High Blood Pressure Implicated in Cognitive Impairment

A new study has discovered that patients with high blood pressure and abnormalities in the  periventricular white matter in the brain showed signs of cognitive impairment despite taking medication to lower their blood pressure.

High blood pressure has been linked to an increased risk for dementia, but what’s unclear is what kinds of subtle negative changes take place in the brain that may affect cognitive function, according to researchers. Finding new ways to detect minor types of cognitive impairment may help determine who is at risk for early-stage dementia, they noted.

In the study, researchers looked at 345 men and women with a median age of 65 who had high blood pressure.

Patients underwent brain imaging scans, were tested in cognitive function areas including execution, memory, and attention, and were followed for about four years.

Average blood pressure during follow-up was 144.5/76.5 mm Hg. The American Heart Association/American College of Cardiology 2017 hypertension guidelines revised the definition of hypertension, classifying it as a blood pressure reading of 130/80 mm Hg instead of 140/90.

To understand what was going on in the brain, researchers looked at the white matter. White matter is important because it connects different regions of the brain, serving as a kind of infrastructure, the researchers explain.

Specifically, researchers looked at periventricular white matter, located in the central part of the brain, which acts as a bridge between distant brain regions and serves an important role in cognitive function. Lesions or abnormalities found in periventricular white matter could signal cognitive impairment, they note.

During the study, 9 percent of the group developed mild cognitive impairment. There was also a connection between periventricular white matter changes and the risk of mild cognitive impairment. Researchers found that patients with a progression of periventricular white matter abnormalities showed a six-fold increased risk of mild cognitive decline.

The researchers observed that the progression of periventricular white matter abnormalities aligned with cognitive decline in global and executive function. Small vessel bleeding in the brain was found to be related to a decline in attention, they add.

Although the development of brain lesions may be considered “silent” conditions in which patients do not feel or are unaware of symptoms, if left untreated, the risks of more severe forms of cognitive decline may increase, the researchers said.

They added that more study is needed to better understand how periventricular white matter changes triggers cognitive decline.

“The brain is an organ exposed to a high volume of blood flow and it is very vulnerable to sustained high blood pressure levels, and this might be happening silently or with mild symptoms, but that doesn’t mean there aren’t consequences,” said lead author Joan Jiménez Balado, Ph.D. ,M.Sc. in Neuroscience at the Institut de Recerca Hospital Vall d’Hebron in Barcelona, Spain.

“High blood pressure and its consequences are really ‘covert’ diseases that tend to progress if it is not well managed.”

The study was published in the American Heart Association’s journal Hypertension.

Working Remotely Is Not Necessarily Stress-Free

Many believe that working from home or remotely can foster freedom and stress-free job satisfaction, and that everyone wants  more work autonomy. A new study from Baylor University in Waco, Texas, says “Not so fast.” In the study, researchers examined the impact of remote work on employee well-being. Their findings suggest that a variety of factors can undermine or accent the employee benefits of working off-site. Accordingly, researchers developed new strategies to help managers provide remote-work opportunities that are valuable to the employee and the company. “Any organization, regardless of the extent to which people work remotely, needs to consider well-being of their employees as they implement more flexible working practices,” the researchers wrote. The study appears in the European Journal of Work and Organizational Psychology . In the review, a total of 403 working adults were surveyed for the two studies that made up the research, said lead author Sara Perry, Ph.D. Re

Today’s Popular Music is More Angry, Sad and Less Joyful

Today’s popular music is noticeably different from the popular songs of the 1960s and 1970s. Now a new study reveals that it’s not just the music itself that is different; today’s music consumers seem to prefer songs that express darker emotions in both lyric and tone. The findings, published in the Journal of Popular Music Studies , show that the expression of anger and sadness in popular music has increased gradually over time, while the expression of joy has declined. Using quantitative analytics, researchers from Lawrence Technological University in Michigan studied changes in popular music lyrics throughout the last seven decades, from the 1950s to 2016. Data scientists Kathleen Napier and Dr. Lior Shamir analyzed the lyrics of more than 6,000 songs found on the Billboard Hot 100, a list of the most popular songs of each year. In the past, songs were ranked primarily by record sales, radio broadcasting, and jukebox plays, but in more recent years, popularity is based on several

I Pretend that Fictional Characters Are Real & Talk to Myself as Them

I’ve always loved to play pretend. But now that I’m a teenager, instead of outgrowing it, it’s gotten worse. Now I’ve gotten to the point where it’s an obsession, and I spend more time with my imaginary friends then with real people. I pretend that my favorite characters from movies and TV shows are real, and I talk to myself, both as myself and the character. I have long discussions with myself. I also pretend that they are with me everywhere I go–to the supermarket, to my cousin’s house. I pretend that they’re with me, no matter what I do. Lately, I’ve also been doing something that’s hard to explain: I pretend to be two people (usually myself and my mother, or a cousin, or a made-up person) and have a pretend to have a conversation with them. I pretend that the fiction character is watching me and my mother/cousin/other. Usually, those scenarios involve either a verbal fight, or joking. I’m really concerned because I know this is abnormal and I’m not living a normal life. I’m worri
