Genetic:

Down’s syndrome

A genetic factor that can affect an individuals development is a condition called Down’s syndrome. A baby inherits genetic information from its parents in the form of 46 chromosomes 23 from each of the parents. In the cases of Down syndrome this is a chromosomal disorder caused by the presence of an all or extra chromosome for a total of 47 chromosomes instead of 46. The extra genetic material disrupts the normal course of development, causing the characteristic features of Down’s syndrome. The condition can be associated with delayed physical and mental development. Down syndrome can be associated with impairment of cognitive ability and physical growth and a particular set of facial features. People that are born with down’s may be born with a variety of birth defects, they are also have an increased risk of developing medical conditions like thyroid problems, respiratory disorders and intestinal abnormalities. They also have an increased risk of suffering with hearing and visual problems. Children with this syndrome tend to have slower language skills and lower IQ. Physical characteristics of Down’s include a smaller head, small ears and a broad, flat face. Children with Down’s syndrome tend to grow at a slower rate and they tend to have delays in speech and self care skills like feeding, dressing and toilet teaching.

Foetal Alcohol syndrome

A biological factor that can affect an individual’s development is a condition known as Foetal alcohol syndrome it is a cause of developmental delay. It is caused when the mother drinks through the pregnancy. It is the term used to describe a number of foetal abnormalities which occur in the babies of women who abused alcohol during the course of pregnancy. Drinking through pregnancy can hurt the babies’ growth and cause life long physical and behavioural problems. The severity of the abnormality depends on how much the mother has drunk through pregnancy. Babies born with ...
