Developmental disorder


Developmental disorder: One of several disorders that interrupt normal development in childhood. They may affect a single area of development (specific developmental disorders) or several (pervasive developmental disorders). With early intervention, most specific developmental disorders can be accommodated and overcome. Early intervention is absolutely essential for pervasive developmental disorders, many of which will respond to an aggressive approach that may combine speech therapy, occupational therapy, physical therapy, behavior modification techniques, play therapy, and in some cases medication.

  • Developmental dyspraxia

    Developmental dyspraxia: A pattern of delayed, uneven, or aberrant development of physical abilities during childhood development. The physical abilities affected may be gross or fine motor skills. Developmental dyspraxia may be seen alone or in combination with other developmental problems, particularly apraxia or dyspraxia of speech.

  • Deviated septum

    Failure of the nasal septum to be in the center of the nose and divide the nasal passages evenly. Deviation of the nasal septum may be congenital (present at birth) or acquired (occur later). The major problem it causes is airway obstruction. A deviated septum can be corrected with surgery.

  • Airway obstruction

    Airway obstruction: Partial or complete blockage of the breathing passages to the lungs. Causes include the presence of foreign matter, allergic reactions, infections, anatomical abnormalities, and trauma. Associated respiratory distress may be sudden, with only a cough for a warning. There is often agitation in the early stages. Other signs include labored, ineffective breathing, until […]
