The locus coeruleus LC , the origin of noradrenergic modulation of cognitive and behavioral function, may play an important role healthy ageing and in neurodegenerative conditions. Using structural equation modelling, we tested the pre-registered hypothesis that putatively noradrenergic NA -dependent functions would be more strongly associated with LC-CR in older versus younger adults. A unidimensional model within which LC-CR related to a single factor representing all cognitive and behavioral measures was a better fit with the data than the a priori two-factor model within which LC-CR related to separate NA-dependent and NA-independent factors. Our findings support the concept that age-related reduction of LC structural integrity is associated with impaired cognitive and behavioral function. The locus coeruleus LC is a small, elongated nucleus in the rostral pontine brainstem and is the major origin of noradrenergic NA neurons in the central nervous system.

Stress reduction through contact with nature is well established, but far less is known about the contribution of contact parameters — duration, frequency, and nature quality. This study describes the relationship between duration of a nature experience NE , and changes in two physiological biomarkers of stress — salivary cortisol and alpha-amylase. It is the first study to employ long-term, repeated-measure assessment and the first evaluation wherein study participants are free to choose the time of day, duration, and the place of a NE in response to personal preference and changing daily schedules.

During an 8-week study period, 36 urban dwellers were asked to have a NE, defined as spending time in an outdoor place that brings a sense of contact with nature, at least three times a week for a duration of 10 min or more. Their goal was compliance within the context of unpredictable opportunity for taking a nature pill.

Participants provided saliva samples before and after a NE at four points of real life by having control of the date, time of day (anytime from 1 h after rising The Loess smoothing function was applied to untransformed data.

Millions of readers rely on HelpGuide for free, evidence-based resources to understand and navigate mental health challenges. Please donate today to help us protect, support, and save lives. Coping with change is difficult, no matter how old you are. The particular challenge for older adults is the sheer number of changes and transitions that start to occur—including children moving away, the loss of parents, friends, and other loved ones, changes to or the end of your career, declining health, and even loss of independence.

But if that sense of loss is balanced with positive ingredients, you have a formula for staying healthy as you age. Healthy aging means continually reinventing yourself as you pass through landmark ages such as 60, 70, 80 and beyond. It means finding new things you enjoy, learning to adapt to change, staying physically and socially active, and feeling connected to your community and loved ones.

Unfortunately, for many of us, aging also brings anxiety and fear. How will I take care of myself late in life? What if I lose my spouse?

Many Americans today enjoy excellent oral health and are keeping their natural teeth throughout their lives. But this is not the case for everyone. Cavities are still the most prevalent chronic disease of childhood. Too many people mistakenly believe that they need to see a dentist only if they are in pain or think something is wrong, but they’re missing the bigger picture.

A dental visit means being examined by a doctor of oral health capable of diagnosing and treating conditions that can range from routine to extremely complex. The team approach to dentistry promotes continuity of care that is comprehensive, convenient, cost effective and efficient. Members of the team include dental assistants, lab technicians and dental hygienists.

Blood lead concentrations have decreased dramatically in U. However, too many children still live in housing with deteriorated lead-based paint and are at risk for lead exposure with resulting lead-associated cognitive impairment and behavioral problems [AAP ; ACCLPP ]. No matter how toxic, no chemical can harm a person child, adult, or both unless exposure occurs.

After a sufficient level of exposure dose to the chemical, biologic uptake, target organ contact, and biologic change can occur, all of which can lead to disease or other effects [ATSDR ; ATSDR ]. For a toxicant to cause disease, exposure must occur.

Previous studies of the association between parity and long-term cognitive changes have primarily focused on women and have shown conflicting results.

We investigated this association by analyzing data collected on , subjects from the UK Biobank. We found that in both females and males, having offspring was associated with a faster response time and fewer mistakes made in the visual memory task. Subjects with two or three children had the largest differences relative to those who were childless, with greater effects observed in men.

We found that in both sexes, subjects with two or three offspring had significantly reduced brain age compared to those without offspring, corroborating our cognitive function results.

Since respirators are not as consistently reliable as engineering and work practice controls, and may create additional problems, they are not the preferred method of reducing exposures below the occupational exposure levels. Accordingly, their use as a primary control is restricted to certain circumstances.

He struggled with mental illness and remained poor and virtually unknown throughout his life. Van Gogh was born exactly one year after his parents’ first son, also named Vincent, was stillborn. At a young age — with his name and birthdate already etched on his dead brother’s headstone — van Gogh was melancholy. Theo van Gogh would later play an important role in his older brother’s life as a confidant, supporter and art dealer.

At age 15, van Gogh’s family was struggling financially, and he was forced to leave school and go to work. There, he fell in love with English culture. He visited art galleries in his spare time, and also became a fan of the writings of Charles Dickens and George Eliot. He also fell in love with his landlady’s daughter, Eugenie Loyer. When she rejected his marriage proposal, van Gogh suffered a breakdown. He threw away all his books except for the Bible, and devoted his life to God.

He became angry with people at work, telling customers not to buy the “worthless art,” and was eventually fired.

Dating is a stage of romantic relationships in humans whereby two people meet socially with the aim of each assessing the other’s suitability as a prospective partner in an intimate relationship. It is a form of courtship , consisting of social activities done by the couple, either alone or with others.

While the term has several meanings, the most frequent usage refers to two people exploring whether they are romantically or sexually compatible by participating in dates with the other.

For more than 50 years, researchers have studied the nature of the between partners before and after the introduction of online dating.

Research on adult attachment is guided by the assumption that the same motivational system that gives rise to the close emotional bond between parents and their children is responsible for the bond that develops between adults in emotionally intimate relationships. The objective of this essay is to provide a brief overview of the history of adult attachment research, the key theoretical ideas, and a sampling of some of the research findings.

This essay has been written for people who are interested in learning more about research on adult attachment. The theory of attachment was originally developed by John Bowlby – , a British psychoanalyst who was attempting to understand the intense distress experienced by infants who had been separated from their parents. Bowlby observed that separated infants would go to extraordinary lengths e. At the time of Bowlby’s initial writings, psychoanalytic writers held that these expressions were manifestations of immature defense mechanisms that were operating to repress emotional pain, but Bowlby noted that such expressions are common to a wide variety of mammalian species, and speculated that these behaviors may serve an evolutionary function.

Executive function EF refers to a set of cognitive functions that support goal-directed behaviors. Recent findings have suggested that the frontoparietal network FPN subserves neural processes that are related to EF. However, the FPN structural and functional network properties that mediate age-related differences in EF components remain unclear.
