In spite of the ongoing exquisite work of a multitude of researchers worldwide including governmental institutions like the National Institute on Drug Abuse (NIDA) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and for example in the United States the FDA Medication Assisted Therapy (MAT) embracing Opioid Replacement Therapy (ORT) in 2022, 111,000 people prematurely died from opioid induced overdose. It is estimated that if treatment stays as usual by 2025 the death rate will increase to 165,00.Therefore, we are encouraging the scientific and clinical community to at least consider our "out of the box" thinking whereby we are proposing a new paradigm shift involving the " dopaminergic homeostatic modeling approach and Genetic screening to early identify preaddiction.

Our hypothesis posits that a deficiency in gamma-type endorphins leads to persistent hyperdopaminergic activity, amplifying schizophrenia-related symptoms such as hallucinations. Thus, alcohol use may function as a physiological self-healing mechanism by increasing gamma-endorphin levels, thereby mitigating dopaminergic hyperactivity.

While the concept of RDS as the actual real umbrella of all mental illness unlike the current DSM-V (the brain is not carved out as portrayed by this important psychiatric manual) awaits further intensive research. In fact, Steven Hyman (former director of NIMH) suggests otherwise and has urged for research related to etiological causes instead to help explain the failings of mental health.

Pregnant Dom and Sub dams of generation 54 received THC (20 mg/kg, intraperitoneally) on gestation days 13, 15, and 17. Our findings indicate that PTE significantly reduced body weight (measured at postnatal day (PND) 7 and 30), increased anxiety-like behaviors in two-month-old Dom offspring, and enhanced sociability and reduced anxiety-like behaviors in Sub offspring.

A key area of research in neurobiology is the role of dopamine. Significant advancements have been made in uncovering the intracellular signaling pathways that mediate both dopamine's immediate effects and its long-term influence on brain function.

Despite recent developments in the clinical utilities of pharmacogenomics, it needs more investigations for uncovering the complicated mechanisms of drugs from a genetic standpoint. The research addresses the increasing misuse of opioids during recovery, emphasizing personalized interventions for opioid use disorder (OUD).

GLP-1 receptor agonists (GLP-1RAs) have shown promise for improving glycemic control and reducing weight through appetite regulation, delayed gastric emptying, and energy expenditure modulation. This narrative review explores the mechanisms of GLP-1-mediated glycogen metabolism and energy expenditure, particularly in key tissues-pancreas, liver, skeletal muscle, and adipose tissue.

Chronic opioid use is associated with hypodopaminergia-induced hyperalgesia, whereby dopamine depletion increases pain sensitivity. Patients with inherently low dopaminergic function are particularly predisposed to hyperalgesia and reduced pain tolerance.

The aim of the present study was to identify distinctive factors of these behavioral addictions, focusing on gratification and compensation, reward deficiency syndrome, and compulsivity among young adults.
Methods: The sample comprised 1459 Jewish Israeli young adults from the general community (36% male, 64% female; aged 19-27 years).
Background: Exercise enhances overall health, playing an important role in protecting against diseases that impact brain function. Studies show that physical activity influences several key biological processes, including dopamine signaling, brain glucose metabolism (BGluM), and social behavior.
Methods: Male sedentary and chronic exercise rats were examined for dopamine signaling and social behavior.

Background: Overdose involving opioids is the black heart of the addiction crisis. "Pre-addiction," as an encouraging concept by NIDA and NIAAA, seems best captured with the construct of dopamine dysregulation. Referring to the abundant publications on "Reward Deficiency Syndrome" (RDS), Genetic Addiction Risk Score (GARS) test, RDSQ29, and KB220, Pre-addiction can be referred to as "reward dysregulation" as a suitable suggestion.

Adolescents with substance use disorders exhibit high rates of co-occurring mental illness, with over 60% meeting diagnostic criteria for another psychiatric condition in community-based treatment programs. Comorbidities are influenced by both genetic (DNA antecedents) and environmental (epigenetic) factors.

Major Depressive Disorder (MDD) and Generalized Anxiety Disorder (GAD) are prevalent comorbidities related to a greater likelihood of poor treatment outcomes and prolonged treatment for Reward Deficiency Syndrome (RDS) behaviors. The current exploratory case study of a small cohort (n=3; f=2 m=1) used novel neurotechnology to treat co-occurring MDD and GAD with a multifaceted intervention that combines the novel bio-resonance neurotechnology (BRNT) referred to as NuCalm, to restore autonomic nervous system balance and dual hemispheric repetitive transcranial magnetic stimulation (rTMS) of the ipsilateral Dorsal Lateral Prefrontal Cortex (DLPFC) to treat the disrupted structural components of the brain. Neuroacoustic brainwave entrainment, electromagnetic frequency bio-resonance, and light-blocking combine to place patients into a parasympathetic dominant state.
