Down syndrome (DS) is the leading genetic cause of intellectual disability globally, affecting about 1 in every 800 births. Individuals with DS often face various neuropsychiatric conditions alongside intellectual disabilities due to altered brain development. Despite the diverse phenotypic expressions of DS, typical physical characteristics frequently influence language development and acquisition. EEG studies have identified abnormal oscillatory patterns in individuals with DS. Emerging interventions targeting the enhancement of gamma (40 Hz) neuronal oscillations show potential for improving brain electrical activity and cognitive functions in this population. However, effective cognitive interventions for DS remain scarce. Extensive research indicates that transcranial photobiomodulation (t-PBM) with near-infrared (NIR) light can penetrate deeply into the cerebral cortex, modulate cortical excitability, and enhance cerebral perfusion and oxygenation. Furthermore, t-PBM has been shown to improve cognitive functions such as language, attention, inhibition, learning, and memory, including working memory. This study presents the rationale and design of an ongoing randomized, sham-controlled clinical trial aimed at assessing the effectiveness of t-PBM using NIR light in enhancing the language abilities of individuals with DS.

It is proposed that all levels and functions of higher education should address the needs and characteristics of a rapidly increasing population of elderly in the United States. Some existing programs that have developed organizational structures to meet this need are presented as illustrations. (MSE)
