  3. Contents • Clinical diagnostic steps • Diagnostic scales utilization • Recent neurorradiological diagnostic tools

  4. Clinical diagnostic steps

  5. Clinical facts-dilemmas • In clinical practice ADDH is notoriously frequent: Does it mean high prevalence or overdiagnosis? • Metilphenidate prescription rate is subsequently high Is Metilphenidate prescribed on curative purpose or just to “calm down”?

  6. Nosological illusion (?): On line Web pages • ADDH • AD disorder and hypoactivity • Hyperattentional Disorder and hyperactivity • Hyperattentional Disorder and hypoactivity • What ... the future will be?

  7. Essential diagnostic criteria • Attention Deficit • Impulsiveness • Hyperactivity Diagnostic criteria? vs. Psychopathological content?

  8. Psychopathological content /1 • Quantitative • vs. • Qualitative? • Understanding deficit • vs. • Attention deficit? • Cognitive deficit • vs. • Attention deficit? Attention Deficit

  9. Psychopathological content/2 • Quantitative • vs. • Qualitative? • Primary conduct • vs. • reactive behaviour? • Impulsiveness • vs. • aggressiveness? Impulsiveness

  10. Psychopathological content/3 • Quantitative • vs. • Qualitative? • Restlessness/nervousness • vs. • Hyperactivity? • Agitation • vs. • Hyperactivity? Hyperactivity

  11. Developmental Reactivity in Childhood • Language development and socio-cultural context dependent • Nonverbal stage: Psychomotor and corporal reactivity • Initial language stage: Body language remains and behavioural outburst appears • Stablished language stage: Emotions can be expressed through language

  12. Diagnostic scales utilization

  13. Exclusion Criteria • Mental disorder related to a medical condition predisposing to one or more symptoms • Generalized Mental Disorder presents essential or associated symptoms which are essential symptoms of less generalized disorders • Clinical practice is hierarchically above complexity, difficulty or subtleness of categorial diagnostic criteria DSM-IV, 1994, pag. 6 DSM-IV-TR, 2002, pag. 7

  14. Clinical evaluation according to categories: A call for attention • Criteria are guidelines: An specific training on its utilization is required • Criteria are a consensus: Not all possible clinical conditions are included • Diagnostic Criteria should be used as guidelines according to clinical thinking: “not to be followed as a recipes in cook book” DSM-IV, 1994, pag. XXII; DSM-IV-TR, 2002, pag. XXXI

  15. Assessing scales: Diagnostic utilization • Aimed at assessing signs and symptoms • Based on pre-established category criteria • Not replacing clinical observation • They are ancillary tests but not driving directly to a diagnosis • They are more valuables when clinical features are collected within the clinical interview process and translated to scales by clinical staff soon after of the clinical interview • Conner’s and Taylor’s are mostly used

  16. Selected clinical cases

  17. Clinical cases profile • Boy • Average age:10 years • Main diagnosis: ADDH • Diagnosis based mostly on clinical description/categories • Current treatment: Methylphenidate (prescribed doses slightly lower than recommended)

  18. Recent neurorradiological diagnostic tools

  19. Attention Deficit Disorder without Hyperactivity • Boy, 8 years • Right handed • Normal pregnancy and delivery, normal psychomotor and language development • Aggressive behaviour toward parents • EEG: Normal • Brain CT: Normal • Blood and biochemistry tests: Normal • Visual SPAN, DD= 6; DI= 2 • DD=4; DI=4 • STROP, Interf.= -3.9 • Poor parental discipline and monitoring • Inability to perform basic routine home and school activities (school failure) • Treatment: Not treatment at the moment but p1reviously MPh and Nemactyl

  20. LEFT HEMISPHERE RIGHT HEMISPHFERE Bipolar receptor difference: 500-700 milliseconds Test: CPT Increased cingular activity By courtesy of Prof. T. Ortiz (UCM)

  21. Test: Response inhibition (500-700 msec.HD) Increased cingular activity By courtesy of Prof. T. Ortiz (UCM)

  22. ADDH • Boy, 7 years of age • Background:Intense hyperactivity evidenced at 3 years of age • Right handed • WISC-R: • IQ= 95 • MR= 100 • VR= 92 • SPAN VISUAL DD=7; DI=5 • DD=3; DI= 2 • Stroop, Interf.= -9,78 • The basic routines pattern seems to be very variable: Ranging from total supervision to almost independent life • The child shows relevant difficulties to: • Inhibitdisruptive behaviour • Accept behaviour supervision • Treatment: Methylphenidate 10 mg/day

  23. ADDH (Response inhibition test)(500-700 mseg HD) Decreased cingular activity By courtesy of Prof. T. Ortiz (UCM)

  24. ADDH PET-FDG: Bilateral talamic hypometabolism Preserved cortex MR: Normal By courtesy of Dr. A. Maldonado (Complutense PET Center)

  25. Discussion/1 • Categories or dimmensions? • As a borderline developmental stage (ex.: Family relationships with poor limits and “bad upbringing”, poor family management) • As a symptom of other conditions (ex.: Cognitive delay, Personality disorder) • ADDH as an specific condition (careful and detailed neuropsychological testing) • Clinical Diagnosis or test score scales? • Psychopathological and contextual assessment • Scales score is not a diagnosis (ex.: Conner’s scales assess pharmacological treatments in childhood)

  26. Discussion/2 • Data “struggle”: USA (10-14%) vs. Europe (5-7%) • Treatment: • Give the priority to symptoms/processs evaluation and its sequence in the boy/girl background • Methylphenidate doses and timing: • Initial treatment: Four weeks • Dose prescription according to recommendations (0.5-1 mgr/Kg weight/day) • A breakfast and lunch dose • From Monday to fryday (schedule days) • Treatment term: 2-5 school years • Individual Psychopedagogical support • Family Councelling • Longitudinal follow-up: Continuity vs. discontinuity? ... What about?
