Learning Disabilities Flashcards

1
Q

What is a learning disability?

A

Learning disability is a general umbrella term encompassing a range of different conditions that affect the ability of the child to develop new skills.

Learning disabilities are heterogeneous conditions but are defined by 3 core criteria:
lower intellectual ability (usually defined as an IQ of less than 70)
significant impairment of social or adaptive functioning a
onset in childhood

Significant impairment in IQ and adaptive living with onset in childhood

Q

What are the types of learning difficulty - which may co-exist with learning disability?

A

Dyslexia refers to a specific difficulty in reading, writing and spelling.

Dysgraphia refers to a specific difficulty in writing.

Dyspraxia, also known as developmental co-ordination disorder, refers to a specific type of difficulty in physical co-ordination. It is more common in boys. It presents with delayed gross and fine motor skills and a child that appears clumsy.

Auditory processing disorder refers to a specific difficulty in processing auditory information.

Non-verbal learning disability refers to a specific difficulty in processing non-verbal information, such as body language and facial expressions.

Profound and multiple learning disability refers to severe difficulties across multiple areas, often requiring help with all aspects of daily life.

Q

What is challenging behaviour and how can the concept have problems?

A

Culturally abnormal behaviour of such an intensity, frequency and duration that the physical safety of the person or others is likely to be placed in serious jeopardy, or behaviour that is likely to seriously limit the use of or result in the person being denied access to ordinary community facilities

Vague, numerous meanings, used as a diagnosis so risk of diagnostic overshadowing, encourages consideration of causes rather than reasons

  • onset in childhood
33

  • Self-care
  • Home living
  • Social skills
  • Community use
  • Self-direction
  • Health and safety
  • Functional academics
  • Leisure
  • Work
34
Q

What IQ is considered borderline for learning disability?

A

70 - 84

35
Q

Limitations in the use of IQ in determining the classification of learning disability?

A

These categories have been criticized on the grounds that they omit any measure of social or adaptive functioning.

In addition, it has been argued that in practice IQ scores are often uncertain in people with more severe learning disabilities.

It is also widely recognised that IQ scores are not fixed throughout life, so provide only an approximate guide to intellectual ability.

Accordingly, many health and social care professionals
object to subdividing learning disabilities because such subdivisons create labels that are then used to describe people, often inaccurately.

Whatever subdivisions are used, a person with a milder degree oflearning disability may need support in only some areas (for example, budgeting, planning and time management).

The more severe a person’s learning disability, the more likely the person is to have very limited communication skills and a very significantly reduced ability to learn new skills. Likewise, the more severe the learning disability, the more likely the person is to need support with daily activities such as dressing, washing, eating, and mobility.

It is widely agreed that it is important to treat each person as an individual, with their own specific needs, and it is recognised that a broad and detailed assessment of needs is essential.

36
Q

  • Not classified as LD but still vulnerable due to
    cognitive status
  • Living independently
  • Subtle communication difficulties
  • High-school ‘drop-out’ or in special education

    assistance

    – Niemann-Pick disease
  • Mucopolysaccharidoses

45
Q

Challenging behaviors?

A

Some people with learning disabilities display behaviour that challenges. ‘Behaviour that challenges’ describes actions that often result from the interaction between individual and environmental factors.

It includes aggression toward others, self-injury, stereotypic behaviour (such as rocking or hand flapping), disruptive or destructive behaviour and withdrawn behaviour.

It can also include violence, arson or sexual abuse, thereby bringing the person into contact with the criminal justice system.

The most widely used definition of such behaviour is ‘culturally abnormal behaviour(s) of such intensity, frequency or duration that the physical safety of the
person or others is likely to be placed in serious jeopardy, or behaviour which is likely to seriously limit use, or result in the person being denied access to, ordinary community facilities

.Such behaviours increase the likelihood that restrictive and aversive management strategies will be used and can result in people being excluded from services and from ordinary community life.

57
Q

How might a clincian improve communication with a patient with an LD?

A

Look at the Communication Passport

Environmental alterations

Use simple language, check if they have
understood, clarify, avoid yes or no questions

Phrase questions carefully in order to avoid interrogative suggestibility

Give enough time for responses

Write things down / draw pictures to aid understanding

If the patient uses sign language (BSL, Signalong and Makaton)

Minimise wait times and increase consultation time

Explain the basics
– Who you are, why you are seeing them, how long it will take

Speak to patient before speaking to carer
* Get supporting information from carer

If anxious consider a short break, eat/drink, favourite
book/object, offer reassurance, one person takes lead

Continuity of care particularly important

58
Q

A
  • Limited communication skills
  • Difficult to assess thought disorder & hallucinations esp. in IQ<50
  • Diagnostic overshadowing ( automatically attributed the symptoms or disturbance to LD)

A
  • Limited coping strategies
  • Limited choices and opportunities
  • Limited social networks
  • Limited or adverse life experiences including discrimination, victimisation, multiple moves

  • Biological symptoms:
    – Sleep disturbance
