of data from a randomised, double-blind trial in elderly patients with major depressive disorder suggests that vascular morbidity, diabetes mellitus or arthritis does not affect the antidepressant effect of sertraline. Secondary endpoints from these clinical trials suggest that sertraline has significant benefits over nortriptyline in terms of quality of life. In addition, significant differences favouring sertraline in comparison with nortriptyline and fluoxetine have been recorded for a number of cognitive functioning parameters. Sertraline is generally well tolerated in elderly patients with major depressive disorder, and lacks the marked anticholinergic effects that characterise the adverse event profiles of tricyclic antidepressants (TCAs). The most frequently reported adverse events in patients aged > or =60 years with major depressive disorder receiving sertraline 50 to 150 mg/day were dry mouth, headache, diarrhoea, nausea, insomnia, somnolence, constipation, dizziness, sweating and taste abnormalities. The tolerability profile of sertraline is generally similar in younger and elderly patients. Sertraline has a low potential for drug interactions at the level of the cytochrome P450 enzyme system. In addition, no dosage adjustments are warranted for elderly patients solely based on age. CONCLUSION Sertraline is an effective and well tolerated antidepressant for the treatment of major depressive disorder in patients aged > or =60 years. Since elderly patients are particularly prone to the anticholinergic effects of TCAs as a class, SSRIs such as sertraline are likely to be a better choice for the treatment of major depressive disorder in this age group. In addition, sertraline may have advantages over the SSRIs paroxetine, fluoxetine and fluvoxamine in elderly patients because of the drug's comparatively low potential for drug interactions, which is of importance in patient groups such as the elderly who are likely to receive more than one drug regimen.

Abstract
A computer-based literature search of all antidepressant and electroconvulsive therapy (ECT) treatment studies published between 1995 and September 2001 was conducted. In addition, a review of published chapters, review articles, and metaanalyses was also conducted. Articles were categorized into those reporting comparative studies, those in which the therapeutic agent was not compared with another, articles about ECT, and review articles. These recent publications support the conclusions from prior reviews that antidepressants and ECT are effective and safe treatments for depressed elderly patients. Differences in efficacy and side effects appear to be slight among the various types of antidepressants. Research studies of depressed elderly increased markedly since 1995 compared with all previous years although more studies are still necessary.

Abstract
The present study tests the activity of nootropic drugs in a behavioral test linked to depression. This test measures the reduction of submissive behavior in a competition test as the relative success of two food-restricted rats to gain access to a feeder. Nootropic drugs tested include piracetam (2-oxo-1-pyrrolidineacetamide), aniracetam (1-(4-methoxybenzoyl)-2-pyrrolidinone), the Ampakine, Ampalex, 1-(quinoxalin-6-ylcarbonyl)piperidine, and analogs were compared to the antidepressants, fluoxetine ((+/-)-N-methyl-gamma-(4-[trifluoromethyl]phenoxy)-benzenepropanamine) and desimpramine (5H-dibenz[b,f]azepine-5-propanamine, 10,11-dihydro-N-methyl-, monohydrochloride), while the anxiolytic diazepam (7-chloro-1-methyl-5-phenyl-3H-1,4-benzodiazepin-2(1H)-one) served as a control. Drugs were given intraperitoneally for 3 weeks. The antidepressant and nootropic drugs reduced submissive behavior over time. The effect was dose dependent as measured for fluoxetine and Ampakines. The reduction of submissive behavior by Ampakines gradually faded after cessation of treatment and had a more rapid onset of activity (during the 1st week of treatment) than fluoxetine (after 2 weeks). The results suggest that Ampakines may have antidepressant activity. The potential of depression treatment with memory-enhancing drugs is hypothesized and the link between cognition and depression is discussed.

Abstract
INTRODUCTION Bupropion immediate release (IR) and bupropion sustained release (SR) are frequently used to treat geriatric depression, as they have few cardiovascular, gastrointestinal and sexual adverse effects. We sought to examine the efficacy and dosing patterns of bupropion in a naturalistic cohort of elderly subjects with major depression (MD). METHODS 31 elderly ( > 60 years) patients with unipolar MD (DSM-IV) who were enrolled in Duke's Mental Health Clinical Research Center for the Study of Depression in Later Life were prescribed bupropion SR or IR, alone or in combination with other antidepressant agents, for 12 weeks. Montgomery-Asberg depression rating scale (MADRS) scores and clinical global impression (CGI) severity scores were used to define response. RESULTS 74% (23/31) of the sample were responders (MADRS < 15) and 53% (16/30) achieved a partial (CGI = 2) or complete (CGI = 1) remission of MD at week 12. Among patients treated with bupropion SR monotherapy, the mean (range) maximal daily dose achieved was 240 mg (150-400 mg). Among those treated with bupropion IR, the mean (range) maximum daily dose achieved was 258 mg (150-450 mg). In subjects on monotherapy, 67% (10/15) of MD subjects were responders (MADRS < 15) and 50% (7/14) achieved full or partial remission. Response rates did not differ statistically among those with high and low medical comorbidity. CONCLUSIONS In this naturalistic 12-week study, geriatric MD patients with high and low medical comorbidity responded well to bupropion and bupropion SR. In elderly patients, four to eight week acute treatment periods may be insufficient. Our findings suggest that nearly 50% of elderly depressed subjects at a tertiary center may need combination therapy over the course of their illness. Controlled randomized studies to establish the long-term efficacy and optimal dose of the newer antidepressants in geriatric depression are urgently needed.

Abstract
Research on treatment-resistant depression in the elderly has been limited, and recommendations for clinical management have often been extrapolated from studies using nongeriatric patients. This report describes a series of 10 elderly patients with refractory depression who were treated with nortriptyline after failing to respond to an adequate trial of a serotonin reuptake inhibitor. Seven (70%) of the patients responded to the addition or substitution of nortriptyline. All seven of the responders have remained on nortriptyline for maintenance therapy, none of whom have experienced recurrence of their depression after an average treatment duration of 1 year. Response to nortriptyline occurred in about 4 weeks in most patients. The mean daily dose of nortriptyline was 54 mg, and the mean plasma level was 97 ng/mL. Minor side effects occurred in three patients. No patients developed significant electrocardiogram changes. Nortriptyline, possibly due to its different mechanism of action, may be effective as either an adjunctive or replacement antidepressant in some cases of geriatric depression that are resistant to serotonin reuptake inhibitors.

Abstract
OBJECTIVE The aim of this single-blind study was to examine the efficacy and tolerability of citalopram compared to nortriptyline in moderate to severe major depressive patients aged 60 years or over. METHOD In- and out-patients (N=58) with unipolar major depression were randomized to 12-week flexible dose treatment with nortriptyline or citalopram. RESULTS No significant differences between the number of drop-outs in either group were observed, but the autonomic side-effects were significantly higher for nortriptyline than for citalopram. A significantly higher remission rate to nortriptyline than to citalopram was demonstrated, particularly if severe patients (endogenous or psychotic patients) were assessed. CONCLUSION The remission rate to a therapeutic plasma level of nortriptyline appears to be higher than the remission rate to a standard dose of citalopram in a group of elderly major depressed patients, especially those with endogenous or psychotic features. On the other hand, citalopram appears to be better tolerated.

Abstract
The naphthylamine derivative sertraline is a potent and selective inhibitor of serotonin reuptake into presynaptic terminals. Sertraline has a linear pharmacokinetic profile and a half-life of about 26 h. Its major metabolite, desmethylsertraline does not appear to inhibit serotonin reuptake. Sertraline mildly inhibits the CYP2D6 isoform of the cytochrome P450 system but has little effect on CYP1A2, CYP3A3/4, CYP2C9, or CYP2C19. It is, however, highly protein bound and may alter blood levels of other highly protein bound agents. Sertraline is a widely used serotonin reuptake inhibitor that has been shown to have both antidepressant and antianxiety effects. Many clinical trials have demonstrated its efficacy in depression compared with both placebo and other antidepressant drugs. Its efficacy has also been demonstrated in randomized, controlled trials of patients with obsessive-compulsive disorder, panic disorder, social phobia, and premenstrual dysphoric disorder. In short-term, open-label studies it has appeared efficacious and tolerable in children and adolescents and in the elderly, and data are positive for its use in pregnant or lactating women. Typical side effects include gastrointestinal and central nervous system effects as well as treatment-emergent sexual dysfunction; withdrawal reactions may be associated with abrupt discontinuation of the agent. The safety profile of sertraline in overdose is very favorable. Sertraline's efficacy for both mood and anxiety disorders, relatively weak effect on the cytochrome P450 system, and tolerability profile and safety in overdose are factors that contribute to make it a first-line agent for treatment in both primary and tertiary care settings.

CONTEXT Most double-blind studies of efficacy and tolerability of sertraline as compared to tricyclics in the treatment of late-life major depression have used amitriptyline as a standard, leading to the inevitable conclusion that the former drug is better tolerated than the latter, with both being equally efficacious. OBJECTIVE To compare the antidepressant efficacy and tolerability of sertraline (50 mg/day) and imipramine (150 mg/day) in the first 6 weeks of the treatment of major depression in the elderly. DESIGN A randomized double-blind parallel study with 6 weeks of follow-up. SETTING The psychogeriatric clinic at the Institute of Psychiatry, Hospital das Clínicas, Faculty of Medicine of the University of São Paulo. PARTICIPANTS 55 severe and moderately depressed non-demented outpatients aged 60 years or more. INTERVENTION Patients were assigned to sertraline 50 mg/day or imipramine 150 mg/day. MAIN MEASUREMENTS CAMDEX interview. Psychiatric diagnosis followed the guidelines for "Major Depressive Episode" according to DSM-IV criteria. Severity of symptoms was evaluated using the "CGI" and "MADRS" scales. Cognitive state was assessed using the Mini-Mental State Examination. Side effects were assessed using the "Safetee-Up" schedule. RESULTS Both groups had a significant decrease in depressive symptoms according to the MADRS scores after 6 weeks of treatment (P = 0.01). No significant differences between groups were detected regarding treatment outcome (t = 0.4; P = 0.7). Although the dropout rate was greater in the imipramine group, the overall tolerability among patients who completed the 6-week trial was similar in both test groups. CONCLUSIONS Both sertraline and imipramine exhibited good efficacy and an acceptable side-effect profile for elderly depressed patients after 6 weeks of antidepressant treatment.

Abstract
Using data from a larger 12-week clinical trial, the authors evaluated the comparative efficacy and safety of sertraline (n=42) and fluoxetine (n=33) in patients over age 70 with a diagnosis of major depressive disorder. Similar improvement on measures of depression, including remission of depressive symptoms, was evident, although significantly more sertraline-treated patients achieved a criterion clinical response. Significantly greater improvement for the sertraline group was apparent on the Digit Symbol Substitution Test, but not on two other measures of cognitive functioning. Although there was no difference in the rate of adverse events experienced, fluoxetine-treated patients lost significantly more body weight over the 12-week trial than did sertraline-treated patients, whereas the latter group exhibited significantly more "shaking.
