It was long believed that neurons in the human brain were incapable of growth and repair after maturity. We now know this to be false and that the human brain retains the potential for self-renewal throughout our lives. Even more exciting is that self directed neuroplasticity is a real possibility.
Neuroplasticity: The ability of the brain to form and reorganize synaptic connections, especially in response to learning or experience or following injury. Even more exciting is that self directed neuroplasticity is a real possibility.
Neurogenesis: is the process by which neurons are generated from neural stem cells and progenitor cells.
Brain-derived neurotrophic factor (BDNF): A growth factor encoded by the BDNF gene that promotes both neuroplasticity and neurogenesis.
Much to the chagrin of the pharmaceutica industry, there is no “silver bullet” for preventing and reversing cognitive decline and diseases like Alzheimer’s and Parkinson’s. Instead, what we do have is “silver buckshot” in the form of numerous dietary and lifestyle interventions that can increase the body’s production of BDNF.
Things you can take to increase neuroplasticity, and neurogenesis and BDNF levels include:
For starters, I take issue with the word “disorder” in attention deficit disorder (ADD). It’s not a stretch to suggest that ADD is actually a normal physiological response to the many insults of the modern world. The hyper-vigilance, distractibility, and impulsivity of ADD could all be predictable evolutionary adaptations intended to help us be safer and more successful in stressful environments.
Stress is not just mental, it quickly jumps to a physiologic effect. When the brain perceives stress, it sends both chemical and nerve signals to the adrenal glands ordering them to make two short-term stress hormones [epinephrine and norepinephrine] and the long-term stress master hormone cortisol. Not eating regularly enough and getting low blood sugar also spike cortisol levels. Cortisol is now known for promoting the dreaded stress-gut that gives chronically stressed people that apple shape.
Epinephrine and norepinephrine both promote the “fight or flight” response to the world by stimulating increased tone in the sympathetic nervous system. Other attributes of the “sympathetic state” are the tendency to freeze up, tense muscles, shallow breathing, and divert blood flow away from the extremities and digestive tract toward the large muscles. The sympathetic nervous system also interrupts digestion and makes it harder to concentrate and integrate and make new memories. If you have ever had trouble getting someone else (or yourself) to see a new point of view in a heated argument, you can probably thank the sympathetic nervous system for that gem of human psychology.
It all makes perfect sense if you think about it; if your body senses a threat (stress) it gets everything ready for a fight or flight from danger. Cortisol helps us prepare for stress by mobilizing resources to raise blood glucose and cholesterol. This sugar boost is good if you’re about to sprint away from an angry rhinocerous, but not so good (AKA promoting diabetes and heard disease) if the stress is an email or a phone call.
Improving Mood, Clearing Perception & Breaking Addictions with Nutritional Neurotransmitter Support
If you are struggling with anxiety, depression, obsessive tendencies, attention defecits or even some addictive tendencies, there is a good change that you could benefit from a leg-up in the form of nutritional neurotransmitter support.
The human body uses chemical messengers in the form of neurotransmitters to relay signals between and within our nervous system and our somatic body. Various neurotransmitters jump across the synaptic space between our nerves and other cells (muscles, sensory organs, glands…) in a highly controlled manner.
The concert of making, transporting, releasing, binding, degrading and reuptaking various neurotransmitters controls everything from our breathing & heart rate, appetite & digestion, all voluntary and involuntary movement, our reflexes, and all five of our senses.
