Age-related cognitive impairments, including Alzheimer's disease, are among the most common diseases in the United States. Prevention through delay is currently considered the best way to tackle Alzheimer's disease and related disorders (ADRD). Early detection is crucial, as screening individuals with Mild Cognitive Impairment (MCI) may delay its progression and prevent it from developing. This research investigates the role of technologies for senior citizens with potential MCI at-risk factors and for medical practitioners, such as neurologists or neuropsychologists, to make data-driven clinical decisions.The Clock Drawing Test, in which the patient is asked to draw a clock showing a certain time, is one of the easiest and most frequently used instruments for dementia screening. Current practice requires medical practitioners to administer and assess each individual paper-and-pencil test. It requires tedious effort and is prone to errors and inconsistent scoring among different clinicians. To address these difficulties, previous work by this research group has resulted in a computer-based version of the Clock Drawing Test that records a patient's freehand drawing on a tablet computer, then analyzes the drawing for evidence of cognitive imparment.The current project is extending the computer-based system to acquire additional data associated with the Clock Drawing Test. This data includes timing of drawing and pausing phases, and pressure applied during drawing. The data can be used in evaluating drawings under several different scoring critera that can be chosen by the clinician. Through analysis of data and focus group discussions, the clinical utility of the new features are being evaluated with a goal of further improvement.

与年龄有关的认知障碍，包括阿尔茨海默氏病，是美国最常见的疾病之一。目前，通过延迟预防被认为是解决阿尔茨海默氏病和相关疾病（ADRD）的最佳方法。早期检测至关重要，因为筛查患有轻度认知障碍的个体（MCI）可能会延迟其进展并防止其发展。这项研究调查了具有潜在MCI高风险因素的老年人的作用，以及神经系统或神经心理学家等医学医生做出数据驱动的临床决策的作用。要求患者绘制时钟测试，其中要求患者绘制一定时间，以显示一定时间，是摄入型摄入症的最常用工具之一。当前的实践要求医生管理和评估每个单独的纸笔测试。它需要繁琐的努力，并且容易出现不同的临床医生的错误和不一致的得分。 为了解决这些困难，该研究小组的先前工作导致了基于计算机的时钟绘图测试版本，该版本记录了患者在平板电脑上的徒手绘图，然后分析图形以获取认知障碍的证据。当前的项目正在扩展基于计算机的系统以获取与时钟图测试相关的其他数据。 该数据包括绘图和暂停阶段的时间，以及在绘图过程中施加的压力。 数据可用于评估临床医生可以选择的几个不同评分标准下的图纸。通过分析数据和焦点小组讨论，正在评估新功能的临床实用性，以进一步改进。
