Geneticists are busy trying to find the specific gene variants involved, but because each one on its own only exerts a modest influence, this is challenging research requiring huge samples. A new study in Nature Genetics has made a significant contribution.
Just as genetics play a main role in your risk of developing many serious illnesses, your family history is one of the best indicators of your risk of developing mental disorders. Bipolar disorder and schizophrenia, for example, tend to run in families; there is no definitive way, however, of using genetics to determine whether an individual will develop mental illnesses. Not enough is known about the gene variations that contribute to them, and debate is still raging in the psychological community as to how genetics interact with other factors. To put it simply, the question of nature vs. nurture persists).
In its debut performance, a powerful new genetic engineering tool has revealed secrets of functionally distinct brain circuits for social fear and aggression in mice.
Researchers at the Washington University School of Medicine have linked mutations without a single gene to autism. The gene, also associated with a rare tumor syndrome, is found in patients with neurofibromatosis type 1 (NF1).
As severity of both increase, problems arise and they become more difficult to treat. But why substance involvement and psychiatric disorders often co-occur is not well understood.
It is principally hereditary factors that lie behind adults with ADHD often developing alcohol dependence and binge eating. This is the conclusion of a doctoral thesis from Linköping University.
You would think that after all these misbegotten studies scientists would have given up on their efforts to find a biological basis for crime. But no: in recent years there’s been a renewal of the science, most recently in the studies of an apparent ‘warrior gene’ that makes some men (it’s always men) inherently violent
Schizophrenia is not a single disease but rather is a group of distinct subtypes with varying symptoms based on a set of genes harboring novel or rare disruptive variants, a new study suggests.
Mental illnesses, like depression, are largely triggered by life events not genetics, and more funding should be allocated to find their true cause.
The risk of schizophrenia in children associated with younger and older maternal age appears to be partly explained by the genetic association between schizophrenia and age at first birth, according to an article published online by JAMA Psychiatry.
To completely discount inheritability of faulty genes when analyzing even diseases such as schizophrenia or bipolar disorder beggars belief.
Researchers showed that a gene called ‘DISC1,’ which is believed to play a role in these mental health disorders.
Researchers have identified a gene that increases the risk of schizophrenia, and they say they have a plausible theory as to how this gene may cause the devastating mental illness.
A landmark study, based on genetic analysis of nearly 65,000 people, has revealed that a person’s risk of schizophrenia is increased if they inherit specific variants in a gene related to “synaptic pruning” — the elimination of connections between neurons.
In an article recently published in Psychological Review, Joiner et al. argue that a tendency towards self-sacrifice among humans is adaptive in some situations. However, when individuals mistakenly view their own deaths as being worth more than their lives, results can be needlessly lethal.
Exposure to miniscule amounts of lead may contribute to ADHD symptoms in children who have a particular gene mutation, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
The Making of a Murderer: Expert Reveals the Psychology Behind Why People Commit Violent Crimes and Mass Shootings
Men are the perpetrators in a staggeringly high number of homicides, especially mass shootings – up to as many as 97 per cent. But what causes these typically young, male killers to want to commit such violent crimes?
New findings are enhancing understanding of how schizophrenia affects the workings of the brain, and open the way to new approaches for future drug therapies.
Rende, a professor at Brown University’s medical school, looks at which genes may play a role in psychological disorders common in youth, as well as which interventions seem promising. What stands out, however, is that Rende emphasizes, too, the limitations of using genomics. The field in itself is not, he warns, a panacea.
With so many digital distractions a mere mouse click away, procrastination is easier than ever. You want, nay need, to work on an important project, yet find yourself browsing Twitter, making coffee, checking email – basically anything other than doing what you should be doing.
Just because you can do something doesn’t mean you should do it. Many of us could drive a bicycle on a freeway, but it wouldn’t be a wise thing to do. Many of us could pay money for “brain games,” but it wouldn’t necessarily help our brains’ health.
A review by the New England Center for Investigative Reporting has found that virtually all the evidence that these psychiatric tests work is based on limited studies funded by the companies themselves or researchers they fund, including all five studies used to promote GeneSight on the company’s website.
A new twin study, published today in PNAS, of the genetic influences on face recognition ability, supports the idea that face recognition is a special skill that’s evolved quite separately from other aspects of human cognition.
A new study suggests that while a certain gene variant may predispose people to depression following a history of bad life events, such as childhood abuse, that same gene may also enhance happiness when bad life events are absent.
The more we’ve learned about specific connections between genomic variations and diseases, the more important genetic testing and counseling have become. But one area of medicine has lagged in providing this genetic counseling, with unsettling consequences — mental illness.
