Memory and the Brain: Understanding the Complexity
Neuroscientist and author Lisa Genova discusses memory and its relation to normal brain function. She recounts a personal experience of forgetting where she parked her car, which she explains was an issue of distraction rather than memory loss. Genova dismantles the misconception that memory should be perfect, emphasizing that forgetting is a normal part of human brain function. She explains the four steps of memory creation: encoding, consolidation, storage, and retrieval. Genova also provides insights into how memory works and offers practical tips for supporting brain health throughout our lives.
The Interplay Between Memory and Health
Genova highlights the significance of memory in various aspects of life. She indicates that memory is essential for efficient movement, recognizing people, maintaining personal identity, and recalling personal histories. While our memory capacity is limitless, she explains that memory is fallible and depends on meaningful and repetitive input. Genova encourages establishing healthy lifestyle habits, such as getting enough sleep, managing stress, exercising, and staying socially and cognitively active, to support memory function.
Expanding Understanding of Neuronal Diseases through Literature
Lisa Genova discusses her journey of writing novels that depict the human experience of living with neurological conditions. She explains how fiction can demystify and destigmatize these conditions while humanizing individuals who have them. Genova's novels have become resources for both patients and medical professionals, providing insight into the emotional, physical, and practical aspects of these diseases. She emphasizes the importance of empathy and connecting with others on a human level, regardless of the challenges they face.
Future Perspectives and Personal Agency in Brain Health
Genova addresses the future of neurological diseases, focusing specifically on Alzheimer's and ALS. While there is ongoing research and drug development for Alzheimer's, prevention and a cure are not yet within reach. In the case of ALS, little is known about its causes or how to prevent it. However, Genova underscores the importance of being proactive in brain health by embracing healthy habits and making impactful choices to support overall well-being. She encourages readers to approach others with understanding and compassion, emphasizing that emotional connections can transcend the limitations of memory.
Our brains are magnificently complex - and highly fallible. This hour, neuroscientist and novelist Lisa Genova explains how to keep our brains healthy and what to do when something goes wrong.
