Childhood disorders
Mental disorders among children are described as serious changes in the way children typically learn, behave, or handle their emotions, which cause distress and problems getting through the day. There are a great diversity of childhood disorder forms and causes. Some of these disorders are primarily disorders of the brain, while others are more behavioral in nature. Despite how common they may be, childhood disorders are not part of the normal developmental process that children are expected to go through. The diagnostic criteria for childhood mental disorders requires that children's behavior and/or development deviates from normal age-appropriate behavior and/or development, so understanding normal child development is important. For this reason, you might want to read over our extensive material concerning normal childhood development. Understanding normal developmental milestones for different ages puts you in a better position to understand why disordered behavior is considered abnormal. Common childhood mental illnesses and developmental disorders include Depression, Bipolar Disorder and Anxiety Disorders, Autism and similar Pervasive Developmental Disorders, Attention Deficit and Hyperactivity Disorder, Learning Disabilities, Adjustment Disorders, Oppositional Defiant Disorder, and Conduct Disorder.
