Diabetes Drug for Addiction Treatment
A relatively new class of drugs, glucagon-like peptide-1 (GLP-1) receptor agonists, have had much success in the treatment of type 2 diabetes. Now, these drugs may offer support in the treatment of addiction and drug abuse.
A new study, published in Translational Psychiatry, reports that GLP-1 receptors may be a target for treating drug abuse. The study was conducted in mice, but it calls attention to previous reports with similar findings.
Dopamine is essential to reward pathways that influence drug abuse and addiction. Endocannabinoids and arachidonic acid, which are also naturally present in the brain, affect the function of dopamine transporters. Activation of GLP-1 receptors reduces arachidonic acid in areas of the brain that are associated with reward; dopamine levels, in turn, reduce. In the current study, the long-lasting GLP-1 receptor agonist, exenatide, abolished cocaine-induced increases in dopamine levels.
GLP-1 is normally found in the gut and influences satiety signaling. In part, GLP-1 agonists, which mimic the activity of naturally-occurring GLP-1, regulate glucose homeostasis in type 2 diabetes by promoting a feeling of fullness. These drugs have been shown to aid in weight loss in patients with type 2 diabetes. These effects might also be due to the reduction in the rewarding effects of food, owing to GLP-1 action in regulating dopamine transporter activity and reducing reward related to food intake.
Both illicit drugs and palatable foods activate reward pathways in the brain. Therefore, pharmacologic modulation of these central nervous system circuits holds promise for reducing unwanted or abusive behaviors. The role of naturally occurring GLP-1 in affecting reward is unknown. The beneficial effects of GLP-1 agonist activity are now believed to extend not just to food, but alcohol and to psychostimulants, such as cocaine and amphetamine.
Several recent studies have highlighted the mechanism by which GLP-1 agonists influence reward-inducing behaviors in the central nervous system. While the place in therapy is not clearly defined, these findings could expand the therapeutic potential of this entire class of drugs.

“I’ll Do It Later” – Brain Connectivity Predicts Procrastination
Procrastination — we are all guilty of it. Irrationally delaying a task in day-to-day life can have minor effects, such as lost sleep from staying up late to meet a deadline, but it can also be detrimental. From a health perspective, waiting to go to the doctor until an illness becomes severe could be fatal. In the financial domain, procrastinating on taxes costs people hundreds of dollars per year in overpayments, and failing to start saving early for retirement can end up costing thousands of dollars. So why do we procrastinate, even though we know it is bad for us? There is a common perception that procrastination is associated with laziness or lack of motivation, but a recent fMRI study suggests something else.
A recent study published in Personality and Individual Differences by Wu and colleagues provides some insight into the neural underpinnings of procrastination by looking at a specific type of brain connectivity, resting state functional connectivity (rsFC), and investigating how this relates to individual levels of procrastination. This approach looks at how different regions of the brain are functionally connected, as opposed to anatomically (structurally) connected. When the brain is at “rest”, there is still some activity going on; it is always spontaneously firing at low-frequency fluctuations. Recent research has shown that there are distinct brain networks that fire together at rest, and these patterns have been linked to variations in cognitive abilities and behaviors.
The researchers hypothesized that procrastination is a result of failure in self-regulation, and thus brain regions involving impulsivity control and self-monitoring may have less functional connectivity in individuals who procrastinate more. They used measures of trait procrastination and self-control to assess procrastination tendencies and collected resting state fMRI data during which participants were instructed to lie quietly in the scanner, close their eyes, and let their mind wander for about 6 minutes. After careful analysis, Wu and colleagues were able to confirm that the functional connectivity between the hypothesized brain regions were indeed related to procrastination behavior. The circuit between the ventromedial prefrontal cortex, an area associated with value comparison, and the dorsolateral prefrontal cortex, a region involved in the control of behavior, was found to have reduced connectivity in high procrastinators. Similarly, the connectivity between the dorsal anterior cingulate cortex, involved in cognitive control, and the caudate, a reward processing area of the brain, was also reduced in severe procrastinators. Finally, the researchers evaluated connectivity within the ventrolateral prefrontal cortex, an area responsible for behavioral inhibition, and found that this was reduced in heavy procrastinators as well.
When they put everything together, as they expected, the behavioral measure of self-control was the best predictor of procrastination tendencies, but the neural functional connectivity was actually able to add significant additional predictive power on top of what self-control could predict by itself. This suggests that there is something unique about the neural connectivity that is able to predict procrastination beyond the self- control that is measured in the lab. The reduced functional connectivity in high procrastinators observed in regions of their brains suggest that procrastination is related to other factors linked to self-control, such as impulse control inability and optimal weighting of value options, something that has only been speculated by researchers before.
So, how does this information help researchers figure out ways to help people reduce procrastination? Identifying that procrastination is associated with a lack of self-control and impulsivity provides a good starting point for interventions that may reduce that behavior. A review by Piers Steel at University of Calgary suggests that procrastination might be reduced by increasing one’s confidence about completing a task, reducing distractions, fostering automaticity by creating habits, and setting daily goals. There has also been a recent interest in internet-based cognitive behavioral therapy. Rozental and colleagues at Stockholm University created an online based 8-week treatment program with different modules designed to reduce procrastination, with topics such as goal-setting, time management, and motivation. In a study of 150 participants who all scored extremely high (top 25%) on an index of procrastination behaviors, they found that internet-based cognitive behavior therapy was able to substantially improve self-report difficulties with procrastination in participants who completed the modules in comparison to control participants who did not complete the treatment, demonstrating that online training can indeed be effective for even the worst procrastinators.
One thing is for sure: the recognition of procrastination as a cognitive deficit is increasing. All of this work provides a promising start for awareness and treatments for even the most severe procrastinators.

Best and Worst of Neuroscience and Neurology – August 2016
This article summarizes some interesting publications that came out in August. As usual, there were many interesting developments, both in fundamental neuroscience and neurology, and in practical aspects of dealing with and treating brain-related diseases and disorders.
On August 20, the scientific community marked the birthday of Roger Sperry. Prof. Sperry received the 1981 Nobel Prize for Medicine and Physiology for his works on “split-brain” patients. In these patients, the corpus callosum connecting two brain hemispheres is severed. The works of Roger Sperry helped to establish that our two brain hemispheres do have different functions and often work independently.

Brain maintains representation of amputated hand decades later
It was traditionally assumed that after amputation of a hand or a finger the part of the brain representing it becomes “overwritten” due to the absence of input signals. New data demonstrate that this view is not correct and brain retains the picture of missing limb even several decade later. The findings might prove useful in creating neuroprosthetics – artificial limbs controlled directly by brain signals.
New blood test predicts the likelihood of developing Alzheimer’s disease in the future
Although early Alzheimer’s disease often manifests itself as a mild memory impairment, only some of patients with memory impairment will eventually develop this condition. New blood test developed by British scientists allows to predict the likelihood of developing the Alzheimer’s in the next few years in patients with mild memory problems. The test would help to identify vulnerable patients and advise them early on the course of action to prevent or delay the disease progression.
Parkinson’s disease spreads via intercellular nanotubes
Like most other neurodegenerative diseases, Parkinson’s disease is linked to formation and spread of protein aggregates, alpha-synuclein in the case of this condition. However, not much is known about the mechanisms responsible for the transfer of protein aggregates between the neural cells in brain. This month, researchers reported that alpha-synuclein aggregates can migrate from one cell to another along tunnelling nanotubes. The findings represent a serious breakthrough in understanding Parkinson’s disease and point to some new potentially useful therapeutic targets.
Lead causes oxidative stress in neural stem cells
Environmental exposure to lead is known to cause neurodevelopmental problems, particularly at early stages of life. The molecular mechanisms behind this effect remained unclear, however. Now scientists have found that lead induces oxidative stress in neural stem cells. Specifically, proteins SPP1 and NRF2 were found to be involved in this process. Both proteins are involved in cognitive development.
Genetic reprogramming can convert connective tissue cells into neurons
Genetic reprogramming of mature cells to create pluripotent stem cells was discovered 10 years ago. A number of improved technics for cellular reprogramming was invented since then. A novel revolutionary technique called CRISPR was recently used to convert the cells of connective tissue into neurons. The discovery may pave the way to model neurological disorders and develop cell therapy.
THE WORST
Stopping exercise at older age leads to decreased cerebral blood flow
The fact that fitness level drops quite quickly after stopping exercise is well known, but the changes in brain caused by termination of the regular exercise routine are not well studied. In a new research, scientists asked well trained senior athletes aged 50-80 years to stop exercising for 10 days, and then studied their cerebral blood flow. It turned out that all athletes experienced significantly decreased level of resting blood flow in a number of key areas of brain. Importantly, the blood flow was decreased in hippocampus, a part of brain crucial for learning and memory. Researchers believe that stopping exercise at older age may trigger the processes connected to the development of dementia and other neurodegenerative conditions.
Larger brain, not different brain structure, differentiates us from primates
For a long time, scientists believed that our remarkable cognitive abilities are linked to the enlarged prefrontal cortex region of the brain. As the new article published this month shows, this idea was wrong. In both humans and non-human primates, the prefrontal cortex occupies 8% of the brain. Human brain, however, is much bigger and contains 16 billion cortical neurons, while other higher primates have only 6-9 billion of these cells. Apparently, this increased number of neurons, rather than larger prefrontal cortex, is behind our enhanced cognitive abilities.
Calcium supplements increase risk of dementia in women with history of stroke
Osteoporosis is a common problem in elderly women, and calcium supplementation is usually recommended to manage this condition. It turned out, however, that taking calcium supplements is not as safe as it was believed. Women with cerebrovascular diseases such as stroke and white matter lesions are at much higher risk of developing dementia when they regularly take calcium supplements. The risk is 7 times higher among women with a history of stroke who take supplements compared to women with a history of stroke who don’t supplement their diet with calcium. The molecular mechanism behind this phenomenon remains unclear.
Drugs for epilepsy may cause psychotic disorders
People with epilepsy are known to be prone to psychiatric disorders, but it appears that the part of problem is the very drug used to control epileptic seizures. New study revealed that in one out of seven epilepsy patients, the psychiatric disorders can be attributed to the use of this drugs. Women and people with temporal lobe epilepsy are particularly vulnerable to this side effect.
Better education of clinicians needed to avoid misdiagnosis of multiple sclerosis
Due to its rather unspecific manifestations and the lack of reliable biomarkers, multiple sclerosis (MS) can be a challenging condition to diagnose correctly. New study suggests that numerous patients misdiagnosed with other conditions received potentially harmful treatment for a disease they didn’t have. Moreover, the study also shows that in most cases the misdiagnoses were linked to not following the existing diagnostic guidelines and criteria correctly. Better education of clinicians is required to avoid misdiagnosis of MS and recognising patients who were diagnosed incorrectly.
