Men at more risk for neurodevelopment disorder

Sex plays a major role in many neurological and psychiatric disorders like hypertension, diabetes and arthritis, a recent study has revealed.

According to findings appeared in the Journal of Nature Communications, depression and anxiety affect females more, while neurodevelopmental disorders, including autism spectrum disorders, early onset schizophrenia, and attention deficit hyperactivity, affect more males.

Males are also more sensitive to prenatal insults, such as gestational stress, maternal infection and drug exposure.

Neurodevelopmental disorders is a disorder of brain function that affects emotion, learning ability, self-control and memory and that unfolds as an individual develops and grows.

To understand the molecular underpinnings of this disparity, the researchers at the University of Maryland focused on a molecule that plays a key role in placental health.

The researchers focused on the links between stress and subsequent risk for neurodevelopmental disorders, including autism and schizophrenia.

Males are also more sensitive to prenatal insults, such as gestational stress, maternal infection and drug exposure.

Regular bedtime beneficial for heart and metabolic health among older adults

KATHMANDU — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But a new study on sleep patterns has suggested that a regular bedtime and wake time are just as important for heart and metabolic health among older adults too.

Researchers at Duke Health and the Duke Clinical Research Institute, in a study of 1,978 older adults, have found that people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.

The study  was published Sept 21 in the journal Scientific Reports.

“From our study, we can’t conclude that sleep irregularity results in health risks, or whether health conditions affect sleep,” said study’s lead author Jessica Lunsford-Avery.

“Perhaps all of these things are impacting each other.”

African-Americans had the most irregular sleep patterns compared to participants who were white, Chinese-American or Hispanic, the data showed.

Still, the data suggest tracking sleep regularity could help identify people at risk of disease, and where health disparities may impact specific groups.

Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.
