    Study Notes

    Neurodevelopmental Disorders

    • Formerly known as "Disorders usually first diagnosed in childhood or adolescence," this classification of disorders emphasizes that their manifestations typically appear during the early developmental stages of life. This early identification is crucial for effective intervention and support.
    • The term "neurodevelopmental" indicates both an early onset of symptoms and suggests a neurobiological basis for these conditions. This underscores the importance of understanding how early brain development is related to later psychological and behavioral outcomes.
    • Neurodevelopmental disorders often involve adverse events that take place during gestation or around the time of birth, suggesting that factors such as maternal health, environmental exposures, and genetic predispositions can have lasting effects on a child's development.
    • The childhood years are considered particularly critical because significant brain development continues for several years after birth. The brain undergoes rapid growth and forms essential neural connections that support various functions such as language, emotion regulation, and social interactions.
    • Critical developments occur in social, emotional, cognitive, and other important competency areas during childhood, which are foundational for later learning and behavior. These competencies are interrelated; therefore, an impairment in one area can impact others.
    • These developmental changes follow a specific pattern: the child typically develops one skill or ability before acquiring the next. Early competencies lay the groundwork for more complex skills; for example, language development is closely tied to social interactions, which can lead to both verbal and non-verbal communication skills.
    • Some researchers believe that individuals diagnosed with autism spectrum disorder (ASD) experience a significant disruption in early social development, impacting their ability to form connections and communicate with others.
    • The absence of early and meaningful social relationships can have serious consequences for development. Children without adequate social interaction often face challenges in developing the skills needed for effective communication, leading to potential issues in education, social functioning, and personal relationships.
    • Children whose motivation to engage with others is disrupted may encounter a more difficult path in learning how to communicate appropriately, which can complicate their educational experiences and social integration.

    Intellectual Disability (Intellectual Developmental Disorder)

    • Intellectual disability (ID) has undergone dramatic and fundamental changes in its conceptualization and classification over the past few decades, reflecting advances in understanding developmental psychology and neuroscience.
    • ID manifests in a variety of ways across individuals; while some may function well enough to live independently, others may require considerable support in daily living tasks, highlighting the diverse spectrum of cognitive abilities and adaptive functioning among those diagnosed with this disorder.
    • The disorder is marked by significantly below-average intellectual functioning, typically assessed through standardized intelligence tests, alongside adaptive functioning deficits that impact everyday life activities.
    • Individuals experiencing ID struggle with daily activities, which reflect the severity of their cognitive deficits and the level of support they receive from caregivers, educational providers, and support systems within their communities.
    • The DSM-5 outlines difficulties in three primary domains associated with intellectual disability: conceptual (academic learning), social (interpersonal skills), and practical (personal independence). These domains help specify the areas in which individuals may require assistance or intervention.

    General Criteria of Intellectual Disability (Intellectual Developmental Disorder)

    • Deficits in intellectual functions include a range of cognitive abilities, particularly in reasoning, problem-solving, planning, abstract thinking, judgment, academic learning, and experiential learning.
    • Deficits in adaptive functioning may impact social participation, independent living skills, and overall daily functioning, requiring ongoing support from others in various life domains.
    • The diagnosis must demonstrate an onset during the developmental period, which typically spans from the prenatal phase through to the age of 18.
    • When diagnosing intellectual disability, it is crucial to specify if the condition is Mild, Moderate, Severe, or Profound, as this classification helps tailor support and intervention approaches according to individual needs.

    Global Developmental Delay

    • Global developmental delay is a diagnosis that is specifically reserved for individuals younger than 5 years of age, where the clinical severity level cannot be reliably assessed during early childhood. This designation provides flexibility in addressing developmental needs that may not yet be fully articulated.
    • This diagnosis is made when an individual fails to meet expected developmental milestones across multiple areas of intellectual functioning, which can present as delays in motor, communicative, or cognitive skills.
    • Individuals diagnosed with global developmental delay are considered unable to undergo systematic assessments of intellectual functioning. Therefore, the focus is often on early interventions and support rather than labeling deficits, acknowledging that many young children may catch up developmentally as they grow.
    • Reassessment of developmental progress is required after a designated period, ensuring ongoing monitoring and support as children grow and develop their skills.

    Specific Learning Disorder

    • Specific learning disorder is characterized by persistent difficulties in learning and utilizing academic skills, which typically has an onset during the developmental period, often evident when students engage in formal education.

    General Criteria of Specific Learning Disorder

    • Individuals must face challenges in learning and using academic skills for at least 6 months, despite receiving appropriate interventions aimed at helping them improve their performance.
    • The affected academic skills are quantifiably low when compared to their peers of the same age, making it clear that these difficulties are not merely examples of varying ability but rather indicative of a deeper learning issue.
    • This disorder typically manifests during school-age years; earlier signs may often go unnoticed until the demands of academic tasks increase.
    • Importantly, the learning problem should not be explained more effectively by other disabilities, such as intellectual disability or sensory impairments, nor should a lack of appropriate educational instruction be responsible for the observed academic difficulties.

    Specific Learning Disorders

    • When identifying specific learning disorders, further specification is needed to categorize the particular type of learning difficulty: Dyslexia (reading difficulties), Dysgraphia (writing difficulties), or Dyscalculia (mathematical difficulties). This specificity aids in tailoring educational strategies and interventions accordingly.

    Communication Disorders

    • Communication disorders comprise a group of disorders characterized by difficulties in the areas of speech and language, which can significantly affect an individual’s ability to interact effectively with others.

    Language Disorder

    • A language disorder entails a persistent disturbance in the acquisition and use of spoken language, written language, or sign language that arises from deficits in comprehension or production.

    General Criteria of Language Disorder

    • Individuals experience persistent difficulties in acquiring and utilizing language across various modalities (such as written and spoken), which indicates a fundamental impairment rather than simple inconvenience.
    • The language abilities assessed are quantifiably low compared to peers of the same age, establishing that performance falls below what is expected.
    • Manifestations of this disorder occur during the neurodevelopmental period, typically before adolescence.
    • This impairment in language is not attributable to factors such as hearing impairment, other sensory problems, motor difficulties, or any other medical conditions that could impede language learning.

    Speech Sound Disorder

    • Speech sound disorder is characterized by persistent difficulties in speech production that are considered developmentally inappropriate. These difficulties can impact aspects of articulation, fluency, and voice production.
    • This condition often coexists with other challenges such as language disorders, intellectual disabilities, and various neurological conditions, suggesting a complex interplay between different areas of development.

    General Criteria of Speech Sound Disorder

    • Individuals present with persistent difficulties in producing speech sounds that prevent effective verbal communication of messages, leading to frustration in both the speaker and the listener.
    • This disturbance in speech sound production can interfere with the individual’s social participation, academic achievement, and overall quality of life.
    • Manifestation of the disorder typically occurs during the early developmental period when language acquisition is critical.
    • The difficulties experienced are not attributable to congenital conditions or other medical conditions, emphasizing the need for targeted therapeutic interventions.

    Childhood-Onset Fluency Disorder (Stuttering)

    • Childhood-onset fluency disorder, commonly known as stuttering, refers to a disturbance in the normal fluency and time patterning of speech that is deemed inappropriate for the individual's age, making communication challenging.
    • This disorder can manifest in several ways, including frequent repetitions of words or phrases, prolongation of certain sounds, silent blocking where the individual is unable to produce sound at all, or pauses that disrupt the flow of speech.

    General Criteria of Childhood-Onset Fluency Disorder (Stuttering)

    • Individuals exhibit a disturbance in the normal fluency and time patterning of their speech, leading to noticeable irregularities during verbal communication.
    • This speech disturbance frequently provokes anxiety about speaking or effective communication, which can exacerbate the problem and affect social interactions.
    • The disorder typically manifests during the early developmental period; however, in some cases, a late onset is possible, highlighting the varied presentations of the disorder.
    • Importantly, the symptoms are not attributable to a speech-motor or sensory deficit, nor are they caused by other underlying medical conditions that could induce similar speech difficulties.

    Social (Pragmatic) Communication Disorder

    • Social (pragmatic) communication disorder is marked by difficulties in the pragmatic aspects of social communication, which includes challenges in comprehension, formulation, and discourse comprehension, leading to misunderstandings in social situations.
    • Individuals may encounter common difficulties in social communication, further complicating their interactions within peer groups and other social contexts.

    General Criteria of Social (Pragmatic) Communication Disorder

    • Persistent difficulties are evident in the social use of verbal and nonverbal communication; this includes basic skills such as greeting others, taking turns during conversations, and adhering to the implicit rules governing interactions.
    • This deficit in social communication often results in functional limitations that inhibit effective communication in various contexts, such as school, work, and personal relationships.
    • The onset of social (pragmatic) communication disorder occurs during the developmental period, indicating that early intervention may be beneficial for improving outcomes.
    • Importantly, this disorder is not attributed to other medical conditions, reinforcing the need for specific therapeutic strategies targeting the unique challenges individuals face.

    Motor Disorders

    • Motor disorders encompass a range of conditions that affect physical movement and coordination, reflecting underlying neurological or developmental issues.
    • Stereotypic movement disorder and Tourette’s disorder are two primary examples of motor disorders that can significantly impact daily functioning and social interactions.

    Stereotypic Movement Disorder

    • Stereotypic movement disorder is characterized by repetitive, seemingly driven, and purposeless motor behaviors that can be distracting or disruptive.
    • Typical movements associated with this disorder may include behaviors such as hand waving, rocking, playing with hands, head banging, self-biting, and hitting various parts of one’s own body, often serving as a means of self-soothing or coping.

    General Criteria of Stereotypic Movement Disorder

    • Individuals exhibit repetitive movements that are driven by an urge and appear purposeless, which may lead to social stigma or exclusion due to misunderstanding of the behavior.
    • These repetitive movements can interfere with social interactions, academic achievements, and participation in everyday activities, sometimes resulting in self-injurious behavior.
    • Onset typically occurs during the early developmental period, thereby influencing early childhood experiences significantly.
    • Repetitive movements are not attributed to any neurological disorder or other medical conditions, highlighting the uniqueness of the diagnosis.

    Stereotypic Movement Disorder

    • It is crucial to specify whether the disorder presents with or without self-injurious behavior, whether it is associated with a known medical or genetic condition, and to indicate the severity of symptoms for effective intervention planning.

    Tourette’s Disorder

    • Tourette’s disorder, also referred to as Gilles de la Tourette’s syndrome, is characterized by the presence of multiple stereotypical but nonrhythmic motor movements and vocalizations, which can vary widely among individuals.
    • Vocal tics may take on socially offensive or disruptive forms; examples include shouting inappropriate words, barking, or making other sudden noises, which can often lead to embarrassment or social isolation for those affected.
    • The individual is generally aware of their tics and may exert limited control over them, but they ultimately find themselves compelled to submit to the urges to engage in these movements or vocalizations.

    General Criteria of Tourette’s Disorder

    • Multiple motor and vocal tics must have been present during the period of illness; however, these tics do not necessarily need to occur simultaneously.
    • While the frequency of the tics may increase or decrease, they typically persist for more than 1 year, indicating a chronic nature.
    • Onset of tics generally occurs before the age of 18, drawing attention to the importance of early identification and intervention.
    • The presence of tics is not attributed to other medical conditions or physiological substances, reinforcing the specificity of the diagnosis.

    Autism Spectrum Disorder

    • Autism spectrum disorder (ASD) is an umbrella term encompassing a range of conditions, including autism, Asperger syndrome, and pervasive developmental disorders, illustrating the variability in symptoms and severity within this category.
    • This disorder was first described by Leo Kanner, who identified it as a syndrome characterized by deficits in social communication combined with repetitive and stereotyped behaviors appearing in early childhood.
    • The diagnosis has been reconceptualized as a "spectrum," which acknowledges the range of symptoms and manifestations that were previously classified as distinct conditions in earlier versions of the DSM, enhancing the understanding of developmental differences.

    Autism Spectrum Disorder

    • Individuals with ASD experience persistent deficits in reciprocal social communication, which encompasses challenges in nonverbal communicative behaviors that are typically used for social interaction, as well as in the areas of developing, managing, and understanding relationships with others.

    General Criteria of Autism Spectrum Disorder

    • Deficits in social communication and interaction are evident across multiple contexts, suggesting that the challenges faced are not situational but rather fundamental to the individual.
    • Individuals with ASD may display restricted and repetitive patterns of behavior, interests, or activities, which can include repetitive movements, strict adherence to routines, or intensely focused interests.
    • Symptoms generally onset during the developmental period, indicating that early recognition and intervention are vital for improving outcomes.
    • These symptoms often result in significant impairment in several areas of life, including education, social relationships, and occupational functioning.
    • The symptoms must not be attributed to other medical disorders, ensuring that ASD is diagnosed distinctly based on its unique characteristics.

    Autism Spectrum Disorder

    • Individuals who previously received a well-established DSM-IV diagnosis of autistic disorder, Asperger’s disorder, or pervasive developmental disorder not otherwise specified should now receive the diagnosis of autism spectrum disorder, reflecting the updated understanding of these conditions.

    Autism Spectrum Disorder

    • Different aspects must be specified, which may include the presence or absence of accompanying intellectual impairment, with or without accompanying language impairment, any associations with known medical, genetic, or environmental factors, connections to other neurodevelopmental, mental, or behavioral disorders, and whether the individual exhibits symptoms of catatonia, to provide a thorough understanding of the disorder in an individual context.

    Attention-Deficit/Hyperactivity Disorder

    • Attention-deficit/hyperactivity disorder (ADHD) was first acknowledged in the DSM-II under the descriptor "hyperkinetic reaction of childhood," noting the historical context of its understanding as a childhood condition associated with visible hyperactivity.
    • ADHD is characterized by a range of symptoms, including overactivity, restlessness, distractibility, and a markedly short attention span, making it difficult for affected individuals to focus on everyday tasks.

    Attention-Deficit/Hyperactivity Disorder

    • Criteria for diagnosing ADHD have been revised in DSM-IV, shifting the focus onto two broad symptom groups: those indicating difficulty in focusing and maintaining attention, and those reflecting hyperactivity and impulsivity.

    Attention-Deficit/Hyperactivity Disorder

    • Several changes have been made to this diagnosis in the DSM-5; notably, the age of onset has shifted from 7 years to 12 years old, reflecting a better understanding of developmental trajectories and the varying presentations of symptoms over time.
