Quantitative Assessment of Cortical Auditory-tactile Processing in Children with Disabilities

Objective and easy measurement of sensory processing is extremely difficult in nonverbal or vulnerable pediatric patients. We developed a new methodology to quantitatively assess infants and children's cortical processing of light touch, speech sounds, and the multisensory processing of the 2 stimuli, without requiring active subject participation or causing discomfort in vulnerable patients.

Intellectual Disability

2025
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...

Learning 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. Dyslexia Dyslexia is a...

Half-life of a Reaction

2020
The half-life of a reaction (t1/2) is the time required for one-half of a given amount of reactant to be consumed. In each succeeding half-life, half of the remaining concentration of the reactant is consumed. For example, during the decomposition of hydrogen peroxide, during the first half-life (from 0.00 hours to 6.00 hours), the concentration of H2O2 decreases from 1.000 M to 0.500 M. During the second half-life (from 6.00 hours to 12.00 hours), the concentration decreases from 0.500 M to...
FAQs
The mortality component captures healthy years lost when people die earlier than expected, while the disability component captures time affected by a health condition. Adding these components prevents disease burden from being represented solely by death counts. This makes DALYs useful for recognizing conditions that cause substantial disability even when they do not produce high premature mortality.
Severity and duration determine how heavily time lived with a health condition contributes to the estimate. A more severe condition receives greater weighting, while a longer-lasting condition contributes across more time. Considering both factors allows the measure to distinguish brief, mild conditions from prolonged or severe health problems when estimating their effects on healthy life.
Mortality statistics emphasize deaths, but DALYs also account for healthy time lost through disability. Consequently, the measure can show that a condition has a substantial population burden even when its death count is relatively limited. This broader perspective supports comparisons among diseases, injuries, and risk factors that affect health in different ways.
Researchers first estimate years of life lost from premature deaths, then estimate years lived with disability by considering the duration and severity of health conditions. They add these two components to obtain the population total. The resulting figure can be examined across diseases, injuries, risk factors, populations, or time periods to characterize differences in health burden.
Health systems can compare the burden associated with different diseases, injuries, and risk factors using a common population health measure. These comparisons help identify conditions producing the greatest loss of healthy life and inform priority setting. In practice, the results can support decisions about which health problems deserve focused planning, prevention, or service attention.
By comparing DALY estimates across time, researchers and health systems can assess whether population health burden has changed. A reduction may indicate fewer premature deaths, less disability, or improvement in both components. The same framework also supports evaluation of interventions by showing whether the conditions they target contribute fewer lost healthy years after implementation.
