Other Disorders in Childhood • Autistic Disorder • Infants exhibit failure to cuddle; indifference or aversion to affection of physical contact; lack of eye contact; lack of facial responsiveness; lack of socially directed smiles; fail to respond to parental voices • Asperger’s Disorder • Qualitative impairment in social interaction, accompanied by repetitive and stereotyped behaviors, interests and activities that cause clinically significant impairment in social or occupational functioning • Reactive Attachment Disorder of Infancy or Early Childhood • Markedly disturbed social relatedness, manifest by either persistent failure to respond appropriately to most social interactions or diffuse attachments
MC • Assessment reviled no exposure to alcohol • Diagnosed with • Specific learning disabilities, ADHD, ODD, Conduct disorder?
Child Presentation • Don’t behave as expected • ADHD • Conduct and oppositional • OCD • Can not regulate emotions • Worry • Anxious-avoidant • Sad • Don’t learn properly as expected for age • Head trauma • Inhibition • Depression • Do weird things • Psychosis • Tourette
Mentalhealthis a family affair 1 Ethanol is a treatment 2 Increased risk of substance use
Comprehensive Diagnostic Approach • The diagnosis should depend on a combination of physiological, behavioral, and interactional measures concordant with the clinical presentation and child’s age • Caregiver • Teacher/School • Child • Parents
Pregnancy Course and Outcome The Mother • Exposure during 1st, 2nd, 3d trimesters • Maternal infections, medical care, NVP • Perinatal complications, labor duration, mode of delivery – forceps, vacuum • Fetal distress severity and duration (O2 deprivation, cord around the neck) The Child • Neonatal infections (meningitis) • Neonatal jaundice - kernicterus • Neonatal respiratory distress, meconium aspiration, seizures • Developmental milestones
Caregivers • Confirmation of any exposure • Screening tests • Family history • mental health • genetic and developmental disorders • learning disabilities • Stability of caregivers environment • History of head trauma • Developmental history • Description of behavior at home /social situations Consider child’s age
Teacher • Academic achievement • Behavior in structured and non- structured learning contexts Child • Physical examination • Genetic evaluation • Laboratory • Psychiatric examination • Psychological assessment Consider child’s age
Parental Morbidity • Individuals with stress-related anxiety disorders, BD, depression may use drugs to control their symptoms (self medication) &/or experience greater reward associated with drug use • Depression is prior to substance abuse in women • Depressed substance FAS
Alcohol Comorbidity • Alcohol is a CNS drug • Parental psychopathology act as strong determinants of alcohol abuse Associated with polydrug use High risk of fetal exposure
FASD - ARND • Phenotypic, morphologic, cognitive and/or behavioral markers of ARND have not been established yet • The fetal/child dose effects of lesser quantities of alcohol consumption have not been elucidated • In > 90% FASD is associated with later mental health disorders
DD for ARND • Diverse forms of brain insult (e.g., trauma, toxic, genetic, metabolic, etc) may result in clinical presentations where differentiation from ARND is unattainable • In addition to alcohol use genetic (psychiatric disorders), environmental, and interpersonal factors influence the offspring’s neurodevelopmental trajectories

No specific treatment available Do we need to diagnose FASD? • Do we need a differential diagnosis? • When ethanol is the cause and when it is a confounder? • Do we need a comprehensive diagnostic approach to put the puzzle together? Should FASD be a diagnosis of exclusion? Or a diagnosis of inclusion along with other co-morbidity??!!
Why a Diagnosis is Needed • Lack of access to resources • Lack of proper interventions • Increased risk for secondary disabilities • Specific learning disorders • Mood and anxiety disorders • Mislead research
FASD • Ethanol is only oneof the factors in this multifactorialgene-environment-pharmacologic disorder • We may question the validity of this clinical picture as an exclusive end result of gestational exposure to ethanol • A multifactorial model where, in addition to alcohol, other genetic, toxic and environmental influences should be considered • More research is needed in separating the effect of alcohol from other confounders
FASD • Ethanol is a drug (maternal co morbidity) • CNS- the specific pattern of effects • ARND – (sensitive, not specific) • FAS is a marker for maternal alcohol abuse • Maternal and neonatal markers available
Neonatal Biological Markers • Hair • Meconium • FAEEs such as ethyl linoleate, laurate, stearate in the meconium of newborns • Testing is available through the Motherisk Program at The Hospital for Sick Children
Maternal Biological Markers • FAS • GGT (g-Glutamyl transpeptidase): > 0.50 mkat/L (reflects liver damage) • MCV (Mean red blood cell volume): >98 fL • CDT (Carbohydrate-deficient transferrin): positive result is above 99th percentile • WBAA (Whole blood-associated acetaldehyde): >9.0 mmol/L • Hair
Differential Diagnosis for Child Neurodevelopmental Disorder • Ethanol is only one of the factors in this multifactorial gene-environment-pharmacologic disorder. • We question the validity of a clinical picture as an exclusive end result of gestational exposure to ethanol; • We propose an expanded multifactorial model where, in addition to alcohol, other genetic, toxic and environmental influences are considered. • Informed by this multifactorial context, a suggest a comprehensive model of assessment and treatment, that recognizes the contribution of different diverse pathophysiological dimensions.
Do we need to diagnose ARND? • Do we need a differential diagnosis? • When ethanol is the cause and when it is a confounder? • Do we need a comprehensive diagnostic approach to put the puzzle together? Should ARND be a diagnosis of exclusion?
More Research Needed… • To determine dose effects • Threshold? • Continuum effect? • To separate alcohol effects from other etiological factors • To determine alcohol-related mental health problem? • To develop optimal interventions
Secondary disabilities Appear later in life as a result of complications from primary disabilities. • Mental health problems (94%) • Disruptive school experience (60%) • Trouble with law (60%) • Confinement (50%) • Inappropriate sexual behaviour (50%) • Alcohol/drug problems (30%) • Dependent living (80%) • Employment problems(80%)
