Poor sleep may point to onset of Alzheimer’s disease: study

Poor, disrupted sleep may indicate the risk of developing Alzheimer’s disease in people who are otherwise healthy, a study warns. Researchers from University of Wisconsin-Madison in the US found that people who reported worse sleep quality, more sleep problems and daytime sleepiness had more biological markers for Alzheimer’s disease in their spinal fluid than people who did not have sleep problems. Those biological markers included signs of the proteins amyloid and tau and brain cell damage and inflammation. “It’s important to identify modifiable risk factors for Alzheimer’s given that estimates suggest that…

Sugar intake in pregnancy ups allergy, asthma risk in baby

High intake of sugar during pregnancy may increase the risk of allergy and asthma in the baby, a study has found. While some research has reported an association between a high consumption of sugar-containing beverages and asthma in children, the relation between maternal sugar intake during pregnancy and allergy and asthma in the offspring has been little studied. Researchers from University of Bristol and Queen Mary University of London (QMUL) in the UK collected data from almost 9,000 mothers who were pregnant in the early 1990s and their offspring. The study, published…

Digital devices blamed for dry eye problem among children

There is an increase in dry eye symptoms among younger patients due to excessive use of digital devices, a study has said. Dr Amber Gaume Giannoni, a local optometry specialist with the College of Optometry at the University of Houston, on Wednesday said the more children stare at a screen, the less they tend to blink, which results in dry eye symptoms, because blinking helps stimulate the glands used to moisturise the eyes. The study also showed that children as young as eight can spend six hours a day in…

How does prenatal alcohol exposure raise addiction risk

Babies’ exposure to alcohol in the womb causes alteration in the brain’s reward system, which then increases their risk for drug addiction later in life, according to a study. The key appears to lie with endocannibinoids — cannabis — like chemicals that are produced by the brain itself, the research showed. After the prenatal brain is exposed to alcohol, these endocannibinoids impact certain dopamine neurons — that are involved in addicted behaviours. The endocannibinoids weaken the excitatory synapses onto dopamine neurons, in the ventral tegmental area (VTA) — part of…

Marijuana may up psychosis risk in teenagers: Study

Daily consumption of marijuana may increase an adolescent’s risk of having recurrent psychotic-like experiences by 159 per cent, according to a new study. The psychotic-like experiences include the experiences of perceptual aberration — for example feeling that something external is part of their body — and thinking that they have been unjustly badly treated. “Our findings confirm that becoming a more regular marijuana user during adolescence is, indeed, associated with a risk of psychotic symptoms,” said lead author Josiane Bourque, doctoral student at the Universite de Montreal (UdeM) in Canada.…

Childhood obesity may lead to hip disease, suggests research

Obesity may put children at increased risk of hip disease, a condition that can cause life-long morbidity, suggests new research. Slipped Capital Femoral Epiphysis (SCFE) is the most common hip disease of adolescence. The condition always requires surgery, can cause significant pain, and often leads to a hip replacement in adolescence or early adulthood. “Ultimately this study helps us to better understand one of the main diseases affecting the hip in childhood,” said one of the study authors Daniel Perry from the Institute of Translational Medicine, University of Liverpool, in…

Anti-gravity treadmill may boost confidence post knee surgery

Using space age technology, a British scientist has developed an anti-gravity treadmill that can help people reduce their fears of re-injury as well as boost their confidence after knee operations. “The anti-gravity treadmill could provide a great environment for healing and help restore the belief that injured people could make a successful return to any sport they love,” said Karen Hambly, senior lecturer at the University of Kent and an international expert on knee rehabilitation. When people run, the load on their knee joints could be up to five times…

How lifting heavy weights boosts muscle strength

Lifting heavy weights may help you enhance your muscle strength more than light weight training because the nervous system facilitates improvements in strength during high-load training, researchers suggests. The study aimed to find out how the brain and motor neurons — cells that send electrical signals to muscle — adapt to high versus low-load weight training. The findings showed that despite similar increases in muscle thickness, high-load training may be superior for enhancing muscle strength than low-load training. The nervous system activates more of the motor neurons — or excites…

Having a purpose in life can help you sleep better : Research

Older adults who live with a purpose in life are more likely to have a good night sleep and less sleep apnoea as well as restless leg syndrome, a study has showed. Individuals have more sleep disturbances and insomnia as they get older. But, the findings demonstrated that people who felt their lives had meaning were 63 per cent less likely to have sleep apnoea — shallow breathing or pauses in breathing during sleep, several times per hour. Further, they were 52 per cent less likely to have restless leg…
