Hypothalaumus Connectivity Changes in Cluster Headaches
by William Yates, M.D. in Brain Posts
Cluster headaches are a relatively rare but serious pain disorder. Unlike the female-predominant migraine headache, cluster headaches occur predominantly in men. These headaches tend to be acute in onset and affect only one side of the head.The term cluster describes the typical chronological pattern of these headaches. The tend to occur regularly for days or weeks and are then separated by periods of remission lasting months or years.Attacks typically last between 15 minutes a........ Read more »

EEG Differentiates Adjustment Disorder From Depression
by William Yates, M.D. in Brain Posts
A key element in discovering valid mental disorder categories is to differentiate a mental disorder from other valid mental disorder categories.Biological markers for mental disorders have been slow to develop. Functional brain imaging techniques and other research tools are evolving to help in the important task of improving the validity of clinical neuroscience disorders.Adjustment disorder is a relatively common condition that has lagged in research attention. Adjustment disorder ........ Read more »

What’s The Point of Bingeing and Purging? And Why Can’t You Just Stop?
by Tetyana in Science of Eating Disorders
I defended my MSc degree on Tuesday and I’m not going to lie: I was pretty symptomatic with bulimia in the days prior to my defence. As I was explaining to my boyfriend, the anxiety-reducing effects of purging are so powerful, and the compulsion to binge and purge (when I’m stressed/anxious/”not okay”) is so strong that it is much easier to do it, get it over with, and continue working (in a much calmer state).
I’ve mentioned before, for me, purging is very anxiety-........ Read more »

Is having many cats an early sign of animal hoarding?
by CAPB in Companion Animal Psychology Blog
In January of this year, 99 live cats and 67 dead ones were removed from a woman’s home near Albany, New York. The cats were living in crates surrounded by faeces, and the woman was subsequently charged with animal cruelty. If situations like this could be predicted, psychological help at an early stage might prevent animals from being harmed. A study published this month by Ramos et al in Brazil investigates whether or not the early stages of cat hoarding can be identified. Animal h........ Read more »

Blast-related Traumatic Brain Injury and fMRI
by William Yates, M.D. in Brain Posts
Blast-related traumatic brain injury (TBI) is an important research topic. Over 100,000 armed services personnel experienced a significant traumatic brain event in the last decade. A majority of these were explosion or blast-related in nature.However, standard brain imaging techniques (computed tomographay, structural MRI) typically fail to demonstrate changes following blast TBI. New imaging strategies are needed to assess severity and progression.Graner and colleagues from Wa........ Read more »

Football and the Blood Brain Barrier
by William Yates, M.D. in Brain Posts
A variety of research tools are being utilized to study the effect of trauma on the brain. In a previous post, I summarized some of the research using diffusion brain imaging or DTI.A recent study looked at the function of the blood-brain barrier (BBB) in a group of football players. The BBB is an important brain protective mechanism. A variety of blood proteins and other compounds have the potential to cause inflammation and other damage to neurons and other brain cells.Marchi........ Read more »

ECT Reverses Depression Brain Connectivity Deficit
by William Yates, M.D. in Brain Posts
Electroconvulsive treatment (ECT) remains one of the most effective treatments for major depressive disorder (MDD).The mechanism of action for ECT in MDD is unclear. Research targeting brain changes in ECT is an important pathway to understanding the mechanism of action for ECT.Patients with MDD show disruptions in brain functional connectivity as measures by functional magnetic resonance imaging (fMRI). The connectivity abnormalities in MDD have included changes in limbic, cortical........ Read more »

That’s a really great question. Whether we watch, read, or listen to the news, I’m sure we have all had the feeling of being sick about it; be it the story itself or how it is presented. A huge proportion of our news seems to be negatively biased – but why? The answer has, in [...]... Read more »

Personality Traits after Recovery from Eating Disorders: Do Anorexia and Bulimia Patients Differ?
by Tetyana in Science of Eating Disorders
When we think about eating disorders, we tend to think about eating disorder subtypes: anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder. A lot of previous work has shown that individuals with AN and BN tend to be anxious, depressed, perfectionistic, and harm-avoidant. Patients with AN also tend to score low on novelty-seeking, impulsivity, and self-directedness, whereas patients with BN score high on novelty-seeking and impulsivity. More recently, however, some researchers ........ Read more »

Donepezil Improves Dementia With Lewy Bodies
by William Yates, M.D. in Brain Posts
Dementia with Lewy bodies (DLB) is a type of dementia less common than Alzheimer's disease. However, Lewy bodies (brain neuron deposits of the proteins alpha-synuclean and ubiquitin) are found in up to 10 to 15% of individuals dying of dementia.DLB is known to deplete brain acetylcholine and dopamine neurotransmitter levels in the brain. This leads to a clinical syndrome characterized by both cognitive decline and motor symptoms similar to Parkinson's disease.DLB may be difficult to ........ Read more »

Is Anorexia Nervosa An Anxiety Disorder?
by Tetyana in Science of Eating Disorders
Anxiety disorders (ADs) are common among patients with eating disorders. In one study of female inpatients, around 50-65% had a comorbid anxiety disorder (see my post here). Anxiety disorders in patients with anorexia nervosa (AN) typically begin before the eating disorder and often persist after weight restoration and recovery (Bulik et al., 1997; Casper, 1990). Moreover, previous twin studies have suggested that there’s a “correlation between eating disorders and certain anxiety an........ Read more »

Over-Exercise is Associated With Suicidality in Individuals with Disordered Eating

Last week, I blogged about a study that examined personality traits and clinical variables associated with excessive exercise in eating disorder patients. In that study, 2 out of 5 participants engaged in excessive exercise Today, I’m going to discuss a study that suggests over-exercise in disordered eating patients is associated with suicide behaviour.
Suicide rates in eating disorder patients are high. One meta-analysis suggested that out of all eating disorder related deaths, 1 in ........ Read more »

Oxytocin and Human Attachment
by William Yates, M.D. in Brain Posts
In a previous post, I summarized a recent review on the neuroscience of human attachment. This review highlighted research related to the human bonding and social interactions. Attachment ability shows significant variability in humans with insecure attachment styles contributing to risk for some mental disorders. The neuroanatomical framework for social processing is being investigated with brain imaging techniques.Hormonal factors including the role of oxytoc........ Read more »
