Normal vs Abnormal Behavior
Normal vs Abnormal: Depends on age and cultural background
Key: deviation from development and normative standards
Setting: home, school, generalized, etc
Neurodevelopmental disorders
A category of mental disorders in the DSM-5 affecting children and adolescents and that involve impaired brain functioning or development
⅕ American children and young adults develops a psychological disorder
- Fail to get the treatment they need
types of Neurodevelopmental disorders
Autism spectrum disorder
Intellectual disability
Specific learning disorder
Communication disorders
attention-deficit/hyperactivity disorder
Autism spectrum disorder (ASD)
A developmental disorder characterized by significant deficits in communication and social interaction, as well as development of restricted or fixed interests and repetitive behaviors
Chronic, lifelong condition
Prevalence has been rising steadily for several decades
5x as common in boys as girls
DSM
Asperger’s disorder was a distinct diagnosis in the previous edition of the DSM but is not classified in the DSM-5 as a form of autism spectrum disorder
asperger’s
A pattern of behavior characterized by social awkwardness and stereotyped or repetitive behaviors but without the significant language or cognitive deficits associated with more severe forms of autism spectrum disorder
criteria of Autism spectrum disorder (ASD)
A) Persistent deficits in social communication and social interaction across multiple contexts, as manifested by all of the following, currently, or by history
1. Deficits in social-emotional reciprocity, ranging, for example, from abnormal social approach and failure of normal back-and-forth to initiate or respond to social interactions
2. Deficits in nonverbal communicative behaviors used for social interaction, randing, for example, from poorly integrated verbal and nonverbal communication; to abnormalities in eye contact and body language or deficits in understanding and use of gestures; to a total lack of facial expressions and nonverbal communication
3. Deficits in developing, maintaining, and understanding relationships, ranging, for example, from difficulties adjusting behavior to suit various social contexts; to difficulties in sharing imaginative play or in making friends; to absence of interest in peers
B) Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following, currently, or by history
1. Stereotyped or repetitive motor movements, use of objects, or speech (e.g., simple motor stereotypies, lining up toys or flipping objects, echolalia, idiosyncratic phrases).
2. Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behavior (e.g., extreme distress at small changes, difficulties with transitions, rigid thinking patterns, greeting rituals, need to take same route or eat
same food every day).
3. Highly restricted, fixated interests that are abnormal in intensity or focus (e.g., strong attachment to or preoccupation with unusual objects, excessively circumscribed or
perseverative interests).
4. Hyper- or hypo reactivity to sensory input or unusual interest in sensory aspects of the environment (e.g., apparent indifference to pain/temperature, adverse response to specific sounds or textures, excessive smelling or touching of objects, visual fascination with lights or movement).
C) Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies in later life).
D) Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.
E) These disturbances are not better explained by intellectual developmental disorder (intellectual disability) or global developmental delay. Intellectual developmental disorder and autism spectrum disorder frequently co-occur; to make comorbid diagnoses of autism spectrum disorder and intellectual developmental disorder, social communication should be below that expected for general developmental level.
Severity levels of ASD
Level 1 - Requiring Support
Level 2 - Requiring Substantial Support
Level 3 - Requiring Very Substantial Support
specify if ASD
With or without accompanying intellectual impairment
With or without accompanying language impairment
Associated with a known genetic or other medical condition or environmental factor
Associated with a neurodevelopmental, mental, or behavioral problem With catatonia
features of ASD
Most poignant feature: aloneness
mute
echolalia (parroting back what the child has heard in a high pitched monotone)
Nonverbal communication may also be impaired or absent
Interminably twirling, flapping the hands, rocking back and forth with the arms around the knees
Preservation of sameness
Lack a differentiated self-concept and sense of themselves
Theoretical Perspectives on Autism
early
cognitive theory
genetic factors
brain abnormalities
environmental influences?
Early and now discredited belief of ASD
Reaction to parents who were cold and detached – “emotional refrigerators”
ASD cognitive theory
limited ability to process multiple stimuli at one time, aka slow stimuli association
- Difficulty integrating information from various senses
- Over or under sensitivity to stimulation, diminishing capacity to ‘make use’ of information
ASD genetic factors
high twin concordance
ASD brain abnormalities
abnormalities in neuron connection and loss of brain tissue
Autism Spectrum Disorder - Treatment
Treatment depends on ‘severity’
Behavioral treatment
- Applied behavior analysis
- Operant conditioning to increase ability to attend to others, play with others, develop academic skills and keep from self mutilation
- Intensive, 1:1
- Imitation skills
- Apps
Intellectual Disability (ID)
A generalized delay or impairment in the development of intellectual and adaptive abilities
Begins before the age of 18; improves over time (especially if they receive support, guidance, and enriched educational opportunities)
Affects conceptual, socialism and practical skills
DSM earlier - <70 IQ → DSM now doesn’t set any specific score
Causes
- Chromosomal and genetic disorders, infectious diseases, maternal alcohol use during pregnancy
- Exposure to an impoverished home environment
criteria of ID
A) Intellectual developmental disorder (intellectual disability) is a disorder with onset during the developmental period that includes both intellectual and adaptive functioning deficits in conceptual, social, and practical domains. The following three criteria must be met:
1. Deficits in intellectual functions, such as reasoning, problem solving, planning, abstract thinking, judgment, academic learning, and learning from experience, confirmed by both clinical assessment and individualized, standardized intelligence testing.
2. Deficits in adaptive functioning that result in failure to meet developmental and sociocultural standards for personal independence and social responsibility. Without ongoing support, the adaptive deficits limit functioning in one or more activities of daily life, such as communication, social participation, and independent living, across multiple environments, such as home, school, work, and community.
3. Onset of intellectual and adaptive deficits during the developmental period.
Intellectual Disability - Causes
chromosomal abnormalities
genetic disorders
prenatal factors
ID - chromosomal abnormalities
Down syndrome - extra chromosome (47)
- A condition caused by the presence of an extra chromosome on the 21st pair and characterized by intellectual developmental disorder and various physical abnormalities
- 1/800 births
- Physical features: a round face, broad/flat nose, small/downward-sloping folds of skin at the inside corners of the eyes, protruding tongue, small hands, short fingers, disproportionately small arms and legs in relation to their bodies
Klinefelter - presence of an extra X chromosome
Turner syndrome - Single X instead of two X chromosomes
ID - genetic disorders
Fragile X Syndrome
- An inherited form of intellectual developmental disorder caused by a mutated gene on the X chromosome
- 1.4/10,000 males and 0.9/10,000 females
- Effects: range from mild learning disorders to ID so profound that those affected can hardly speak or function
Phenylketonuria (PKU)
- A genetic disorder that prevents the metabolization of phenylpyruvic acid, leading to intellectual development disorder unless the diet is strictly controlled
- Caused by a recessive gene
- damaging CNS
ID - prenatal factors
Maternal disease - Rubella (German measles) passed along from mother to child
Drugs
Maternal alcohol use - Ex: fetal alcohol syndrome
Intellectual Disability - Interventions
Aimed at level of severity and geared to increase function
Psycho Education and skills work to assist in vocational skills and professional work
institution, home care and residential options for the most severe cases
Psychotherapy supporting their experiences as other
Dyslexia
A learning disorder characterized by an impaired ability to read
Most common of all - 80%
Learning disorder
A deficiency in a specific learning ability in the context of normal intelligence and exposure to learning opportunities
Chronic
Children - perform poorly in school
DSM-5
Applies a single diagnosis of specific learning disorder to encompass various types of learning disorders or disabilities involving significant deficits in skills involved in reading, writing, arithmetic, and math
