Objective
Quantitatively assess which treatment attributes are most important to people living with amyotrophic lateral sclerosis (ALS; pALS) in the United States (US) when making treatment decisions. Through direct and indirect assessment of preference, pALS indicated a desire for efficacious treatment options that improve physical functioning and survival.

Abstract
In this paper, we focused on another important aspect, cognitive impairment, which affects 35-50% of the ALS population. In an effort to reach the ALS population, which frequently exhibits mobility limitations, we implemented the digital version of the Edinburgh Cognitive and Behavioral ALS Screen (ECAS) test for the first time.

Abstract
We identified 285 anonymous Bing users whose queries indicated that they had been diagnosed with ALS and matched them to 1) 3276 control users and 2) 1814 users whose searches indicated they had ALS disease mimics. We tested whether the ALS group could be distinguished from controls and disease mimics based on search engine query data. Finally, we conducted a prospective validation from participants who provided access to their Bing search data. The model distinguished between the ALS group and controls with an area under the curve (AUC) of 0.81.

Abstract
We gathered survey data to identify the unmet needs expressed by Amyotrophic Lateral Sclerosis (ALS) patients, caregivers, and advocates. Natural Language Processing was used to summarize free text data. Identified needs, named anchor topics were selected manually from the data. Text embedding was used to score participant answers to anchor topics. Despite a broad range of opinions among cohorts, we detected pain control, better access to information and ALSFRS-R alternatives as
important ALS community issues. Natural Language Processing (NLP) and Artificial Intelligence (AI) was used to analyze the unstructured text data to obtain a deeper understanding of respondents’ answers.

Abstract
We investigate the utility of audiovisual dialog systems combined with speech and video analytics for real-time remote monitoring of depression at scale in uncontrolled environment settings. We collected audiovisual conversational data from participants who interacted with a cloud-based multimodal dialog system, and automatically extracted a large set of speech and vision metrics based on the rich existing literature of laboratory studies. We report on the efficacy of various audio and video metrics in differentiating people with mild, moderate and severe depression, and discuss the implications of these results for the deployment of such technologies in real-world neurological diagnosis and monitoring applications.

Objective
This presentation describes the creation of a large, open data platform, comprising speech and video recordings of people with ALS and healthy volunteers. Each participant is interviewed by Modality.AI’s virtual agent, emulating the role of a neurologist or speech pathologist walking them through speaking exercises [Fig 1] The collected data is made available to the academic and research community to foster acceleration of the development of biomarkers, diagnostics, therapies, and fundamental scientific understanding of ALS.
