Downs syndrome is a developmental disorder, and is caused primarily by a commonly occurring genetic condition. The body consists of millions of cells, and each cell normally contains 46 chromosomes. An individual with Downs syndrome has one extra chromosome, 47 in total. This results in disruptions to physical development, and learning disabilities, ranging from mild to severe. Adults with Downs syndrome seem to need sameness, repetition and order throughout their daily lives; this can help to provide a secure structure and routine, which in turn can help an individual to communicate personal choices and preferences, and to express their personality. Individuals are highly responsive to their social environment and enjoy being involved in social activities.
