How does Down syndrome affect cognition?

The cognitive phenotype in Down’s syndrome is characterised by impairments in morphosyntax, verbal short-term memory, and explicit long-term memory. However, visuospatial short-term memory, associative learning, and implicit long-term memory functions are preserved.

How does Down syndrome affect cognitive?

Cognitive impairment, problems with thinking and learning, is common in people with Down syndrome and usually ranges from mild to moderate. Only rarely is Down syndrome associated with severe cognitive impairment. Other common cognitive and behavioral problems may include1,2,3,4: Short attention span.

Does Down syndrome affect intelligence?

Most individuals with Down syndrome have mild (IQ: 50–69) or moderate (IQ: 35–50) intellectual disability with some cases having severe (IQ: 20–35) difficulties. Those with mosaic Down syndrome typically have IQ scores 10–30 points higher.

Which aspects of cognition are affected in Down syndrome and how is cognition impacted by Ageing?

People with Down syndrome often experience a gradual decline in thinking ability (cognition) as they age, usually starting around age 50. Down syndrome is also associated with an increased risk of developing Alzheimer disease, a brain disorder that results in a gradual loss of memory, judgment, and ability to function.

How does having Down syndrome affect thinking planning and problem solving cognitive development?

[e.g.12,13] The questionnaire studies indicate that children with Down syndrome tend to show specific difficulties in working memory and planning but not in shifting or emotional control when compared with mental age matched typically developing children.

What are the mental characteristics of Down syndrome?

They often have mild to moderate intellectual disability and may have specific challenges with attention span, verbal memory and expressive communication. Behavioral problems such as stubbornness, impulsivity and temper tantrums may be more common in children with Down syndrome.

How does Down syndrome affect intellectual development?

Down syndrome can affect learning abilities in different ways, but it usually causes mild to moderate intellectual impairment. Children with Down syndrome have delays in speech and motor skills, and may need help with self-care, such as dressing and grooming.

Do all Down syndrome have intellectual disability?

All people with Down’s syndrome will have some degree of intellectual disability. Children with Down’s syndrome do learn to walk, talk and be toilet trained but in general will meet these developmental milestones later than their non-disabled peers.

How cognition can be affected as a result of the Ageing process?

The most important changes in cognition with normal aging are declines in performance on cognitive tasks that require one to quickly process or transform information to make a decision, including measures of speed of processing, working memory, and executive cognitive function.

How changes to the brain can impact cognitive functioning?

Neuronal Changes

The number of connections, or synapses, between brain cells also drops, which can affect learning and memory. Although synaptic changes are selective and subtle, their effect on cognitive decline is believed to be greater than the effects of structural and chemical changes.

How does Down syndrome affect development and learning?

Learning difficulties

All children with Down’s syndrome suffer a degree of developmental difficulty; children with Down’s syndrome tend to develop slower than other children and they have trouble learning new concepts and retaining information.

What body systems are affected by Down syndrome?
