The Neurobiology of Mental Retardation: Fragile X Syndrome Essay

The Neurobiology of Mental Retardation breakable X SyndromeIn my previous paper, I wrote on the topic of the nature-nurture literary argument and the ways it related to the brain-equals-behavior dilemma. In this paper, I will continue this investigation into the link amidst genes and neurobiology, but I will focus in on a particular aspect of the relationship neurological sickness caused by genetic aberration. There atomic number 18 many well canvas and well documented (thought not necessarily well understood) disorders associated with the X chromosome, and a large number of these have neurobiological roots and behavioral manifestations. unriv altogethered such disease is fragile X syndrome. Fragile X syndrome is the more or less common inherited form of learning disabilities and mental retardation cognise (1). The disease shows an x-linked inheritance pattern and is characterized by a host of symptoms ranging from damage learning abilities to severe retardation and autisti c behaviors (1). An understanding of the disease is critical on several levels. Fragile X syndrome (FXS) not only bears scientific significance for the fields of molecular genetics, transmission genetics, neurophysiology, and abnormal psychology. It also provides unrivaled with a vantage point from which to view the particular set of behaviors know as mental retardation as well as those impaired by retardation who are too often stigmatized and marginalized in our society. earlier analyzing the neurobiological basis of FXS, it is pertinent to examine the genetics underlying the disease. As stated before, FXS is known to be x-linked which means that the disease will step up roughly in twice as many male cases as female. This is because males, who have only a single copy of x-linked genes which they inherit on... ... syndrome and Downs Syndrome are also forms of mental retardation, the latter of which is not even an inborn fallacy of metabolism- it is a chromosomal disorder. And yet the particular subset of behaviors in question is all called mental retardation. Thus, more cytological and neuro-imaging research must be conducted to to the full elucidate the complexities of FXS. For the time being, I think, it is safe to assume that the link between a single gene and a complex class of behaviors is safe for fragile X syndrome.
