(p. 162) Before discussing the anxiety disorders, it is important to consider the concept of anxiety and its heterogeneity. Anxiety refers to multiple mental and physiological phenomena, including a person’s conscious state of worry over a future unwanted event, or fear of an actual situation. Anxiety and fear are closely related.

Autism has been reported in untreated patients with phenylketonuria. The authors aimed to explore autism in 15 Tunisian and 4 Algerian phenylketonuria patients, and report their clinical, biochemical and molecular peculiarities. The Childhood Autism Rating Scale and the Autism Diagnostic Interview–Revised were used for the diagnosis of autism.

Behaviorism is very much on the nurture side of the debate as it argues that our behavior is learnt from the environment. The social learning theory is also on the nurture side because it argues that we learn our behavior from role models in our environment.

Background: Phenylketonuria (PKU) considered to be a rare inborn error of metabolism, but one of the commonest causes of mental retardation when untreated. Objectives: The present study has been.

Phenylketonuria is a genetic disorder inherited from a person’s parents. It is due to mutations in the PAH gene which results in low levels of the enzyme phenylalanine hydroxylase. This results in the buildup of dietary phenylalanine to potentially toxic levels.
