Learning disabilities Flashcards
What is the definition of learning disabilities?
Significant impairment of intelligence = <70 IQ w impairment of adaptive functioning eg. ADLs. Both need to be present before adulthood.
Learning disability vs learning difficulty
Disability - affects learning and intelligence across all areas of life eg. Down’s syndrome
Difficulty - obstacle to a specific form of learning but doesn’t affect overall IQ eg. dyslexia
However learning difficulties are more common in the learning disability population.
What are the classes of learning disability?
Mild - IQ 50-69, some learning difficulties in school, independent w self care and often w living, capable of work, maybe delayed speech
Mod - IQ 35-49, delays in childhood but some degree of independence and communication skills
Severe - IQ 20-34, continuous need of support
Profound - IQ under 20, severe limited self-care skills, continence and communication
Not really important for treating a person.
What are some of the RFs for learning disabilities?
- Chromosomal and genetic anomalies eg. Down’s, William’s
- Congenital malformations eg. spina bifida, hydrocephalus
- Prenatal exposures eg. fetal alcohol syndrome, congenital rubella, Zika virus
- Birth complications eg. hypoxic brain injury, cerebral palsy
- Prematurity
- Childhood illness eg. meningitis, measles, encephalitis
- Childhood brain injury, neglect and lack of stimulation in early life
What conditions are more common in the learning disability population?

- Epilepsy - 40% of people w epilepsy have ID
- Higher rates mental illness

- ADHD
- Autism

What is involved in assessment of ID pt in ID psychiatry?
- Person w ID the focus of the consultation and check pt understanding
- Check collateral hx
- Mental state examination
- Risk assessment
What is involved in reducing premature death in learning disability pt?
- Standardisation of Annual Health Checks
- Referral to specialist learning disability services
- Named healthcare co ordinator to people w complex health needs
- Adults w learning disabilities considered high risk group for deaths from resp problems
- Used of the Mental Capacity Act to ensure decisions are made in the pt best interest
What are some complications of learning disabilities?
- Behavioural problems and their consequences eg. problems w criminality, inappropriate behaviour
- Sexual problems - sexually inappropriate behaviour
- Consequences of abuse eg. distress, increased mental health problems, pregnancy, STI
What adaptions are needed for seeing a pt w learning disabilities?

What is autism? What are the characteristics?
Neuro developmental condition characterised by:
- Difficulties w social interaction and communication - not good at sharing emotions, normal convo and non verbal communication, hard to maintain relationships
- Rigid and repetitive behaviours - repetitive motor movements, peculiar phrases, repetitive speech
- Resistance to change - inflexible routines
- Restricted interests, preoccupied w unusual objects
- Over reaction to normal sensations - hyper or hypo sensitive
What mental health problems do people w autism suffer with?
- Anxiety
- Challenging behaviour, often due to anxiety eg. meltdowns
- Depression
- OCD - repetitive behaviours
What is the management of autism?
- Help w learning how to interact socially
- Communication support eg. SALT and behavioural therapy
- Coping strategies for life skills

- Unusual characteristics of spoken language - echolalia, non speech like vocalisation

What is the trend of prescription of psychotropic medication in learning disability pt?
Antipsychotics and antidepressants have previously been overprescribed in the learning disability population. Some pt need them but many don’t and they have SEs that affect pt QOL:
- Putting on weight
- Feeling tired and lethargic - drugged up
- Serious problems w physical health
STOMP pledge - stopping over medication of people w a learning difficulty.
What is the use of pyschotrophic medication in learning disabilities?
- Those w learning disabilities have a higher rate of epilesy - anti epileptic drugs are appropriate here
- Those w learning disabilities have a higher rate of depression and anxiety - anti depressants are appropriate here
- Those w learning disabilities can have challenging behaviour, this should mostly be managed using behavioural strategies but in more severe cases antipsychotics may be needed, they may be appropriate here
- There are some appropriate uses but many pt are inappropriately on meds
