Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward system and the hippocampus, the region responsible for memory. A protein called DeltaFosB builds up with continued drug use and acts like a genetic switch, altering how neurons function and strengthening the brain’s drive to seek cocaine.

When this protein drops, dopamine neurons fire more intensely, strengthening new associations in ways that resemble how addictive behaviors take hold. Rat studies showed that even brief, synchronized bursts of neural activity can amplify reward learning, offering insight into why everyday triggers, like a morning routine, can provoke strong cravings.

Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the brain’s reward hub.

These discoveries may help create treatments that keep the benefits of weight loss while reducing unwanted side effects.

Early trials show reductions in alcohol intake, opioid seeking, and nicotine use. Though more research is needed, scientists believe these drugs could open a powerful new front in addiction therapy.

Researchers at Scripps Research have discovered that a tiny brain region called the paraventricular nucleus of the thalamus (PVT) becomes hyperactive when animals learn that alcohol eases the agony of withdrawal. This circuit helps explain why people relapse: their brains learn that alcohol brings relief from stress and anxiety.

Marketing of diet-focused processed foods in the 1980s may have played a major role. Food addiction was linked to poor health, weight issues, and social isolation, highlighting long-term risks. Experts warn that children today could face even higher addiction rates in the future.

In a study of more than 400 patients, roughly one in five experienced heightened taste sensitivity, and many reported being less hungry and more easily satisfied.

The study, detailing these epigenetic mechanisms in the brain, uncovers a new molecular target for the development of novel SUD treatments.

A preclinical rodent model implicated a gene called Shisa7 as the key predictor. A new study provides valuable insights into the neurobiological mechanisms underlying heroin addiction and may have implications for the development of innovative strategies to combat the ongoing opioid epidemic.

Endocannabinoids bind to cannabinoid receptors throughout the body that regulate activities, such as learning and memory, emotions, sleep, immune response and appetite.

Researchers transformed dysfunctional memories stored in the brain through processing and integration. EMDR was as effective as cognitive behavioral therapy for cravings with the combination of both resulting in more reduction in craving than cognitive behavioral therapy (CBT) alone. Both groups (experimental group and control group using only CBT) had clinically significant reductions in cravings, repetitive negative thoughts, and irrational cognitions, with the experimental group showing greater decreases overall.   Tue, 14 Nov 2023 14:37:28 EST https://www.sciencedaily.com/releases/2023/11/231114143728.htm https://www.sciencedaily.com/releases/2023/11/231108115119.htm Results from a new clinical trial suggest that a group of brain regions known as the 'salience network' is activated after a drug is taken intravenously, but not when that same drug is taken orally. When drugs enter the brain quickly, such as through injection or smoking, they are more addictive than when they enter the brain more slowly, such as when they are taken orally. However, the brain circuits underlying these differences are not well understood. This study offers new information that helps explain what may be causing this difference.

It results from a damaged or malfunctioning nervous system, stemming from diseases like diabetes, alcoholism, strokes, Parkinson's and other causes like spinal nerve compression, radiation and chemotherapy treatments. Management of neuropathic pain has been particularly challenging as currently prescribed drugs, such as anticonvulsants and antidepressants can have severe adverse effects, are not well-tolerated, take a longer time to work only help a subset of patients.

The authors suggest that, even in the absence of documented evidence, clinicians can use patients' self-reported experiences of abuse and neglect to identify those at risk of developing mental health difficulties and provide early interventions.

The brains of those who had not developed an addiction following childhood maltreatment seem to process emotion-related social signals better.

This dataset -- one of largest and most diverse of its kind -- may help reveal new treatment targets across multiple substance use disorders, including for people diagnosed with more than one. The findings also reinforce the role of the dopamine system in addiction, by showing that the combination of genes underlying addiction disorders was also associated with regulation of dopamine signaling.

But how reliable brain imaging is for detecting traits has been a subject of wide debate. Researchers now report that stronger links between brain measures and traits can be obtained when state-of-the-art pattern recognition (or 'machine learning') algorithms are utilized, which can garner high-powered results from moderate sample sizes.

Yet its neural basis -- or, how the brain gives rise to craving -- is not well understood. In a new study, researchers from have identified a stable brain pattern, or neuromarker, for drug and food craving.
