15 The mind
Examination
Organic disease from constipation to brain tumours may present with problematic behaviour. On occasion, the abnormal behaviour leads to physical ill health, e.g. anorexia nervosa. A child’s physical features may give clues about their behaviour. For example, a number of chromosomal disorders, such as fragile X, Prader–Willi and Klinefelter syndromes (see Chapter 18, Table 18.2) have particular behavioural characteristics. If necessary, any investigations should ideally be done at the beginning to identify physical health problems.
Tantrums
What are tantrums?
Toddlers like being ‘in charge’ (as can be seen in Case 15.1). This desire is often thwarted by their abilities and the limits set by their parents. For example, 2-year-olds may want to eat their meal with their parents’ cutlery although they do not have the fine motor skills to do so, or their parents may prevent them from adding tomato sauce to their ice cream, for example.
Hyperactivity
What is attention deficit hyperactivity disorder?
The girl’s condition in Case 15.2 is an example of attention deficit hyperactivity disorder (ADHD) which is a triad of inattention, impulsivity and hyperactivity, with impairment of social or educational functioning as a consequence. In order to make the diagnosis, these difficulties should be seen before the age of 7 years and usually much younger. The patterns of behaviour need to be chronic (of at least 6 months’ duration), pervasive – i.e. they affect the child in two or more situations, such as at home, at school, or with grandparents and friends – and cause functional impairment.
What is not ADHD?
The history should not only focus on identifying the key behaviours but should highlight other biological or psychiatric explanations that might mimic these behaviours (see Box 15.1).
