    Study Notes

    Developmental Disabilities

    • The term "developmental disabilities" (DD) is used in Ontario to describe certain conditions, but it is important to use it cautiously to avoid stigmatizing or marginalizing individuals.
    • There are many terms that have been used in the past to describe DD, some more appropriate than others.
    • DD can be caused by one or more health conditions, including syndromes and contributing factors.
    • DD affects 2-3% of people worldwide, with 2/3rds experiencing mild to moderate cases and 1/3 experiencing severe to profound cases.
    • The most common DD's in Canada are Autism, Fetal Alcohol Syndrome, Down Syndrome, Fragile X Syndrome, and 22q11 Deletion Syndrome.
    • Approximately 25-50% of all developmental disabilities are caused by biomedical factors, most commonly genetic abnormalities.

    Meaning of Developmental Disability

    • Personal meaning: Focuses on an individual's unique strengths and needs.
    • Literal meaning: Refers to the specific characteristics used to define the disability.
    • Social meaning: Reflects society's tolerance, acceptance, and understanding of the disability, contributing to the broader social perception.
    • Critical disability meaning: Highlights the limitations and shortcomings of the individual.
    • Definitional meaning: Uses a very specific set of criteria to define the presence or absence of a DD.

    AAIDD Defintion of Intellectual Disability

    • Intellectual disability is characterized by significant limitations in both intellectual functioning and adaptive behavior, evident in conceptual, social, and practical skills.
    • The disability must originate before the age of 18.
    • Limitations in functioning should be assessed within the context of the individual's community, age, peers, and culture.
    • Assessment should consider cultural and linguistic diversity and differences in communication, sensory, motor, and behavioral factors.
    • Individuals with DD often possess strengths alongside their limitations.
    • The purpose of describing limitations is to identify the necessary support needed for individuals with DD.
    • With personalized support over time, individuals generally show improvement in their life functioning.

    Diagnosing Developmental Disability

    • Several diagnostic tools are used to assess DD, including:
      • DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition)
      • ICD-11 (International Classification of Diseases, 11th Revision)
      • The Education Act (Ontario)
      • ICF-CY (International Classification of Functioning, Children & Youth)
      • ABAS-3 (Adaptive Behaviour Assessment System Third Edition)
      • Vineland-3 (Adaptive behaviour assessment)

    DSM-5 Classification of Intellectual Disability

    • DSM-5 defines intellectual disability as a disorder present during the developmental period marked by deficits in intellectual and adaptive functioning.
    • Three criteria must be met:
      • Deficits in intellectual functions, confirmed by clinical assessment and standardized intelligence testing.
      • Deficits in adaptive functioning, resulting in problems meeting personal independence and social responsibility standards.
      • Onset of intellectual and adaptive deficits during the developmental period.

    Specifiers for Intellectual Disability in DSM-5

    • Specifiers, such as age of onset, severity ratings, medical conditions, genetic conditions, or environmental factors, provide a detailed clinical description.
    • Severity levels include Mild, Moderate, Severe, and Profound.

    Education Act (Ontario) and Exceptionalities

    • The Education Act (Ontario) designates students as "exceptional" within five categories: Behaviour, Communication, Intellectual, Physical, and Multiple.
    • These designations are legal definitions and may not be equivalent to clinical diagnoses.
    • The Identification, Placement and Review Committee (IPRC) process, governed by Regulation 181/98, determines whether a student is exceptional.

    Severity Levels of Intellectual Disability

    • Mild (85%): Typically not identified until early elementary years, may overrepresent minority groups, develop social and communication skills, and live successfully in the community with support.
    • Moderate (10%): Often identified during preschool years, many individuals with Down syndrome fall into this category, benefit from vocational training, and can perform supervised work in adulthood.
    • Severe (3-4%): Often associated with organic causes, identified at a young age, delays in development and visible physical features are present, require special assistance throughout their lives, and often live in group homes or with their families.
    • Profound (1-2%): Identified in infancy due to significant developmental delays and biological anomalies, learn only basic communication skills, require intensive training, and need lifelong care and assistance.

    Understanding Developmental Disabilities

    • Evolving Perspectives: Previously, developmental disabilities were categorized based on intellectual abilities, communication, and behavior. Now, there's a shift towards a more nuanced understanding.
    • Three Perspectives:
      • Legal Status: Individuals with disabilities often had to relinquish certain rights and privileges to access services, resulting in a different legal status.
      • Biomedical: Focuses on providing institutional care, following strict rules and regulations. Often deficit-driven.
      • Social and Human Rights Model: Examines the impact of social structures on individuals with disabilities, advocating for equality.

    Developmental Disabilities in Ontario

    • Legislative Changes: The Services and Supports to Promote the Social Inclusion of Persons with Developmental Disabilities Act, 2008 replaced the Developmental Services Act.
    • New Definition: Emphasizes functional limitations in cognitive and adaptive functioning beyond IQ. Focuses on life-long impact and affecting areas of major life activity.
    • Person-Centered Approach:
      • Encourages personalized planning with individuals expressing their specific needs and goals.
      • Aim is to promote independence and participation in community activities.
    • Direct Funding: Allows individuals and families more choice and flexibility in accessing services.

    Disability Rights in Canada

    • Canadian Charter of Rights and Freedoms: Safeguards equality for all Canadians, regardless of disability, race, religion, sex, or age.
    • Canadian Human Rights Act (1977): Protects against discrimination based on disability in employment and services provided by the federal government, First Nations governments, and certain private businesses.

    Comorbidity: Mental Health and Developmental Disabilities

    • Dual Diagnosis: Refers to the presence of both a developmental disability and a mental health disorder.
    • Common Mental Health Disorders: Individuals with developmental disabilities experience a similar range of mental disorders as the general population, including mood disorders, anxiety, adjustment problems, personality disorders, and ADHD.
    • Behavioral Challenges: Individuals with co-occurring conditions often exhibit behavioral challenges like aggression, self-harm, attention difficulties, and oppositional behaviors.
    • Higher Prevalence of Autism: Individuals with developmental disabilities are more likely to have Autism Spectrum Disorder.
    • Dual Diagnosis Consultation, Outreach Stabilization Service: This service in Windsor-Essex provides short-term stabilization for individuals 16+ with developmental disabilities and mental health disorders.

    Factors Contributing to Mental Health Concerns

    • Biological Factors: Brain injury, trauma, disease, or infection.
    • Environmental and Psychosocial Factors: Poverty, isolation, lack of employment, limited social opportunities, weak social support, inadequate coping skills, and feelings of inadequacy.

    Epidemiological Considerations

    • Prevalence Rate: Research shows a higher risk of mental illness in the developmental disabilities population. Estimates suggest between 10% and 40% of adults with developmental disabilities experience mental health concerns.

    Clinical Challenges

    • Diagnostic Overshadowing: Tendency to under-recognize emotional or psychiatric disturbances in individuals with developmental disabilities.
    • Behavioral Highlighting: Severe behavior may overshadow underlying mental health concerns.
    • Communication Difficulties: Individuals with significant communication and cognitive impairments may struggle to express their distress.

    Co-morbidity Beyond Mental Illness

    • Individuals with developmental disabilities often face physical health issues, such as vision and hearing impairments.

    Assessment in Developmental Disabilities

    • Individuals with developmental disabilities are often overmedicated and undertreated due to caregivers' unfamiliarity with the nature of the disability.
    • Caregivers may overlook or misinterpret certain concerns, such as withdrawn behavior or loss of interests, which could indicate depression.
    • Professionals and paraprofessionals need specific training to understand the unique needs of this population.
    • The Scientific Problem-Solving Model of Psychological Assessment involves six steps: problem clarification, planning, development, implementation, evaluation, and dissemination.
    • Assessment in developmental disabilities aims to:
      • Identify strengths and needs
      • Determine appropriate interventions and services
      • Determine if an individual is experiencing a developmental disability or another condition
    • The assessment process is complex, involving multiple professionals and extending over a prolonged period.
    • Evidence-based strategies and interventions are recommended based on professional standards.
    • Assessment may involve individuals and groups.
    • Information gathered during assessment can include:
      • Health history
      • Social history
      • Characteristics
      • Skills
      • Knowledge and/or behavior
      • Environmental factors
    • Assessment is crucial for:
      • Identifying and implementing supports for learning, physical health, and mental health
      • Improving an individual's daily functioning
    • Reasons for individual assessments can include:
      • Identifying strengths and needs for educators
      • Identifying signs and symptoms of depression, potential causes, and available supports
      • Ongoing assessment for continuous support

    Integrating Quality of Life in Assessment & Intervention

    • Integrating quality of life concepts requires:
      • Examining the individual's life experiences and environment
      • Focusing on personal domains (family, friends, accommodations, work, leisure) and environmental domains (community resources, public safety)
    • Priorities for action should be established:
      • Basic necessities
      • Satisfaction with important aspects of life
      • Achieving fulfillment and meaning
    • Initial appraisal involves:
      • Determining individual strengths and needs
      • Identifying the individual's wishes
      • Determining the timeframe for assessment and intervention (short/long term, immediate/distant)
    • Assessment methods should be:
      • Objective
      • Standardized
      • Incorporate personal perceptions from the individual and others
      • Align with the individual's values and priorities
      • Shape information towards the individual's goals
    • Consider two key aspects:
      • Holism: Life is often viewed in parts but operates as an integrated whole.
      • Change over time: Acknowledge the dynamic nature of life experiences.

    Five Essential Assessment Actions

    • Attend to a situation or problem that has come to attention.
    • Gather information about the situation or problem.
    • Analyze strengths and needs.
    • Understand factors that help or hinder improvement.
    • Develop and implement plans to enhance positive factors and address hindering factors.

    Formal Assessment Frameworks

    • A formal assessment identifies needs and strengths in areas such as:
      • Intellectual functioning
      • Adaptive skills
      • Learning abilities and styles
      • Neurosensory functions
      • Speech and language skills
      • Health and medical conditions
      • Dental health
      • Nutrition
      • Neuropsychological issues
      • Life skills
      • Activities of daily living
      • Living environment
      • Available support

    Diagnosis and the Regulated Health Professions Act (RHPA)

    • The RHPA aims to:
      • Protect and serve the public interest
      • Create an open and accountable system of self-governance
      • Provide a modern framework for health professionals
      • Offer consumers freedom of choice
      • Improve quality of care
    • Key features of the RHPA include:
      • Scope of practice for each profession
      • Controlled acts that require qualified practitioners
      • Health regulatory colleges to govern each profession
      • Health Professions Regulatory Advisory Council to advise the Minister of Health and Long-Term Care
      • Health Professions Appeal and Review Board for independent review of registration and complaint decisions.

    Issues and Concerns in Making a Diagnosis

    • Who is responsible for making the diagnosis?
    • The reason for diagnosis must be understood.
    • A formal diagnosis designates a specific term describing a condition.
    • Diagnosis can be helpful in understanding an individual's needs and accessing resources, supports, and services.
    • Overuse of diagnosis and associated clinical issues should be considered.
    • Flexibility is allowed, especially in the DSM-5.
    • Diagnoses are often considered permanent.

    Challenges in Determining Disability

    • Policies for diagnosing disabilities are inconsistent.
    • Services require different aspects of the disability for eligibility.

    Assessment & Treatment Formulation

    • Assessment requires examining various factors including: identification of concerns, history of the concerns, client background information, supports background information, client examination, and support systems.
    • A good assessment should identify strengths and needs within the system.
    • Treatment focuses on reducing risk, decreasing organic contributions, decreasing stress, increasing competence, and a coordinated systems approach.

    Adaptive Behaviour Assessments

    • ABAS-3 assesses adaptive skills, including: communication, community use, functional academics, home/school living, health and safety, leisure, self-care, self-direction, and social.
    • ABAS-3 results in scaled scores that range from Superior to Extremely Low.
    • Vineland-3 is similar to ABAS-3 but also includes interview, parent/caregiver, and teacher forms.

    Treatment Principles

    • Treatment aims to maintain and improve life for those with disabilities.
    • Effective intervention should: address specific needs, set clear and achievable objectives, be based on sound rationale, use methods agreeable to the individual, ensure smooth transitions, and follow up, if needed.

    Types of Intervention

    • Therapy types include active focused therapies, age-related therapies (IBI, ABA), communication, education & training, health & medication, lifestyle & personal support, and personal & skill development.

    Intervention Specifics

    • Strategies include: addressing sensory impairments, treating seizures, managing medical disorders, providing appropriate environments and expectations, increasing coping skills, communication skills, self-esteem, social support, and a coordinated systems approach with continuity of care.

    Case Study: Michelle

    • Michelle exhibited self-injurious behaviour (SIB) from a young age.
    • Despite various interventions, her SIB persisted.
    • Michelle was treated with high doses of antipsychotics and other psychotropics with limited success.
    • A multidisciplinary assessment revealed a need for a coordinated system approach involving various local services.
    • Regular meetings between care partners ensured continuity of care and minimized crises.
    • Medication adjustments ultimately led to improvements in Michelle's quality of life and reduced SIB.

    Key Points

    • SIB arises from various circumstances and requires a stable and continuous setting for adequate assessment.
    • A multidisciplinary assessment approach is critical.
    • Antipsychotic medication prescription for challenging behaviours is no longer acceptable practice.

    Psychological Assessment

    • Is a system and problem-oriented process that is dynamic and conceptual.
    • It consists of problem clarification, planning, development, implementation, outcome determination, and dissemination.

    Psychological Testing

    • A set of skills, tactics, and strategies used in the assessment process.

    Percentile Scores

    • Rank-order scores that indicate a person's score relative to scores of others in the same age group who took the test.
    • Range from less than 1 to greater than 99.
    • A score of 40 indicates that the person scored better than 40% of test-takers but lower than the remaining 60%.
    • The average range is considered between the 25th and 74th percentiles.

    Normal Distribution or Bell Curve

    • Represents the distribution of intelligence in the population.
    • The average range for IQ standard scores is 90-110, with 8-12 representing the average range for scaled scores on subtests.

    Types of Validity

    • Content Validity: Ensures a test adequately samples relevant aspects of the construct being measured.
    • Criterion-Related Validity: Scores are shown to be related to specified external criteria, like performance on another measure or group membership.
    • Construct Validity: Confirms that the test actually measures the construct it claims to assess.

    Causes of Intellectual Disability

    • Obvious Physical Damage: Includes Down Syndrome, disease, teratogens, prenatal malnourishment, and injury.
    • No Obvious Signs of Brain Damage: A combination of genetic and environmental factors can contribute to intellectual disability.
    • Environmental Factors: Low parental IQ and a disorganized, deprived home environment.

    Conception and Genetics

    • Conception marks the beginning of human development.
    • A sperm fertilizes an ovum (egg cell) in the fallopian tube after the sperm travels through the vagina, cervix, and uterus.
    • Both sperm and ovum have 23 single chromosomes, and during fertilization, their chromosomes combine to form 46 chromosomes (23 pairs) in the zygote.
    • The Zygotic period, also known as the Germinal period.
      • The fertilized egg cell, called a zygote.
      • Cell division and differentiation into many cell types.
      • Pluripotent stem cells, which develop into various cell types.
    • The Embryonic period (Week 2-8 of pregnancy)
      • Major organ systems develop.
    • The Fetal period (End of Week 8 until birth)
      • Physical growth and maturation of organs.

    Genetic Principles

    • Chromosomes are thread-like structures carrying genetic material (DNA).
    • DNA is a double helix structure that consists of genes, which hold instructions for various functions.
    • Humans have 23 pairs of chromosomes, including sex chromosomes (X and Y).
    • Mitosis: Normal cell division, resulting in two identical daughter cells with a full set of 46 chromosomes.
    • Meiosis: Cell division specific to gametes (sperm and ova), with only half the number of chromosomes (23).
    • Alleles: Alternative forms of a gene.
    • Human Genome Project: Sequenced the entire human genome, including chromosome #20.

    Genetic Inheritance

    • Homozygous Pair: Two identical alleles for a specific gene, which can be dominant or recessive.
    • Heterozygous Pair: Two different alleles for a specific gene, which can result in dominant or recessive expression.
    • Phenotype: Observable characteristics of an individual.
    • Genotype: Genetic blueprint, the combination of alleles inherited.
    • Dominant-recessive pattern: A dominant gene always expresses its trait, while a recessive gene only expresses its trait when two recessive alleles are present.

    Inheritance Patterns

    • Polygenic Inheritance: Multiple genes interact to influence a single trait.
      • Ex: Eye color and height, with variations due to multiple genes.
    • Multifactorial Patterns: Both genes and environmental factors contribute to the expression of a trait.
    • Genomic Imprinting: Some genes have specific biochemical marks during ovum and sperm development, influencing their expression.
      • Ex: Prader-Willi syndrome (from the mother) and Angelman syndrome (from the father), both caused by defects on chromosome 15.
    • Mitochondrial Inheritance: Genes passed only from mother to child.

    Twins

    • Identical (Monozygotic) twins: Result from the splitting of a single fertilized ovum, leading to two genetically identical individuals.
    • Fraternal (Dizygotic) twins: Result from two separate eggs fertilized by two different sperm, resulting in two individuals with different genetic makeups.

    Prenatal Development Problems

    • Autosomal Disorders: Caused by errors on non-sex chromosomes.

      • Phenylketonuria (PKU): Lack of enzyme needed to metabolize phenylalanine, a protein, leading to intellectual disability.
      • Sickle-cell anemia: Red blood cells are sickle-shaped, causing anemia and other complications.
      • Tay-Sachs disease: Fatal genetic disease causing nerve damage and death by age 3.
      • Huntington's disease: Neurological disorder with degeneration of brain ventricles, usually starting in adulthood.

    • Sex-Linked Recessive Disorders: Carried on the X chromosome and more common in males.

      • Hemophilia: Bleeding disorder due to missing clotting factor.
      • Red-green colorblindness: Inability to distinguish certain colors.
      • Fragile X syndrome: Most common form of inherited intellectual disability, affecting mental development.
      • Turner syndrome (XO): In females, characterized by short stature, heart problems, and cognitive delays.
      • Klinefelter syndrome (XXY): In males, characterized by underdeveloped testes, low sperm count, and language/learning difficulties.
      • Triple X syndrome (XXX): In females, characterized by slow development, poor verbal skills, lower intelligence.
      • XYY syndrome: In males, characterized by taller than average height, large teeth, and normal development.

    Teratogens

    • Environmental agents that disrupt embryonic and fetal development, causing birth defects.
      • Examples: Alcohol, tobacco, chemotherapy drugs, caffeine, cocaine, lead, mercury, radiation, prescription drugs, etc.
    • Factors influencing teratogenicity:
      • Embryonic and fetal age (most vulnerable in early stages)
      • Dosage and duration of exposure.
      • Genetic susceptibility of the fetus and mother.

    Specific Genetic Disorders

    • Down syndrome (Trisomy 21): Caused by an extra copy of chromosome 21, it's the most common genetic cause of intellectual disability.
      • Distinctive facial features, physical abnormalities, heart problems, increased risk of seizures and Alzheimer's disease.
    • Prader-Willi and Angelman syndromes: Both caused by defects on chromosome 15, but exhibit different symptoms depending on parental origin.

    Genetic Factors in Mental Health Disorders

    • Genetic components: Research indicates genetic links to psychiatric disorders.
    • Higher proportion in individuals with developmental disabilities: Autism Spectrum Disorder (ASD) is an example.
    • Environmental factors: Multiple births, older fathers, exposure to medications or infections during pregnancy, neurotoxins.
    • Vaccination and autism: No causal link supported by scientific evidence.

    Inherited Genetic Metabolic Disorders

    • Defects in genes controlling metabolism: Affecting amino acids, sugars, carbohydrates, and nucleotides.
    • Examples: Prader-Willi and Angelman syndromes.

    Fragile X Syndrome

    • Fragile X Syndrome is the most commonly inherited form of developmental and intellectual disability.
    • Caused by a mutation in the FMR1 gene on the X chromosome.
    • Occurs across all cultures, not related to mother's age at conception.

    FMR1 Gene Mutation

    • The mutation involves an expansion of CGG repeats in the promoter region of the FMR1 gene.
    • Normal: 6-40 repeats
    • Premutation: 55-200 repeats (may cause FXPOI and FXTAS but not IDD)
    • Full mutation: 200+ repeats (gene may not work at all, often causes Fragile X Syndrome)
    • The size of the mutation affects the severity of symptoms.

    Symptoms of Fragile X Syndrome

    • Intellectual & Learning:
      • Wide range of intellectual functioning, from mild learning disorders to severe IDD.
      • May experience delays in speech, language acquisition, short-term memory, and spatial awareness.
      • Difficulty with attention, hyperactivity, and anxiety.
    • Physical:
      • Often not noticeable in infancy but may develop with age.
      • Features include a narrow face, large head, large ears, flexible joints, flat feet, and prominent forehead.
    • Behavioral, Social, & Emotional:
      • Often experience anxiety and trouble in new or unexpected situations.
      • May have difficulty with eye contact, social interaction, and attention.
      • May display aggression, shyness, or autistic-like characteristics.
    • Speech & Language:
      • Most boys experience speech and language difficulties, such as trouble speaking clearly, stuttering, or leaving out parts of words.
      • Girls usually have milder symptoms.
      • Some children with Fragile X may remain nonverbal throughout their lives.
    • Sensory Sensitivity:
      • Many experience sensory issues like sensitivity to bright lights, loud noises, or certain textures.

    Inheritance of Fragile X Syndrome

    • Can be inherited from both mother and father who carry the mutated FMR1 gene.
    • Males pass the mutated gene to all daughters but not sons.
    • Females have a 50% chance of passing the mutated gene to both sons and daughters.
    • Premutations can sometimes expand to full mutations during inheritance.

    Diagnosis of Fragile X Syndrome

    • Diagnosis typically involves a blood test to analyze the FMR1 gene.
    • Prenatal testing (amniocentesis or chorionic villus sampling) can detect the mutated gene in the developing fetus.
    • Average age of diagnosis for boys is 36 months and 42 months for girls.

    Treatment of Fragile X Syndrome

    • No single cure, but treatments aim to minimize symptoms.
    • Early intervention is critical for optimal development.
    • Key interventions include:
      • Educational support
      • Therapy services (occupational, physical, speech, and behavioral therapy)
      • Medications

    Prevalence of Fragile X Syndrome

    • 1 in 4,000 males and 1 in 8,000 females have Fragile X Syndrome.
    • Fragile X premutations are more common, affecting 1 in 151 women and 1 in 468 men.
