How Overthinking Impacts Brain- A Story of Realisation and Transformation 

I must admit, I haven’t studied medicine or life sciences. But I do have a great interest, so I enjoy interacting with medical practitioners and trying to absorb their insights in a way that makes sense in layman’s terms. This story takes me back 20 years, to a time when the term “overthinking” wasn’t as commonly discussed as it is today. Recently, I came across an article on the subject, which brought back memories of an experience I was part of. My role in this story was simply to “listen”; the credit goes to my doctor friend.

 My friend Anand, a highly qualified professional with an impressive background from a premier engineering college and a top management school, always had the potential to excel. But over the years, I noticed he often appeared worried, confused, and indecisive—his tendency to overthink seemed to stall his career growth and overall happiness.

 One day, I decided to gently bring up the topic with him. With his permission, I introduced him to my friend, Dr. Kulkarni, a neurologist renowned for her understanding of the brain’s response to stress and overthinking. We visited her office together, where she shared insights that were both eye-opening and sobering.

 Dr. Kulkarni explained that overthinking, especially during times of stress, causes the brain to release high levels of cortisol, a stress hormone. The Lancet( World Leading general Medical Journal) published findings that chronic cortisol exposure can shrink the hippocampus—the part of the brain responsible for memory and learning. In Anand’s case, this constant stress was like an unwelcome guest, overstaying its welcome and impacting his focus and memory.

 Next, Dr. Kulkarni shared research from Nature Reviews Neuroscience that explored repetitive negative thinking, a hallmark of overthinking. She explained how this can lead to the buildup of beta-amyloid and tau proteins, markers linked to Alzheimer’s disease. Anand was shocked to learn that simply dwelling on the same negative thoughts could impact his brain’s physical health.

 Dr. Kulkarni also referenced a study in The Journal of Neuroscience, which showed how overthinking can impair decision-making, a concept known as “analysis paralysis.” Anand related to this immediately; he’d often found himself feeling trapped by endless decision-making loops, unable to move forward.

 Lastly, she spoke of findings from The American Journal of Psychiatry, revealing that excessive rumination can reinforce negative thought patterns, creating a cycle that can lead to anxiety and depression. Dr. Kulkarni encouraged Anand to break this cycle through mindfulness exercises, breathing techniques, and structured moments of reflection.

 With Anand’s permission to share this journey (and names changed for privacy), I hope it inspires others.

 After a year of our visit to Dr. Kulkarni, I noticed a remarkable improvement in Anand. He became more decisive, calm, and content, and his career found renewed direction. This experience taught me that overthinking is not just a habit; it’s a challenge with tangible impacts on mental and physical health—but it’s also one we can address with the right support and guidance of experts medical professionals and Yog experts,

 May this story encourage anyone who feels held back by overthinking. Small steps, the right support, and a fresh perspective can indeed make a lasting change.
