This is the opening of the transcript for the video:

Narrator: It's 1:00 a.m. You should be sleeping but you're glued to your smartphone, catching up on the latest news, Facebook updates and tweets. It turns out that the smartphones and tablets that keep you connected and organized may also be keeping you awake.

See, our eyes perceive light in a range of wavelengths. Different wavelengths produce different color sensations and those sensations help tune your internal clock. Here's sleep researcher Brian Zoltowski.

Professor Brian Zoltowski: One of the best biological cues we have to what time of day it is, is light and it turns out that blue light, in particular, is very effective for basically predicting when morning is.

Narrator: And guess what puts out a ton of blue light?

Professor Zoltowski: Your iPad, your phone, your computer, emit large quantities of blue light.




Common Hypertension Treatment May Reduce PTSD Symptoms

Recently, however, investigators at Emory University observed that individuals diagnosed with PTSD, and who happened to also be treated with ARBs or ACE inhibitors, exhibited fewer PTSD-like symptoms.

This led the researchers to investigate the underlying mechanisms using an animal model of PTSD in order to expand upon this clinical finding.

Dr. Paul Marvar, first author and Assistant Professor at The George Washington University, explains their findings, "Our current preclinical results show that the ARB losartan, given acutely or chronically to mice, enhances the extinction of fear memory, a process that is disrupted in individuals with PTSD. Overall these data provide further support that this class of medications may have beneficial effects on fear memory in PTSD patients."

Fear extinction is a process by which a memory associated with fear is gradually 'overwritten' in the brain by a new memory with no such association.


Ketamine shows 'game-changing' effect on suicide prevention

Lead author Colleen Loo is a professor at the University of New South Wales in Sydney, where she specializes in psychiatry and neurosciences. She describes the finding as a "game-changer in treating depression," and says:

"The real advantage here is that the effect is almost instantaneous and that it appears to work on the majority of patients."

Current drugs for depression can take up to 8 weeks to reach full effect. Also, it is not easy to match the right drug to the right patient, which has to be done by trial and error.

"This could be of real benefit if a patient is suicidal, as it could help yank them out of that really dark place," says Prof. Loo, who also explains how ketamine works:

"Ketamine powerfully reverses structural changes in the brain that occur when someone is depressed. In a sense, the treatment is repairing or reversing those changes."


Nasal spray for heroin antidote under development

 Lexington, Ky., doctor has struck a critical agreement to get a life-saving product in the hands of emergency room workers and paramedics across the country as they battle the nation's heroin epidemic.

Dr. Daniel Wermeling, a professor of pharmacy at the University of Kentucky, has signed an agreement with Reckitt Benckiser Pharmaceuticals Inc. to accelerate production and marketing of intranasal naloxone, a drug designed to treat heroin and opioid overdose. 

Nationally, more than 16,500 Americans die each year from prescription opioids, which include prescription painkillers such as hydrocodone, methadone, oxycodone and oxymorphone. The drugs are chemical cousins to heroin, and the spike in their abuse has fueled the recent heroin addiction crisis.

Estimates on the number of U.S. heroin addicts range from 300,000 to 500,000, up about 75 percent from five years ago, according to the National Institute on Drug Addiction.

In the past 10 years, heroin and related opioid pain pills have killed more than 125,000 Americans, according to Centers for Disease Control and Prevention data.



Naloxegol may be the answer to opioid-induced constipation

Pain medicines often lead to constipation for patients seeking long-term pain relief, but an investigational once-daily drug may help, according to study led by the University of Michigan Health System.

Globally, approximately 28 million to 35 million, or nearly half, of patients taking opioids for long-term pain develop constipation. Laxatives provide sub-optimal relief.

The results of two pivotal Phase 3 studies - KODIAC-4 and KODIAC-5 of naloxegol, an investigational treatment for opioid-induced constipation (OIC) - were published online first in theNew England Journal of Medicine.

A 25 mg dose of the investigational drug naloxegol safely increased bowel movements among opioid-induced constipation sufferers, compared to a placebo, and the effects were maintained over a 12-week treatment period.


Podcast: Mental Illness and Parenting

http://goo.gl/YIucQs

Wessler’s reporting showed that in dozens of states, courts have the power to sever parents’ connection to a child if authorities conclude that a mental illness might render them incapable of proper care – even if there’s no evidence of actual harm or neglect.

To be clear, he says, there are parents whom mental illness renders unable to care for their children. But there are many others harmed by laws based, as Umansky points out, on "a very different conception than the latest understanding of what mental illness is and the ability to moderate it."


Allowing patients to choose their PTSD treatment is cost-effective

This shouldn't be all that surprising since recreating your personal autonomy is a necessary step in PTSD recovery.....

A cost-analysis of post-traumatic stress disorder treatments shows that letting patients choose their course of treatment - either psychotherapy or medication - is less expensive than assigning a treatment and provides a higher quality of life for patients.

In a recent study, published in the Journal of Clinical Psychiatry, PTSD patients allowed to choose between therapies ended up costing about $1,622 less on average per patient per year compared with patients who were assigned treatment. Among patients not given a choice, treatment with prolonged exposure psychotherapy cost less on than sertraline.


One Breakdown Can Mean Losing Your Kid Forever

State governments are permanently taking hundreds of children from their parents—under a bizarre theory that they might, in the future, be too mentally ill to care for the young.

The question in Mindi’s case is not about what authorities did when she plunged into a mental health crisis—nearly everyone involved in the case, including Mindi’s own attorneys, agrees it was likely appropriate to remove her baby that day. Instead, the issue is whether a mental health diagnosis itself, in the absence of any harm, should be enough to keep Mindi from ever getting her daughter back.

Under a concept sometimes called “predictive neglect,” Missouri and about 30 other states allow courts to terminate a parent’s connection to a child if authorities conclude a mother or father has a mental illness that renders them incapable of safely raising the child. Officials usually must present evidence that the illness poses a threat. Most cases involve significant mental illness, not run-of-the-mill depression or anxiety. Yet there need be no evidence of actual harm or neglect, just a conclusion that there is a risk of it.


People with diverse compulsion disorders have similar decision and brain patterns

http://goo.gl/LBdQ33

A new study finds people with compulsion disorders such as substance abuse, binge eating and obsessive compulsive disorder have similar patterns of decision making and brain structures.

Reporting their findings in the journal Molecular Psychiatry, the researchers explain how they discovered people affected by disorders of compulsivity tend towards automatic habitual choices than goal-directed behaviors. Plus, they also have lower grey matter volumes - which indicates fewer brain cells - in brain regions that help track goals and rewards.

Every day we make decisions, and these tend to be of two types: habitual or goal-oriented. A good example of habitual decision-making is when we are on "autopilot" as we drive the familiar route home from work. This can slip into goal-oriented behavior if we are diverted onto a less familiar road - the goal being to get back to the familiar route


Which Nutrients Help Treat Restless Leg Syndrome?

Antipsychotic medications are notorious for producing this side effect, called akathisia. I ran across it as a complaint (for some the worst single side effect of the medication) in the 70's. It really irritates me when people make fun of it......

As our own House Call Doctor explains, the causes are poorly understood - and various.  RLS sometimes accompanies other neurological diseases. It can also be exacerbated by certain prescription medications or nutrient deficiencies. It also simply runs in some families, with no obvious cause. (If you do struggle with RLS, take heart in the knowledge that it also sometimes disappears as mysteriously as it starts!). 

Stretching before bed can sometimes reduce the symptoms and Get-Fit Guy has some great stretching routines that target the legs and calf muscles. If your RLS is really interfering with your sleep and ability to function, your doctor may be able to prescribe medication that will help.  

But what about nutrition? Are there foods or supplements that can help with RLS?
