Developmental Disabilities Research Reviews
|August 17, 2013
Summary
Researching aging, health, and mortality in adults with rare intellectual disabilities faces challenges. Studies on Prader-Willi and Williams syndromes offer insights into aging in these rare neurodevelopmental disorders.
Area of Science:
- Gerontology
- Genetics
- Neurodevelopmental Disorders
Background:
- Research on aging, health, and mortality in adults with rare intellectual disability syndromes is limited.
- Existing studies face significant methodological obstacles.
Purpose of the Study:
- To highlight methodological challenges in aging research for rare intellectual disabilities.
- To review aging in Prader-Willi and Williams syndromes for insights into phenotypic expression and treatment.
- To provide recommendations for future research in this understudied area.
Main Methods:
- This review synthesizes existing literature on aging in rare intellectual disabilities.
- It specifically examines aging in Prader-Willi and Williams syndromes.
- Recommendations are based on current genetic advances and observed adult phenotypes.
Main Results:
- Key challenges include accurate diagnosis ascertainment, healthcare access, cohort differences, and survival biases.
- Aging in Prader-Willi and Williams syndromes reveals specific phenotypic changes and treatment considerations.
- Despite obstacles, aging individuals with rare disorders offer valuable research data.
Conclusions:
- Aging in rare neurodevelopmental disorders is an under-researched field with significant potential for discovery.
- Addressing methodological challenges is crucial for advancing knowledge in this area.
- Future research should leverage genetic advancements and inter-syndrome collaboration.

01:29Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:30Cognitive Development During Adulthood
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
