Child brain development

Although the human brain is formed before birth, it continues to develop for at least 20 years. Four main developmental stages are described: before birth; birth to five years; five to 10 years; and 10 to 20 years. Specific developmental skills are attained by an individual at each of these stages. Familiarization by carers and healthcare professionals of what is normal for each stage will aid in the identification of potential problems in a child's cognitive development.
