This essay will discuss the debate and discussion surrounding the statement ˜Is anyone normal?' A case will be made towards the belief that no-one is normal. However, the conflicting argument will also be given. To provide a focused argument in this debate the mental disorder of Attention-deficit/hyperactivity disorder (ADHD) will be used. This essay will debate that no-one is normal by looking at the influence of community and culture and the categorization of mental disorders in the DSM. However in the opposition the biological basis of mental health disorders will be outlined. Which points towards a biological existence of abnormality. As Lane (2007) writes, ˜we've narrowed healthy behaviour so dramatically that our quirks and eccentricities-the normal emotional range of adolescence and adulthood-have become problems we fear and expect drugs to fix it.'' (p87) Differences between cultures and within cultures over time mean that what is considered as desirable in one culture is often seen as abusive in other. Although the immaturity of children is a biological fact, the ways in which this immaturity is understood and made meaningful is a fact of culture (Prout and James, 1997).In western cultures, the task of rearing has become loaded with anxiety. Teachers and parents feel they must control unruly children. This cultural anxiety has provided the ideal social context for growth of ADHD (Timimi, 2009) as a social care practitioner it's important to be aware of different cultures and understand their perceptions. Mann et al (1993) states that despite attempts at standardising criteria cross cultural studies on the rating symptoms of ADHD show major and significant differences between rates from different countries. This, therefore strengthens the argument that normality is non-existent because culture shapes the perception of ADHD. The idea of normality is based on culture. People in minority communities tend to be under diagnosed and untreated for ADHD for a number of reasons among other factors such as cultural perceptions and access to health care (Elixhauser et al, 1993).on the contrary, Prevalence rates of ADHD in Thailand, Kenya and America are similar even though they are diverse cultures (Prout, 1997). Examining the DSM provides insights to the definition and classifications of disorders. ADHD has been chosen as part of the debate as it is one of the most common conditions of child and adolescent psychiatry in the world (Remschmidt, & Global ADHD working group, 2005). ADHD has often been a source of major controversy within the mental health professions as well as among the broader public as there is uncertainty about how to define this disorder. Therefore, this relates to the question of existence
