What Childhood Mental Disorders and Illnesses can children be affected by?

  • Intellectual disabilities are a specific type of disability that is caused by limited mental capacity (intelligence). These limitations make it difficult for someone to care for themselves without additional support.
  • Children that appear to have extremely poor coordination that interferes with achievement or age-appropriate activities of daily living (e.g., walking, playing catch, etc) may be suffering from a Motor Skills Disorder.
  • Children or adolescents may be diagnosed with a Learning Disorder when their achievement on standardized tests in reading, mathematics, or written expression is significantly below what is expected for their age, schooling, or level of intelligence.
  • Communication Disorders are problems of childhood that affect learning, language, and/or speech.
  • A child who demonstrates severe and persistent difficulties in several areas of development (social interactions, language and communication, repetitive and stereotypical behavior) may be affected by a Pervasive Development Disorder.
  • Children who have chronic difficulties in maintaining attentional focus, completing work, being impulsive, or repeatedly engage in antisocial behaviors such as lying and cheating may have one or more Attention-Deficit and Disruptive Behavior Disorders. The disorders in this category include Conduct Disorder, Attention-Deficit Hyperactivity Disorder, and Oppositional Defiant Disorder.
  • Disorders in the "Feeding and Eating Disorders of Infancy or Early Childhood" category include Pica, Rumination Disorder, and Feeding Disorder of Infancy or Early Childhood. 
  • Elimination disorders (Enuresis and Encopresis) occur when children who are otherwise old enough to eliminate waste appropriately repeatedly void feces or urine in inappropriate places or at inappropriate times.
  • Selective Mutism occurs when a child persistently fails to speak in certain social situations where speaking is expected.
  • Children and adolescents affected by Separation Anxiety Disorder become severely distressed when separated from their familiar surroundings and caregivers.
  • In Reactive Attachment Disorder, children develop abnormal relationships with caregivers that are described, in the language of the DSM criteria for the disorder as either Inhibited or Disinhibited.
  • Children with Stereotypic Movement Disorder can't seem to stop themselves from engaging in repetitive, and seeming nonfunctional motor behavior.
  • Tic Disorders are diagnosed when people have chronic (i.e., repeated across time) motor and vocal tics that interfere with their daily activities.
