Eye-tracking system to diagnose ADHD 

Researchers at Tel Aviv University have developed a diagnostic tool that involves an eye-tracking system to monitor the involuntary eye movements in order to diagnose Attention Deficit Hyperactivity Disorder (ADHD) correctly. The researchers found that it accurately reflected the presence of ADHD, as well as the benefits of medical stimulants that are used to treat the disorder.

Dr. Moshe Fried, of TAU’s Sackler Faculty of Medicine, said that they had two objectives going into this research: the first was to provide a new diagnostic tool for ADHD, and the second was to test whether ADHD medication really works.The researchers found a direct correlation between ADHD and the inability to suppress eye movement in the anticipation of visual stimuli.

They also reflected improved performance by people who took methylphenidate, which normalized the suppression of involuntary eye movements to the average level of the control group. According to the Centers for Disease Control and Prevention, ADHD has been the most commonly diagnosed and misdiagnosed behavioural disorder and there are currently no reliable physiological markers to diagnose ADHD.
‘Careless’ drunks aware and conscious of their actions

A new study has shown that people who are drunk know what they do but they don’t care because alcohol merely cuts out their natural “alarm signals”. 

According to news.com.au, Bruce Bartholow said that it was very common for people to respond more slowly following an error, as a way of trying to regain self-control but the alcohol group participants didn’t do this. He asserted that the role of alcohol was merely to silence the “alarm signals” that warned them to control themselves or difficult social consequences may ensue.  Poor sleep increases suicide risk in older adults

Older adults who complain of poor sleep quality, independent of a depressed mood, are at increased risk for suicide, concluded a study by Stanford University School of Medicine. 

Two sleep factors in particular - difficulty falling asleep and non-restorative sleep - were associated with increased risk. “We suggest that poor subjective sleep quality may represent a useful screening tool and a novel therapeutic target for suicide prevention in late life,” said Rebecca Bernert.

The study sample included 420 individuals who were selected from 14,456 participants. The researchers examined the risk for suicide associated with poor reported sleep in during a 10-year observation period. 

Those individuals who reported poorer sleep quality at baseline had a 1.4 times increased risk for suicide. When the researchers controlled for the effects of a depressed mood, people with poorer sleep at baseline still demonstrated a 1.2 times greater risk. ‘Ticking clocks’ can spur women’s fertility alarm

Research has revealed that the subtle sound of a clock ticking can quite literally speed up a woman’s biological clock, and could lead her to start a family at an early age, especially if she was raised in a lower socio-economic community.

Reproductive timing refers to the time frame and the specific years during which people begin to focus their energy and resources towards bearing and caring for their offspring. 

The findings suggested that priming the idea of the passage of time through the sound of a ticking clock could influence various aspects of women’s reproductive timing. The effect was especially noticeable among women from lower socio-economic backgrounds. They wanted to get married and have their first child at a younger age than women with more resources. They also lowered the priority that they placed on men’s social status and long-term earning potential.

However, the effect of the clock did not do the same for men because men are able to father children well into their old age. Their reproductive lives are therefore not as limited as that of women.
