Manic-depressive illness in children: an early twentieth-century view by Theodor Ziehen (1862-1950). Introduction

Advances in the management of bipolar disorder in children and adolescents: an update on the literature

INTRODUCTION

Early diagnosis and treatment concerning bipolar disorder (BD) are related to a better functioning over the long-term period. Although pharmacotherapy is indicated for approximately all youths with BD, nearly one-third of patients do not receive adequate medications for their condition.

AREAS COVERED

The authors discuss the available scientific evidence from the current literature about the management of BD in both children and adolescents, giving particular focus to the efficacy and tolerability of the available pharmacological agents. Studies were identified searching MEDLINE and retrieved from reference listings of relevant articles and through consultation with experts in the field.

EXPERT OPINION

Many D2-blockers, approved by the Food and Drug Administration (FDA) based on their antimanic properties in youths, are related to both short- and long-term side effects. Lurasidone was found to be effective for the treatment of acute juvenile bipolar depression, while lithium for the treatment and recurrence prevention of manic/mixed episodes. The most common anticonvulsants were found to be most useful as adjunctive antimanic agents in non-responders to first-line monotherapies. No data was found to support the use of antidepressants in juvenile BD.

Safety and efficacy of lithium in children and adolescents: A systematic review in bipolar illness

Introduction:

Many clinicians are reluctant to use traditional mood-stabilizing agents, especially lithium, in children and adolescents. This review examined the evidence for lithium’s safety and efficacy in this population.

Methods:

A systematic review was conducted on the use of lithium in children and adolescents with bipolar disorder (BD). Relevant papers published through June 30th 2018 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library.

Results:

30 articles met inclusion criteria, including 12 randomized controlled trials (RCTs). Findings from RCTs demonstrate efficacy for acute mania in up to 50% of patients, and evidence of long-term maintenance efficacy. Lithium was generally safe, at least in the short term, with most common side effects being gastrointestinal, polyuria, or headache. Only a minority of patients experienced hypothyroidism. No cases of acute kidney injury or chronic kidney disease were reported.

Conclusions:

Though the available literature is mostly short-term, there is evidence that lithium monotherapy is reasonably safe and effective in children and adolescents, specifically for acute mania and for prevention of mood episodes.

Historical Underpinnings of Bipolar Disorder Diagnostic Criteria

Mood is the changing expression of emotion and can be described as a spectrum. The outermost ends of this spectrum highlight two states, the lowest low, melancholia, and the highest high, mania. These mood extremes have been documented repeatedly in human history, being first systematically described by Hippocrates. Nineteenth century contemporaries Falret and Baillarger described two forms of an extreme mood disorder, with the validity and accuracy of both debated. Regardless, the concept of a cycling mood disease was accepted before the end of the 19th century. Kraepelin then described “manic depressive insanity” and presented his description of a full spectrum of mood dysfunction which could be exhibited through single episodes of mania or depression or a complement of many episodes of each. It was this concept which was incorporated into the first DSM and carried out until DSM-III, in which the description of episodic mood dysfunction was used to build a diagnosis of bipolar disorder. Criticism of this approach is explored through discussion of the bipolar spectrum concept and some recent examinations of the clinical validity of these DSM diagnoses are presented. The concept of bipolar disorder in children is also explored.

Actigraph measures discriminate pediatric bipolar disorder from attention-deficit/hyperactivity disorder and typically developing controls

BACKGROUND

Distinguishing pediatric bipolar disorder (BD) from attention-deficit hyperactivity disorder (ADHD) can be challenging. Hyperactivity is a core feature of both disorders, but severely disturbed sleep and circadian dysregulation are more characteristic of BD, at least in adults. We tested the hypothesis that objective measures of activity, sleep, and circadian rhythms would help differentiate pediatric subjects with BD from ADHD and typically developing controls.

METHODS

Unmedicated youths (N = 155, 97 males, age 5-18) were diagnosed using DSM-IV criteria with Kiddie-SADS PL/E. BD youths (n = 48) were compared to typically developing controls (n = 42) and children with ADHD (n = 44) or ADHD plus comorbid depressive disorders (n = 21). Three-to-five days of minute-to-minute belt-worn actigraph data (Ambulatory Monitoring Inc.), collected during the school week, were processed to yield 28 metrics per subject, and assessed for group differences with analysis of covariance. Cross-validated machine learning algorithms were used to determine the predictive accuracy of a four-parameter model, with measures reflecting sleep, hyperactivity, and circadian dysregulation, plus Indic's bipolar vulnerability index (VI).

RESULTS

There were prominent group differences in several activity measures, notably mean 5 lowest hours of activity, skewness of diurnal activity, relative circadian amplitude, and VI. A predictive support vector machine model discriminated bipolar from non-bipolar with mean accuracy of 83.1 ± 5.4%, ROC area of 0.781 ± 0.071, kappa of 0.587 ± 0.136, specificity of 91.7 ± 5.3%, and sensitivity of 64.4 ± 13.6%.

CONCLUSIONS

Objective measures of sleep, circadian rhythmicity, and hyperactivity were abnormal in BD. Wearable sensor technology may provide bio-behavioral markers that can help differentiate children with BD from ADHD and healthy controls.

Psychodynamics in child psychiatry in Sweden, 1945-85: from political vision to treatment ideology

In this article, changing treatment ideologies and policies in child psychiatric outpatient services in Sweden from 1945 to 1985 are examined. The aim is to discuss the role played by psychoanalytic and psychodynamic thinking in this process of change. When mental health services for children were introduced in the mid-1940s, psychoanalytic thinking was intertwined with the social democratic vision of the Swedish welfare state in which children symbolized the future. In practice, however, treatment ideology was initially less influenced by psychoanalytic thinking. From the early 1960s, child psychiatric services expanded and the number of units increased. By then, the political vision had disappeared, but a treatment ideology began to evolve based on psychodynamic theories, which became dominant in the 1970s.

The concept of bipolar disorder in children: a history of the bipolar controversy

Before the last 150 years, the use of the term mania to mean any kind of agitated state and the term childhood to include people up to their early 20s make historical identification of manic-depression in children difficult. Not long after Kraepelin's seminal work was published, similar syndromes were identified in youth, usually adolescents. Interestingly, however, the question of whether preadolescent mania should be broadly or narrowly defined--the so-called bipolar controversy--has been an issue for at least 50 years. Although the question of whether and how a disorder characterized by discrete episodes of mania and depression with periods of relative normality between episodes relates to one characterized by more fluctuating and intense mood lability/dysregulation remains unanswered, the work of researchers in the twenty-first century will be to understand not only symptoms of bipolar disorder but also how it develops and how emotion regulation relates to both the development of bipolar disorder and to other conditions that are characterized by dysregulated emotion.

Cycloid psychoses revisited: case reports, literature review, and commentary

Emil Kraepelin proposed to separate psychiatric disorders with psychotic features into two major categories, dementia praecox (later schizophrenia) and manic-depressive insanity (later bipolar disorder and major depression). Over the past century, there have been many efforts to categorize conditions that do not fit readily in either group. These conditions include many cases of acute psychotic illnesses of limited duration, with recovery between recurrences. For some of these conditions, Karl Kleist proposed the term cycloid psychosis: acute features were psychotic, as in schizophrenia, but the course was episodic, as in manic-depression. His concept was later elaborated by Karl Leonhard and Carlo Perris, and validated by modern studies. Leonhard described three overlapping cycloid subtypes (anxiety-beatific, excited-inhibited confusional, and hyperkinetic-akinetic motility dysfunction forms); Perris proposed a more unitary syndrome with operational diagnostic criteria; and recent investigators have considered relatively affective versus thought-disordered subtypes. The cycloid concept is not explicitly included in standard international diagnostic schemes, but both DSM-IV and ICD-10 have broad categories for acute, recurrent psychotic disorders, whose validity remains insecure. We present two cases of probable cycloid psychosis, review the history of the concept, and propose that it be reconsidered as a clinically useful category whose validity and utility for prognosis and treatment can be further tested.

Medicalizing melancholia: exploring profiles of psychiatric professionalization

The nineteenth century was the site of radical changes in understanding mental illness. The professionalization of psychiatry consisted primarily of the discipline's aspiration to the status of an expert medical subspecialty. While all forms of insanity were eventually reframed in medical terms, melancholia--for moral and nosological reasons--assumed a special role that made it an ideal diagnosis for conceptual reframing. Our analysis of the journal literature of the nineteenth and early twentieth centuries in North America and Germany traces several ways in which melancholia was medicalized. As the care for the insane shifted into the professional realm of physicians and medical terminology came to replace prior descriptors of mental illness, melancholia was replaced by depression. In addition, the process of delineating affective pathology assumed a distinctly medical flavor. Finally, melancholia was firmly medicalized when its boundaries blurred with neurasthenia. Differences in how ordinary affective terms became medicalized in German and North American psychiatry illustrate the importance of local historical approaches.

Psychiatrists' biographies

PURPOSE OF REVIEW

This review focuses on publications dealing with psychiatrists' biographies.

RECENT FINDINGS

Compared with scientific mainstream topics in psychiatry, the present area constitutes a small but nonetheless highly heterogeneous field. The selected papers are categorized with regard to what relevance is given to biographical data in a narrow sense or to conceptual issues for which the biography of a certain author functions as an illustration. Mere hagiographic biographical notes were not taken into consideration, and nor were plain polemics. Although the differentiation mentioned above seems useful in order to get an overview, it is de facto not possible to clearly separate biographical from conceptual aspects. This may be true for all fields in the history of science, but it is definitely true in the history of psychiatry with its numerous long-standing theoretical controversies - many of them still unresolved and all of them closely linked with the lives of their prominent representatives.

SUMMARY

The biographical approach can be helpful in proving that research on the history of psychiatry--if done beyond mere hagiography or simple polemic--is of crucial importance for the understanding and development of theoretical and practical issues in our field.
