Norepinephrine Your Get Up and Go

Summary

An educational breakdown of norepinephrine, its role as the 'get-up-and-go' neurotransmitter, its impact on mental health conditions like depression and anxiety, and how it interacts with other bodily systems.

Highlights

Defining Norepinephrine and Its Functions00:00:26

Norepinephrine is the body's 'get-up-and-go' neurotransmitter, synthesized from dopamine. It acts as both a neurotransmitter and a hormone, mobilizing the brain and body for action, and is essential for vigilance, attention, motivation, and learning.

Norepinephrine in Clinical Depression and Aging00:06:18

The speaker discusses how norepinephrine levels impact cerebral aging, cognitive slowing, and behavioral flexibility. It is noted that the cause of depression is complex and likely involves more than just a simple neurotransmitter imbalance.

Fight-or-Flight and Physical Symptoms00:16:27

Norepinephrine is central to the fight-or-flight response, regulating heart rate, blood pressure, and glucose levels. Excess levels can manifest as anxiety and panic, while insufficiencies can lead to postural hypotension and fatigue.

Prolonged Stress and Neurotransmitter Depletion00:19:34

Chronic stress initially causes an overactive HPA axis but can eventually lead to hypo-cortisolism and norepinephrine depletion, resulting in apathy, low energy, and depressive symptoms.

Medications and Treatment Considerations00:32:13

The video reviews how various classes of medications, such as SNRIs and NDRI's, impact norepinephrine levels. Clinicians are encouraged to account for all medications and supplements a client is taking, as they can significantly influence mood and treatment outcomes.

Holistic Approaches and Vulnerability Prevention00:41:40

The speaker emphasizes that physical health—specifically sleep, diet, and stress management—directly influences the neurotransmitter system. Using mindfulness and vulnerability prevention, practitioners can help clients regulate their stress response effectively.
