Abstract
Cognitive impairment (CI) is defined as a mental impediment in independent function due to issues with memory recollection, behavior, emotional feelings and learning. Numerous forms of CI exist in varying severity from mild cognitive impairment (MCI) to Alzheimer’s disease (AD) and dementia. The complexity of these neurodevelopmental diseases and unknown causation has led to limitations in treatment options and consequent lack of a cure. To slow cognitive decline in patients with AD, sleep cognitive therapeutic devices are a developing field of treatment. Acoustic stimulation has been used in sleep studies to find improvements in cognitive function. The project team contributed to the development of a sleepwear device for patients with MCI, a potential precursor to AD. The ultimate product monitors polysomnographic activity, amplifying slow-waves for memory consolidation via live auditory stimulation. Product form factor ideation, designing, mock prototypes and material assembly were accomplished within the capstone term. CI can impose access barriers between CI users and digital devices. Impaired users typically require special features or frequent technical support. Advocates of persons with CI press for interface design changes or help users adjust. Above all, advocates seek to influence hardware and software companies early in the development process to bridge this gap in the digital divide.
