By: Daniel J. Siegel MD


Embark on a journey to understand and combat depression through the lens of neuroscience in this summary of ‘The Upward Spiral: Using Neuroscience to Reverse the Course of Depression, One Small Change at a Time’ by Daniel J. Siegel MD. Uncover the role our brains play in depression, the distinction between anxiety and worry, and the impact of habits, exercise, decision-making, sleep, and gratitude on mental health. By exploring these essential elements, you will gain valuable insights into combating depression and fostering an upward spiral towards emotional well-being.

Demystifying Depression

Depression is a complex mental state that results from a malfunctioning prefrontal cortex. The limbic, or ‘feeling’, brain is responsible for emotions such as stress and anxiety. The prefrontal cortex regulates the limbic system under normal circumstances. However, when the prefrontal cortex is not functioning correctly, negative emotions begin to get out of control. A person who is facing depression may continue spiraling downwards, with the factors that trigger it varying from person to person. Anxiety and worry are leading contributors to depression, and it can lead to chronic depression in the worst cases.

Breaking the Loop of Worry and Anxiety

The prefrontal cortex, responsible for planning, is also in charge of worrying, and when triggered, worrying can lead to anxiety. Anxiety is the experience of potential problems as though they are actually happening. Worry and anxiety exacerbate one another, resulting in a downward spiral. The loop is difficult to break, as worry disrupts the prefrontal cortex’s important job of making plans and considering potential problems.

Overcoming Depression: The Importance of Positive Feedback

Depression leads to a negative focus on events, keeping the individual trapped in a downward spiral. The brain’s tendency to focus on emotional events is stronger for some people, leading to a negative outlook on life. This pessimistic outlook is worsened by bad habits. Pleasurable activities like comfort eating release dopamine, requiring more repetitions to get a chemical fix. The part of the brain responsible for habits, called striatum, prompts repetition of bad habits, worsening the depressive state. To overcome this, individuals should seek positive feedback to balance the negative impact of depression on their outlook.

Exercise as a Depression Fighter

Exercise fights depression on physical, mental, and social levels, improving sleep, increasing energy, reducing anxiety and stress, and getting individuals out into the world. People who are depressed usually assume that physical activity won’t help but every little bit will create an upward spiral. Even small changes such as walking after breakfast or taking a walk in between work, releases positive chemicals.
