Research has shown physical movement to be a powerful tool in alleviating symptoms of depression and anxiety, as well as enhancing our overall sense of well-being. As we enter the sunshine and blue skies of Hot Texan Summer (TM), it is helpful to remember the beneficial effects of movement on our mental health and the importance of incorporating physical activity into our daily lives.

Over the years, a growing body of research has shed light on the positive impact of physical activity on individuals experiencing depression and anxiety. These studies highlight several key findings:
 
Release of Mood-Boosting Chemicals. Engaging in regular physical activity triggers the release of endorphins, neurotransmitters that act as natural painkillers and mood elevators. Endorphins induce feelings of happiness and well-being, counteracting negative emotions. This chemical boost can significantly improve mood and reduce symptoms of anxiety.
 
Neurogenesis and Neuroplasticity. Movement has been shown to promote neurogenesis (the formation of new neurons) and enhance neuroplasticity (the brain's ability to reorganize and adapt). These processes play a vital role in improving cognitive function, memory, and learning abilities. By stimulating the growth and connectivity of brain cells, physical activity helps create a healthier neural network that supports mental well-being. Studies indicate that regular exercise may even significantly reduce the risk of developing dementia.
 
Stress Reduction and Anxiety Management. Movement acts as a natural stress reliever by reducing the levels of stress hormones such as cortisol and promoting relaxation. Regular activity can also help manage anxiety symptoms, which often coexist with depression. Engaging in activities like walking, jogging, yoga, or swimming can provide a much-needed respite from daily stressors, promote a sense of calm and mental clarity, and improve sleep.
 
Social Interaction and Support. Participating in group activities or team sports provides an opportunity for social interaction and support. Engaging in activity with others can foster a sense of belonging and community, creating a supportive environment that combats loneliness and enhances our sense of well-being.
 
Physical activity can be a powerful a complementary tool alongside professional treatment for depression and anxiety. A recent meta-analysis published in JAMA Psychiatry, found that relatively small doses of even moderate physical activity (2 hours per week) were associated with substantially lower risks of depression. (Dr. Roger Seheult examines this and another recent study exploring depressive symptoms and sedentary behavior in adolescence in the video linked below.)

Traumatic Brain Injury (TBI) and concussions have increasingly made headlines, particularly in the context of sports-related injury. An increasing number of hospitals and outpatient clinics have opened units dedicated to improving diagnosis and rehabilitation for TBI patients. As we work to advance research and treatment, it is important to recognize the real people behind the statistics and brain imaging, to understand how these devastating losses impact their everyday lives. 

Artificial Intelligence professor Dr. Clark Elliott suffered what was initially thought to be a mild-traumatic brain injury when his car was rear-ended in 1999, an accident he walked away from. However, in the weeks, months, and years that followed, Dr. Elliott suffered a constellation of cognitive and emotional symptoms resulting from that TBI that threatened his family life and once promising career.

Dr. Elliott's new book, The Ghost in My Brain: How a Concussion Stole My Life and How the New Science of Brain Plasticity Helped Me Get It Back, describes in unblinking detail the often confusing changes that took place in his ability to think and function following the accident. Importantly, the story goes on to examine emerging research in neuroplasticity, the amazing ways in which the brain heals itself, and the innovative behavioral optometry treatment that Dr. Elliott credits for bringing him back to himself. It is a remarkable story, and well worth the read for those who have suffered TBIs, as well as for those who love and treat them.
