About This Presentation

Description : Check out this medical PowerPoint presentation titled "Attention-Deficit/Hyperactivity Disorder (ADHD)" by Eric J. Mash and David A. Wolfe.
This medical PowerPoint presentation talks about Attention-Deficit/Hyperactivity Disorder (ADHD).
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects people of all ages, although it is commonly diagnosed in children. ADHD is characterized by inattention, hyperactivity, and impulsivity that interfere with daily functioning and development.
Predominantly Inattentive Presentation, Predominantly Hyperactive-Impulsive Presentation and Combined Presentation are the three subtypes of ADHD.
The exact cause of ADHD is not fully understood, but it is believed to be a combination of genetic and environmental factors. Diagnosis is typically made through a comprehensive evaluation, including a medical exam, interviews, and rating scales.
Treatment for ADHD often involves a combination of medication, behavioral therapy, and lifestyle changes. Medications such as stimulants are commonly used to manage symptoms, while behavioral therapy can help individuals with ADHD develop coping strategies and improve social and academic functioning.

Slide 1-

Attention-Deficit/HyperactivityDisorder (ADHD) 8
Slide 2-

Attention-deficit/hyperactivity disorder (ADHD) is exhibited as persistent age-inappropriate symptoms of inattention, hyperactivity, and impulsivity that are sufficient to cause impairment in major life activities Characteristic behaviors vary considerably from child to child Different behavior patterns may have different causes Description
Slide 3-

Early 1900s Children who lacked self-control and showed symptoms of overactivity/inattention in school were said to have poor “inhibitory volition” and “defective moral control” Following the worldwide influenza epidemic from 1917-1926 “Brain-injured child syndrome” 1940s-1950s: “minimal brain damage” and “minimal brain dysfunction” History
Slide 4-

Historical Example
Slide 5-

Late 1950s ADHD was called hyperkinesis Led to definition of hyperactive child syndrome, in By the 1970s Deficits in attention and impulse control, in addition to hyperactivity, were seen as the primary symptoms 1980s saw increased interest in ADHD Rise in stimulant use generated controversy History (cont’d.)
Slide 6-

Key symptoms fall under two well-documented categories Inattention Hyperactivity-impulsivity Using these dimensions to define ADHD oversimplifies the disorder Attention and impulse control are closely connected developmentally Core Characteristics
Slide 7-

DSM-V Diagnostic Criteria for ADHD
Slide 8-

DSM-V Diagnostic Criteria for ADHD (cont’d.)
Slide 9-

DSM-V Diagnostic Criteria for ADHD (cont’d.)
Slide 10-

Inability to sustain attention, particularly for repetitive, structured, and less enjoyable tasks Deficits may be seen in one or more types of attention Attentional capacity Selective attention Distractibility Sustained attention/vigilance (a core feature) Inattention
Slide 11-

Inability to voluntarily inhibit dominant or ongoing behavior Hyperactive behaviors include Fidgeting and difficulty staying seated Moving, running, touching everything in sight, excessive talking, and pencil tapping Excessively energetic, intense, inappropriate, and not goal-directed Hyperactivity-Impulsivity
Slide 12-

Impulsivity Inability to control immediate reactions or to think before acting Cognitive impulsivity includes disorganization, hurried thinking, and need for supervision Behavioral impulsivity includes difficulty inhibiting responses when situations require it Emotional impulsivity includes impatience, low frustration tolerance, hot temper, quickness to anger, and irritability Hyperactivity-Impulsivity (cont’d.)
Slide 13-

Predominantly inattentive presentation (ADHD-PI) Predominantly hyperactive–impulsive presentation (ADHD-HI) Combined presentation (ADHD-C) ADHD Presentation Types
Slide 14-

Inattentive, drowsy, daydreamy, spacey, in a fog, and easily confused May have learning disability, process information slowly, have trouble remembering things, and display low academic achievement Often anxious, apprehensive, socially withdrawn, and may display mood disorders Predominantly Inattentive Type (ADHD-PI)
Slide 15-

Primarily symptoms of hyperactivity-impulsivity (rarest group) Primarily includes preschoolers and may have limited validity for older children May be a distinct subtype of ADHD-C Predominantly Hyperactive-Impulsive Type (ADHD-HI)
Slide 16-

Children who have symptoms of both inattention and hyperactivity-impulsivity Most often referred for treatment Combined Type (ADHD-C)
Slide 17-

Appears prior to age 12 Persists more than 6 months Occurs more often and with greater severity than in: Other children of the same age and sex Occur across two or more settings Interferes with social or academic performance Not explained by another disorder Additional DSM Criteria
Slide 18-

Limitations of DSM criteria for ADHD Developmentally insensitive Categorical view of ADHD DSM criteria shape our understanding of ADHD DSM criteria are also shaped by, and in some instances lag behind, new research findings What DSM Criteria Don’t Tell Us
Slide 19-

Children with ADHD often display other problems in addition to their primary difficulties Cognitive deficits Speech and language impairments Developmental coordination and tic disorders Medical and physical concerns Social problems Associated Characteristics
Slide 20-

Cognitive processes Language processes Motor processes Emotional processes Cognitive Deficits: Executive Functions
Slide 21-

Examples of Impaired Executive Functions
Slide 22-

Intellectual deficits Most children with ADHD have at least normal intelligence - the difficulty lies in applying intelligence to everyday life situations Impaired academic functioning Children with ADHD frequently have lower productivity, grades, and scores on achievement tests Cognitive Deficits: Intellectual and Academic
Slide 23-

Learning disorders are common for children with ADHD Problem areas: reading, spelling, and math Distorted self-perceptions Positive bias: exaggeration of one’s competence Self-esteem in children with ADHD may vary with the subtype of ADHD Distortions in perceptions of quality of life Cognitive Deficits: Learning Disorders and Self-Perceptions
Slide 24-

Formal speech and language disorders Difficulty understanding others’ speech Excessive and loud talking Frequent shifts and interruptions in conversation Inability to listen Inappropriate conversations Speech production errors Speech and Language Impairments
Slide 25-

As many as 30-50% of children with ADHD display motor coordination difficulties Clumsiness, poor performance in sports, or poor handwriting Overlap exists between ADHD and developmental coordination disorder (DCD) Marked motor incoordination and delays in achieving motor milestones Developmental Coordination and Tic Disorders
Slide 26-

Tic disorders occur in 20% of children with ADHD Sudden, repetitive, nonrhythmic motor movements or sounds such as eye blinking, facial grimacing, throat clearing, and grunting Developmental Coordination and Tic Disorders (cont’d.)
Slide 27-

Health-related problems Higher rates of asthma and bedwetting Studies’ findings are inconsistent Sleep disturbances may be related to use of stimulant medications and/or co-occurring conduct or anxiety disorders Medical and Physical Concerns
Slide 28-

Accident-proneness and risk taking Over 50% are described as being accident-prone At higher risk for traffic accidents At risk for early initiation of cigarette smoking, substance use disorders, and risky sexual behaviors Reduced life expectancy Higher medical costs Medical and Physical Concerns (cont’d.)
Slide 29-

Family problems include: Negativity, child noncompliance, excessive parental control, sibling conflict, maternal depression, paternal antisocial behavior, and marital conflict Family difficulties may be due to co-occurring conduct problems Social Problems
Slide 30-

Peer problems ADHD children can be bothersome, stubborn, socially awkward, and socially insensitive They are often disliked and uniformly rejected by peers, have few friends They are unable to apply their social understanding in social situations Positive friendships may buffer negative outcomes Social Problems (cont’d.)
Slide 31-

Up to 80% of children with ADHD have a co-occurring psychological disorder Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD) Role of COMT gene A common genetic contribution for ADHD, ODD, and CD Family connections – there is evidence for a contribution from a shared environment Accompanying Psychological Disorders and Symptoms
Slide 32-

Anxiety disorders About 25% of children with ADHD experience excessive anxiety Co-occurring anxiety worsens symptoms or severity of ADHD Findings are inconsistent Children with co-occurring ADHD and anxiety: Display social and academic difficulties Experience greater long-term impairment and mental health problems Accompanying Psychological Disorders and Symptoms Anxiety Disorders
Slide 33-

Mood disorders ADHD at 4-6 years is a risk factor for future depression and suicidal behavior 20-30% of children with ADHD experience depression Family risk for one disorder may increase the risk for the other Controversy regarding relationship between ADHD and pediatric bipolar disorder (BP) Accompanying Psychological Disorders and Symptoms Mood Disorders
Slide 34-

Prevalence rates vary widely with sampling methods Estimates: 6-7% of school-age children and adolescents in North America and 5% worldwide have ADHD ADHD is one of the most common referral problems seen at clinics Prevalence and Course
Slide 35-

ADHD occurs more frequently in boys Overall rates decrease in adolescence for both sexes - ratio remains the same Ratio in clinical samples is 6:1 with boys being referred more often than girls ADHD in girls may go unrecognized and unreported DSM criteria (cutoffs and symptoms) may be more appropriate to boys than girls Gender
Slide 36-

Girls with ADHD may be more likely to display inattentive/disorganized symptoms Clinic-referred school-age children with ADHD display similar symptoms Girls with ADHD who display impulsive-hyperactive behaviors More likely to develop eating disorder symptoms Gender (cont’d.)
Slide 37-

ADHD affects children from all social classes Slightly more prevalent among lower SES groups Findings are inconsistent regarding relationships among ADHD, race, and ethnicity ADHS is found in all countries and cultures Rates vary Socioeconomic Status and Culture
Slide 38-

Cultural differences may reflect cultural norms and tolerance for ADHD symptoms ADHD is a universal phenomenon that is diagnosed more often in boys than girls in all cultures Expression, associated features, impairments, and outcomes are quite similar wherever it occurs Socioeconomic Status and Culture (cont’d.)
Slide 39-

Infancy Signs of ADHD may be present at birth - no reliable or valid methods exist to identify it Preschool Hyperactivity-impulsivity symptoms become more visible and significant at ages 3-4 Children with symptoms for at least 1 year are likely to continue to have difficulties later in middle childhood and adolescence Course and Outcome
Slide 40-

Symptoms are especially evident when the child starts school Oppositional defiant behaviors may increase or develop By age 8-12, defiance and hostility may take the form of serious problems Increased problems may encompass self-care, personal responsibility, chores, trustworthiness, independence, social relationships, and academic performance Course and Outcome Elementary School
Slide 41-

Many children with ADHD do not outgrow problems and some can get much worse At least 50% of clinic-referred elementary school children continue to suffer from ADHD into adolescence Adult challenges Some individuals either outgrow or learn to cope with their disorder by adulthood ADHD is established as an adult disorder Course and Outcome Adolescence and Adulthood
Slide 42-

Explanations for ADHD Trait from evolutionary past as hunters ADHD is a myth fabricated because society needs it Some theories Cognitive functioning deficits Reward/motivation deficits Arousal level deficits Self-regulation deficits Theories and Causes
Slide 43-

A Possible Developmental Pathway for ADHD
Slide 44-

ADHD runs in families Adoption studies Twin studies 75% heritability estimates for hyperactive-impulsive and inattentive behaviors Specific gene studies Genes may contribute to the expression of ADHD – focus on dopamine regulation Genetic Influences
Slide 45-

Factors that compromise development of the nervous system before and after birth may be related to ADHD Mother’s use of cigarettes, alcohol, or other drugs during pregnancy are associated with ADHD Contributing factors, rather than a causal association It is difficult to disentangle substance abuse influence and other environmental factors Pregnancy, Birth, and Early Development
Slide 46-

Research shows differences on: Psychophysiological measures Diminished arousal or arousability Measures of brain activity during vigilance tests Under-responsiveness to stimuli/deficits in response inhibition Blood flow to prefrontal regions and pathways connecting them to limbic system Decreased blood flow to these regions Neurobiological Factors
Slide 47-

Abnormalities primarily in the frontostriatal circuitry are implicated This region includes the prefrontal cortex and the basal ganglia ADHD children have smaller total and right cerebral volumes (by 3-4%), smaller cerebellum, and delayed brain maturation Specific regions of the thalamus may also be involved Brain Abnormalities
Slide 48-

No consistent differences have been found between children with and without ADHD Some neurotransmitters may be involved Dopamine, norepinephrine, epinephrine, and serotonin may be involved Most evidence suggests a selective deficiency in availability of dopamine and norepinephrine Using medication for effective treatment of ADHD symptoms does not prove that deficits are the cause of symptoms Neurophysiological and Neurochemical Associations
Slide 49-

Sugar is not the cause of hyperactivity Allergic reactions and diet Possible moderating role of genetic factors may explain why food additives affect the behavior of some children Low levels of lead may be associated with ADHD symptoms The role of diet, allergy, and lead as primary causes of ADHD is minimal to nonexistent Diet, Allergy, and Lead
Slide 50-

Importance of family influences Family influences may lead to ADHD symptoms or to a greater severity of symptoms Family problems may result from interacting with a child who is difficult to manage Family conflict is likely related to the presence, persistence, or later emergence of associated oppositional and conduct disorder Family Influences
Slide 51-

Less than half of the children with ADHD receive treatment Of those who receive treatment, many discontinue prematurely The primary treatment approach combines: Stimulant medication Parent management training Educational intervention Treatment
Slide 52-

Treatments for Children with ADHD
Slide 53-

Stimulants have been used to treat ADHD since the 1930s Among the most effective stimulants are dextroamphetamine and methylphenidate May help normalize frontostriatal structural abnormalities and functional connections Effects are temporary and occur only while medication is taken; beneficial in short-term Questions surround long-term benefits and later adjustment Medication
Slide 54-

Provides parents with a variety of skills Managing the child’s oppositional and noncompliant behaviors Coping with emotional demands of raising a child with ADHD Containing the problem so it does not worsen Keeping the problem from adversely affecting other family members Parent Management Training (PMT)
Slide 55-

Parents are: Taught to understand biological basis of ADHD Given set of guiding principles Taught behavior management principles and techniques Encouraged to spend time each day sharing enjoyable activity with their child Taught how to reduce their own levels of arousal Parent Management Training (PMT) (cont’d.)
Slide 56-

Teacher and child must set realistic goals and objectives Response-cost procedures are used to reduce disruptive or off-task behaviors Many strategies are basic good teaching methods School-based interventions for ADHD have received considerable support Educational Intervention
Slide 57-

Summer treatment programs Maximize opportunities to build effective peer relations in normal settings and provides continuity with academic work so gains from school year aren’t lost Are coordinated with stimulant medication trials, PMT, social skills training, and educational interventions Intensive Interventions
Slide 58-

Family counseling and support groups Help family members develop new skills, attitudes, and ability to relate more effectively Individual counseling Helps children with ADHD deal with their problems and feelings of isolation and abnormality Helps build their sense of self-competence Additional Interventions
Slide 59-

Children with ADHD have problems that should not be minimized Each child is unique and has assets and resources that need to be recognized and supported Keeping Things in Perspective
