Medical Issues Flashcards
How do we acquire disabilities?
- Prenatally (before)
- Perinatally (during)
- Postnatally (after)
What affects us prenatally?
- alcohol, drugs, smoking
- leads to low birth weight
What affects us perinatally?
- anoxia (low oxygen)
- prolonged labor
- injury from medical instruments (forceps)
What affects us postnatally?
- head injuries
- poor nutrition
- environmental factors (lead poisoning)
What does the right and left hemisphere of the brain control?
rt- non-verbal stimuli
lf- language-related stimuli
What are the Four Hemispheric Lobes/functions?
- Temporal: auditory
- Frontal: abstract thinking, gross motor, speech (Broca’s Area)
- Parietal: tactile sensations (Wernicke’s Area)
- Occipital: vision/perception
What does Postmortem show us?
- abnormalities in planum temporale
- smaller brain with fewer cells
What do Genetics of LD show us?
- inheritability
- twin studies
What does computed tomography(CT) show us?
-computerized x-rays
What does Position-emission tomography (PET) show us?
- measures brain at work
- blood flow to regions highlighted by radioactive compounds
What do Functional Magnetic Resonance Imaging (FMRI) show us?
-view regions of the brain during activity
What are Soft Signs?
- possible indications of developmental delay in young children
- need to be monitored
- DOES NOT MEAN IT IS A DISABILITY
What are soft sign tests for Visual-motor skills?
copying various geometric designs
What are soft sign tests for Fine Motor skills?
finger agnosia (which is being touched) dexterity
What are soft sign tests for Gross Motor skills?
hopping
tandem walking
standing on one foot
