Dr. M's Women and Children First Podcast – Détails, épisodes et analyse

Today on Dr. M’s Women and Children First, we welcome one of the most important voices in modern child development and behavioral science, Mona Delahooke. Dr. Delahooke is a licensed clinical psychologist, internationally recognized speaker, and the author of groundbreaking books including Beyond Behaviors and Brain-Body Parenting. Her work challenges one of the deepest assumptions in modern parenting and education: that difficult behaviors are simply choices to be corrected. Instead, she invites us to ask a radically different question, what is the nervous system trying to communicate? This conversation sits right at the crossroads of neuroscience, attachment theory, polyvagal theory, developmental psychology, and the lived experience of parenting. In many ways, Mona’s work gives language to something clinicians and parents often feel intuitively but struggle to articulate: behavior is not merely compliance or defiance, behavior is biology expressed through the body. We explore how stress physiology, early attachment, sensory processing, trauma, neurodivergence, and autonomic nervous system states shape the way children interact with the world around them. We discuss why punishment-based models often fail vulnerable children, how “bad behavior” may actually represent adaptive survival responses, and why safety and connection are foundational to learning, resilience, and emotional regulation. For me personally, this conversation resonates deeply with the broader themes we often discuss on this podcast, the interaction between environment, physiology, immune health, metabolism, and neurodevelopment. Mona helps bridge the gap between cellular stress and relational stress, between body and mind, between physiology and behavior. If you’ve ever cared for a child with anxiety, ADHD, autism, sensory challenges, explosive behavior, school struggles, or chronic dysregulation, this episode offers both compassion and a fundamentally different framework. One that moves away from blame and toward curiosity. Away from control and toward connection. This is a conversation about seeing children more clearly. And perhaps, seeing ourselves more clearly too. Please enjoy this conversation with Dr. Mona Delahooke. Dr. M

Creatine and Microbiomes A new 2026 Cell Metabolism study explores a compelling and increasingly central idea in modern biology: the gut/brain/immune/metabolism axis is not just associative, it is mechanistic. Specifically, Dr. Lu and colleagues investigate how the gut microbiota can directly influence depressive behavior by reshaping systemic and neural metabolism. This is another in a long running list of papers describing the amazing work that bacterial commensal microbes do for us. In this case, our minds and moods. "Although peripheral-brain crosstalk regulates energy metabolism, its role in depression remains unclear. Here, we used metabolic profiling to reveal elevated fecal creatine alongside reduced plasma and cerebrospinal fluid creatine in both patients with depression and mouse depression models. Exogenous creatine produced antidepressant-like effects mediated by gut microbiota. Bifidobacterium pseudolongum was identified as a significantly reduced gut bacterial species in depression, correlating with impaired creatine absorption. Subsequent supplementation with Bifidobacterium enhanced the antidepressant effects of creatine. Mechanistically, B. pseudolongum-derived acetate promoted the creatine transporter (Slc6a8) expression in intestinal epithelial cells via histone acetylation. The Slc6a8 mediated the antidepressant-like effects of creatine. Neuronal creatine deficiency influenced energetic metabolism and neurophysiological function. In patients with depression taking antidepressants, co-administration of creatine and Bifidobacterium increased plasma creatine levels and reduced depression scores. These findings identify the Bifidobacterium-creatine combination as a promising antidepressant strategy and highlight the critical role of gut-brain energy metabolism in depression." "The brain, as an energy-intensive organ, relies on precise metabolic regulation to maintain synaptic plasticity, neurotransmitter synthesis, and stress response systems. Accumulating evidence implicates energy metabolism dysregulation as a hallmark of depression. Neuroimaging studies using positron emission tomography (PET) have identified marked glucose hypometabolism in the medial prefrontal cortex (mPFC) of patients with depression. Cerebral mitochondrial dysfunction and ATP imbalance have been mechanistically linked to depression progression. Notably, emerging studies emphasize the bidirectional interplay between peripheral metabolic signals and central energy regulation, which is fundamental to neural metabolism. Clinical observations such as fatigue, appetite dysregulation, and unexplained weight fluctuations in patients with depression further suggest systemic metabolic disturbances spanning peripheral organs and the CNS.." (Lu et. al. 2026) This is next-level medicine. Mental health can no longer be framed as a disorder of genetics, experience, or circumstance alone. This work opens a clearer window, showing how the microbiome participates as an active partner, shaping brain function through the metabolites it helps produce and deliver. Compounds like creatine are no longer just peripheral players. They become signals, fuel, structure, and information, bridging gut and brain, metabolism and behavior.... and more Enjoy, Dr. M

Screenshot On today’s episode of Dr. M’s Women and Children First Podcast, we welcome Halie Hauser, a pediatric clinician, storyteller, and quiet architect of early childhood connection. Halie is the creator of Storytime Explorers, a storytelling platform designed for toddlers and preschoolers that sits at the intersection of language, emotion, and human development. With a Doctor of Nursing Practice focused on pediatric primary care, she brings both clinical depth and creative intuition to the way she reaches children—and just as importantly, their parents. \ Her work lives in the small moments: friendship struggles, big feelings, daily routines, the courage to try again. The ordinary terrain of childhood—where, if we’re paying attention, the most important wiring is happening. Halie understands something we often forget in modern pediatrics: before a child can regulate, they must feel safe; before they can learn, they must feel connected; and before they can speak, they must be spoken to in a language that meets them where they are. Through storytelling, she’s building that bridge. This is a conversation about early brain development, emotional scaffolding, the power of narrative in shaping behavior—and how something as simple as a story can become a tool for resilience, attachment, and lifelong learning.

Sleep Part III Finally, the other elephant in the room related to sleep is STRESS. Stress alters the function of the hormone cortisol and can significantly alter night sleep function. There are three major chemicals that affect sleep: cortisol, adenosine and melatonin. In normal conditions, adenosine rises during the day making you sleepy, cortisol hits its low point at night and melatonin rises as the sun goes down. This combination puts pressure on you to feel sleepy and want to go to bed. Unfortunately, modern life has made many of us feel stressed and sympathetically fired up which affects cortisol function. Instead of being at its nadir at night, the stress response causes cortisol to rise at inappropriate times disrupting sleep onset and maintenance. Couple this stress with facebook addiction and screen induced melatonin suppression and you have a recipe for insomnia and disrupted sleep. (Hanson et. al. 2010)....Plus, a section on cellphones and driver knowledge. Enjoy, Dr. M

Epigenetics and Pregnancy Epigenetics is the study of environmental signals and their effects on our genes. Our genes are not altered so much as they are read and used differently based on the environmental inputs. Epigenetic effects are critical during the pregnancy period as the environmental signals can alter an offspring’s outcome both in good and bad ways. Making sure that we control for better environmental signal exposure while pregnant can go a long way to protecting our children’s DNA from dysfunction and thus their outcome with health. It is well known that chemicals are generally negative insults to our epigenome while anti-inflammatory whole foods are positive. These epigenetic marks can be conserved over multiple generations making them extraordinarily beneficial or dangerous. Here we will discuss the lifestyle mitigating factors for a positive pregnancy and newborn outcome....plus an ode to Brenda Wassum. Dr. M

Sleep Part II Let us pause here! So far we now know that humans at all ages will suffer from memory dysfunction and brain sewage cleanup problems leading to inflammation and damage long term. What ages are most at risk? They are likely mirrored by other physiologic events that are at risk based on age. Teenagers, infants and toddlers are rapidly growing creatures requiring more macro/micronutrients, water, and toxin avoidance for success. It is likely that sleep follows these same principles. Going to a simple google scholar search for "sleep deprivation age risk" brings up countless articles on the effects of sleep deprivation in mothers and children on risk of obesity, diabetes, premature birth and much more. ....Plus more on gender and emotion as well as a recipe of the week. Enjoy, Dr. M

Sleep Update for 2024 Sleep has always been a necessary function of everyday life for all mammals. From an evolutionary perspective this cannot be a mistake as during the period of sleep you are vulnerable to predation. Therefore, there has to be a really good reason for mammals to sleep for extended hours. What is that reason? Why are toddlers and frankly all of us more cranky when we do not sleep enough? Why are our genes tied so tightly to circadian rhythms? Why are people so metabolically unwell when they are sleep deprived? ...plus updates on heat exhaustion and covid. Enjoy, Dr. M

Klotho Part II Last week we discussed Klotho as a protein that has pleotrophic effects in the body as it relates to cellular aging. This week let us focus specifically on the brain. What are the effects of klotho as it relates to cognition and function over time? Klotho has neuroprotective effects based on studies that show that better cognitive performance in translational models over time occur with the injections of klotho. Klotho is also shown to have neuroprotective effects if naturally elevated, i.e. individuals with host genetics that promote more klotho production over time without being taken or given. The pivitol research occurred in 2015 in a mouse model of Alzheimers Disease (AD) where Dr. Dena Dubal and colleagues looked at two groups of intervention mice with and without higher levels of Klotho. and a literature review on micro plastics and screentime.
