Historical view of prenatal alcohol and FASD Aristotle - 384-322 B.C. Diogenes - cir. 400 B.C. Plutarch- 45-125 A.D. Behold, thou shalt conceive and bear a son: And now, drink no wine or strong drink. Judges 13:7 Navajo tradition, women who drink crazy water when bearing a child, will give birth to a child crazy in body and mind. barrystanleywww.barrystanleyfasd.comdocstoc bstanley31

Myth - FAS is the most severe/worst form of FASD • The terms “severe / worst” need to be qualified. • Truth – • Only approximately 27% of those with FAS will have an I.Q. below 70 – often protected, with fewer secondary disabilities. • 9% of those with ARND will have an I.Q. below 70. barrystanleywww.barrystanleyfasd.comdocstoc bstanley31
Adaptive Functioning • SIB-R “- an individual’s ability to effectively meet social and community expectations for establishing personal independence, maintaining physical needs, conforming to social norms, and sustaining interpersonal relationships” • Vineland “- the performance of the daily activities required for personal and social sufficiency” barrystanleywww.barrystanleyfasd.comdocstoc bstanley31
All those individuals exposed to prenatal alcohol [FASD], FAS and ARND will have permanent inadequate adaptive functioning. Children who have not been exposed to prenatal alcohol may also have inadequate adaptive functioning, that is not permanent. barrystanleywww.barrystanleyfasd.comdocstoc bstanley31

Mounting evidence suggests that integrative processes and dynamic interactions across multiple distributed regions and systems underpin cognitive processes as diverse as visual recognition , language, cognitive control, Emotion, and social cognition”— -- “Abnormal anatomical connectivity and functioning of hub regions has been hypothesized to relate to behavioral and cognitive impairment in several neurological and psychiatric brain disorders.” [ Network hubs in the human brain.

The Brain and the development of Neurology 20th, 21st Centuries An accurate description of the human brain – the most complex terrestrial system known - Barry Stanley “A possible definition of a complex system. Acknowledged features of a complex system are the following: -- the system is composed of a large number of elements; -- the elements are often of different types and have an essential internal structure; -- the elements are related by nonlinear interactions, often of several different types; -- the system experiences inputs at several scales. But I argue that the main hallmark of complex systems is circular causality, namely, the presence of feedbacks of (macroscopic) collective properties and emergent features on the behavior of (microscopic) elements. Elements collectively modify the surroundings, which in turn exerts constraints on them and endow them with different possible states or behaviors. In complex systems, knowing the features and behavior of the single components in isolation is not sufficient to predict the behavior of the system as a whole”.

Brain Size and Cortical Thicknessand the Glial Cell 0ur Brain consists of neurons and glial cells. Neurons constitue about half the volume of the CNS and glial cells make up the rest. Glial cells provide support and protection for neurons. They are thus known as the "supporting cells" of the nervous system. The four main functions of glial cells are: to surround neurons and hold them in place, to supply nutrients and oxygen to neurons, to insulate one neuron from another, and to destroy and remove the carcasses of dead neurons (clean up). The three types of CNS supporting cells are Astrocytes, Oligodendrocytes, and Microglia. The supporting cells of the PNS are known as Schwann Cells. barrystanleywww.barrystanleyfasd.comdocstoc bstanley31

Neurotrophic Factors and Adult Neurogenesis Proteins that control the development, survival and function of nerve cells [ neurons ] They trigger the development of neurons from progenitor cells Neuronal progenitors persist in the adult brain, but die. Neurotrophic factors might be used to develop those cells for repair of damaged nerve cells. www.barrystanleyfasd.comdocstoc bstanley31

DEFINITIONS PRENATAL – Existing or Occurring Before Birth Phenotype - The observable physical or biochemical characteristics of an organism, as determined by both genetics and environment Diagnosis – The identification of the nature of a disease or injury by history, examination and laboratory data. D.N.A. – Double helix molecule Chromosomes , 46 – Storage units for DNA. Genes – Distinct portions of DNA. Determine biological characteristics. Genotype – The genetic makeup of an organism or a group of organisms. GENETICS – The study of heredity and the variation of inherited characteristics. EPIGENETICS – The study of changes in gene function [expression] That do not involve changes in DNA sequence. STEM CELL – develop into specialized cells or replenish some specialized cells- can replicate [ reproduce] indefinitiely. PROGINATOR CELL - more specialized- can only replicate a few times. Nucleic Acids – DNA and RNA Nucleotides – are what the Nucleic Acids are formed from. barrystanleywww.barrystanleyfasd.comdocstoc bstanley31
barrystanleywww.barrystanleyfasd.comdocstoc bstanley31 Genetics – D.N.A. DNA Structure The long, stringy DNA that makes up genes is spooled within chromosomes inside the nucleus of a cell. (Note that a gene would actually be a much longer stretch of DNA than what is shown here.) DNA consists of two long, twisted chains made up of nucleotides. Each nucleotide contains one base, one phosphate molecule and the sugar molecule deoxyribose. The bases in DNA nucleotides are adenine, thymine, cytosine and guanine.
