Insights

Children with delirium referred to psychiatry face high mortality risks and complex causes. While antipsychotics like haloperidol and risperidone show moderate effectiveness, more research is needed for treatment guidelines.

Area of Science:

  • Pediatric Psychiatry
  • Child and Adolescent Psychiatry
  • Neuroscience

Background:

  • Delirium is an underresearched condition in pediatric populations.
  • Hospitalized children and adolescents with delirium present unique clinical challenges.

Purpose of the Study:

  • To characterize the demographic and clinical profile of pediatric delirium cases referred to psychiatry.
  • To assess mortality rates and treatment effectiveness in this patient group.

Main Methods:

  • Prospective case series of 23 children and adolescents diagnosed with delirium.
  • Referral to a consultation-liaison psychiatry service in a South African children's hospital.
  • Diagnosis based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria.

Main Results:

  • Patients represent a high-risk subgroup with significant mortality.
  • Complex, multifactorial, and often uncertain etiologies were observed.
  • Haloperidol and risperidone demonstrated moderate effectiveness in uncontrolled data when used with specific criteria.

Conclusions:

  • Delirium in children and adolescents is a critical, understudied area.
  • Tentative criteria for antipsychotic use are proposed.
  • Urgent need for controlled studies comparing pharmacological and non-pharmacological treatments.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Dementia l: Introduction01:22

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
