Development Flashcards
Moro, rooting + grasp reflex - what is it, when does it appear + when does it go?
Moro = sudden extension of head causes symmetrical extension then flexion of hands, present at birth, disappears 3-4 months
Rooting = turns head towards a stroke of the cheek. Present at birth, disappears at 4 months
Grasp = flexion of fingers when object is in palm
Tonic neck reflex, labyrinthine righting + postural support reflex - when does it appear + when does it leave?
Tonic neck = lying supine, infant adopts outstretched arm to side which head turns
Present at 1 month, integrated by 4 months
Labyrinthine righting = head moves in opposite direction to which body is tilted
Present at birth, integrates within a few months
Postural support/ stepping = when upright, legs take weight and bounce
Present at birth, disappears at 5-6 months
Lateral propping + parachute reflex
Lateral propping = when sitting, arm extends on side to which child falls
Parachute = when upside down, arms extend
6 week developmental milestones
Head lag, head in line when held
Fixes + follows object through 90’
Startles to loud noise, cries/ coos
Smiles
6 months developmental milestones
Sits without support, rolls front to back, grasps feet
Transfers objects between hands, mouths
Turns to voice, babbles
Finger feeds, laughs, holds bottle
1 year developmental milestones
Stands independently, cruises around
Pincer grip, bangs cubes
1-2 words, understands name
Drinks from cup, waves, empties cupboards
15 months developmental milestones
Broad based gate, pushes wheeled toy
Palmer grasp of pencil, random scribble , builds tower of 2, follows toy pulled 3m away
2-6 words, understands simple commands
Feeds self with spoon, can help dressing, indicates wants without crying
2 years developmental milestones
Kicks ball, climbs furniture
Circular scribble, tower of 6, turns pages
50+ words, joins 2 words, 2 step request understood
Won’t share, plays near but not with others
Red flag ages for smiling, not rolling over, unable to sit unsupported
Smiling = 6 weeks Not rolling over = 6 months Unable to sit unsupported = 9 months
Red flag ages for being unable to crawl or walk
Crawling = 12 months Walking = 18 months
Types of squint
Concomintant Paralytic
What is a concomintant squint?
Refractive error - treat with glasses Common with neurodevelopmental delay Squinting eye turns inwards (convergent) Squint is constant in all directions of gaze
What is a paralytic squint?
Varies with gaze direction due to paralysis of motor nerves (LR6 SO4) Possibility of SOL
RF for squints
Low birth weight Preterms Neuromuscular disorders Brain or eye tumours Infections
How to diagnose squints
Corneal light reflex test - if light reflection is in different positions Cover test - when fixing eye is covered, squinting eye moves to take up fixation
ASD S+S
Impaired social interaction Speech + language disorder Imposition of routines with ritualistic + repetitive behaviour
Genetic causes of blindness
Cataracts Albinism Retinal dystrophy Retinoblastoma
Antenatal + perinatal causes of blindness
Congenital infection Retinopathy of prematurity Cerebral damage Optic nerve hypoplasia
Postnatal causes of blindness
Infection JIA Vit A deficiency
Types of deafness
Sensorineural = lesion in cochlea or auditory nerve, present at birth Conductive = abnormalities of ear canal or middle ear, usually due to OME
