barin volume

The scientists used MRI data mapped onto an existing atlas of the mouse brain to compare the effects of drinking ethanol and water on brain volume overall and region-by-region in mice with and without dopamine D2 receptors. Alcohol-drinking mice that lacked dopamine receptors had lower overall brain volume and reduced volume in the cerebral cortex (blue) and thalamus (purple) compared with D2 receptor-deficient mice drinking water. Alcohol-drinking mice with dopamine receptors did not show these deficits in response to drinking alcohol, suggesting that dopamine receptors may be protective against the brain atrophy associated with chronic drinking.

Brain scans of two strains of mice imbibing significant quantities of alcohol reveal serious shrinkage in some brain regions — but only in mice lacking a particular type of receptor for dopamine, the brain’s “reward” chemical – but only in mice lacking a particular type of receptor for dopamine, the brain’s “reward” chemical. The study, conducted at the U.S. Department of Energy’s Brookhaven National Laboratory and published in the May 2012 issue of Alcoholism: Clinical and Experimental Research, now online, provides new evidence that these dopamine receptors, known as DRD2, may play a protective role against alcohol-induced brain damage.

New research from Perth’s Telethon Institute for Child Health Research has found that children of mums who had low levels of Vitamin D during pregnancy are twice as likely to have language difficulties.

The research, published in the latest edition of the international journal Pediatrics, is the largest study of its kind into the link between a mother’s vitamin D levels and the effect on her child’s speech and behavioural development.

The study looked at Vitamin D concentrations during the pregnancies of more than 740 women, with follow up investigations of their child’s development and behaviour at regular periods up to 17 years of age. [continue reading…]

Is the Spirit of Childhood at Risk?

family-funThe results of a new global report released today by the OREO brand and Ipsos Public Affairs indicate that from China to Poland and Portugal to Venezuela, the spirit of childhood – that is, the chance for children and adults alike to enjoy simple, carefree moments – may be destined for the endangered species list. The report reveals that the vast majority of parents surveyed believe today’s kids are growing up quicker than previous generations. In fact, seven out of 10 parents worldwide say their children should have more time to ‘just be kids.’

The idea that the spirit of childhood is on the decline is true not only for kids, but also adults. Parents everywhere yearn for the type of lighthearted enjoyment they had when they were kids. In fact, a majority of parents worldwide (59%) say they don’t have fun on a daily basis and 54 percent say they rarely experience the feelings of delight they did when they were children.

The “Global Spirit of Childhood Report, conducted by Ipsos Public Affairs on behalf of OREO, measured the spirit of childhood around the world in an effort to understand if people, both young and old, take the time to experience the simple joys of being a kid.

“As we regularly talk with consumers worldwide, we consistently hear about the importance of experiencing the carefree feelings of childhood at any age,” said Sheeba Philip, Global Brand Director for OREO. “We believe this sentiment is more important now than ever before, so we conducted this research to learn more about the spirit of childhood worldwide.” [continue reading…]

Dignity counts when caring for older people

Older people feel that their health problems pose a challenge to their sense of independence, dignity and identity and sometimes the health care they are given makes things worse.

According to research funded by UK Research Councils’ New Dynamics of Ageing programme (NDA), healthcare providers must avoid taking a ‘blanket view’ of how to help older people cope with the ageing process.

The study carried out by Dr Liz Lloyd and her colleagues found that people were often surprised by the impact that illness and growing old had on their lives. Their sense of ‘self’ was affected by the limitations imposed by their age and illnesses. “Growing old and coming to terms with illnesses is complex and demanding at times – physically, mentally and emotionally,” Dr Lloyd said. “When health goes, it can come as quite a shock.”

The research shows that older people work hard at maintaining their health and independence, while coming to terms with becoming dependent on others. The participants’ views show how, with the struggle to maintain day-to-day activities, their dignity can quickly and easily be lost. One participant, Mary, told researchers:

“Inside I feel as though I ought to be able to do things. But I’m not and it’s hard to accept.”

While some were positive about making changes, others found it harder to adjust their day-to-day routines. All participants made great efforts to find new activities or adapt old ones. For example several learnt to use computers and others took art classes at day centres. All tried to maintain their health in a variety of ways.

Dr Lloyd believes the research shows there are significant differences in the way that people define dignity and independence, and that these are influenced by their relationships, abilities and  life experiences. She states, ”

You can’t impose a blanket view of what dignified care is. Of course, there are certain standards that should apply in all circumstances but enhancing dignity needs a lot more than guaranteeing minimum standards.”

“In old age when your health fails, it affects your sense of self. Understanding that from an older person’s perspective is crucially important. Care and support can enhance dignity or it can worsen the loss of it if not given in the right way.  Good support is essential in terms of how people make the adjustments they need to make.”

Dr Lloyd highlights that the relationship between dignity, identity and independence is complex. “Loss of independence involves a change in your identity and is a challenge to your dignity,” she states. “It is through the support of others that individuals are able to rebuild their sense of identity in their changed circumstances.”

Support and care need to be responsive to what people are going through and to see things from the perspective of the person on the receiving end of care. “Older people are going through enormous changes and the people who are helping them need to be aware of these.”
