Child and Adolescent Development Flashcards
a development disorder with onset prior to age 18 yrs, characterized by impairments in measured intellectual performance and adaptive skills across multiple domains
Intellectual disability disorder (IDD)
The etiology of intellectual disability maybe primarily biological, primarily psychosocial, or a combination or unknown.
“is a syndrome that represents a final common pathway produced by a variety of factors that injure the brain & affect its normal development”
Predisposing Factors for Neurodevelopment disorders
Implicated in approx 5% of the cases;
- -Inborn errors of metabolism, such as Tay-Sachs disease, phenylketonuria, and hyperglycinemia
- -Chromosomal disorders; ie. Down Syndrome and Klinefelter syndrome
- -Single gene abnormalities, ie tuberous sclerosis and neurofibromatosis
Genetic Factors
Accounts for 30% of IDD cases:
- Damages may occur in response to:
1. Toxicity assoc. with maternal ingestion of alcohol or other drugs.
2. Maternal illnesses and infections during pregnanay.
3. Complications of pregnancy, such as toxemia and uncontrolled diabetes.
Disruptions in Embryonic Development
Account for approx. 10% of cases of IDD
Can be cause by the following:
-fetal malnutrition, viral or other infections during pregnancy
-Trauma or complications of the birth process that result in deprivation of oxygen to the infant.
-Premature birth.
Pregnancy and perinatal Factors
Account for approx 5% of cases of IDD:
Cause by the following:
-Infections, such as meningitis and encephalitis
-Poisionings, such as from insecticides, medications, and lead.
-Physical traumas, such as head injuries, asphyxiation, and hyperpyrexia.
General Medical Conditions Acquired in Infancy and Childhood.
Account for between 15 and 20 % of cases with IDD
-May be attributed to
Deprivation of nurturance and social stimulation.
Impoverished environments assoc. with poor prenatal and perinatal care and inadequate nurtrition.
Severe mental disorders, such as autism spectrum disorders
Sociocultural Factors and other mental disorders
Four levels have been delineated: mild, 50-70 IQ moderate, 35-49 IQ severe, 20-34 IQ profound below 20
- Nurses must assess strengths as well as limitations in order to encourage the client to be as independent as possible.
- Family involvement in planning and implementing care.
- Family should receive info regarding scope of condition, realistic expectations, client potential, methods for modifying behavior
Application of nursing process for IDD
Characterized by a withdrawal of the child into the self and into a fantasy world of his/her own creation.
Autism Spectrum Disorder
1 in 88 children. 4.5x more likely in boys.
Onset early childhood, with symptoms persistent into adulthood.
Facts about Autism
- Abnormalities in major brain structures.
- Enlargement in temporal lobe white matter, and an increase in surface area in the temporal, frontal, and parieto-occiptial lobes.
- Role of neurotransmitters; serotonin, dopamine, and epinephrine, (currently under investigation)
Neurological Implications of Autism
Medical conditions that have been assoc. with ASD
-tuberous sclerosis, fragile X syndrome, maternal rubella, congenital hypothyroidism, phenylketonuria, Down Syndrome, neurofibromatosis, and Angelman’s syndrome.
Physiological Implications of Autism
Strong genetic factor
possible chromosomes implicated 2, 7, 15, 16 and 17
Women who suffer from asthma or allergies around the time of pregnancy are at increased risk of having a child with ASD
Genetic implicated of Autism & Prenatal influences
- Impairment in social interaction
- Impairment in communication and imaginative activity
- Restricted activities and interests
Symptomology of ASD
aimed at protection of the child from self-harm, and improvement in social functioning, verbal communication, and personal identity.
Nursing intervention for ASD
Targets behaviors such as aggression, deliberate self-injury, temper tantrums, and quickly changing moods.
1. risperidone (Risperdal. in children and adolescents 5 to 16yrs old)
-dosage based on weight and clinical response
-common side effects: drowsiness, increased appetite, nasal congestion, fatigue, constipation, drooling, dizziness, and weight gain.
2. Aripiprazole (Abilify. in children 6 to 17 yr old)
-dosage is initiated at 2mg/day. possibly increased to 5mg//day at intervals of no less than 2 weeks, up to max of 15mg/day)
Common side effects: sedation, fatigue, weight gain, vomiting, somnolence, and tremor.
Possible Serious side effects, such as neuroleptic malignant syndrome, tardive dyskinesia, hyperglycemia, extrapyramidal symptoms, and diabetes.
PsychoPharmacology Intervention for ASD
Developmentally inappropriate degrees of inattention, impulsiveness, and hyperactivity.
Attention Deficit/Hyperactivity Disorder ADHD
Combined Type (meeting the criteria for both inattention and hyperactiity/impulsivity) Predominantly hyperactive/impulsive presentation
ADHD is further categorized
Abnormal levels of dopamine, norepinephrine, and possibly serotonin have been implicated.
Adhd biochemical theory influences
~Biological Influences Genetics; Chromosomal links -Biochemical theory -Anatomical influences -Prenatal, perinatal and postnatal factors ~Environmental influences -Environmental Lead -Diet factors -Psychosocial Influences -Disorganized, chaotic families -high degree of psychosocial stress, maternal mental disorder, paternal criminality, low socioeconomic status, and unstable foster care
Predisposing factors of ADHD
Alterations in specific areas of the brain have been implicated in individuals with ADHD. These areas include the prefrontal lobes, basal ganglia, caudate nucleus, globus pallidus, and cerebellum.
Anatomical Influences ADHD
Prenatal factors include maternal smoking and alcohol intake during pregnancy.
Prenatal Factors ADHD
Perinatal factors include prematurity, signs of fetal distress, prolonged labor, and perinatal asphyxia.
Perinatal Factors ADHD
cerebral palsy, seizures, and CNS trauma or infections.
Postnatal Factors ADHD
environmental lead, diet factors; including food dyes, additives, and sugar
Environmental Factors ADHD
