• Pediatric Bipolar Disorders in Children and Adolescents
Mania – discrete period of elevated, expansive, or irritable mood and increased level of energy and activity
DSM-5
Pediatric Bipolar I Disorder
Pediatric Bipolar II Disorder
Cyclothymic Disorder
Pediatric Bipolar I Disorder
• Pediatric Bipolar I Disorder in Children and Adolescents
Experience at least one manic episode preceded or followed by a major depressive or hypomanic episode(s)
Last at least 1 week and symptoms are present most of the day; nearly every day
1 week waived if hospitalization is required
3 or more of the following (4 or more if irritable mood):
Decreased need for sleep
More talkative
Fight of ideas or feel thoughts are racing
Increased in goal-behavior
Excessive involvement in activities with possible harmful consequences
Marked impairment in social or occupational functioning or need for hospitalization, or there are psychotic features
• Pediatric Bipolar I Disorder in Children and Adolescents
Manic Episodes and Children
Report expansive mood, elevation, and increased energy
Elevated mood and increased energy: cardinal symptoms
90% experienced increased energy
Many report irritable mood during manic episodes
Mood: touchy, angry, oppositional, or reactive
81% show irritable mood
• Pediatric Bipolar I Disorder in Children and Adolescents
Manic Episodes and Children
Three manic symptoms regularity observed:
About 80%

Increased in goal-behavior
Excessive involvement in activities with possible harmful consequences
Unequivocal change in functioning and observed by others
Not severe enough to impair social or occupational functioning or necessitate hospitalization.
• Pediatric Bipolar II Disorder in Children and Adolescents
Hypomania is somewhat difficult to assess in children
Does not lead to marked distress or impairment in functioning
Major depressive episode
Pediatric Bipolar II = major depressive episode + hypomanic episode
Pediatric Bipolar I = major depressive episode + manic episode
Cyclothymic Disorder
• Cyclothymic Disorder in Children and Adolescents
Rarely diagnosed in children and adolescents
Defined by periods of hypomanic symptoms that do not meet full criteria and periods of depressive symptoms that do not meet full criteria
Experience symptoms for at least 1 year, and must not be symptom free for more than 2 months
Clinically significant distress or impairment
Pediatric Bipolar Disorders: Problems and Differentiation
• Problems associated with PBD
Psychotic Features
Hallucinations or Delusions
DSM-5 Specification: presence of psychotic symptoms
Tend to have worse outcomes
Tend to show mixed signs and symptoms during a single mood episode
Mixed mood: meet criteria for either a manic or hypomanic episode and simultaneously show subthreshold symptoms of depression or vise versa
• Differentiation PBD from Other Conditions
Externalizing Behavior Problems
Comorbid with:
ODD
Substance Use
May have some overlap in some symptoms, but are manifesting the symptoms for different reasons
Disruptive Mood Dysregulation Disorder
Children with DMDD and Pediatric Bipolar disorders can show irritability and angry outbursts
Pediatric Bipolar Disorders: Prevalence, Course, and Outcomes
• Prevalence, Course, and Outcomes
Prevalence
Lifetime sample rate: 1.9%
Clinic sample rate: 6%-7%
Psychiatric hospital rate: 26%-34%
Gender
Bipolar I disorder: no gender, but symptom differences
Comorbid Differences:
Girls: greater risk for anxiety disorders
Boys: greater risk for ADHD
Ethnicity
No ethnicity differences, but symptom presentation may vary across ethnicities
• Prevalence, Course, and Outcomes
Youth usually begin showing prodromal, subthreshold mood problems, months or years before their first mood episode.
Common mood problems: dysphoria, concentration difficulties, irritability, agitation
Once a full-blown mood episode is experienced, symptoms usually persist for some time
One study: 2.5 years after the first mood episode 81.5% of youth fully recovered
Relapse is not uncommon
• Prevalence, Course, and Outcomes
Outcomes
Greater risk for:
Frequency of manic symptoms
Less remission of symptoms and relapse over time
Greater number of psychiatric hospitalizations
Education, employment, and substance use problems
No medication used as intervention
Greater risk for:
Recurrent episodes of mania and depression
Employment and relationship problems
Legal problems
Hospitalizations
Substance use disorders
Suicide
• Higher Socioeconomic Status and Less Parental Psychopathology Improve Prognosis in Youths with Bipolar Disorder (Diler et al., 2022)
Method
Participants:
Diagnosis of BD-I, BD-II or BD-NOS
Improving Group
70 youth, Mage = 12.3 (BD-I/II = 40 and BD-NOS = 30)
Ill Group
82 youth, Mage = 11.7 (BD-I/II = 54 and BD-NOS = 28)
Longitudinal and correlational
Method of Observation:
Youth and caregivers completed interviews and questionnaires at baseline follow-up (Myears = 12.8) to assess:
Mood trajectories
Functional assessment
Demographic and other clinical assessments (e.g., anxiety, parental psychopathology)
Results
Since intake the Improving Group, compared to the Ill Group, showed:
Lower subthreshold depression and hypo/mania
ADHD
Disruptive behavior disorders
Parental SES
Since intake parental SES remined unchanged for the Ill Group, but increased for the Improving Group
Prediction of Improvement
Higher SES + absence of parental BD and substance use disorder = better outcomes
Parental substance use disorder predicted lower SES = poor outcomes
Message
Pediatric Bipolar Disorders: Risk Factors
• Pediatric Bipolar Disorders: Risk Factors
Genes
Greatest risk: having a biologically related family member with a bipolar disorder
MZ higher concordance rate than DZ
PBD: Risk Factors
• Pediatric Bipolar Disorders: Risk Factors
Brain Structure and Functioning
Smaller brains
Impairment areas associated with emotion processing and emotion regulation
Hyperactivation of the amygdala
Hypoactivation in areas of the prefrontal cortex
Implications:
Misinterpret the emotional expressions of others in a hostile or threatening way, followed by personally more negative emotions
Poor regulation of negative emotions may be associated with acting out
• Pediatric Bipolar Disorders: Risk Factors
Emotion Regulation
As shared:
May have problems directing their attention aways from negative events and experience
Once upset, they may also have difficulty regulating their emotions to deal effectively with problems
Stressful Life Events
Youth with bipolar report:
• Pediatric Bipolar Disorders: Risk Factors
Family Functioning
Three Patterns:
Negative thoughts, feelings, and actions can be elicited from parents
Parents may have mood disorders
Expressed Emotion (EE)
Degree to which caregivers display criticism, hostility or emotional overinvolvement toward a family member with a mental health problem
Pediatric Bipolar Disorders: Assessment
• Pediatric Bipolar Disorders: Assessment
Assessment Tools
Self-report interviews and questionnaires
Observations
Medical exams
Brain imaging
Pediatric Bipolar Disorders: Intervention
• Pediatric Bipolar Disorders: Risk Factors
Medication
Medication is the primary form of treatment
Lithium is not considered as a first-line treatment for youth due to lack of efficacy and side effects
Used to treat seizures have been used to treat mania in adults
Decreases neural activity
May be effective in youth, but may have side effects
Most frequently prescribed medications
Shown effective in the reduction of manic or mixed symptoms
Not all youth respond, recovery rates are low, and may have side effects
• Pediatric Bipolar Disorders: Risk Factors
Psychotherapy
Purpose of Psychotherapy
Teach coping and family communication skills to prevent relapse
Common Components
Psychoeducation
Family involvement
Reducing blame
Skill building
• Pediatric Bipolar Disorders: Risk Factors
Psychotherapy
Child- and Family-Focused Cognitive-Behavioral Therapy
Children aged 7 to 13 and their caregivers
Monitoring and regulating emotions
Improving parent-child interactions
Managing disruptive child behavior
Psychoeducational Psychotherapy
Children ages 8 to 12 and their caregivers, but younger and older youth also participate
Teaches families about mood disorders, emotion regulation, and problem-solving skills
Older children and adolescent their family members
Works to improve parent-child communication and problem-solving – decrease expressed emotions
• Schizophrenia
Bizarre delusions (false beliefs)
Hallucinations (false perceptions)
Thought disturbances
Grossly disordered behavior or catatonic behavior
Extremely inappropriate or flat affect
Significant deterioration or impairment in functioning
• Childhood and Adolescent Onset Schizophrenia
A progressive neurodevelopmental disorder that causes significant distress and disability
Worse long-term outcomes
COS is rare
• DSM-5: Schizophrenia
Symptoms –two (or more) – 1-month presence
Delusions, hallucinations, grossly disorganized speech and behavior, flat affect/motivation
Persistence
1 month+ of psychotic symptoms
Functioning
Significant impairment in one or more areas of functioning
For children and adolescents – a failure to achieve expected levels of interpersonal, academic, or occupational achievement
•
Involve excesses in typical functioning
Children with COS may display psychotic symptoms
Most common presenting symptom is auditory hallucinations
Children can also experience visual hallucinations, delusions, and thought disturbances
Developmental Considerations
Early psychotic symptoms may be less complex or reflect childhood themes
Children might not experience psychotic symptoms as distressing or disorganizing
•
Absent or impoverished behavior with respect to typical functioning
Blunted or flat affect
Avolition
Social withdraw
Passivity or Apathy
Lack of spontaneity
Reflect a loss of motivation and can range from minor to severe
Can be persistent and difficult to treat
Developmental Consideration
Can be difficult to recognize in younger individuals
• Differentiate: Positive and Negative Symptoms
The symptoms have different underlying neurobiological causes
Negative: underactivity in frontal brain regions
Prevalence and severity of symptoms changes over time
Predominately positive symptoms tend to precede the emergence of predominately negative symptoms
Symptoms respond differently to intervention
Antipsychotic medication: less effective for negative symptoms
• DSM-5: Schizophrenia
Differential Diagnosis
Do not diagnosis schizophrenia if psychotic symptoms are attributed to:
Medical illness
Drug use
Autism Spectrum Disorder
Schizophrenia can be diagnosed comorbid with ASD only when hallucinations and delusions are present
• DSM-5: Schizophrenia
Comorbidity and Schizophrenia
Cognitive Impairments
Movement abnormalities
Mental Health Disorders
Anxiety Disorders
Major Depression

• Schizophrenia: Course
Schizophrenia typically progresses through a series of stages over months or years
The Premorbid Stage: Problems in Early Life
The Prodromal Stage: Noticeable Changes
The Acute State: Positive Symptoms and Impairment
The Residual Stage: Chronic Problems
• The Premorbid Stage: Problems in Early Life
Show no overt symptoms, but many who later develop schizophrenia demonstrate behavioral, social, and emotional problems
Developmental Observations
Learning problems
Cognitive functioning delays
Movement abnormalities (e.g., facial tics, grimaces)
Social impairment (e.g., social withdrawal, social oddities)
Unusual thought content
• The Prodromal Stage: Noticeable Changes
Prodromal symptoms may emerge 2 to 6 years before the first psychotic episode
Marked impairment in academic, behavioral, and social-emotional functioning
May demonstrate:
Restless and irritability
Negligence of appearance and hygiene
• The Acute Stage: Positive Symptoms and Impairment
Onset of positive symptoms
Acute phase lasts about 1 to 6 months, depending on intervention
• The Residual Stage: Chronic Problems
Can last for several months to years
Variation in functioning:
Some: improvement
Most: experience negative symptoms and continued impairment
• Outcome
Short-Term Prognosis
Poor
Psychotic symptoms typically persist for several months
20% of patients: “good” outcomes
Alleviation of positive symptoms, mild negative symptoms and a general return to functioning
Long-Term Prognosis
Childhood and adolescent onset tend of have poorer outcomes
Schizophrenia: Risk Factors
• Schizophrenia: Risk Factors
Genetics
Supported by family, twin, and adoption studies
Transmission:
Candidate genes
Genetic abnormalities or mutations
• Schizophrenia: Risk Factors
Brain Development
Adulthood Onset
Larger ventricles
Reduced total volume and thickness of the prefrontal, temporal, and parietal cortices
Reduced size of the hippocampus and thalamus
Research on Childhood and Adolescence Onset
Abnormalities tended to occur earlier in disorder course
Show dramatic reductions in gray matter that predict the onset of psychosis
• Schizophrenia: Risk Factors
Neural Pathways
Dopamine-rich pathway
Dopamine Hypothesis
Excessive stimulation D2 receptors along the pathway contribute to the positive symptoms
Dopamine-rich pathway
Hypofrontality Hypothesis
Underactivity of D1 receptors along the pathway contribute to negative symptoms
• Schizophrenia: Risk Factors
Environmental Risks
Prenatal maternal stress and exposure to disease
Pre- or peri-natal complications
Major life events
Especially those perceived as “uncontrollable”
Positive and negative
Stressors associated with immigration and acculturation
Cannabis use in adolescence
• Schizophrenia: Risk Factors
Neurodevelopmental Model
Development of Schizophrenia
Early environment stressors, combined with biogenetic risk factors (from birth) lead to abnormalities in the organization and development of CNS
Abnormalities of the CNS initially manifest as premorbid differences
Abnormalities in the organization and development of the brain then manifest as prodromal signs and symptoms
Schizophrenia: Assessment
• Schizophrenia: Assessment
Assessment Tools
Self-report interviews and questionnaires
Parent report interviews and questionnaires
Observations
Medical exams
Schizophrenia: Intervention
• Schizophrenia: Intervention
Medication
Conventional Antipsychotics
Act as a dopamine antagonist by binding to D2 receptors, particularly in the mesolimbic pathway.
Effective in reducing positive symptoms.
Problems:
Less effective in reducing negative symptoms.
Can produce problematic side effects.
Atypical psychotics
Act as a dopamine antagonist (but weaker bind) and bind to serotonin.
Effective in reducing positive and negative symptoms.
Problems:
Can produce problematic side effects.
• Schizophrenia: Intervention
Psychotherapy
Recommendation: mediation and psychotherapy.
Components of most psychotherapies:
Psychoeducation
Medication adherence
Cognitive-behavioral interventions
Family-based interventions
Integration back into the community
Efficacy
Limited research, but disappointing results for psychotherapy
Promising: family therapy
Bipolar disorder 2: a DSM-5 disorder characterized by at least one hypomanic episode and one major depressive episode that results in a marked change in functioning but does not lead to impairment or require hospitalization.
Child-and family-focused cognitive-behavioral therapy ICFF-cB: Treatment for children (aged 7-13) with bipolar disorders and their caregivers; components include.(1) monitoring and regulating emotions, (2) improving parent-child interactions, and (3)managing disruptive child behavior.
Course and Outcome of Bipolar Youth (COBY) study: A large study of the course of bipolar disorders in children: results showed that most youths with bipolar disorders recovered from their symptoms, continued to experience mood problems, and experienced another mood episode.
Cyclothymic disorder: A DSM-5 disorder characterized by periods of hypomanic symptoms (but not a hypomanic episode) and depressive symptoms (but not a major depressive episode) lasting at least 1 year in children and adolescents.
Delusions: Erroneous, often bizarre, beliefs that usually involve a misinterpretation of perceptions or experiences.
Dopamine hypothesis: Posits that the positive symptoms of schizophrenia are caused by excessive stimulation of certain dopamine receptors (D2 receptors) along the mesolimbic pathway.
Expressed emotion (EE): Criticism, hostility, or emotional overinvolvement toward a family member with a psychiatric disorder.
Extrapyramidal Side effects: Side effects associated with the use of conventional antipsychotics; include problems Initiating movements, feelings of restlessness, and tardive dyskinesia.
Family-focused treatment for adolescents (FFT-A): A family systems therapy for adolescents with bipolar disorder and their caregivers; seeks to improve parent-child communication and problem-solving and avoid future mood episodes by decreasing expressed emotion.
Flight of ideas: Racing thoughts often experienced by people with mania or hypomania.
Goal-directed activity: A tendency to initiate a wide range of new behaviors
Grandiosity: Unusually high self-confidence, exaggerated self-esteem, and overrated self-importance.
Hallucinations: Erroneous, often bizarre, perceptions that do not correspond to reality.
Hypofrontality hypothesis: Posits that underactivity among certain dopamine receptors (D1 receptors) in the mesocortical pathway is responsible for the negative symptoms of schizophrenia.
Hypomanic episode: A distinct period of abnormally, persistently elevated, expansive, or irritable mood and increased activity and energy, lasting at least 4 days, but less than 1 week, and occurring most of the day nearly every day.
Insula: A centrally located region of the brain responsible for emotion regulation, self-awareness, and interpersonal functioning.
Lateral ventricles: Canals in the center of the brain that are filled with cerebrospinal fluid; sometimes enlarged in adults with schizophrenia.
Lithium (Eskatith): A mood-stabilizing medication used to treat bipolar disorders in adults; regulates norepinephrine and serotonin.
Mania: A discrete period of abnormally, persistently elevated, expansive, or irritable mood and increased level of energy and activity; an essential feature of all DSM-5 bipolar disorders.
Manic episode: A distinct period of abnormally, persistently elevated, expansive, or irritable mood and increased activity and energy, lasting at least 1 week and occurring most of the day nearly every day.
Mixed mood: The presence of either a manic or hypomanic episode and subthreshold symptoms of depression or, alternatively, the presence of a major depressive episode and subthreshold hypomanic symptoms.
Negative symptoms: Features of schizophrenia that reflect behavioral "underexpressions"; include flat affect, avolition, social withdrawal, passivity, apathy, and lack of spontaneity.
Negatively escalating cycle of communication: Parent-child interaction in which criticism from one family member elicits countercriticism from another family member, until it is difficult to resolve; usually involves a three-volley sequence.
Neurodevelopmental model for schizophrenia: Posits that early environmental stressors, combined with biogenetic risk factors, lead to abnormalities in the organization and development of the central nervous system; these abnormalities can be triggered to produce schizophrenia.
Neuroleptic malignant syndrome (NMS): A rare condition caused by an initial, high dose of conventional antipsychotic medication; characterized by severe muscle rigidity, loss of motor control, fever, and high blood pressure.
