Deck 1 Flashcards
developmental quotient is calculated how?
developmental age/chronologic age
what is normal developmental quotient?
> 85 is normal, less than 70 is abnormal
primitive reflexes
present at birht
example of primitive reflec
moro reflex
when do primitive reflexes disappear?
3-6 months of age
what should you be concerned about if primitive reflexes stay?
CNS injuries
postural reaction
acquired (not present at birth)
example of postural reflex
parachute reaction
delayed development of postural reactions should make you concerned for what?
cns damage
fine motor skills progress from prox to distal or vice versa?
prox to distal
gross motor milestone at birth
turn head side to side
gross motor milestone at 2 months
lift head when lying prone; head lag when pulled from supine position
gross motor milestone at 4 months
rolls over; no head lag when pulled from supine position; pushes chest up with arms
gross motor milestone at 6 months
sits alone, leads with head when pulled from supine position
gross motor milestone at 9 months
pulls to stand; cruises
gross motor milestone at 12 months
walks
four primitive reflexes
moro, hand grasp, atonic neck reflex (fencer); rooting
two postural reactions
head righting, parachute
moro reflex- what is it, when does it appear and when does it disappear
appears at birth and disappears at 3 months
hand grasp
appears at birth and disappears at 1-3 months
atonic neck (fencer) reflex
appears at 2-4 weeks and disappears at 6 months
rooting reflex
appears at birth and disappears at 6 months
head righting
ability to keep head vertical despite body being tilted; appears at 4-6 months and persists
parachute
8-9 months appears and then persists
fine motor milestone at birth
keeps hands tightly fisted
fine motor milestone 3-4 months
brings hands together to midline and then to mouth
fine motor milestone at 4-5 months
reaches for objects
fine motor milestone at 6-7 months
rakes object with whole hand; transfers object from hand to hand
fine motor milestone at 9 months
uses immature pincer (bt thumb and index finger)
fine motor milestone 12 months
uses mature pincer (bt thumb and tip of index finger)
when does the infant learn to use objects as tools (building blocks)?
during the second year of life
what is often the earlies sign of neuromotor problems?
persistent fisting beyond 3 months of age
what would early rolling over, early pulling to a stand instead of sitting, persistent toe walking indicate?
spasticity
early hand dominance
before 18 months of age
what can early hand dominance tell us?
sign of weakness of the opposite upper extremity associated with hemiparesis
when is optimal language development?
first two years of life
what are the periods of speech development?
prespeech (0-10 months); naming (10-18 months); word combination (18-24 months)
when, relative to when they say their first word, are infants able to combine words?
6-8 months after their first word
basic language milestone at birth
attunes to human voice; develops differential recognition of parents’ voices
basic language milestone at 2-3 months
cooing, musical sounds
basic language milestone at 6 months
babbling (ba-ba-ba, da-da-da)
basic language milestone at 9-12 months
jargoning, begins using mama, dada (nonspecific)
basic language milestone at 12 months
1-3 words, mama and dada (specific)
basic language milestone at 18 months
20-50 words; beginning to use two word phrases
basic language at 2 years
two word telegraphic sentences (mommy come); 25-50% of child’s speech should be intelligible
basic language milestone at 3 years
three word sentense; 75% intelligible
when is the “sensorimotor period”?
birth to age 2
when is functional play (using a toy telephone as a telephone), i.e. recognizing objects and associates them with their function
begins at 1 year
when does imaginitive play begin
24-30 months
when does concrete thinking start?
preschool
when does abstract thinking start?
adolescence
when does object permanence develop
9 months, think sep anxiety at this time too
when does separation anxiety develop?
6-18 months
when does cause and effect develop?
9-15 monhs
when is parallel play? Social play?
parallel during first 2 years and social at about 3 years
cerebral palsy
injury to the brain during development, such that motor function is primarily affected; intelligence can be normal or can not be; lots of other associated things like seizures, cognitive deficits, mental retardation, learning disabilities, sensory loss, and visual and auditory d
what is prevalence of cerebral palsy?
0.2-0.5%
How do you dx cerebral palsy?
repeated neurodevelopmental exams showing increased tone or spasticity, hypotonia, asym reflexes or movement disorder, or abnormal patterns in disappearance of reflexes or emergence of postural responsess
two types of cerebral palsy
spastic, extrapyramidal,
spastic diplegia cerebral palsy
one of the three types of spastic cerebral palsy; involves the lower extremities more than the upper extremities or face
maternal risk factors for cerebral palsy
multiple gestation, preterm labor
prenatal risk factors for cerebral palsy
intrauterine growth retardation, congenital malformatios, TORCH infections
extrapyramidal cerebral palsy
patients have trouble controlling the face, trunk, extremities, often writhing. Signif oral motor involvement occurs
mental retardation
significant subaverage intellectual functioning in adaptive behavior; it is manifested before 18 yo
scissoring may be a sign of what?
spastic diplegia
early hand dominance can be a sign of what?
spastic hemiplegia
extrapyramidal
involuntary reflexes
athetoid movements
slow involuntary convoluted writhing movements; seen in extrapyramidal cerebral palsy
kernicterus
bilirubin-induced brain dysfunction;
mild retardation IQ
55-69
moderate retardation
40-54
severe retardatn
25-39
profound mental retardation
less than 25
the most common cause of learning disability
idiopathic
pervasive developmental disorder
spectrum of disabilities affecting multiple developmental areas, with a wide range of severity
what is the prototypical pervasive developmental disorder (PDD)
autism
when is onset for autism
prior to 3 years
echolalia
repetitive words and phrases, seen in kids with autism
difference between autism and aspergers
autism is more severe; in aspergers you don’t see signif language delay
how heritable is ADHD?
30-50% of affected chilren have a first degree relative with ADHD
