DSM-5 EXAM: Neurodevelopmental Disorders

Which of the following statements about global developmental delay is true? A. The diagnosis is typically made in children younger than 5 years of age. B. The etiology can usually be determined. C. The prevalence is estimated to be between 0.5% and 2%. D. The condition is progressive. E. The condition does not generally occur with other neurodevelopmental disorders.

Answer: A. The diagnosis is typically made in children younger than 5 years of age. (Page 41).

Which of the following statements about intellectual disability (intellectual developmental disorder) is false? A. Individuals with intellectual disability have deficits in general mental abilities and impairment in everyday adaptive functioning compared with age and gender-matched peers from the same linguistic and sociocultural group. B. For individuals with intellectual disability, the full-scale IQ score is a valid assessment of overall mental abilities and adaptive functioning, even if subtest scores are highly discrepant. C. Individuals with intellectual disability may have difficulty in managing their behavior, emotions, and interpersonal relationships and in maintaining motivation in the learning process. D. Intellectual disability is generally associated with an IQ that is 2 standard deviations from the population E. Assessment procedures for intellectual disability must take into account factors that may limit performance, such as sociocultural background, native language, associated communication/language disorder, and motor or sensory handicap.

Answer: B. For individuals with intellectual disability, the full-scale IQ score is a valid assessment of overall mental abilities and adaptive functioning, even if subtest scores are highly discrepant. (Page 37).

A 7-year-old boy in second grade displays significant delays in his ability to reason, solve problems, and learn from his experiences. He has been slow to develop reading, writing, and mathematics skills in school. All through development, these skills lagged behind peers, although he is making slow progress. These deficits significantly impair his ability to play in an age-appropriate manner with peers and to begin to acquire independent skills at home. He requires ongoing assistance with basic skills (dressing, feeding, and bathing himself; doing any type of schoolwork) on a daily basis. What is the appropriate severity rating for this patient's current presentation? A. Mild. B. Moderate. C. Severe. D. Profound. E. Cannot be determined without an IQ score.

Answer: B. Moderate (Page 37).

Which of the following statements about the development and course of autism spectrum disorder (ASD) is false? A. Symptoms of ASD are typically recognized during the second year of life (12-24 months of age). B. Symptoms of ASD are usually not noticeable until 5-6 years of age or later. C. First symptoms frequently involve delayed language development, often accompanied by lack of social interest or unusual social interactions. D. ASD is not a degenerative disorder, and it is typical for learning and compensation to continue throughout life. E. Because many normally developing young children have strong preferences and enjoy repetition, distinguishing restricted and repetitive behaviors that are diagnostic of ASD can be difficult in preschoolers.

Answer: B. Symptoms are not typically noticeable until 5-6 years of age or later. (Page 55-56).

In which of the following situations would a diagnosis of global developmental delay be inappropriate? A. The patient is a child who is too young to fully manifest specific symptomsor to complete requisite assessments. B. The patient, a 7-year-old boy, has a full-scale IQ of 65 and severe impairment in adaptive functioning. C. The patient's scores on psychometric tests suggest intellectual disability (intellectual developmental disorder), but there is insufficient information about the patient's adaptive functional skills. D. The patient's impaired adaptive functioning suggests intellectual developmental disorder, but there is insufficient information about the level of cognitive impairment measured by standardized instruments. E. The patient's cognitive and adaptive impairments suggest intellectual developmental disorder, but there is insufficient information about age at onset of the condition.

Answer: B. The patient, a 7-year-old boy, has a full-scale IQ of 65 and severe impairment in adaptive functioning. 1.12—Global Developmental Delay (p. 41)

Which of the following statements about development of and risk factors for intellectual disability (intellectual developmental disorder) is true? A. Intellectual developmental disorder should not be diagnosed in the presence of a known genetic syndrome, such as Lesch-Nyhan or Prader-Willi syndrome. B. Etiologies are confined to perinatal and postnatal factors and exclude prenatal events. C. In severe acquired forms of intellectual developmental disorder, onset maybe abrupt following an illness (e.g., meningitis) or head trauma occurring during the developmental period. D. When intellectual disability results from a loss of previously acquired cognitive skills, as in severe traumatic brain injury (TBI), only the TBI diagnosis is assigned. E. Prenatal, perinatal, and postnatal etiologies of intellectual developmental disorder are demonstrable in approximately 33% of cases.

Answer: C. In severe acquired forms of intellectual developmental disorder, onset may be abrupt following an illness (e.g., meningitis) or head trauma occurring during the developmental period. (Page 38-39).

Which of the following statements about adaptive functioning in the diagnosis of intellectual disability (intellectual developmental disorder) is true? A. Adaptive functioning is based on an individual's IQ score. B. "Deficits in adaptive functioning" refers to problems with motor coordination. C. At least two domains of adaptive functioning must be impaired to meet Criterion B for the diagnosis of intellectual disability. D. Adaptive functioning in intellectual disability tends to improve over time, although the threshold of cognitive capacities and associated developmental disorders can limit it. E. Individuals diagnosed with intellectual disability in childhood will typically continue to meet criteria in adulthood even if their adaptive functioning improves.

Answer: D. Adaptive functioning tends to improve over time, although the threshold of cognitive capacities and associated developmental disorders can limit it. 1.7—Intellectual Disability (Intellectual Developmental Disorder) / Specifiers (pp. 33-36); Diagnostic Features (pp. 37-38); Development and Course (pp. 38-39)

A 10-year-old boy with a history of dyslexia, who is otherwise developmentally normal, is in a skateboarding accident in which he experiences severe traumatic brain injury. This results in significant global intellectual impairment (with a persistent reading deficit that is more pronounced than his other newly acquired but stable deficits, along with a full-scale IQ of 75).

He is also displaying anxious and depressive symptoms in response to his accident and hospitalization. What is the least likely diagnosis? A. Intellectual disability (intellectual developmental disorder). B. Traumatic brain injury. C. Specific learning disorder. D. Major neurocognitive disorder due to traumatic brain injury. E. Adjustment disorder.

Answer: D. Major neurocognitive disorder due to traumatic brain injury. (Page 40).

An individual with an IQ above 75 would not meet diagnostic criteria even if there were impairments in adaptive functioning. C. In forensic assessment, severe deficits in adaptive functioning might allow for a diagnosis with an IQ above 75. D. Adaptive functioning must take into account the three domains of conceptual, social, and practical functioning. E. The specifiers mild, moderate, severe, and profound are based on IQ scores.

Answer: E. The specifiers mild, moderate, severe, and profound are based on IQ scores. (Page 33).

Although he does not currently note motor restlessness like his son, he recalls being that way when he was a boy, along with being quite inattentive, being impulsive, talking excessively, interrupting, and having problems waiting his turn. He was an underachiever in high school and college, when he inconsistently did his work and had difficulty following rules. Nevertheless, he never failed any classes, and he was never evaluated by a psychologist or psychiatrist. He works about 60-80 hours a week and often gets insufficient sleep. He tends to make impulsive business decisions, can be impatient and short-tempered, and notes that his mind tends to wander both in one-on-one interactions with associates and his wife and during business meetings, for which he is often late; he is forgetful and disorganized. Nevertheless, he tends to perform fairly well and is quite successful, although he can occasionally feel overwhelmed and demoralized. What is the most likely diagnosis? A. Major depressive disorder. B. Generalized anxiety disorder. C. Specific learning disorder. D. ADHD, in partial remission. E. Oppositional defiant disorder.

Correct Answer: D. ADHD, in partial remission. (Page 63).

A 15-year-old boy has developed concentration problems in school that have been associated with a significant decline in grades.

A 7-year-old boy is having behavioral and social difficulties in his second grade class. Although he seems to be able to attend and is doing "well" from an academic standpoint (though seemingly not what he is capable of), he is constantly interrupting, fidgeting, talking excessively, and getting out of his seat. He has friends, but he sometimes annoys his peers because of his difficulty sharing and taking turns and the fact that he is constantly talking over them. Although he seeks out play dates, his friends tire of him because he wants to play sports nonstop. At home, he can barely stay in his seat for a meal and is unable to play quietly. Although he shows remorse when the consequences of his behavior are pointed out to him, he can become angry in response and seems nevertheless unable to inhibit himself. What is the most likely diagnosis? A. Bipolar disorder. B. Autism spectrum disorder. C. Generalized anxiety disorder. D. Attention-deficit/hyperactivity disorder, predominantly hyperactive/impulsive.
