Since the brain is such a complex organ, there are a number of genes involved in its development. Consequently, there are a number of genetic causes of mental retardation. Most identifiable causes of severe mental retardation (defined as an IQ of 50 or less) originate from genetic disorders. Up to 60 percent of severe mental retardation can be attributed to genetic causes making it the most common cause in cases of severe mental retardation (Moser, 1995). People with mild mental retardation (defined as an IQ between 50 and 70-75) are not as likely to inherit mental retardation due to their genetic make-up as are people with severe mental retardation. People with mild mental retardation are more likely to have the condition due to environmental factors, such as nutritional state, personal health habits, socioeconomic level, access to health care and exposure to pollutants and chemicals, rather than acquiring the condition genetically (Nelson-Anderson & Waters, 1995). Two of the most common genetically transmitted forms of mental retardation include Down syndrome (a chromosomal disorder) and fragile X syndrome (a single-gene disorder). The last week i have just completed my dissertation on mental retardation by using buy custom essays online. It was very nice experience to me,i have refferd many resourses for this... Anyway thank you for sharing a good thread here.. Have a good day

since the mind is this type of complicated organ, there are a number of genes involved in its improvement. therefore, there are some of genetic causes of mental retardation. maximum identifiable causes of excessive mental retardation (defined as an IQ of 50 or less) originate from genetic disorders. up to 60 percentage of extreme mental retardation may be attributed to genetic reasons making it the maximum not unusual reason in cases of extreme intellectual retardation (Moser, 1995). humans with mild intellectual retardation (defined as an IQ between 50 and 70-seventy five) aren't as probably to inherit mental retardation due to their genetic make-up as are humans with intense intellectual retardation. people with moderate intellectual retardation are more likely to have the circumstance due to environmental factors, together with dietary country, non-public health behavior, socioeconomic degree, get entry to to health care and publicity to pollution and chemicals, in place of acquiring the circumstance genetically (Nelson-Anderson & Waters, 1995). of the most common genetically transmitted varieties of intellectual retardation encompass Down syndrome (a chromosomal disorder) and fragile X syndrome (a unmarried-gene sickness). The last week i have simply completed my dissertation on intellectual retardation through using buy academic paper online. It become very best enjoy to me,i've refferd many resourses for this... anyway thanks for sharing a great thread right here.. Have a good day smiling face
