Behavioral & Developmental Pediatrics Flashcards
What are the developmental domains assessed in health maintenance?
- Motor Development
- Language development
- Problem solving
- Psychosocial skills
Even if an initial screen is normal, parental concerns aboud development should not be disregarded because…
Many developmental screening tests lack sensitivity
What is a developmental quotient? What do their values indicate?
Developmental quotient (DQ) = (developmental age)/(chronologic age) x 100
- DQ > 85: normal

- DQ 70-85: close follow-up warranted
When do primitive reflexes (moro reflex) appear? When do they disappear?
Present at birth and usually disappear between 3 and 6 months of age
What does it mean when an infant shows stronger and more-sustained primitive reflexes?
Central nervous system injury
Infants with CNS damage may have delayed development of ________ reactions
postural
Gross Motor Milestones
- Birth:
- 2 months:
- 4 months:
- Birth: Turns head to side
- 2 months: Lifts head when lying prone, head lag when pulled from supine position
- 4 months: Rolls over, no head lag, pushes chest up with arms
Gross Motor Milestones
- 6 months:
- 9 months:
- 12 months:
- 6 months: Sits alone, leads with head when pulled from supine position
- 9 months: Pulls to stand, cruises
- 12 months: Walks
An infant’s fine motor skills progress from control over ______ muscles to control over ______ muscles
Proximal; Distal
What are the primitive reflexes?
- Moro reflex: symmetric abduction and extension of arms with trunk extension
- Hand grasp: reflex grasp of any object placed in palm
- Atonic neck reflex: If head is turned to one side, arms and legs extend on same side and flex on the opposite
- Rooting reflex: turning of head toward same side as stimulus when corner of infant’s mouth is stimulated
What are the postural reactions, and when do they start?
- Head righting: ability to keep head vertical despite body being tilted (4-6 months)
- Parachute: Outstretched arms and legs when body is abruptly moved head first in downward direction (8-9 months)
What are the fine motor milestones?
- Birth:
- 3-4 months:
- 4-5 months:
- Birth: Keeps hands tightly fisted
- 3-4 months: Brings hands together to midline and then to mouth
- 4-5 months: Reaches for objects
Fine motor milestones:
- 6-7 months:
- 9 months:
- 12 months:
- 6-7 months: Rakes object with whole hand; transfers object from hand to hand
- 9 months: Uses immature pincer (ability to hold small object between thumb and index finger)
12 months: Uses mature pincer (between thumb and tip of index finger)
What is the earliest sign of neuromotor problems in development?
Persistent fisting beyond 3 months of age
What red flags in motor development indicate spasticity?
Early rolling over, early pulling to a stand instead of sitting, and persistent toe walking
Early hand dominance (before 18 months of age) may be a sign of…
weakness in the opposite upper extremity associated with hemiparesis
Delays in ______ development are more common than delays in other domains
language
When is the window of opportunity for optimal language acquisition?
first 2 years of life
What is the difference between language and speech?
- Language: refers to the ability to communicate with symbols
- Speech: The vocal expression of language
At what age are cooing and musical sounds expected?
2-3 months
At what age is there babbling? When are words first used?
6 months: babbling
12 months: 1-3 words (mama, dada)
By 18 months, a child should know __ - __ words
By 3 years, more than __% of the child’s speech should be intelligible
By 18 months, a child should know 20-50 words
By 3 years, more than 75% of the child’s speech should be intelligible
What is the prespeech period?
0-10 months: expressive language consists of musical like vowel sounds (cooing) and adding consonants to the vowel sounds; receptive language is characterized by increasing ability to localize sounds
What is the naming period?
10-18 months: Characterized by the infant’s understanding that people have names and objects have labels
What is the word combination period?
18-24 months: Early word combinations are “telegraphic” (no prepositions, pronouns, articles)
Intellecutal development depends on what three things?
- Attention
- Information processing
- Memory
What is the single best indicator of intellectual potential?
Language
What are the 5 stages of cognitive development? When does each start?
- Sensorimotor period - Physical manipulation of objects (birth to 2 years)
- Stage of functional play (begins at about 1 year of age)
- Stage of imaginitve play (24-30 months)
- Concrete thinking (preschool and early elementary years)
- Abstract thinking (Adolescent years)
Object permanence develops at about _ months
As a result of this ability to maintain an image of a person ______ _______ develops when a loved one leaves the room
9 months; separation anxiety
What is magical thinking?
A normal state of mind during the preschool toddler years when a child assumes inanimate objects are alive and have feelings
What are some red flags in cognitive development?
- Skills significantly delayed in language and problem solving: mental retardation
- Language skills delayed: hearing impairment of communication disorder
- Problem solving skills delayed: Visual or fine motor problems
- Discrepance between language and problem solving skills: Learning disabilities
Social skill milestones in order include…
- Attachment
- A sense of independence
- Social play
What is cerebral palsy?
A group of static (nonprogressive) encephalopathies caused by injury to the developing brain in which motor function is primarily affected
How is cerebral palsy diagnosed?
Repeated neurodevelopmental examinations
- Increasing tone or spasticity
- Hypotonia
- Assymetric reflexes or movement
- Abnormal primitive reflexes or emergence of postural responses
- Maternal risk factors for cerebral palsy:
- Prenatal:
- Perinatal:
- Maternal: multiple gestation; preterm labor
- Prenatal: intrauterine growth retardation; congenital malformations, infections (TORCH)
- Perinatal: Prolonged, traumatic delivery; Apgar score < 3 at 15 minutes; Premature or postdates
What are postnatal risk factors for cerebral palsy?
- Hypoxic-ischemic encephalopathy
- Intraventricular hemorrhage
- Trauma
- Kernicterus
What are the two types of cerebral palsy?
Spastic cerebral palsy; Extrapyramidal cerebral palsy
What are the three types of spastic cerebral palsy?
- Spastic diplegia: involves lower extremities > upper extremities or face
- Spastic hemiplegia: unilateral spastic motor weakness
- Spastic quadriplegia: motor involvement of head, neck, and all four limbs
What is extrapyramidal cerebral palsy (athetoid cerebral palsy)?
Patients have problems modulating control of the face, trunk, and extremities, often writhing; significant oral motor involvement often occurs
Define mental retardation
Significantly subaverage general intellectual functioning associated with deficits in adaptive behavior such as self care, social skills, work, and leisure
