A Naturalistic Study of Youth Referred to a Tertiary Care Facility for Acute Hypomanic or Manic Episode

Efficacy and Safety of Lithium for Suicide and Suicide-Related Behaviors in Youth: A Review of the Literature

OBJECTIVES

This systematic review evaluates the anti-suicidal properties of Lithium in children and adolescents with Bipolar Disorder (BD), addressing gaps in evidence regarding its efficacy and safety in reducing suicidality and self-harming behaviors.

METHODS

A comprehensive literature search was conducted across PubMed, Web of Science, and Scopus up to February 2024. Eligible studies were those focusing on patients aged 25 years or younger, examining Lithium therapy and its impact on suicidal ideation and behaviors. The review included randomized controlled trials, longitudinal prospective and retrospective studies, and cross-sectional studies, while excluding expert opinions and case reports.

RESULTS

Evidence generally supports the efficacy of Lithium in reducing suicidal ideation and self-harming behaviors in youth with BD, though results are mixed. Randomized controlled trials demonstrated its effectiveness in mitigating suicidal thoughts during acute manic episodes, with effects persisting post-treatment. Longitudinal studies suggested that Lithium might offer superior outcomes compared to other mood stabilizers, although its specific impact on suicidality remains inconclusive. Cross-sectional studies and retrospective analyses reveal associations between Lithium use and reduced self-harming behaviors, but causality remains uncertain. While mood-stabilizing effects of Lithium offer potential benefits for reducing suicidality in youth, evidence on its direct impact on emotional dysregulation (ED) and long-term efficacy is limited. Variability in individual responses and adherence issues underscore the need for further research. Future studies should include larger, diverse samples, focus on ED symptoms, and explore Lithium mechanisms in suicidality prevention.

CONCLUSIONS

Lithium remains a promising treatment for mood stabilization and reduction in suicidality in youth with BD.

Clinical assessment of impulsiveness and defence mechanisms in young patients with mood disorders in a two-year prospective study

AIM

There have been limited prospective investigations of early clinical markers involved in mood regulation and diagnosis change in young patients. This study aimed to evaluate the changes in impulsivity and defence mechanisms in patients with major depressive disorder (MDD) and bipolar disorder (BD) with acute symptoms and remission compared to healthy controls (HC), and possible psychological predictors of diagnosis conversion.

METHODS

Seventy-nine young MDD or BD patients and 40 HC were enrolled in a two-year prospective study. A comprehensive clinical interview focused on clinical and psychological evaluation during follow-up visits. The severity of depressive symptoms was evaluated using the Hamilton Depression Rating Scale (HDRS-17), whilst the Young Mania Rating Scale (YMRS) was used for hypo/manic symptoms during each control visit. All patients completed the Defence Style Questionnaire (DSQ-40) and Barratt Impulsiveness Scale (BIS-11).

RESULTS

Patients used more immature defences, and had significantly higher total impulsivity scores than controls. BD patients had elevated motor and non-planning impulsivity compared with HC and MDD subjects. Total and non-planning impulsiveness remained elevated in euthymia in BD and MDD compared to HC. There were no statistically significant differences in total defence styles and impulsiveness scores at baseline vs. euthymia in MDD or BD patients groups. Significantly higher dissociation scores at baseline discriminated depressive patients who convert to BD in their diagnosis.

CONCLUSIONS

Patients with acute mood symptoms used more frequent immature defences and had significantly higher total impulsivity scores than healthy persons. A lack of differences in total defence styles and impulsiveness between patients with acute symptoms and after reaching euthymia in both MDD and BD groups indicates that they are independent of disease status. Dissociation defence mechanisms may be an early diagnostic indicator of BD.

Suicidal behavior in juvenile bipolar disorder and major depressive disorder patients: Systematic review and meta-analysis

OBJECTIVE

To assess rates and lethality of suicidal behavior in studies of children and adolescents diagnosed with major depressive disorder (MDD) or bipolar disorder (BD).

METHODS

This PROSPERO-registered protocol (CRD-42019159676) systematically reviewed reports on suicidal behavior among juveniles (age ≤ 18 years), and pooled data on risk (% of subjects) and rates (%/year), followed by random-effects meta-analysis and multivariable linear regression modeling.

RESULTS

Included were 41 reports (1995-2020) from 15 countries involving 104,801 juveniles (102,519 diagnosed with MDD, 2282 with BD), at risk for 0.80-12.5 years. Meta-analytically pooled suicide attempter-rates averaged 7.44%/year [95%CI: 5.63-9.25] with BD and 6.27%/year [5.13-7.41] with MDD. Meta-analysis of 5 studies with both diagnostic groups found significantly greater attempt risk with BD vs. MDD (OR = 1.59 [1.24-2.05], p < 0.0001). In 6 studies, suicide rate with juvenile mood disorders averaged 125 [56.9-236]/100,000/year, similar to adult rates, >30-times greater than in the general juvenile population, and higher among older adolescents. The ratio of attempts/suicides (A/S) was 52.6 among mood-disordered juveniles, indicating greater lethality than among juveniles in the general population (A/S ≥ 250), but somewhat less than in the estimated adult general population (A/S ca. 30).

CONCLUSIONS

Rates of suicide attempts in juveniles with a major mood disorder averaged 6580/100,000/year, were greater in BD versus MDD observed under the same conditions, and greater with shorter periods of observation. Lethality (fatalities per suicide attempt) was greater in juveniles diagnosed with major affective disorders than in the juvenile general population, but less than in adults.

Co-occurring Mental Disorders in Transitional Aged Youth With Substance Use Disorders - A Narrative Review

Adolescence and emerging adulthood are often referred to as youth. Transitional psychiatry addresses this target group, which considers patients between 15 and 25 years of age. Substance use usually begins and peaks at this stage of life. Psychiatric disorders, foremost attention-deficit/hyperactivity disorder, and affective disorders, conduct disorders, and first-episodes psychosis frequently appear in early life stages. This review aims to provide a broad overview of transitional-aged youth's most common psychiatric comorbidities with substance use disorders. A literature search was conducted in Embase and Pubmed, and the main findings are described narratively. We present main findings for the following comorbidities: attention-deficit/hyperactivity disorder, conduct disorder, personality disorders, affective disorders, psychotic disorders, and the phenomena of overdose and suicidality. In conclusion, co-occurring mental health disorders are common and appear to facilitate the development of substance use disorders and exacerbate their overall course. Substance use also affects the severity and course of comorbid psychiatric disorders. Overall, data on transition-age youth with substance use disorders are highly inconsistent. Universal screening and treatment guidelines do not yet exist but should be aimed for in the future.
