Child and Adolescent Psychiatry Practice Questions

Q: Severe mental retardation is:

20-35. ***20-35*** - A **score between 20-35** indicates **severe mental retardation**, where individuals typically have very limited communication skills and require extensive support in daily living activities. - This range is associated with significant cognitive impairment that often necessitates full-time supervision. *<20* - An **IQ score below 20** signifies **profound mental retardation**, indicating extremely limited intellectual functioning and severe developmental delays. - Individuals in this category generally have very minimal capacity for self-care or communication. *35-50* - This IQ range reflects **moderate mental retardation**, where individuals can often develop some basic communication and self-care skills, but still require significant support. - They may live semi-independently with supervision, but struggle with academic and complex social tasks. *50-70* - An **IQ score between 50-70** is classified as **mild mental retardation**, which is the most common form. - Individuals often achieve academic skills up to a 6th-grade level and can live independently with appropriate support.

Q: An IQ of 40 corresponds to which level of intellectual disability?

Moderate. ***Moderate*** - An **IQ score between 35 and 49** is classified as moderate intellectual disability. - Individuals with moderate intellectual disability often require **supervision** but can develop some communication and self-care skills. *Mild* - **IQ scores between 50 and 69** are indicative of mild intellectual disability. - Individuals with mild intellectual disability can often achieve academic skills up to a **sixth-grade level** and live independently with support. *Profound* - **IQ scores below 20** signify profound intellectual disability. - Individuals with profound intellectual disability require **intensive support** for all activities of daily living and have minimal communication skills. *Severe* - **IQ scores between 20 and 34** fall into the severe intellectual disability category. - Individuals with severe intellectual disability have significant **impairments in adaptive functioning** and require substantial support for self-care and communication.

Q: A 15-year-old adolescent is brought in for evaluation due to repeated failure to conform to social norms, deceitfulness, impulsivity, and lack of remorse. What is the most likely diagnosis?

Conduct disorder. ***Conduct disorder*** - This diagnosis is characterized by repeated patterns of behavior that **violate the rights of others** or major societal norms, consistent with the patient's presentation of **deceitfulness, impulsivity, and lack of remorse**. - For individuals under 18, it is the appropriate diagnosis, as **Antisocial Personality Disorder** cannot be diagnosed before turning 18. *Oppositional defiant disorder* - This condition involves a pattern of **angry/irritable mood, argumentative/defiant behavior**, or vindictiveness. It does not typically include the severe violations of societal norms or the rights of others seen in this case. - While there is defiance, it generally lacks the **aggression** towards people/animals, **destruction of property**, or **deceitfulness/theft** that characterize conduct disorder. *Intermittent explosive disorder* - This disorder is marked by **recurrent behavioral outbursts** representing a failure to control aggressive impulses. - The outbursts are typically **disproportionate** to the provocation but do not necessarily involve the persistent pattern of violating others' rights or societal rules as described. *Antisocial personality disorder* - This diagnosis requires an individual to be at least **18 years old** and have a history of conduct disorder symptoms before age 15. - Although the symptoms align with the criteria for **antisocial behavior**, the patient's age (15 years old) precludes this diagnosis.

Q: A 10-year-old boy exhibits significant difficulty in maintaining attention, excessive activity, and impulsivity. The most likely diagnosis is:

Attention-Deficit/Hyperactivity Disorder. ***Attention-Deficit/Hyperactivity Disorder (ADHD)*** - This presentation of **significant difficulty in maintaining attention**, **excessive activity**, and **impulsivity** represents the **three core diagnostic features of ADHD** according to DSM-5 criteria. - ADHD requires symptoms to be present in **at least two settings** (e.g., home and school) and cause **significant impairment** in social, academic, or occupational functioning. - The age of presentation (10 years) is typical, as symptoms must be present **before age 12** for diagnosis. *Autism Spectrum Disorder (ASD)* - ASD is characterized primarily by deficits in **social communication and social interaction**, along with **restricted, repetitive patterns of behavior, interests, or activities**. - While attention difficulties can co-occur with ASD, they are not the primary defining features. - The stem does not describe social communication deficits or repetitive behaviors that would suggest ASD. *Conduct Disorder* - Involves a **repetitive and persistent pattern** of behavior violating the **basic rights of others** or **major age-appropriate societal norms or rules**. - Key features include aggression toward people or animals, destruction of property, deceitfulness or theft, and serious rule violations. - The stem describes attention and impulse control issues, not antisocial behaviors. *Oppositional Defiant Disorder (ODD)* - Characterized by a pattern of **angry/irritable mood**, **argumentative/defiant behavior**, or **vindictiveness** directed toward authority figures. - While impulsivity may be present, the primary features in the stem (inattention and hyperactivity) point more directly to ADHD rather than oppositional behaviors.

Q: Which condition is characterized by difficulties in reading and spelling due to a phonological processing deficit?

Dyslexia. ***Dyslexia*** - **Dyslexia** is a **specific learning disorder** characterized by significant difficulties in **accurate and/or fluent word recognition** and **poor spelling**. - These difficulties often stem from a deficit in the **phonological component of language**, meaning trouble processing the sounds of language. *Intellectual Disability* - **Intellectual disability** involves significant limitations in **both intellectual functioning** (e.g., reasoning, problem-solving) and **adaptive behavior**. - While individuals with intellectual disability may have reading difficulties, these are part of a **broader cognitive impairment**, not a specific phonological processing deficit in isolation. *Down Syndrome* - **Down syndrome** is a genetic disorder caused by the presence of an extra full or partial copy of **chromosome 21**. - It leads to characteristic **physical features** and **developmental delays**, but reading and spelling difficulties are secondary to overall cognitive development, not a primary phonological processing deficit specific to reading. *Attention Deficit Hyperactivity Disorder (ADHD)* - **ADHD** is a neurodevelopmental disorder characterized by **persistent patterns of inattention** and/or **hyperactivity-impulsivity**. - While ADHD can impact academic performance and may co-occur with dyslexia, its primary features are related to **executive function** and concentration, not difficulties in **decoding** or **phonological processing** specific to reading and spelling.

Q: What is the current preferred term for the condition previously known as mental retardation?

Intellectual disability. ***Correct: Intellectual disability*** - This term was adopted to replace "mental retardation" due to its less stigmatizing nature and its focus on **cognitive and adaptive functioning** - It emphasizes the need for supports and services to help individuals achieve their potential, rather than simply labeling a deficit - Officially adopted in **DSM-5 (2013)** and mandated by **Rosa's Law (2010)** in federal terminology *Incorrect: Feeble Mindedness* - This is an **outdated and derogatory term** that was used historically to describe individuals with cognitive impairments - Its use has been discontinued due to its negative and dehumanizing connotations *Incorrect: Madness* - This term typically refers to severe **mental illness** or **psychosis**, not intellectual impairment - It is an informal and often stigmatizing term that is not used in clinical or diagnostic contexts for intellectual functioning *Incorrect: Mentally unstable* - This term is often used to describe individuals experiencing **fluctuations in mood**, **behavior**, or **thought processes**, usually associated with mental health conditions - It does not specifically refer to global cognitive deficits or intellectual functioning

Q: Which of the following statements is true regarding Asperger syndrome?

Language development is generally normal. ***Language development is generally normal*** - A key distinguishing feature of **Asperger syndrome** (now part of **Autism Spectrum Disorder**) is the **absence of a clinically significant delay in language development**, unlike other forms of autism. - Individuals with Asperger's often have a rich vocabulary and can speak fluently, though their **pragmatic use of language** (social communication) may be impaired. *Repetitive activity pattern* - While **repetitive behaviors** and **restricted interests** are characteristic of Asperger syndrome, this statement is a **feature of, not the defining true statement** that differentiates it from other ASDs or highlights its unique aspects in relation to language. - This symptom is also common in other autism spectrum disorders. *Intellectual disability is commonly present* - Individuals with Asperger syndrome typically have **average or above-average intelligence**, and **intellectual disability is not common**. - This distinguishes it from many other conditions classified under Autism Spectrum Disorder. *Equally common in boys and girls* - Asperger syndrome, like other forms of autism, is **more commonly diagnosed in males than in females**, with estimated ratios varying from 2:1 to 16:1. - This gender disparity suggests a biological component or a difference in presentation leading to underdiagnosis in girls.

Q: Which of the following is not considered a habit disorder?

Temper tantrum. ***Temper tantrum*** - A **temper tantrum** is an emotional outburst, typically in young children, characterized by **stubbornness**, crying, screaming, and physical aggression, and is not classified as a habit disorder. - While it can be a learned behavior, it primarily reflects an inability to regulate emotions and is not a focused, repetitive habit like those seen in habit disorders. *Nail biting* - **Nail biting** (onychophagia) is a repetitive body-focused behavior often triggered by **anxiety** or stress. - It falls under **body-focused repetitive behaviors** (BFRBs), which are considered habit disorders. *Thumb sucking* - **Thumb sucking** is a common habit in infants and young children, often serving as a **self-soothing mechanism**. - If it continues past a certain age or causes dental problems, it is classified as a habit disorder. *Hair pulling (trichotillomania)* - **Trichotillomania** is characterized by the **recurrent urge to pull out one's hair**, leading to noticeable hair loss. - It is classified as an **obsessive-compulsive and related disorder** in DSM-5, which is distinct from simple habit disorders. - While it has repetitive features, it involves complex urges and tension relief patterns beyond typical habit disorders like nail-biting or thumb-sucking.
