estimated world wide prevalence of ADHD
3.4%
number of children who’s ADHD symptoms persist into adulthood
50%
is ADHD genetic
highly! gene variants predicting risk fo ADHD are important for brain development, cell migration and catecholmine recepto/transporter genes.
name the non-inheriteded neurological factors associated with ADHD development
pregnancy and birth complications use of marijuana in pregnancy prematurity alcohol/tobacco exposure in utero low birth weight HIE epilepsy traumatic brain injury exposure to environmental toxins (lead, pesticides)
Differences in structure of brain of children with ADHD
structural development and functional activation of prefrontal cortex, basal ganglia, anterior cingulate cortex and cerebellum
delay in cortical maturation has been documented, (peak thickness occurs in children with ADHD at 10 years and thos without at 7 years)
ADHD screening tools validated for preschool children
Conner’s
ADHD rating scale IV
before diagnosing ADHD in preschoolers, the following is recommended
parents enroll in parent training program. can help parents develop age appropriate developmental expectations and management skills for problem behaviours
List 5 rating scales that can be used to screen ADHD in children and adolescents
Snap IV 26
Weiss functional impairment rating - parent
weiss symptom record
Caddra teacher assessment form (there is also a self rating one for adolescents)
Caddra patient adhd medication form
List DSM 5 criteria for ADHD diagnosis
- symptoms severe, persistent (onset before age 12 > 6 months), inappropriate for age and development
- Symptoms associated with impairment in academic achievement, peer and family relations and adaptive skills
- symptoms occur in 2 or more settings
- specify type of ADHD (need 5 or more)
i) comorbid (i.e. combined)
i) inattentive
iii) hyperactive-impulsive - current severity (mild, moderate, severe)
- not due to GMC or other psychotic disorder and are not explained better by other mental disorder)
List 8 conditions commonly misdiagnosed as ADHD
Learning disorder Sleep disorder Oppositional defiant disorder intellectual disability language disorder, conduct disorder, mood disorder anxiety disorder ASD Developmental coordination disorder Epilepsy (2-3 higher risk in this population to have comorbid ADHD)
rate of comorbidity with ADHD for disruptive behaviour disorders
this includes conduct and ODD which can have ADHD comorbidity in 90% of cases
anxiety and ocd disorder comorbid rate with ADHD
present in about 30% of patients with ADHD
List common comorbidities with ADHD
ODD /conduct Anxiety/OCD Bipolar disorder substance use disorder Tic disorder Developmental coordination disorder learning disorder eating disorders ASD
most common area of delay for children with ADHD and developmental coordination disorder?
Fine motor delays often most impaired area of motor performance
