Detecting dementia with automated speech analysis

WinterLight Labs is developing speech analyzing algorithms to detect and monitor dementia and aphasia.  A one minute speech sample is used to determine the lexical diversity, syntactic complexity, semantic content, and articulation associated with these conditions. Clinicians currently conduct similar tests by interviewing patients and writing their impressions on paper. The company believes that their […]

Robotic, in-vivo neuron recording

Ed Boyden and MIT colleagues have developed a robotic system capable of monitoring specific neurons. An algorithm based on multiple image processing methods analyzes microscope images and guides a robotic arm to within 25 microns of a target cell. The system then relies on both imagery and impedance, which more accurately detects contact between the […]

Google incorporates depression screening in search

Google has introduced a new depression screening feature.  When the word “depression” is used in search, mobile users are offered a PHQ-9 questionnaire, which recognizes symptoms. A “Knowledge Panel” containing information and potential treatments appears on top of the page. The goal is self awareness, and encouragement to seek help when needed. Another company dedicated to […]

Small, adhesive, wireless patch collects, transmits, extensive health data

Northwestern’s John Rogers and Kyung-In Jang of the Daegu Gyeongbuk Institute of Science and Technology have developed a small, adhesive, flexible silicone patch capable of monitoring multiple health parameters. The soft, body-conforming wearable contains 50 components connected by  250  3-D wire coils embedded in protective silicone.  It collects and wirelessly transmits data about movement, respiration, and […]

Machine learning for early Alzheimer’s diagnosis

Anant Madabhushi and Case Western colleagues have used machine learning to diagnose Alzheimer’s disease via imaging data in a small study.  The goal is early intervention, which could potentially extend independence. 149 patients were analyzed using a Cascaded Multi-view Canonical Correlation (CaMCCo) algorithm, which integrates MRI scans, features of the hippocampus, glucose metabolism rates in the […]

Apple patents multi-parameter, phone-based health tracking

Apple  has been granted a patent for phone technology using a front-facing camera and light, proximity, and multiple sensors to measure body fat, heart rate, circulation, blood pressure, and breathing, as well as emotional state via galvanic skin response. The device computes health data of the user based upon sensor data regarding the received light. It has been reported […]

Single blood draw detects 1250 pathogens from cell-free DNA

Karius‘s  next-generation sequencing detects fragments of 1250 microbes from a single blood draw.  Identifying microbial cell-free DNA from bacteria, viruses, fungi and protozoa can facilitate the rapid diagnosis of infectious disease.  Current diagnostics only detect a narrow range of pathogens, and may require invasive biopsies. This fast and comprehensive analysis could enable more effective, targeted […]
