Antidepressants Modulate Memory in the Healthy Brain
by William Yates, M.D. in Brain Posts
The mechanism of antidepressant drug response is not well understood.One theory posits antidepressant effects are only seen in those with clinical depression leaving the healthy brain unchanged.In a previous post, I outlined a study demonstrating effects of antidepressants on brain connectivity measures in the healthy brain.A recent fMRI study extends our understanding of the potential mechanisms for antidepressant drugs.CT Cerqueira and colleagues from Brazil studied the effects of the antidepr........

Cannabis-induced Paranoia: Cognitive Mechanisms
by William Yates, M.D. in Brain Posts
Some individuals appear vulnerable to paranoia induced by exposure to tetrahydrocannabinol (THC) in cannabis.The mechanism for this effect is poorly understood.Daniel Freeman from University of Oxford along with colleagues in England and Switzerland recently conducted an interventional research study on this issue.In this study, 121 subjects were recruited to receive injections of THC in a laboratory setting.These subjects were required to have taken cannabis at least once before participation i........

Unpacking Recovery Part 5: Clinical Recovery without a Clinic?
by Andrea in Science of Eating Disorders
It can be somewhat controversial to suggest that untreated recovery from eating disorders is possible. Certainly, people have varied opinions about whether someone can enact the difficult behavioral and attitudinal changes necessary to recover without the help of (at the very least) a therapist and a dietitian. Nonetheless, we still hear stories about individuals who consider themselves recovered without having sought out external sources of professional support.

Unpacking Recovery Part 4: Are We All on the Same Page?
by Andrea in Science of Eating Disorders
Another issue in defining and understanding recovery is that patients and clinicians may have different opinions about what recovery looks like and how to get there. Certainly, there is a body of literature from the critical feminist tradition in particular that explores how at times, patients can “follow the rules” of treatment systems to achieve a semblance of “recovery,” from a weight restoration and nutrition stabilization perspective, but feels nothing like a full and happy li........

Gambler Sub-types: Three Distinct Profiles
by William Yates, M.D. in Brain Posts
One method to advance understanding of a disorder is to use statistical modeling for sub-type or class analysis.Lia Nower and colleagues recently published the results of such an analysis from the large general population data-set known as the U.S. National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).In this sample, 851 adults 18 years and older were identified with disordered gambling.This group then underwent a type of latent class statistical analysis known as the Pathways........

Diagnostic Profile in Pathological Gamblers
by William Yates, M.D. in Brain Posts
Behavioral disorders like pathological gambling (PG) rarely occur alone as a single uncomplicated disorder.In a previous post, I noted the overlap of PG with personality disorder, anxiety disorder, depression, bipolar disorder and substance abuse.A recent study from Germany adds to our knowledge of the general diagnostic profile in the PG population.Erbas and Buchner reviewed German national data sources and other German studies to come up with a series of findings:Twelve month prevalence rates ........

Narcotics Anonymous for military veterans
by DJMac in Recovery Review
A few years back in a city far, far away, I asked a consultant addiction psychiatrist why he did not refer any of his patients to NA. “There’s not a shred of evidence that it works,” he said. Even then he was misinformed, but I’ve thought many times since then about how his patients were [...]

Unpacking Recovery Part 3: Can Patients Imagine Recovery?
by Andrea in Science of Eating Disorders
Today I have the distinct pleasure of writing about one of my favourite articles about eating disorder recovery by Malson et al. (2011) exploring how inpatients talk about eating disorder recovery. I have personally found this article to be very helpful in understanding some of the difficulties of understanding and achieving recovery in our social context.
As Malson and colleagues explain (and as we’ve established), eating disorder recovery is elusive. Often, poor prognosis is described ........ Read more »

Using Animal Research to Justify Eating Disorder Treatment Practices: Are We Going Too Far? (On Eating Junk Food in Treatment – Part II)

Guidelines for Treatment of Problem Gambling
by William Yates, M.D. in Brain Posts
Despite the prevalence and impact of problem gambling, few summaries or guidelines address treatment.Searching the guideline.gov website shows no recent additions to the guideline literature.A guideline was published by the Singapore Ministry of Health in 2011. This guideline is still relevant and highlights some of the key elements of a problem gambling treatment program.I will summarize some of these key elements from this source titled: "Management of gambling disorders".

In Defense of Eating Junk Food in Eating Disorder Treatment
by Shirley in Science of Eating Disorders
Should eating disorder patients be introduced to “junk food” or “hyper-palatable” foods during treatment? A few days ago, I stumbled across a blog post where Dr. Julie O’Toole, Founder and Director of the Kartini Clinic for Disordered Eating, argues against introducing “junk food” during ED treatment. The crux of the argument is that “hyperpalatable foods”—e.g., chips and Cheetos—are not real food and should never be forced or encouraged for anyone, regard........ Read more »

Dying To Make Us Laugh
by Mark E. Lasbury in The 'Scope
Robin William’s suicide was a tragic, but all too familiar happening amongst humorists of this period. New research is showing that comedians, performers in the arts, and even people with better senses of humor are prone to more health problems as adults. Depression , cardiovascular, pulmonary and stress related problem are not uncommon in comedians, and even children and adults that have better sense of humor are susceptible to obesity and cardiovascular disease.

Clinical Drug Trials for Pathological Gambling
by William Yates, M.D. in Brain Posts
Several drug classes hold promise for reduction in pathological gambling behavior.However, there are very few published randomized and controlled clinical drug trials in gambling subjects.Searching clinical trials and gambling on PubMed yields only one small open-label proof of concept trial for the drug tolcapone within the last year.This study found evidence that this COMT inhibitor drug reduced gambling symptoms and was accompanied by fronto-parietal activation on fMRI imaging.However, on sea........

Does AA work for young people?

Unpacking Eating Disorder Recovery Part 1: The Recovery Model
by Andrea in Science of Eating Disorders
What does eating disorder recovery really look like? When you say the word “recovery,” differences of opinion loom large. The lack of definitional clarity around the concept of recovery came up many times at ICED, and continues to surface in discussions among researchers, clinicians, and individuals with eating disorders themselves. We’ve looked at recovery on the blog before (for example, Gina looked at how patients define recovery here; Tetyana surveyed readers about th........ Read more »

Serious Restrictive Eating Disorders Occur at Any Weight
by Tetyana in Science of Eating Disorders
Although the words “anorexia nervosa” typically conjure up images of emaciated bodies, eating disorders characterized by dietary restriction or weight loss can — and do — occur at any weight. However, precisely because anorexia nervosa is associated with underweight, doctors are less likely to identify eating disorders among individuals who are in the so-called “normal” or above normal weight range, even if they have........

Twitter Psychosis as a Cultural Artifact

Can Twitter really “cause” psychotic symptoms in predisposed individuals?
