Social Isolation Transforms the Brain

In mice.

Confirming and extending previous observations, the researchers showed that prolonged social isolation leads to a broad array of behavioral changes in mice. These include increased aggressiveness towards unfamiliar mice, persistent fear, and hypersensitivity to threatening stimuli. For example, when encountering a threatening stimulus, mice that have been socially isolated remain frozen in place long after the threat has passed, whereas normal mice stop freezing soon after the threat is removed. These effects are seen when mice are subjected to two weeks of social isolation, but not to short-term social isolation — 24 hours — suggesting that the observed changes in aggression and fear responses require chronic isolation.

Though the work was done in mice, it has potential implications for understanding how chronic stress affects humans.

Get out of the house.  Socialize with friends and family.  Leave the cell phone at home.

Social media is not social.  It’s a serious public health problem for the brainwashed masses with addictive behaviors.

When Teens Cyberbully Themselves (another reason to take the phone away)

Recent research and clinical psychologists now suggest that some adolescents are engaging in a newer form of self-aggression — digital self-harm. They’re anonymously posting mean and derogatory comments about themselves on social media.

Digital self-harm.

Parents – take the phone away.

Very interesting article.  HT to naked capitalism.

Put The Phone Down…

And keep your hands where I can see them.

Use of computer games was found to be negatively related to all personality and mental health variables: self-esteem, extraversion, narcissism, life satisfaction, social support and resilience.

The use of platforms that focus more on written interaction (Twitter, Tumblr) was linked to depression, anxiety, and stress symptoms.

In contrast, Instagram use, which focuses more on photo-sharing, was linked to positive mental health variables.

ADHD Prescriptions Skyrocket Among Young Women

The percentage of women who filled a prescription for an ADHD medication rose from 0.9% in 2003 to 4.0% in 2015 ― an increase of 344%, the researchers report.

ADHD prescriptions increased for all subgroups of female patients aged 15 years to 44 years (analyzed in 5-year increments), and in all geographic regions of the country. The largest increase in ADHD prescriptions occurred among women aged 25 to 29 years (700% increase), followed by women aged 30 to 34 (560% increase).

Low Folate, Vitamin D Implicated in First-Episode Psychosis

 

Nutritional deficiencies, especially deficiencies in folate and vitamin D, are associated with first-episode psychosis (FEP), new research suggests.

Australian researchers found significantly lower levels of folate and vitamin D in patients with FEP, compared to healthy control persons. Limited evidence also suggested that serum levels of vitamin C were reduced in people with FEP.
