Family flew man with dementia from L.A. to England, then abandoned him there, authorities allege

Los Angeles Times

Fifteen months ago, an elderly man with an American accent was found wandering around a British bus station parking lot disoriented. It took much detective work, but authorities now say that man is Earl Roger Curry, a 76-year-old Whittier man suffering from dementia. Los Angeles County officials and a British police investigation now allege he was simply dumped in England by his son during a visit, a charge his son, Kevin Curry, denies. Curry was returned to the United States by British authorities last year and is now in a Bellflower nursing home. "I've never seen one like this before.

Serious head injuries nearly double your risk of dementia

New Scientist

Serious head injuries nearly double a person's risk of developing dementia. That's the message from an analysis of over 40,000 people who sustained some kind of head injury between 1986 and 2014. Half the people in the study had moderate-to-severe head injuries, which cause lesions in the brain and require a person to stay in hospital for three days or more. The other half had milder head injuries with no lesions, and were able to go home within a day. Comparing the longer-term health of these two groups revealed that the risk of developing non-Alzheimer's dementia is 90 per cent higher in those with moderate-to-severe injuries, says Rahul Raj at the University of Helsinki, Finland.


Reinforcement Learning Models of Human Behavior: Reward Processing in Mental Disorders

arXiv.org Artificial Intelligence

For AI community, the development of agents that react differently to different types of rewards can enable us to understand a wide spectrum of multi-agent interactions in complex real-world socioeconomic systems. Empirically, the proposed model outperforms Q-Learning and Double Q-Learning in artificial scenarios with certain reward distributions and real-world human decision making gambling tasks. Moreover, from the behavioral modeling perspective, our parametric framework can be viewed as a first step towards a unifying computational model capturing reward processing abnormalities across multiple mental conditions and user preferences in long-term recommendation systems.


23andMe Is Suing Ancestry Over Some Pretty Ancient IP

WIRED

Heredity is so hot right now. In 2017, the number of people who who've had their DNA analyzed for the purposes of tracing their genealogy doubled to more than 15 million. The largest of these direct-to-consumer companies, Utah-based Ancestry, tested two million people in the last four months of 2017 alone. Which means there are a lot more people out there who could be tested, and the company that woos them can use their valuable data to do other kinds of research and product development. Genealogy products--tests that tell people where their ancestors hailed from and match them with distant family members--have captured the consumer imagination: People are much more likely to send in their saliva if it will tell them where they came from than if it will tell them their risk for Parkinson's disease.
