Understanding a Child's Problems is the First Step to Helping Them

Learn about different types of developmental disorders, behavioural disorders and learning disorders and their impact on children and their families. If you work with children in a caring capacity then this course is a must to enhance your knowledge of childhood mental health.

Developmental disorders include pervasive developmental disorders such as autism spectrum disorder (which now includes Asperger's syndrome) as well as Rett's disorder and childhood disintegrative disorder. Each have their own range of signs and symptoms, treatments and possible causes. Behavioural disorders include different types of attention and hyperactivity disorders along with conduct disorders like oppositional defiant disorder. Learning disorders are specific developmental disorders, such as reading disorder. There is some controversy over their inclusion as mental health disorders since a child can have one problem such as dyslexia yet be otherwise 'normal'.

The implications of a developmental disorder can be very significant in later life; if undetected and not responded to. Often though; what might potentially be a major problem in later life can be avoided through the simple act of becoming aware and responding early in life.

This course includes definitions of the aforementioned groups of disorder as well as motor and communication disorders. Take the course to learn how to identify the signs, symptoms and treatments for these different classes of childhood disorder.

The course is ideal for students of health sciences, psychology and counselling and will add to the knowledge of professionals working in related fields.

Various factors may contribute to the onset of developmental disorders and these are not always easy to define. For instance, learning disabilities are thought to have many different underlying causal factors and a number of pathological processes are thought to contribute to dysfunction of the central nervous system. Other conditions may have a range of aetiologies. As with adult mental health conditions the causes of childhood disorders are often many and include both environmental and hereditary factors, some of which may be as follows:

1) Genetic Factors
There is some indication that genetics may play a role in the onset of childhood disorders. Certainly, those born to parents with mental health disorders may have a slightly higher risk but it usually depends on their interactions with the environment as to whether these genetic influences are expressed.

Some studies have suggested that genetic factors may have a greater influence in behavioural and emotional disorders, and the psychological traits which can lead to development of these types of disorder. However, sometimes the expression of a disorder may include characteristics of other disorders and sometimes a child may have several different disorders.

Indirect genetic influences may also affect the development of disorders in those predisposed to them. For instance, intelligence and temperament may influence to what degree events are interpreted as being stressful by the child. Infants who respond to new stimuli by withdrawing, slowly responding, or through exaggerated behavioural responses may be more prone to the development of childhood disorders than those who show interest and respond quickly, and exhibit a moderate behavioural response.   

2) Physical Factors
Many different forms of physical illness can bring about childhood disorders and related problems.  Examples include pregnancy-related learning disabilities e.g. foetal alcohol syndrome, issues due to hypoxia at birth, and conditions that can occur due to a general medical condition e.g. brain damage, childhood cancer, meningitis, etc.

The most prevalent physical factor in childhood disorders is brain disorder. Around one third of children with a brain disorder will also have a psychological disorder compared to around 12% of those with a physical illness.

Children with a brain injury are more likely to develop a psychological disorder if they encounter unfavourable psychosocial influences. The likelihood of disorders associated with brain damage seems to increase with severity rather than the location of the injury.

3) Environmental Factors
Many different environmental factors can influence the expression of childhood disorders. These include:
  • Family relations - children thrive on love, security, warmth, support, and consistent and constructive discipline. Steady and regular interactions are known to help develop secure attachments and trust in infants. Parental conflict, poor family relationships and long periods of separation from parents may contribute to mental health issues. Separation anxiety, depression, and delinquency are associated with extended absences of the primary caregiver. It can lead to further problems if the parent avoids attachments when in the presence of the infant, or demonstrates inconsistency in their attachments.
  • Family home - the risk of mental health issues is increased in children who live in overcrowded housing, have low socioeconomic status, have a parent with a mental health disorder, and who are placed in care. Physical, sexual, and emotional abuse and neglect are also strong risk factors for mental health problems in children. The more risk factors present the greater the possibility of mental health issues, though children with just one risk factor will not have a rate of disorders significantly higher than those with no risk factors present.    
  • Parental mental health - the presence of a mental health disorder in the parents can affect the mental health of the child, especially if the mother is ill and she is the primary caregiver. In particular, parents with depression may neglect their children and those with schizophrenia might not respond to their children's emotional needs. Children of parents with mental health conditions may have difficulties with social adjustment and be more disruptive. Parents with alcohol and drug related mental health issues may not offer suitable levels of care to their children setting them at a disadvantage.
  • Divorce or death of parents - divorce would seem to have a greater impact on children's mental health than where parents in conflict remain together. In particular the first 12-18 months seems to be a period of high risk. Thereafter, long term effects of divorce are less clear. Death of a parent may result in anxiety related disorders in younger children and depression and conduct disorders in children aged 5 years and older.     
  • Schooling - there is some evidence that pupils who receive praise and encouragement from their teachers and who are given responsibilities tend to be less prone to psychological disorders. Bullying at school and cyber-bullying are also known to cause acute stress to victims, which can influence the onset of problems - though the long term impact is not fully understood.
  • Community - the local community may also pose specific risk factors for a child's mental health. In particular, poorer mental health outcomes are associated with overcrowding, lack of community support and involvement, poor amenities, lack of areas to play, limited access to health services.
