Pervasive Developmental Disorders Flashcards
Which pervasive developmental disorder is described below?
Complex neurological spectrum of disorders
Now considered to be a biologic rather than psychological disorder, more related to mental retardation
4x more prevalent in boys
Impairments in social interaction, communication, and imaginative play
Autism
Signs of autism are apparent prior to what age?
Apparent before age 3
Autism is more prevalent in which sex and by how much?
4x more prevalent in boys
What is the cause of autism?
There are no definitive culprits that have been identified,
Thought to have a highly genetic basis with possible environmental factors
List some signs/symptoms of autism
Markedly impaired eye contact
Failure to develop peer relationships
Not seeking to share enjoyment or interests
Lack of social or emotional reciprocity
Delayed or absent spoken language without attempt to compensate with gestures or mime
Repetitive language
May also exhibit sensory-seeking or avoidant behavior
Inability to initiate and sustain conversation
Lack of spontaneous make believe play appropriate for developmental level
Repetitive motor mannerisms
Preoccupation with parts of objects
Inflexible adherence to rigid routines
Tantrums set off by noise or changes in routine
Hypersensitivity to stimulation (visual, auditory)
Strong fixations to objects or restricted interests (“little professor”)
Comorbid mental retardation or seizure disorder
What is the hallmark sign/symptom for autism?
hand flapping = hallmark
What is a screening tool for autism?
MCHAT
When is the MCHAT administered?
Administered between 16-30 months
Usually at 18 months well child check
List some differential diagnoses to consider if suspect for autism
Rett syndrome
Fragile X syndrome
Angelman syndrome
Turner syndrome
William syndrome
Asperger’s syndrome
Pervasive developmental disorder NOS (don’t meet criteria for autism or are still very young for diagnosis)
Childhood disintegrative disorder
What are the goals in managing of autism?
maximize functioning
move child towards independence
improve quality of life
What is the best tested method of autism treatment?
Applied behavioral analysis
Which pervasive developmental disorder is described below?
Will have normal language and cognitive development (good talking ability)
Mild social problems
Poor eye contact
Can be functional in society
Still can be rigid in structure – don’t like deviation from structure
Asperger’s Syndrome
Which pervasive developmental disorder is described below?
Almost exclusively in girls
Genetic mutation of MECP2 on X Chromosome with initial normal
development
Rhett’s Syndrome
Rhett’s Syndrome has what genetic mutation?
Genetic mutation of MECP2 on X Chromosome
Which pervasive developmental disorder is described below?
Normal development for the first two years of life, then loss of
previously acquired skills in language, social skills, bowel or bladder
control, play, or motor skills
Childhood Disintegrative Disorder
