Abstract
BACKGROUND The coronavirus disease emerged in 2019, spread in Turkey as all over the world rapidly. In this process, young people began to experience some mental problems due to the fear of contagion, as well as some changes in their lifestyles. AIMS In this study it is aimed to investigate anxiety and depression levels of medical school students and the factors associated with these mental problems. METHOD The forms were sent over the internet to the officials responsible for medical education at universities in various regions of Turkey. A total of 2,778 medical faculty students were included in the study. Students were asked to fill out the sociodemographic data form, the Patient Health Questionnaire - 9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7) Test. RESULTS Students' 67.3% were female and 31.7% were male. About 90.2% of the students in the PHQ-9 scale had depressive symptoms in the major depressive disorder (MDD) dimension, and 44.5% in the GAD-7 scale had moderate/severe anxiety symptoms. Gender, being a preclinical student, history of psychiatric treatment in the past, currently receiving psychiatric treatment, death of someone due to pandemic, economic and health situation, perception of mental health were found associated with MDD and Moderate/Severe Anxiety symptoms. Students with Anxiety and MDD reported significantly more anxiety about contamination and negative beliefs about precautions' sufficiency. CONCLUSIONS It was determined that medical school students in our country showed anxiety and depression at a remarkable level during the pandemic. Examining the underlying causes of these high rates will be beneficial in terms of taking precautions during the long-term pandemic. In literature, there are a limited number of studies on this subject in our country, we believe that our study will be useful in future studies to determine the underlying causes of mental illnesses and what can be done to help students.

Abstract
With a lifetime prevalence of approximately 17% anxiety disorders are among the most common mental disorders worldwide. The disease progression can take a chronic course leading to a considerable impairment of the affected person. The current medical classification list (ICD-10) by the World Health Organization differentiates between agoraphobia, social phobia, specific phobia, panic disorder and generalized anxiety disorder. The etiology is multicausal comprising an interaction of genetic and psychosocial factors. For treatment, psychotherapy, psychopharmacological treatment and a combination of both methods are eligible. Anxiety disorders are often associated with physical illness either as the causative factor or the consequence. In particular, anxiety has been identified as an independent risk factor for cardiovascular disease. Anxiety disorders associated with somatic diseases are often unrecognized, therefore an optimization of diagnostic and treatment strategies is necessary.

Abstract
BACKGROUND: Persons with aphasia often report feeling anxious when using language while communicating. While many patients, caregivers, clinicians and researchers would agree that language may be a stressor for persons with aphasia, systematic empirical studies of stress and/or anxiety in aphasia remain scarce. AIM: The aim of this paper is to review the existing literature discussing language as a stressor in aphasia, identify key issues, highlight important gaps, and propose a program for future study. In doing so, we hope to underscore the importance of understanding aspects of the emotional aftermath of aphasia, which plays a critical role in the process of recovery and rehabilitation. MAIN CONTRIBUTION: Post stroke emotional dysregulation in persons with chronic aphasia clearly has adverse effects for language performance and prospects of recovery. However, the specific role anxiety might play in aphasia has yet to be determined. As a starting point, we propose to view language in aphasia as a stressor, linked to an emotional state we term "linguistic anxiety." Specifically, a person with linguistic anxiety is one in whom the deliberate, effortful production of language involves anticipation of an error, with the imminence of linguistic failure serving as the threat. Since anticipation is psychologically linked to anxiety and also plays an important role in the allostatic system, we suggest that examining physiologic stress responses in persons with aphasia when they are asked to perform a linguistic task would be a productive tool for assessing the potential relation of stress to "linguistic anxiety." CONCLUSION: Exploring the putative relationship between anxiety and language in aphasia, through the study of physiologic stress responses, could establish a platform for investigating language changes in the brain in other clinical populations, such as in individuals with Alzheimer's disease or persons with post traumatic stress disorder, or even with healthy aging persons, in whom "linguistic anxiety" might be at work when they have trouble finding words.

Chronic low dose corticosterone exposure decreased hippocampal cell proliferation, volume and induced anxiety and depression like behaviours in mice. Eur J Pharmacol 2008; 583:115-27.

Abstract
A dysregulated hypothalamic-pituitary-adrenal axis (HPA) has been implicated in major depressive disorder and most commonly used animal models of depression have been shown to elevate circulating levels of plasma corticosterone. We have compared the effects of chronic and acute corticosterone administration on hippocampal cell proliferation (as measured by BrdU immunohistochemistry), hippocampal volume and the appearance of anxiety (light dark box) and depression (forced swim test) like behaviours in CD1 mice. We have also examined the effects of chronic administration of fluoxetine and imipramine on these parameters. Chronic (14 days) but not acute treatment with corticosterone resulted in reduced hippocampal cell proliferation and granule cell layer volume, these changes were prevented by co-administration of imipramine and fluoxetine. In contrast, acute and 7 day but not 14 or 21 day treatment with corticosterone gave rise to a "depressed" phenotype in the forced swim test. Mice treated for 14 days with corticosterone also developed an anxious phenotype in the light dark box but only upon repeated testing. The results presented here demonstrate that moderately elevated corticosterone for a prolonged period is sufficient to induce cellular changes in the hippocampus that are prevented by chronic administration of antidepressants.

Abstract
Eighty treatment-seeking adults age 60 or over with panic disorder, generalized anxiety disorder, and mixed anxiety states (generalized anxiety with panic attacks, panic disorder with secondary generalized anxiety) completed a clinical assessment and battery of self report measures. Several hypotheses were tested from the domains of distinguishing symptoms, associated features, and rates of comorbidity with other disorders. Greater between- than within-group variance was found on a subset of measures suggesting that the distinction between GAD and PD is generally valid in the older adult population. Higher scores on measures of sympathetic arousal, agoraphobic avoidance, and rates of comorbid somatization disorder and alcohol dependence distinguished those with PD from those with GAD. Higher scores on measures of depression and hostility, but not trait anxiety or worry, distinguished the GAD group. Results indicate that distinguishing features of GAD and PD in older treatment-seeking adults may be fewer and slightly different from those of younger adults.

Abstract
OBJECTIVE Diagnostic criteria and nosological boundaries of juvenile dysthymic disorder (DD) are under-researched. Two different sets of diagnostic criteria are still discussed in the DSM-IV, the first giving major weight to somatic and vegetative symptoms and the second, included in the appendix, to more affective and cognitive symptoms. The aim of this study was to describe prototypical symptomatology and comorbidity of DD, according to DSM-IV criteria, in a consecutive series of referred children and adolescents, as a function of age and sex. METHOD One hundred inpatients and outpatients (36 children and 64 adolescents, 57 males, 43 females, age range 7 to 18 years, mean age 13.3 years) received a diagnosis of DD without comorbid major depressive disorder (MDD), using historical information, the Diagnostic Interview for Children and Adolescents-Revised (DICA-R), and symptoms ratings according to the DSM-IV criteria. RESULTS Irritability, low self-esteem, fatigue or loss of energy, depressed mood, guilt, concentration difficulties, anhedonia, and hopelessness were present in more than 50% of subjects. Differences in symptomatic profile between male and female patients were not significant. Anxiety disorders were commonly comorbid with DD, mainly generalized anxiety disorder, simple phobias, and in prepuberal children, separation anxiety disorder. Externalizing disorders were reported in 35% of the patients, with higher prevalence in male patients. Adolescents showed more suicidal thoughts and anhedonia than children. CONCLUSIONS The clinical picture of early-onset DD we found, based entirely on a pure sample without current and past MDD, is not totally congruent with the diagnostic criteria according to DSM-IV. A more precise definition of the clinical picture may help early diagnosis and prevention of superimposed mental disorders.

Abstract
Estimation of comparative disease burden in epidemiological surveys is complicated by the fact that high comorbidities exist among many chronic conditions. The easiest way to take comorbidity into consideration is to distinguish between pure and comorbid conditions and to evaluate the incremental effects of comorbid conditions in prediction equations. This approach is illustrated here in an analysis of the effects of pure and comorbid major depression (MD) and generalized anxiety disorder (GAD) on a number of different measures of role impairment in the US National Comorbidity Survey (NCS) and the Mental Health Supplement to the Ontario (Canada) Health Survey (the Supplement). Pure MD and pure GAD were found to have roughly equal independent associations with role impairments. The incremental effects of having comorbid MD and GAD were found to vary depending on the outcome under investigation. The paper closes with a discussion of the methodological complexities associated with generalizing to comorbidities that involve rare conditions or more than two disorders.

Abstract
A few authors have described the clinical picture of dysthymia in groups of elderly patients and pointed out differences from literature reports of dysthymia in younger adults. The present study, an attempt to analyze age effects on clinical characteristics of dysthymia throughout a lifetime, was performed in a sample of 106 patients, all aged > or =18 years, who were diagnosed according to DSM-IV. The patients were evaluated using: (1) a semistructured interview to assess clinical features, family history and previous treatments; (2) the Hamilton Depression Rating Scale; (3) the Interview for Recent Life Events; and (4) the Structured Clinical Interview for DSM-IV Disorders. Statistical analysis with stepwise logistic regression revealed that age was positively related to concomitant medical illnesses and to the total score of recent life events, but negatively related to the presence of avoidant or dependent personality disorders. The data suggested different etiologic pathways in older and younger patients. Dysthymia appeared to be associated in younger adults with abnormalities of personality; in the elderly, with a history of health problems and life losses.

Abstract
BACKGROUND The variability in the clinical presentation of dysthymia has given rise to a rich debate in literature, and various hypotheses have been proposed. One is that the clinical presentation differs in relation to age at onset. The aim of the study was to evaluate differences in socio-demographic and clinical characteristics in a sample of patients with dysthymia (DSM-IV), in relation to age at onset. METHOD 84 consecutive outpatients with a diagnosis of dysthymia (DSM-IV) were studied. All subjects were evaluated by a semistructured clinical interview and the following rating scales: HAM-A, HAM-D, MADRS, Paykel's Interview for Recent Life Events. RESULTS 23.8% of the sample had early-onset (<21 yrs) dysthymia. Patients with early-onset disorder were significantly younger at the observation, more frequently female and single. They had a significantly longer duration of illness and in a significantly higher percentage had already received a specialist treatment before admission in the present trial. No differences in the frequency of symptoms were observed. A significantly higher percentage of patients with late-onset disease reported at least one stressful event in the year preceding the onset of dysthymia. A positive history of major depression was significantly more common among the early-onset group; social phobia, panic disorder and conversive disorder were also more frequent in this group. The late-onset patients frequently presented generalized anxiety disorder, substance abuse and somatization disorder. LIMITATION The study is retrospective and enrolls a limited number of cases. CONCLUSIONS The present study agrees with other reports on the differences in clinical presentation of dysthymia according to age at onset. Although they are not actually related to age at onset, some interesting findings emerged in the symptomatological characterization of the disorder, referring to the diagnostic criteria proposed in DSM-IV.

Abstract
We studied a group of patients with depression divided into subtypes of non-chronic major depression, chronic major depression, and pure dysthymia. The purpose of this study was to determine if clinical and family history factors separated these types of depression. We reviewed records from semi-structured clinical interviews and abstracted data regarding factors that might differentiate these three depressive subtypes. In general we found what might be predicted from the definitions of dysthymia versus major depression, that is, ratings for severity of depression were lower for dysthymic patients as compared to patients with non-chronic or chronic major depression. We also found lower ratings for social functioning (GASF) for dysthymic patients as compared to the other depressive subtypes. Our study does not provide data to sufficiently separate these three subtypes. However, in the course of reviewing the literature on this topic, very few studies have separated patients into these distinct depressive subtypes. Further studies are needed to indicate if these subtypes can be meaningfully separated.

Abstract
This review focuses on recent literature concerning dysthymia in the elderly population. Epidemiological data and clinical picture, diagnostic and therapeutic issues are evaluated and discussed. Although depressive syndromes are common in older patients, prevalence rates of dysthymia in the elderly are lower than in younger adults. This finding may be the consequence of the diagnostic criteria provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM) which are not specific for older adults. Other factors that complicate making diagnoses of dysthymia in older individuals are comorbid general conditions, cognitive deterioration and disorders, and frequent adverse life events (e.g. bereavement). The effects of these factors should be better defined to clarify whether elderly dysthymia is underestimated and if modified diagnostic criteria should be provided. A few researchers have identified a series of clinical features that are clearly different in the elderly and in young adult patients with dysthymia. These features are particularly related to the late onset and to the peculiar comorbidity of this disorder and suggest that dysthymia is a different disorder in the elderly. Drug treatment of depressive conditions in the elderly is currently based on new antidepressants [selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors, norepinephrine (noradrenaline) reuptake inhibitors, benzamides]. These agents have an improved adverse effect profile compared with some of the older agents. Moreover, very few systematic studies have been performed using these drugs in samples of older patients with dysthymia and available data do not allow conclusions on drug choice and dosage. Besides, no specific data are available concerning the psychotherapy of dysthymia in this age group. All these topics need to be further investigated in studies comparing the elderly with control groups of younger patients with dysthymia.

Abstract
OBJECTIVE Generalized anxiety disorder might be better conceptualized as a prodrome, residual, or severity marker of major depression or other comorbid disorders than as an independent diagnosis. The authors questioned whether generalized anxiety disorder itself is associated with role impairment or whether the impairment of patients with generalized anxiety disorder is due to depression or other comorbid disorders. METHOD The authors assessed data from the National Comorbidity Survey and the Midlife Development in the United States Survey for generalized anxiety disorder and major depression at 12 months by using the DSM-III-R criteria with modified versions of the Composite International Diagnostic Interview. RESULTS The prevalences of generalized anxiety disorder at 12 months were 3.1% and 3.3%, respectively, in the National Comorbidity Survey and the Midlife Development in the United States Survey; the prevalences of major depression at 12 months were 10.3% and 14.1%. The majority of respondents with generalized anxiety disorder at 12 months in the National Comorbidity Survey (58.1%) and the Midlife Development in the United States Survey (69.7%) also met the criteria for major depression at 12 months. Comparisons of respondents with one versus neither disorder showed that both disorders had statistically significant independent associations with impairment that were roughly equal in magnitude. These associations could not be explained by the other comorbid DSM-III-R disorders or by sociodemographic variables. CONCLUSIONS These results show that a substantial amount of generalized anxiety disorder occurs independently of major depression and that the role impairment of generalized anxiety disorder is comparable to that of major depression.

Abstract
There are few data on the clinical features of dysthymia among the community-dwelling elderly. Forty elderly individuals with dysthymic disorder were identified following screening in the community with GMS-AGECAT. A detailed clinical history was obtained and DSM-IV checklists and standardized scales were used, at a second interview. Comparisons were made with a group of 630 non-depressed elderly from the same community. Dysthymia was predominately of late onset (93%) and associated with a major stressor in 65% of cases. Comorbid axis 1 disorders were present in 15% of dysthymics and an axis 2 disorder in 10%. The dysthymic group had significantly higher degrees of physical impairment than the non-depressed elderly. The symptom profile demonstrated prominent anxiety and functional features. Eighty-three per cent of the elderly with dysthymia had presented to their GP with anxiety/depressive symptoms at some stage during the dysthymic disorder. The presentation of dysthymia in older people differs from that in earlier life. Late life dysthymia is less associated with axes 1 and 2 comorbidity but is associated with significant degrees of physical impairment. Dysthymia in older people presents to primary care, rather than specialist services, and interventions must be delivered at this level.

Abstract
BACKGROUND This study examined the validity of the early-late onset subtyping distinction in dysthymic disorder. METHODS Participants were 340 out-patients meeting DSM-III-R criteria for dysthymia and a concurrent major depressive episode (MDE). The sample was drawn from a 12-site double-blind randomized parallel group trial comparing the efficacy of sertraline and imipramine in the treatment of chronic depression. All patients received comprehensive evaluations using semi-structured interviews and rating scales. RESULTS 73% of the sample met criteria for the early-onset, and 27% for the late-onset, subtype. The early-onset patients had a significantly longer index MDE, significantly higher rates of personality disorders and lifetime substance use disorders, and a significantly greater proportion had a family history of mood disorder. The subgroups did not differ in symptom severity or functional impairment at baseline, nor in response to a 12-week trial of antidepressants. LIMITATIONS Further work is needed to extend these findings to dysthymic disorder without superimposed MDEs. CONCLUSIONS These results support the distinction between early-onset and late-onset dysthymic disorder.

Abstract
SummaryDysthymia is the last diagnostic label introduced after a series of precursors to describe a disorder whose nosological status has long been dubious. The results of published epidemiological, as well as clinical studies about its presentation, course and outcome partly support the validity of this construct — although their interpretation is limited by methodological difficulties: same prevalence in many locations in the world, always lower than that of major depression, somewhat specific clinical pattern, course and outcome.

Abstract
OBJECTIVE To examine the nature and conceptualization of generalized anxiety disorder (GAD) and chronic worry as well as data bearing on the validity of GAD as a distinct diagnosis. METHOD Narrative literature review. RESULTS Although a wealth of data have been obtained on the epidemiology, genetics, and nature of GAD, many important questions remain regarding the validity of current conceptual models of pathological worry and the discriminability of GAD from certain emotional disorders (for instance, mood disorders) and higher-order trait vulnerability dimensions (for example, negative affect). CONCLUSION Because the constituent features of GAD are salient to current conceptual models of emotional disorders (for example, models that implicate negative affect or worry/anxious apprehension as vulnerability factors), research on the nature of GAD and its associated features should provide important information on the pathogenesis, course, and co-occurrence of the entire range of anxiety and mood disorders.

Abstract
Spectral analysis of fluctuations in heart rate and blood pressure was employed to explore sympathetic and parasympathetic cardiovascular control mechanisms in relation to trait anxiety in major depressive disorder Sixteen drug-free female depressed patients were divided into two groups: those who were high on trait anxiety (HTA, n = 9) and those who were normal or low on trait anxiety (LTA, n = 7). In patients and age-matched female controls (n = 10), heart rate (HR), blood pressure (BP; Finapres device) and respiration were recorded during a period of supine rest (10 min), orthostatic challenge (60 degrees head-up tilting, 8 min), and post-orthostatic supine rest (8 min). Power spectra were calculated over the last 4 min of these three situations for HR, systolic BP, as well as for respiration. Spectral density was assessed for three frequency bands: low (0.02-0.06 Hz), mid (0.07-0.14 Hz) and high (0.15-0.50 Hz). Patients did not differ from controls during supine rest. During orthostatic challenge, HTA patients showed significantly more HR increase and suppression of high-frequency fluctuations of HR (suggesting stronger vagal inhibition) in comparison with the controls; this effect was accompanied by a significant increase in respiratory frequency. Both patients groups did not show the normal increase in mid-frequency band fluctuations of BP during orthostatic challenge, indicating reduced sympathetic activation. Low-frequency fluctuations of HR, as well as respiratory frequency during post-orthostatic supine rest of the HTA patients were significantly increased versus controls. This exploratory study indicates that trait anxiety may be a relevant factor when evaluating parasympathetic and sympathetic dysbalances in the state of a major depressive disorder.

Abstract
The DSM-IV Mood Disorders Field Trial addressed several issues concerning the relationship among major depression, dysthymia, recurrent brief depression, minor depression, and depressive personality disorder. The Mood Disorders Field Trial is a naturalistic, multisite study that investigated the diagnostic criteria for dysthymia, the reliability and validity of longitudinal course modifiers, the nosology of minor and recurrent brief depression, and the relationship between depressive personality disorder and dysthymia. Research on the nosology of chronic depressive disorders will, it is hoped, contribute to a better understanding of pathophysiology, etiology, and treatment. This article presents findings from the Field Trial as well as brief reviews of the other nine articles in this issue.

Abstract
The lists of associated symptoms included in the DSM-III, DSM-III-R, and DSM-IV criteria for dysthymic disorder have been criticized for lacking content and discriminant validity. The literature on the content and discriminant validity of dysthymic symptoms was reviewed and relevant data from the DSM-IV Mood Disorders Field Trial were presented. These data indicate that cognitive and social-motivational symptoms are much more characteristic of dysthymic disorder than are vegetative and psychomotor symptoms. In addition, subjects with major depressive disorder exhibit higher rates of most depressive symptoms than do subjects with dysthymic disorder, but there is little evidence of qualitative distinctions in symptomatology between these conditions. Finally, after taking course and exclusion criteria into account, variations in the symptom criteria do not have a major effect on case definition.

Abstract
The goal of this study is to examine different criteria for the diagnosis of dysthymic disorder (DD). Using a two-stage design, records of 37 subjects diagnosed with DSM-III-R DD were systematically reviewed. Seven of these patients met criteria except for having depression less than 50% of the time. The initial evaluation involved a comparison of the diagnostic assessments using symptom criteria of DSM-III-R and ICD-10, proposed DSM-IV criteria for DD, DSM-III-R major depressive disorder (MD) criteria, and the Columbia criteria for atypical depression (AD). A subsample of 16 subjects who were assessed at least twice several months apart was then extracted. Agreement between the assessments with the proposed DSM-IV symptom list was determined. In the initial assessment, all 37 subjects (100%) met DSM-III-R and ICD-10 criteria, proposed DSM-IV criteria for DD, and DSM-III-R MD criteria, with percentages of mean positive items on the four criteria being 77%, 84%, 89%, and 77%, respectively. In addition, nine subjects (24.3%) also met diagnostic criteria for AD. All 16 subjects (100%) of the subsample again met proposed DSM-IV criteria for DD when assessed 75 to 145 days after their initial assessment. Items with the highest agreement between each two assessments were pessimism and low self-esteem, whereas social withdrawal and decreased activity had lower agreement. The proposed DSM-IV criteria for DD had good sensitivity and reliability in assessing core symptoms of DD. The use of different criteria for DD is discussed.

Abstract
This paper reviews current evidence in support of dysthymia as a sub-affective disorder that precedes major affective episodes, often by more than a decade. In cases beginning in childhood or adolescence, dysthymia is associated with high familial rates of mood disorders, and a recurrent pattern of superimposed major depression. At least two trait-like markers, sleep electro-encephalographic and thyroid axis abnormalities-similar to those in major affective disorder-have been reported. These data indicate a common pathophysiological substrate for both dysthymia and major depressive illness. All classes of antidepressants-most recently the serotonin re-uptake and the reversible MAO inhibitors-have been shown to be effective. Dysthymia was fairly recently included in the US(DSM) and WHO(ICD) classifications of mental disorders, because it characterises a prevalent clinical presentation of depression in both psychiatric and general medical settings. Patients given this diagnosis, instead of presenting with acute or full-blown episodes, often complain of low-grade chronic affective malaise for as long as they remember, yet without clinically observable signs of depression. As a result, questions have been raised about its validity, but from fundamentally opposite positions: (i) Is dysthymia better conceptualised as a personality (or neurotic) rather than mood disorder? (ii) Can dysthymia be distinguished from major depressive illness? This paper examines these and related questions along both clinical and external validating strategies, and in particular, the more recent accumulated evidence in support of the utility of the concept of dysthymia.

Abstract
Eighty-one outpatients with bipolar disorder (BD) were grouped by SADS anxiety symptom scores (high vs. low) or diagnosis of generalized anxiety disorder, and/or panic disorder. BD patients with high anxiety scores were more likely to have suicidal behaviour (44% vs. 19%), alcohol abuse (28% vs. 6%), cyclothymia (44% vs. 21%) and an anxiety disorder (56% vs. 25%) with a trend toward lithium non-responsiveness. Diagnosis of an anxiety disorder was related only to high anxiety and lower GAS scores. Thus, anxiety may have similar clinical relevance in BD as it does in unipolar patients.
