What Causes Brain Depression? A Scientific dive into Depression and Anxiety
A Scientific dive into Depression and Anxiety.
In this video, we explore how depression affects the brain and uncover the science behind brain depression and anxiety. Backed by neuroscience and psychology, this deep dive reveals how depression rewires three major areas of your brain: the prefrontal cortex, hippocampus, and amygdala—and how these changes impact memory, mood, and decision-making.
If you’ve ever wondered what part of the brain is affected by depression, or how anxiety and depression are connected, this video explains it all—clearly and scientifically.
🌿 Why Watch This Video?
✔️ Understand the brain science behind depression.
✔️ Learn how depression and anxiety alter brain structure and function.
✔️ Discover healing methods like neuroplasticity, exercise, and therapy.
✔️ Boost your awareness of mental health and self-healing strategies.
📌 What You’ll Learn:
🔹 How the amygdala becomes overactive during depression.
🔹 Why the hippocampus shrinks, leading to memory loss.
🔹 How the prefrontal cortex struggles with focus and planning.
🔹 Ways to rewire your brain for emotional resilience.

Connection between autism spectrum disorder and myotonic dystrophy
A recent discovery of a molecular connection between autism and myotonic dystrophy, a type of neuromuscular disease, may provide a breakthrough on how clinicians approach autism spectrum disorder.
The new study by an interdisciplinary team of biomedical scientists, published in Nature Neuroscience, used myotonic dystrophy as a tool or model to learn more about autism – effectively using one disorder to better understand the other.
“We identified a new pathway that can lead to autism,” said the research lead. “We found that a genetic mutation in a certain gene can disrupt the expression of multiple autism-related genes during brain development, causing autism.”
DARPA-Funded Research Develops Novel Technology to Combat Treatment-Resistant PTSD
Groundbreaking research has revealed a new method of potentially eliminating hard-to-treat post-traumatic stress disorder (PTSD) diagnoses in patients by employing a novel kind of therapy: stimulation of the vagus nerve.
The new treatment offers new hope for those long afflicted by PTSD diagnoses that have traditionally proven to be resistant to conventional treatment methods.
Scientists from the University of Texas at Dallas (UTD) and Baylor University Medical Center conducted the research, discovering that participants were symptom-free for up to six months after completing the experimental therapy.
HIV Drugs Linked to Lower Alzheimer’s Risk
Summary: New research reveals a striking gap between people’s theoretical desire to know their Alzheimer’s disease risk and their real-life decisions when results are actually offered. In a study of cognitively normal volunteers, only 60% chose to learn their estimated risk when given the chance, despite 81% expressing prior interest.
Mammal’s lifespans linked to brain size and immune system function, says new study
So size does matter?
Mammal’s lifespans linked to brain size and immune system function, says new study.
The researchers looked at the maximum lifespan potential of 46 species of mammals and mapped the genes shared across these species. The maximum lifespan potential (MLSP) is the longest ever recorded lifespan of a species, rather than the average lifespan, which is affected by factors such as predation and availability of food and other resources.
The researchers, publishing in the journal Scientific Reports, found that longer-lived species had a greater number of genes belonging to the gene families connected to the immune system, suggesting this as a major mechanism driving the evolution of longer lifespans across mammals.
For example, dolphins and whales, with relatively large brains have maximum lifespans of 39 and up to 100 years respectively, those with smaller brains like mice, may only live one or two years.
However, there were some species, such as mole rats, that bucked this trend, living up to 20 years despite their smaller brains. Bats also lived longer than would be expected given their small brains, but when their genomes were analysed, both these species had more genes associated with the immune system.
The results suggest that the immune system is central to sustaining longer life, probably by removing aging and damaged cells, controlling infections and preventing tumour formation.
These 5 Hidden Health Risks Are Aging Your Brain Faster
Hypertension and other health risks accelerate brain aging, as shown in a 16-year study using MRI data and predictive modeling.
Chinese scientists have conducted a population-based cohort study to examine the long-term impact of unhealthy lifestyles, metabolic abnormalities, and other risk factors on brain aging. The findings showed that these factors significantly accelerate brain aging, and the researchers proposed strategies to support brain health. Their study was published in Research.
