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...

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.

Source: Carmen Black, Matthew Goldenberg, and Jaideep Talwalkar; Yale School of Medicine The mental status exam is a clinical evaluation of emotional, perceptual, and cognitive functioning that spans both the fields of psychiatry and neurology. Developing skill in the psychiatric portions of the examination are important to describe salient aspects of the patient's mental state that may be observed during routine history and/or physical exam. Proficiency in the cognitive portions of this...
FAQs
Clinicians do not derive the result from walking ability alone. They consider impairments across several functional systems, including vision, motor function, coordination, sensation, and bladder or bowel control, then integrate those findings with walking performance and everyday activities. This combination provides a structured picture of neurological disability rather than focusing on one isolated symptom.
Walking ability strongly influences how disability is represented in the EDSS, especially when neurological impairment affects independence or daily movement. This emphasis makes the framework useful for tracking changes in ambulation, but it also means that some non-mobility problems may contribute less to the overall impression than their clinical importance might suggest.
The numerical score provides clinicians, patients, and researchers with a standardized way to describe the level of neurological disability and changes over time. Because the assessment combines several functional systems with walking and daily activities, the score can summarize complex findings in a form that supports clinical communication without replacing the underlying examination.
Repeated assessments allow clinicians to compare a person’s neurological function at different points in the course of care. Changes in functional-system findings, walking ability, or daily activities can be recorded through the framework, helping describe whether disability has changed and supporting evaluation of disease progression or response to treatment.
Clinical trials can use the EDSS to represent disability in a consistent, structured format across assessments. Its combination of neurological findings and functional ability gives investigators a way to evaluate changes associated with disease or treatment. The resulting scores also help communicate trial outcomes using a measure familiar within multiple sclerosis care and research.
An EDSS result should be interpreted alongside the individual functional findings rather than treated as a complete description of disability. The framework gives greater weight to mobility than to some other aspects of neurological function, so the numerical score may not fully convey the effect of vision, sensation, coordination, or bladder and bowel problems.
