Depression is a state of depressed mood characterized by feelings of sadness, despair, and discouragement. Depression ranges from normal feelings of "the blues" through dysthymia to major depression. Endogenous depression has been identified with a specific symptom complex: psychomotor retardation, early morning awakening, weight loss, excessive guilt, and lack of reactivity to the environment. Reactive depression is precipitated by a stressful life event. In the field of depression, we found an overlapping activity between psychiatry and neurootology. Our sample comprises 134 patients (53 [39.55%] male, 81 [60.45%] female) who were classified either by psychiatrists or by neurologists as suffering from depression. By evaluating our neurootological history data bank (Neurootological Data Evaluation-Claussen [NODEC]) as regards 6 important vertigo symptoms, we found that patients presented with a frequency of 2.10 signs per patient. When we extended the list to 11 vertigo and nausea signs, we found 2.93 signs per patients. All patients underwent an objective and quantitative neurootometric analysis. The following rates of abnormal findings were observed: butterfly calorigram of polygraphic electronystagmography, 69.40%; stepping craniocorpograms, 69.40%; and bone-conduction pure-tone audiometry of the right ear, 28.36%, and of the left ear, 36.57%.

This paper reviews the literature on health-related quality of life (Hr-QoL) and depressive disorders, and the relationship between them, in patients with Parkinson's disease (PD). PD is associated with reduced Hr-QoL, including motor and non-motor physical consequences of the disease, emotional well-being and social functioning. While this effect is greater in advanced disease stages, there is no close relationship between disease duration and impact on quality of life, and the relationship between clinical rating scales and Hr-QoL scores is only moderate. On the other hand, presence and severity of depression in PD strongly correlates with Hr-QoL scores, and a number of studies have reported depression as the main determinant of poor HR-QoL scores. Despite being the main determinant of poor Hr-QoL and being recognized as an important problem by clinicians, until recently depression in PD has received relatively little attention in research studies. It is known that depression and anxiety occur more frequently in PD than in controls. Depression occurs in a bimodal pattern in PD, with increased rates at the onset and a later peak in advanced disease. Both anxiety and depression can also occur before the first motor symptoms of PD and predate the diagnosis of PD, indicating that these co-morbidities are manifestations of the underlying disease process of PD. Imaging studies have demonstrated abnormalities of dopaminergic, noradrenergic and serotonergic functioning with some correlation with severity of depression. The overall relationship between disease severity and rate of depression (except for off-period related depression) is poor, suggesting that nigrostriatal dysfunction alone is not sufficient to explain depressive symptoms in PD. Other factors are likely to contribute to occurrence and severity of depression in PD, either due to extrastriatal pathology or due to psychological and environmental factors leading to reactive depression. Thus, it is likely that depression in PD is multifactorial. The investigation of depression in PD is complicated by diagnostic difficulties in measuring and diagnosing depression in patients with PD due to the considerable overlap between symptoms of PD and depression. While a number of treatment approaches have been suggested, double-blind randomized controlled trials to demonstrate improvement of depression and overall Hr-QoL in PD are warranted.

There is strong evidence that depression involves alterations in multiple aspects of immunity that may contribute to the development or exacerbation of a number of medical disorders and also may play a role in the pathophysiology of depressive symptoms. Accordingly, aggressive management of depressive disorders in medically ill populations or individuals at risk for disease may improve disease outcome or prevent disease development. On the other hand, in light of data suggesting that immune processes may interact with the pathophysiologic pathways known to contribute to depression, novel approaches to the treatment of depression may target relevant aspects of the immune response. Taken together, the data provide compelling evidence that a psychoimmunologic frame of reference may have profound implications regarding the consequences and treatment of depression. In addition, this approach may be used to investigate the possibility that peripheral and central production of cytokines may account for neuropsychiatric symptoms in inflammatory diseases. This article summarizes evidence for a cytokine-mediated pathogenesis of depression and fatigue in MS. The effects of central inflammatory processes may account for some of the behavioral symptoms seen in patients who have MS that cannot be explained by psychosocial factors or CNS damage. This immune-mediated hypothesis is supported by indirect evidence from experimental and clinical studies of the effect of cytokines on behavior, which have found that both peripheral and central cytokines may cause depressive symptoms. Emerging clinical data from patients who have MS support an association of central inflammation (as measured by MRI) and inflammatory markers with depressive symptoms and fatigue. Based on the literature reviewed in this article, subtypes of MS fatigue and depression may exist that are caused by different pathogenetic mechanisms, including inflammation and CNS damage as well as psychosocial factors or predisposition. The existence of these subtypes could have important clinical implications. For example, an inflammatory depression may require different therapeutic approaches than a reactive depression in MS. Future research should aim to characterize these subtypes better with the goal of optimizing treatment.

The aim of this study was to establish types of psychological reactions and conditions in patients with lower-extremity amputations. Apart from using psychological interviews, detection was performed using psychometric tests: Minnesota Multiphasic Personality Inventory and Beck Depression Inventory. Psychometric parameters were analyzed in a group of 20 examinees treated at the Medical Rehabilitation Clinic in Novi Sad. Out of the whole sample, 45% of patients presented with adaptive reactions to amputation and consequent disability, whereas 55% presented with maladaptive responses. The registered psychopathological symptoms included nosologic categories: reaction to stressful events and adjustment disorder (predominantly affecting other emotions; mixed disorder of conduct and emotions; prolonged depressive reaction) and dysthymia. When working with lower-extremity amputees, apart from adaptive, nonpathological forms of behavior, one also encounters maladaptive responses with predomination of mood disorders due to severe somatic stress.

In the early 1980s, researchers studying osteoporosis noted that depression was one of the major negative consequences of bone loss and fractures. These researchers believed that osteoporosis and fractures occurred first, causing a reactive depression. Meanwhile, a similar but distinct psychiatry literature noted that osteoporosis or bone loss appeared to be an undesirable consequence of major depression. Here, depression was seen as the causal factor, and osteoporosis was the outcome. The psychiatric perspective is more biological, based on the presence of hypercorticoidism in depressed individuals. Those who believe that osteoporosis leads to depression point out that depression is a consequence of many chronic illnesses. Regardless of the correct causal order, the strong positive relationship between osteoporosis and depression merits further clinical and research attention in the future.

Amyotrophic lateral sclerosis is a devastating disorder for which the psychological consequences of both the diagnosis announcement and the evolution of paralysis not only concern the patient but also his family. The role of the psychologist is to develop an individualized follow up considering the patient in his globality. The first consultation is, ideally, initiated after a medical consultation explaining the importance of the psychological area in ALS patient care. The psychological follow up will consist in an empathic listening of history and problems. Information will also be given to the patient by the psychologist who's role should not be only passive. When talking about "globality" of the psychological intervention for a given patient, his family takes a determinant place. The psychologist should be able to establish a contact with the family members concerned by the daily support to the patient. The psychological processes through which a patient will evolve should be explained to the family. Depression frequently affects family members, and a specific follow up in those cases has to be undertaken as soon as possible. Such a depressive reaction may also take place after death and a psychological follow up do not end after the death of a patient. The role of a psychologist in ALS care ideally takes places in the context of a multidisciplinary team such as a motoneuron clinic now largely available in our country. The burden of care is frequently heavy both for the family and the team of professional carers into and outside the hospital. The psychologist has a role of mediation between those persons, facilitating verbal exchanges, paying attention to specific difficulties and maintaining a fruitful exchange between the carers, the patient and his family. More prospectively, the psychologist also has a pedagogic role for the carers explaining psychological processes and giving clues for a constructive relationship between the patient and his family and also between this patient and his carers.

The relationship between depression and dementia in the elderly has been widely investigated, but the real interplay between these variables is still not clear. This observational study highlights the influence of some basic variables, such as sex and age, in the development of dementia and major depression. It shows (i) the importance of sex in the age of onset of depression and dementia, (ii) the presence of two types of depressive syndrome, the first linked to the development of dementia, the second as reactive depression; (iii) the need for more attention to depressive symptoms in young-elderly men.

Clinically, depressive patients are increasing. It is very important but difficult to differentiate pathological depressive state from normal depressive reaction. In order to diagnose pathological depressive state (i.e. depression) and assess the severity, several diagnostic criteria and assessment scales for depression are available though most of them are provisional with limitations. In this review, Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision(DSM-IV-TR), Hamilton Rating Scale for Depression (HAM-D), and Montgomery-Asberg Depression Rating Scale (MADRS) are introduced and discussed. DSM-IV-TR is used for diagnosis and severity assessment of depression whereas HAM-D and MADRS can be used for only severity assessment.

This paper reviews concepts of depression, including history and classification. The original broad concept of melancholia included all forms of quiet insanity. The term depression began to appear in the nineteenth century, as did the modern concept of affective disorders, with the core disturbance now viewed as one of mood. The 1980s saw the introduction of defined criteria into official diagnostic schemes. The modern separation into unipolar and bipolar disorder was introduced following empirical research by Angst and Perris in the 1960s. The partially overlapping distinctions between psychotic and neurotic depression, and between endogenous and reactive depression, started to generate debate in the 1920s, with considerable multivariate research in the 1960s. The symptom element in endogenous depression currently survives in melancholia or somatic syndrome. Life stress is common in various depressive pictures. Dysthymia, a valuable diagnosis, represents a form of what was regarded earlier as neurotic depression. Other subtypes are also discussed.

Different types of depression in patients who survived cerebral stroke and their influence on the rehabilitation process were studied. One hundred and fifteen patients were examined. The clinical heterogeneity of post-stroke depression was shown. A clinical analysis allowed to find different nosological and psychopathological forms of depressive disorders. Two main nosological forms of depression--reactive and endoreactive--were found. The liability to affective disorders exerts the influence on the development of depression; reactive depression is related with more severe functional damage. Depression, in particular reactive one, has an unfavorable effect on the rehabilitation of neurological deficit and ability to self-service.
