Document Summary
Most sensitive to prenatal alcohol exposure > gava alcohol exposure facial abnormalities mild, moderate to sever categorisations within that 10th percentile fewer folds in the brain less neural connections cognitive and behavioral dysfunctions and impairments. Alcohol is a teratogen, number one preventable neurological impairment. [knowingly] drinking while pregnant as child neglect/abuse? (abel, 1984) Fas first described in the research literature in 1973; the term fasd coined ~2003. 1:1000 live births (estimates vary a lot) Characterised impairments: prenatal/postnatal growth issues, cns dysfunction. 10th percentile (or less) in high or weight. Cerebellum and corpus callosm (information processing difficult, hard to solve problems) facial hysmorphology. Groove between nose and upper lip flattens. Meconium (child"s first poop) - blocks the child"s anus > can be analysed to measure. 10 weeks: massa commisurassi forms between hemispheres. Axons then cross this bridge to form the corpus callosum. Motor functions and higher level reasoning and cognition are at the front.
