Chronic stress activates behavioral problems like loss of pleasure, depression Health

It’s clear that chronic stress can impact our behavior, leading to problems like depression, reduced interest in things that previously brought us pleasure, and even PTSD. Now scientists have evidence that a group of neurons in a bow-shaped portion of the brain become hyperactive after chronic exposure to stress. When these POMC neurons become super … Read more

Research sheds light on opportunities and constraints in self-directed care during the pandemic

As the US population ages, the number of people receiving long-term services and supports in their own home has grown, including the use of self-directed care. Self-directed care enables long-term care recipients to hire and manage their own workers, rather than using a home care agency. The COVID-19 pandemic increased the strain on this industry. … Read more

Wearable cardiac ultrasound imager gives critical insight about the heart in real time

Heart disease is the leading cause of death worldwide. In the US, it is estimated that someone dies every 34 seconds from cardiovascular disease. Diagnosis for heart disease remains a challenge, as most methods only provide a snapshot of cardiac function, which may not be representative of overall heart health. Improvements in diagnostic technologies could … Read more

Targeting the newly discovered signaling pathway could boost the potency of cancer therapeutics

Cells zealously protect the integrity of their genomes, because damage can lead to cancer or cell death. The genome -; a cell’s complete set of DNA -; is most vulnerable while it is being duplicated before a cell divides. Cancer cells are constantly dividing, so their genomes are constantly in jeopardy. Researchers at Washington University … Read more

Neurons in a bow-shaped brain region become hyperactive after chronic stress exposure

It’s clear that chronic stress can impact our behavior, leading to problems like depression, reduced interest in things that previously brought us pleasure, even PTSD. Now scientists have evidence that a group of neurons in a bow-shaped portion of the brain become hyperactive after chronic exposure to stress.

Why Does It Happen And How To Prevent It

The dangers of gaining weight include diabetes and increased blood pressure and so on Cortisol can increase your hunger because it stimulates the release of insulin, which is necessary to keep your blood sugar levels stable. Weight gain could result if you give in to those cravings. In fact, studies suggest that those who are … Read more

New imaging system reveals how female and male hearts respond differently to stress hormone

A new study published in Science Advances shows female and male hearts respond differently to the stress hormone noradrenaline. The study in mice may have implications for human heart disorders like arrhythmias and heart failure and how different sexes respond to medications. The team built a new type of fluorescence imaging system that allows them … Read more

An acupuncturist and pain expert shares the 2 pressure points she uses to ‘quickly relieve headaches’

Tension headaches are no joke. They typically feel like a tight band around the head, and can stem from muscle contractions in the head and neck, stress or even poor posture. Many people take pain medications like acetaminophen and NSAIDs (non-steroidal anti-inflammatory drugs) to relieve symptoms. But overusing them without medical guidance can lead to … Read more

Study shows link between older adults with asthma and depression risk during the COVID-19 pandemic

A recent, prospective study of approximately 2,000 older adults in Canada published online this month in the journal Respiratory Medicine found that older adults with asthma were at high risk of depression during the COVID-19 pandemic. For older adults with asthma who had experienced depression in the past, the numbers were extremely worrying, with approximately … Read more

Researchers identify a specific neural mechanism behind remembering emotional events

Most people remember emotional events, like their wedding day, very clearly, but researchers are not sure how the human brain prioritizes emotional events in memory. In a study published January 16, 2023, by Nature Human Behaviour, Joshua Jacobs, associate professor of biomedical engineering at Columbia Engineering, and his team identified a specific neural mechanism in … Read more
