Q

In twin studies, what % of ASD is heritable?

1 - 0-9%
2 - 20-29%
3 - 40-50%
4 - 75-90%

A

4 - 75-90%

  • if a sibling has ASD, then theres a 10-20% chance of another sibling developing ASD
17
Q

Although not the only cause, imaging has identified some changes in the brain in patients with ASD. Changes in which of the following has NOT been linked with autism?

1 - Frontal lobe
2 - Occipital lobe
3 - Limbic system
4 - Temporal lobe
5 - Corpus Callosum
6 - Cerebellum

A

2 - Occipital lobe

  • ASD brains are often described as disorganised
  • image shows 2 patients brain activity after being asked to talk about a social event
18
Q

Although genetics plays a key role in the aetiology of ASD, there are other factors as well. One of these is organic brain disorder. What is this?

1 - children’s brains developing faster in childhood
2 - inability to judge what people are thinking and use the knowledge to predict their behaviour (lack of theory of mind)
3 - adverse events in perinatal period (pregnancy and first 12 months of life)

A

1 - children’s brains developing faster in childhood

19
Q

What is theory of mind?

1 - ability to process emotions and thoughts
2 - ability to judge what people are thinking and use the knowledge to predict their behaviour
3 - ability to process information and think about alternatives

A

2 - ability to judge what people are thinking and use the knowledge to predict their behaviour

  • this is hypothesised to be the main deficit in ASD
20
Q

Patients with ASD are often described as having sensory integration that can be hypo or hypersensitive. Which of the following are examples?

1 - deep pressure blankets
2 - response to pain (often higher threshold for pain)
3 - trampolines and rocking chairs
4 - all of the above

A

4 - all of the above

  • trampolines and rocking chairs are generally because some ASD patients can have a dysfunctional vestibular system
21
Q

Is understanding sensory integration important in patients with ASD?

A
  • yes
  • if we know what is hypo and hyper, we can use them to manage patients
22
Q

Patients with ASD can have meltdowns or shutdowns. How are these typically managed?

1 - wait and see
2 - pharmacotherapy
3 - restraint
4 - all of the above

A

1 - wait and see
- patients with ASD need time to process, so give this to them

23
Q

Do children and adolescents with the features of ASD, such as abnormal behaviour continue into adulthood to the same extent?

A
  • can, but with behavioural intervention they can improve and become less socially impairing
24
Q

What % of children with ASD attend a regular school in the UK?

1 - 7%
2 - 20%
3 - 40%
4 - 70%

A

4 - 70%

  • its 20% in the USA
25
Q

Patients with ASD are often at increased risk of comorbidities. Which of the following is NOT a common comorbidity in ASD?

1 - anxiety

A

3 - dementia

Q

All of the following are mental disorders that typically occur in ASD. Which is the most common?

1 - ADHD
