Weeks 1-3 Flashcards
Neuroplasticity
Brain a plastic living organism that can change structure and function depending on behaviours>reorganisation of the brain
Developmental plasticity
-adapt to social and physiological environments
-most plastic in first 1000 days
Critical periods
Periods in which an organ or system matures
Sensitive periods
-time windows when the effect of experiences of brain development=unusually profound
-shapes neural circuits
Neuroplasticity- in adolescence
-pre-frontal cortex=develops the most
-most grey matter in pre-frontal Corte during early adolescence and decreases during adolescence
-less pre-frontal cortex use
-risk taking is high b/c not developed
Sensory development
- Vision
-rapidly develops over first 6 months
-primary interest=human faces - Hearing
-starts in womb
-preference for human voice
-can distinguish between similar sounds by 1 month
Language production and comprehension
- Cooing= 2 months
- Syllables e.g. ‘ga’=3-4 months
- Reduplicative babbling e.g. ‘babababa’= 6 months
- Conversational babbling (turn-taking)=10 months
Gross motor development
- Functional head control
-2 months=maintain head control but looks down
-3 months=can lift head to 45 deg in prone
-4 months=full head control and develops arm movement in prone - Sitting
-supported sitting
-propped sitting
-independent sitting
Medical vs social models of healthcare
- Medical
-focuses on fixing the condition - Social
-disability or health issue is the result of an interaction between living with impairments and the environment e.g. physical, communication, social and attitudinal
Biopsychosocial approach
-chronic pain is caused by sensitivity of the nervous system>complex
-must retrain the brain
Principles of health
- Education
- Environment
- Exercise
- Nutrition
- Mind and emotions
- Connectedness
- Spirituality
- Sleep
Theories of human development
- Nature vs nurture
- Activity vs passivity
- Continuity vs discontinuity
- Universality vs context specificity
Childhood trauma-description
-ACEs=adverse childhood experiences>traumatic events that can have negative, long-lasting effects on HWB (physical ,emotional or sexual abuse to divorce or incarceration of a parent)
-adverse side effects on health e.g. alcoholism, obesity
Childhood trauma-impacts on brain development
-volumetric changes
-emotional neglect and physical abuse=smaller amygdala and hippocampus volumes
-volumetric changes in the pre-frontal cortex and cerebellum
Childhood trauma-impacts of child health outcomes
-impaired immune function
-poorer behaviour
Childhood trauma-impacts on adult health outcomes
-lower parent-child attachment
-T2D
-CVD risk
-inflammatory gene expression
-premature mortality
-chronic stress=toxic to developing brain and organs
-unhealthy behaviours to cope with stress
-increased chronic disease
Childhood trauma-problem of ACEs
-disproportionately impacts children living in poverty
-social determinant of health
-not only a social dilemma=responsibility as a healthcare provider
Childhood trauma-trauma-informed care
-parenting programs and policies addressing social factors e.g. substance use disorders
-social services referrals, asking about ACEs, promoting resilience
-know pathways for recovery
-acknowledge signs and symptoms
-develop a program
-prevent re-traumatization
1. Safety
2. Trustworthiness and transparency
3. Peer support
4. Collaboration and mutuality
5. Empowerment, voice and choice
6. Cultural, historical and gender issues
Primitive reflexes
-babies delivered at full term will have them
-stereotypical movement patterns in response to stimuli
Fine motor development
-use of small muscles in hands and arms to manipulate objects
-hand-eye coordination
