Diagnostic conversion from depression to bipolar disorders: results of a long-term prospective study of hospital admissions.

OBJECTIVES: To analyse the time course and some risk factors for a diagnostic change from major depression to bipolar disorders (BP) over an average of 20 years from the onset of the disorders. METHODS: Patients (406) with major mood disorders hospitalised at some time between 1959 and 1963 were followed-up until 1985. The analysis also included the course prior to hospitalisation. Survival analyses and Cox regression models were applied. RESULTS: A diagnostic change from depression to bipolar I occurred in about 1% of the patients per year and to bipolar II disorders in about 0.5% per year. Risk factors for a change from depression to BP-I disorder were male sex and an early onset of the disorder; risk factors for a change from depression to BP-II disorder were female sex, a later onset of the disorder and a positive family history of mania. CONCLUSIONS: Across the entire lifetime, every new episode of depression brings a new risk for mania; more than half of our severe mood disorder cases became bipolars. The risk of depression developing into bipolar disorder remains constant lifelong. LIMITATIONS: The diagnostic classification of ICD-9 met RDC criteria for bipolar disorder in only 90% of cases. Part of the data collected in retrospect may be less reliable; the prospective data were only collected every 5 years from 1965 to 1985 using multiple sources; mild manifestations between the follow-ups may have been partially missed. The sample of subsequent hospital admissions for major depression and mania represents a severe group of patients and generalisations to ambulatory cases may not be possible. Not all risk factors for diagnostic conversion described in the literature could be assessed in this study.

Single spies and battalions: the clinical epidemiology of mental disorders.

Clinical epidemiology, a term that has been variously defined, is used here to refer to a discipline which, commencing with examination and diagnosis of the individual patient who presents in medical practice, proceeds to study the occurrence of similar, possibly connected cases in the local community, and in so doing may provide hypotheses for population-based studies of disease and its risk factors. While the relevance of this discipline to the modern practice of clinical psychiatry remains largely unexplored, its importance in the search for causes of mental disorder is attested by many instances, both historical and more recent, in which the spread or clustering of psychiatric syndromes in populations could be related to nutritional deficiency, infectious disease, the presence of environmental neurotoxins, the social communication of psychopathology or the transmission of abnormal, harmful behaviour patterns within family groups. Observations made in clinical practice have repeatedly served as the starting point for epidemiological investigation of mental disorders, while conversely epidemiological findings have influenced clinical thinking about their classification, diagnosis, prognosis and morbid risk. A review of the relevant literature underlines the need for a keener awareness of environmental risk factors and a fundamentally epidemiological frame of reference in trying to grapple with the aetiological problems of mental disorder.

Homozygosity mapping of Hallervorden-Spatz syndrome to chromosome 20p12.3-p13.

Hallervorden-Spatz syndrome (HSS) (OMIM #234200) is a rare, autosomal recessive neurode-generative disorder with brain iron accumulation as a prominent finding. Clinical features include extrapyramidal dysfunction, onset in childhood, and a relentlessly progressive course. Histologic study reveals massive iron deposits in the basal ganglia. Systemic and cerebrospinal fluid iron levels are normal, as are plasma levels of ferritin, transferrin and ceruloplasmin. Conversely, in disorders of systemic iron overload, such as haemochromatosis, brain iron is not increased, which suggests that fundamental differences exist between brain and systemic iron metabolism and transport. In normal brain, non-haem iron accumulates regionally and is highest in basal ganglia. Pathologic brain iron accumulation is seen in common disorders, including Parkinson's disease, Alzheimer's disease and Huntington disease. In order to gain insight into normal and abnormal brain iron transport, metabolism and function, our approach was to map the gene for HSS. A primary genome scan was performed using samples from a large, consanguineous family (HS1) (see Fig. 1). While this family was immensely powerful for mapping, the region demonstrating homozygosity in all affected members spans only 4 cM, requiring very close markers in order to detect linkage. The HSS gene maps to an interval flanked by D20S906 and D20S116 on chromosome 20p12.3-p13. Linkage was confirmed in nine additional families of diverse ethnic backgrounds.

A video review of the diagnosis of psychogenic gait: appendix and commentary.

The gait and other clinical features of 22 patients presenting to our hospital over the last 10 years are shown on video. In 12 patients, a diagnosis of psychogenic gait was made; in the remainder, the gait abnormality was the result of a neurologic disease. Psychogenic gaits are compared and contrasted with "organic" gaits. In one patient, the psychogenic gait occurred in the setting of a neurologic disease. The "traditional" approach to psychogenic gait, attempting to exclude underlying neurologic and psychiatric disease and seeking evidence for primary and secondary gain, was found to be of limited value. More useful were the features of the gait itself, in particular, exaggerated effort, extreme slowness, variability throughout the day, unusual or uneconomic postures, collapses, convulsive tremors, and distractibility; certain aspects of the history were also helpful. A list of comments is provided. The diagnosis of psychogenic gait, particularly in the elderly, remains fraught with hazard, and a balance has to be sought between subjecting an anxious patient to needless investigations and yet not losing sight of the fact that the patient may be elaborating on symptoms of genuine disease. The bizarre gait of some neurologic disorders, particularly dystonia and chorea, may be a pitfall for the unwary.

Somatoform disorders in neurological practice.

PURPOSE OF REVIEW: Patients with medically unexplained symptoms continue to intrigue, fascinate and frustrate clinicians. They are common in general medicine and often present with apparent neurological disorder. This review aims to provide insight into the recent literature that has sought to clarify epidemiology, diagnostic issues, aetiologic understanding and treatment of patients with psychogenic disorders who usually first present to neurologists. RECENT FINDINGS: Somatoform disorders are common in neurological practice. A number of papers have addressed issues of epidemiology and identified that medically unexplained symptoms in neurological populations are higher than originally thought. A number of recent review papers have served to summarize areas of considerable information (e.g. treatments) and areas of rapid growth in knowledge (e.g. neuroimaging). Studies investigating the role of psychological factors are well represented and clarify our psychopathological understanding of somatoform disorders in patients presenting to neurologists. Treatment studies are few and continue to be limited by population sizes and study designs. SUMMARY: Somatoform disorders are common in neurological populations. Comorbidity related to somatoform disorders with known organic neurological conditions requires further study. On account of the limitations of treatment studies, evidence-based clinical management of these patients is awaited.

Psychiatric diseases presenting as infectious diseases.

Although many psychiatric diseases have somatic manifestations, some focus on fears or delusions of infection. When a patient with a psychiatric basis for an apparent infection presents to an infectious disease physician, the physician may find the problem confusing, amusing, and ultimately frustrating until the psychiatric basis for disease is recognized. Some of these psychiatric disorders can be treated and controlled with medication and psychotherapy, although patients may resist psychiatric referral. This article reviews examples of psychiatric disorders in patients who present to the infectious disease physician, including factitious infection, malingering, obsessive compulsive disorder, phobias, veneroneuroses, somatization disorders, and delusional infection. The role that physicians play in amplifying these disorders is reviewed. Strategies for referral to psychiatric services are also discussed. Patients with a psychiatric disease are seen in infectious disease practices more commonly than physicians realize.

Complex partial and pseudoseizure disorders.

The differentiation of ictal and nonictal seizure disorders is difficult, particularly in patients suffering from partial seizures with complex symptomatology. The authors state that observation of a patient's habitual seizure during EEG recording is the ideal diagnostic tool and describe their method of seizure activation with sphenoidal electrodes and simultaneous audiovisual monitoring. They emphasize the necessity for early, aggressive treatment of both ictal and nonictal seizure disorders, point out risks to the patient if the incorrect diagnosis is made, and urge further cooperation between psychiatrists and neurologists in this borderland area.

Psychogenic nonepileptic seizures.

Psychogenic nonepileptic seizures (NES) are commonly encountered in clinical practice, and they may pose difficult diagnostic problems. For appropriate evaluation and treatment of NES, a multidisciplinary team approach is needed; typically, a neurologist with expertise in epilepsy, a psychologist or psychiatrist, and a support staff should be involved. Psychogenic NES have no single initial clinical manifestation, and various etiologic factors may contribute to their development. Of importance, psychogenic NES are "real" seizures that may be as disabling as epileptic seizures. Most often, they occur on a subconscious level, and the patient may have no control over their occurrence. Precipitation or termination of a habitual seizure during video-electroencephalographic monitoring has often been used to distinguish NES from epileptic seizures, but the results can sometimes be misleading. Numerous additional diagnostic techniques can be used to assist in making the diagnosis. Treatment is based on the type of psychiatric disorder present. Favorable prognostic factors include being female and having an independent lifestyle, normal electroencephalographic findings, higher intelligence, and no prior psychotherapy.

A teenage girl with extreme tachypnea.

Dyspnea and tachypnea are common presenting complaints in an emergency department. Respiratory and cardiac causes are the most common etiology. Functional respiratory disorders should be considered in patients with atypical presentation to avoid extensive investigations. We describe an adolescent who presented to our emergency department with extreme tachypnea.

Psychiatric morbidity and psychodynamics of patients with convulsive pseudoseizures.

Forty-six female patients with pseudoseizures were compared with 50 female patients referred to a psychiatric outpatient clinic. Patients with convulsive pseudoseizures were more likely to be single and childless. An abnormal EEG was more frequently reported in patients with convulsive pseudoseizures, contributing to their earlier diagnosis of epilepsy. The defence mechanisms of patients with convulsive pseudoseizures using the Defense Mechanisms Inventory (DMI) were particularly characterized by higher scores on the 'reversal' scale and lower scores on the 'turning against self' scale. Mood disorders were more common in general psychiatric patients, while one-third of convulsive pseudoseizure patients did not complain of psychiatric symptoms.

Globus pharyngis, commonly associated with esophageal motility disorders.

OBJECTIVES: To evaluate the role of gastrointestinal and psychiatric etiology in globus sensation. METHODS: The study population consisted of 32 consecutive patients with globus sensation without dysphagia referred to the Department of Otorhinolaryngology in Helsinki University Hospital. Eleven patients were excluded from the study: two because of advanced age, one prisoner, and six patients refused further studies. Only two patients (6%) were found to have abnormal otorhinolaryngological status. These patients were also excluded from the study. Esophagogastroduodenoscopy, 24-h pH recording, esophageal manometry, and Bernstein acid perfusion test were carried out in 21 patients (13 females, eight males, mean age 49 yr). Psychiatric evaluation was done in 20 patients; one patient refused the psychiatric consultation. RESULTS: Abnormal endoscopy was found in 12/21 (57%) of the patients, with antral gastritis and hiatal hernia being the most common findings. Two patients had esophagitis. Sixty-seven percent demonstrated abnormalities in esophageal manometry, the most frequent finding being a nonspecific esophageal motility disorder (29%). pH monitoring was normal in 16/21 of patients (76%), whereas the Bernstein test showed positive results in 13/21 (62%). With DSM IIIR as the diagnostic tool, five of 20 patients (25%) received a psychiatric diagnosis. CONCLUSIONS: Globus sensation has a multiple etiology, and local reasons are rare but should first be ruled out. Abnormalities in esophageal motility are commonly found, and these patients seem to be sensitive to esophageal acidity. Esophageal manometry and ambulatory 24-h pH recording should be included in the evaluation of a globus patient. The number of psychiatric disorders does not differ from that in the general population. Treatment of globus sensation should be directed toward the abnormality found behind the symptom.

[Opinions on psychiatric diseases of the citizens of Novosibirsk: results of a representative study].

BACKGROUND: Citizens of Novosibirsk were questioned regarding their ideas about schizophrenia and depressive disorders, with one of the main concerns being a comparison with the ideas and attitudes of the German population. METHOD: In 2002, a representative survey (N = 745) was conducted among the adult population of Novosibirsk, using a fully structured interview that has been used in previous surveys in Germany. RESULTS: Symptoms of schizophrenia were more frequently identified as an indication of mental disorder than were depressive symptoms. Psychosocial stress and biological influences were similarly frequently seen as the cause of schizophrenia, with the former prevailing among the respondents in the case of depressive symptoms. Psychotherapy was most frequently recommended as a treatment measure, also for schizophrenia. Supposing that no treatment measures will be taken, respondents assessed the prognosis for both mental disorders negatively. Conversely, interviewees gave a positive treatment prognosis. DISCUSSION: Respondents from Germany and Novosibirsk showed similar beliefs, especially as regards the importance of biological influences and psychosocial stress and the assessment of psychotherapy as compared to psychopharmacology. However, German and Russian respondents also held differing views: a comparatively strong tendency of the Russian population to consider mental disorders as self-inflicted - an important finding that could shape future anti-stigma programs.

A study of 111 cases of globus hystericus.

Videofluorography (VFG) and manometry were used to evaluate 111 patients who were diagnosed with globus hystericus. Most of the globus patients were affected by functional diseases and the underlying pathology could be revealed by VFG in 73.9 per cent of the series and by manometry in 80.2 per cent. There were 10.8 per cent of the series in which VFG and manometry yieled normal findings. The most common abnormality determined by manometry was esophageal aperistalsis. The most common abnormality revealed by VFG was cricopharyngeal bar. VFG was sensitive for morphologic detection while manometry was sensitive for motility study. Functional disorders can result in morphologic abnormality and vice versa. Therefore, VFG and manometry complement each other and are invaluable tools in the investigation of globus patients.

Expressed emotion in the relatives of people with epileptic or nonepileptic seizures.

PURPOSE: This study investigated Expressed Emotion (EE) in relatives of people with epileptic or nonepileptic seizures (NES). METHODS: In a cross-sectional study, we used the Five-Minute Speech Sample to explore EE in the key relative of people with epilepsy (n = 36) and those with NESs (n = 21), as well as levels of anxiety and depression and use of coping strategies. RESULTS: A significantly greater proportion of relatives of NES than epilepsy patients were rated as high EE. Hostility was evident in more high-EE epilepsy than high-EE NES relatives, whereas emotional overinvolvement and positive relationship ratings tended to be more common in high-EE NES relatives. High- and low-EE epilepsy relatives used problem-focused as opposed to emotion-focused coping strategies significantly more than half the time. High EE and seizure frequency were not associated. Age at onset of the disorder was higher in epilepsy patients with high- than with low-EE relatives. CONCLUSIONS: Irrespective of etiology, carers for people with seizure disorders may find it hard to adjust to the difficulties these disorders create. Interventions that encourage problem-solving, reappraisals of "loss" and education regarding the causes of some of the patients' behavioral and mood problems seem likely to be beneficial.

Treatment outlines for the management of the somatoform disorders. The Quality Assurance Project.

The Quality Assurance Project is developing explicit and detailed treatment outlines for each of the major psychiatric disorders. Three sources of information are used: the treatment outcome literature, the opinions of a sample of practising psychiatrists and the views of a panel of nominated experts. The recommendations for the treatment of somatoform disorders were as follows: brief dynamic psychotherapy, family therapy and excellent medical consultation are the basis for the treatment of hypochondriasis. Limited long-term supportive psychotherapy and good medical consultation are important in somatization disorder. Symptom relief, psychotherapeutic support and meticulous collaboration with physicians are the keys to managing psychogenic pain disorder. Physiotherapy to improve physical functioning and patient education to facilitate the distinction between normal symptoms and abnormal illness behaviours are important in all three conditions. Neither the benzodiazepines nor behaviour therapy appear to be of use in these conditions.

[The ego and dysphonias].

Every psycho-affective disorder may be a factor of language constitution and communication disorders. The study of it, particularly in psychosis is a major sign for diagnosis. Linguistic troubles are correlate with mind perturbations and the psychotic language is symptomatic. The most suggestive example is schizophrenia. Rythm and sound stay, yet semantics and syntactics expressions are down.

Somatoform disorders: personality and the social matrix of somatic distress.

Personality traits that may contribute to somatization are reviewed. Negative affectivity is associated with high levels of both somatic and emotional distress. Agreeableness and conscientiousness may influence interactions with health care providers that lead to the failure of medical reassurance to reduce distress. Absorption may make individuals more liable to focus attention on symptoms and more vulnerable to suggestions that induce illness anxiety. More proximate influences on the selective amplification of somatic symptoms include repressive style, somatic attributional style, and alexithymia; however, data in support of these factors are scant. Most research on somatoform disorders confounds mechanisms of symptom production with factors that influence help seeking. Longitudinal community studies are needed to explore the interactions of personality with illness experience and the stigmatization of medically unexplained symptoms.

[What is dementia? 6. From physiological aging to dementia].

Many studies have been devoted to the cognitive changes associated with age, and several attempts have been made for their classification in order to distinguish normal from pathologic changes. In the last few years, a consensus has been reached to classify elderly people in three groups: a) cognitively normal subjects whose cognitive functions score in the range of those of healthy subjects paired according to age and educational level, presenting or not memory complaints; b) subjects with dementia; c) an intermediate group of subjects presenting a cognitive impairment not severe enough to meet the criteria for dementia. The term mild cognitive impairment (MCI) has been proposed to describe these subjects who are at high risk to progress to dementia in the years following the diagnosis. For the first time, MCI construct allows the recognition of the prementia phase of degenerative or vascular cerebral diseases progressing to dementia. However, the lack of clear operational diagnostic criteria and ambiguities about the signification of MCI make the interpretation of the results of studies devoted to this concept hazardous. From a practical point of view, the physician, when faced with a patient complaining of his\her memory, should answer two main questions. "How to recognize memory disorders resulting from incipient AD?" and "What is the signification of memory complaints not related to AD?" The semioloy of memory complaints and the qualitative aspects of the memory deficit allow the diagnosis of incipient AD with pretty good accuracy. Due to the location of the first lesions of AD in hippocampal regions, memory disturbances in AD are related to a deficit in memorization of new information in episodic memory. Conversely, memory disorders related to normal aging, depression, and degenerative or vascular brain lesions not involving hippocampus, are related to deficits in the processes of recall of previously memorized informations. Benign memory complaints have been considered to be linked to the decrease of memory performance, and defining a special group of normal elderly subjects. However, no direct relationship has been demonstrated between memory complaints and performance. In our opinion, all memory complaints are essentially related to psychoaffective disturbances, mainly anxiety, changes in identity and decrease of self-esteem associated with aging.
