Adult attention-deficit/hyperactivity disorder and the risk of dementia

JAMA Network Open

2023-10-17

(Press-News.org) About The Study: In this study of 109,000 individuals born between 1933 and 1952 and followed up in old age, adult attention-deficit/hyperactivity disorder (ADHD) was associated with an increased risk of dementia. Policy makers, caregivers, patients, and clinicians may wish to monitor reliably for ADHD in old age.

Authors: Stephen Z. Levine, Ph.D., of the University of Haifa in Haifa, Israel, is the corresponding author.

AI models identify biodiversity from animal sounds in tropical rainforests

2023-10-17

Tropical forests are among the most important habitats on our planet. They are characterised by extremely high species diversity and play an eminent role in the global carbon cycle and the world climate. However, many tropical forest areas have been deforested and overexploitation continues day by day. Reforested areas in the tropics are therefore becoming increasingly important for the climate and biodiversity. How well biodiversity develops on such areas can be monitored very well with an automated analysis of animal sounds. This was reported by researchers in the journal Nature Communications. Recordings on Former Cocoa Plantations and Pastures As part of the DFG research group ...

Recognizing clinical signs of hyperthyroidism leads to appropriate treatments, reduces adverse impact on health

2023-10-17

(Boston)—Untreated hyperthyroidism, conditions where there is excess thyroid hormone present, can adversely affect health, leading to increased risks for abnormal heart rhythms, heart failure, osteoporosis, adverse pregnancy outcomes, metabolic abnormalities and increased mortality risk. Hyperthyroidism can occur due to several different etiologies, including Graves’ disease, toxic (overactive) thyroid nodules, and thyroiditis. It is important to recognize, correctly diagnose, and appropriately treat the underlying cause of hyperthyroidism to minimize its impacts on health. In a new review article in the Journal ...

Adults with ADHD are at increased risk for developing dementia

2023-10-17

Adults with attention-deficit/hyperactivity disorder (ADHD) are nearly three times more likely to develop dementia than adults without ADHD, according to a Rutgers study. The study, coauthored by Michal Schnaider Beeri, director of the Herbert and Jacqueline Krieger Klein Alzheimer’s Research Center at Rutgers Brain Health Institute (BHI) was published in JAMA Network Open. It followed more than 100,000 older adults in Israel over 17 years to examine if adults with ADHD are at increased risk for dementia, including Alzheimer’s disease. Although more than 3 percent of the adult population in the United States has ADHD, there is limited research ...

Orchid without bumblebee on island finds wasp, loses self

2023-10-17

Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Kobe University researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances. Remote islands have been exciting study grounds for biologists since at least the days of Darwin. When studying ecological relationships between different species, the differences between mainland and island ...

Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics

2023-10-17

Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors. Numerous studies have shown that global microplastic quantities in the marine environment are increasing, even in remote locations such as the Arctic. The Barents Sea, which adjoins the Arctic Ocean, is one of the most productive oceanic areas in the world and home to an enormous diversity of organisms. It is also a key route for Atlantic ...

Boosting weak immune system: scientists find an unusual weapon against virus

2023-10-17

Some viruses can be dormant throughout a person’s life and cause no harm but become dangerous when the immune system is weakened. One of such viruses is human cytomegalovirus (CMV). Harmless to the general public but life-threatening to patients with a supressed immune system. “Patients undergoing bone marrow transplantations have their blood and immune system fully replaced by that of the donor. In the first months after transplantation they are defenseless. They can either catch CMV or have virus reactivated that was dormant in the patient. At the moment, there is no ideal treatment. The available ones work ...

Depression, anxiety common among college students

2023-10-17

Depression and anxiety among college students is a growing public health problem. And new research from the University of Georgia suggests the problem may be worse for students who aren’t the same race as most of their peers. The new study found that students who were not the majority race at a predominantly white college reported significantly higher rates of depression than their white peers. At the mostly white university, more than half of the students who self-identified as races other than white reported feelings of mild depression. An additional 17% said they were experiencing moderate to severe depression. Students at the predominantly ...

Research finds water quality in Gulf of Mexico improves when adding social costs to carbon emissions

2023-10-17

DURHAM, N.H.—U.S. Climate policies can offer options for putting climate change efforts into place that solve environmental problems like excessive carbon dioxide in the atmosphere created by greenhouse gas emissions. Research led by the University of New Hampshire took a closer look at what would happen to agriculture if there was an extra cost, or so-called social cost, added to fossil fuels, which are essential for making fertilizer used in farming. They found that while CO2 emissions would decline by as much as 50%, the cost of fertilizer would rise leading to a significant benefit on water quality by lessening fertilizer runoff contributing ...

Mitigating electrode-level heterogeneity using phosphorus nanolayers on graphite for fast-charging batteries

2023-10-17

In a major stride towards achieving fast-charging lithium-ion batteries (LIBs) with reliable cyclability, researchers at UNIST have made a groundbreaking discovery. Their study, published in the prestigious ACS Energy Letters, introduces a novel strategy of utilizing phosphorus nanolayers to enhance the lithiation kinetics and performance of graphite-based composites, without compromising safety. Led by Professor Hyun-Wook Lee from the School of Energy and Chemical Engineering at UNIST, the research team developed a revolutionary graphite-phosphorus composite using a vaporization-condensation ...

In 2020, 30% of the Pantanal was burned to cinders by wildfires

2023-10-17

In 2020, the Pantanal, the largest tropical freshwater wetland in the world and a biodiversity hotspot, was swept by high-intensity fires that destroyed native vegetation in an area totaling 44,998 square kilometers (km²), or about 30% of the Brazilian portion of the biome, which spans some 150,000 km². The estimate is presented in an article published in the science journal Fire. The area destroyed by that year’s disastrous fires was far larger than had been thought, according to the article. ...
