Diagnosis and Management of ADHD
Slide 2-

ADHD Hill, P. Child & Adolescent Mental Health in Primary Care 2003; 1(1):2-4 “Attention deficit hyperactivity disorder (ADHD) is a pattern of behaviour which is the most recent in a series of American attempts to characterise inattentive restlessness as a condition. It is effectively a syndrome encompassing hyperactivity, poor concentration and marked impulsive, impatient, excitable behaviour. Most, but not all, instances are predominantly genetic in origin, with various inherited deficiencies of the dopamine neurotransmitter system.”

ADHD: Prevalence and Demographics Overall prevalence 3% to 10% in school-aged children Diagnosed in boys 3 to 4 times more often thanin girls Persists in 30% to 50% of patients into adolescence and adulthood (symptom profile may change)
Slide 5-

Neurochemical Pathophysiology of ADHD Receptors Synapse Transporter Noradrenaline Dopamine
Slide 6-

Impact of ADHD on Patientsand Family Patients Poor academic achievement Social impairment Low occupational status Increased risk of substance abuse Increased risk of injury Family Increased stress levels Increased depression Increased marital discord Changed work status
Slide 7-

Impact of ADHD onSchool Performance Poor classroom behaviour Poor academic achievement Special education requirements (tutoring and special educational programmes) School exclusion (either suspension or expulsion) Repetition of grades Failure to gain external qualifications

Impulsivity Talks excessively † Blurts out answers Cannot await turn Interrupts others Intrudes on others DSM-IV – Diagnostic and Statistical Manual, 4th Edition (American Psychiatric Association, 1994) ICD-10 – International Classification of Diseases, 10th Edition (World Health Organisation, 1993) Hyperactivity Fidgets Leaves seat in class Runs/climbs excessively Cannot play/work quietly Always ‘on the go’ Talks excessively * Inattention Does not attend Fails to finish tasks Can’t organise Avoids sustained effort Loses things, ‘forgetful’ Easily distracted * ‘Talks excessively’ is one of the DSM-IV criteria for hyperactivity but not one of the ICD-10 criteria † ‘Talks excessively’ is one of the ICD-10 criteria for impulsiveness but not one of the DSM-IV criteria Symptom Groups
Slide 15-

DSM-IV ADHD Diagnostic Criteria List of symptoms must be present for past 6 months Must have six (or more) symptoms of inattention and/or hyperactivity–impulsivity Some symptoms present before 7 years of age Some impairment from symptoms must be present in two or more settings (e.g. school and home) Significant impairment: social, academic or occupational Exclude other mental disorders
Slide 16-

DSM-IV Subtypes of ADHD Predominantly inattentive Predominantly hyperactive–impulsive Mixed/combined In partial remission Not otherwise specified (NOS)
Slide 17-

ICD-10 HKD Diagnostic Criteria Used to diagnose hyperkinetic disorder (HKD), a more severe form of ADHD List of symptoms must be present for at least six months Must have: at least six symptoms of inattention AND at least three symptoms of hyperactivity AND at least one symptom of impulsivity Onset of symptoms no later than 7 years of age Impairment of symptoms must be present in two or more settings (e.g. school and home) Significant impairment: social, academic or occupational
Slide 18-

Important Rating Tools for ADHD Conners Parent Rating Scale – assesses and monitors response to treatment IOWA Conners – measures dimensions of behaviour associated with ADHD SKAMP Measures – measures the classroom manifestation of ADHD SNAP-IV Scale – derived from descriptions in DSM-IV Continuous Performance Test (CPT) – measures the attention span in children with ADHD C-DISC – computer-assisted diagnostic interview schedule for children
Slide 19-

Therapy Options as Part of a Total Treatment Programme Behavioural treatment Medication management Combining medication/behavioural treatment Educating parents/patient about ADHD Educational support services
Slide 20-

Cunningham, Barkley. Child Dev 1979; 50: 217–224 Tools Used in Behavioural Treatment Specific strategies Reward system Time out Social reinforcement Behaviour modelling Support for parents Family and patient education Group problem-solving Sports skills Social skills training
Slide 21-

Behavioural Treatment in the Home Identify problem situations and the precipitating factors Enhance positive parent–child interactions Limit negative parent–child interactions Use cost systems to reduce problem behaviours Use time outs as punishment for serious problem behaviours
Slide 22-

Atkins, Pelham. 1992:69–88; Barkley, Cunningham. Arch Gen Psychiatry 1979; 36: 201–208 Behavioural Treatment in the Classroom Behavioural treatment in school setting similar to the approach used in home with parents Goal: Reduce inattention and disruptive behaviour Specific school accommodations: Ensure structure and predictable routines Employ cost–response token economy systems Use daily report cards Teach organisational and work/study skills
Slide 23-

Effectiveness of Behavioural Therapy Parent training is generally regarded as the most effective behavioural therapy Parent training combined with medication management increases parent acceptability of medication School-based treatment is more effective than individual strategies, however benefits are only seen during treatment programmes Individual treatment approaches have not been shown to be effective
