In this episode, playwright Jake Brasch explores the intersection of cognitive health and personal experience through his semi-autobiographical play, 'The Reservoir.' He discusses the concept of cognitive reserve and its implications for aging and addiction recovery.

What Happened

In this episode of Science Friday, host Ira Flatow welcomes playwright Jake Brasch, who shares the inspiration behind his play, 'The Reservoir.' The narrative intertwines his struggle with alcoholism and the cognitive decline observed in his aging grandparents, leading him to explore the concept of cognitive reserve. This idea suggests that engaging in stimulating activities can help delay the onset of dementia, prompting Brasch to seek creative strategies to support both his recovery and his grandparents' cognitive health.

Brasch emphasizes that his exploration began with scientific research, particularly focusing on cognitive reserve and its implications for Alzheimer's. He mentions how these scientific insights helped him reflect on his own life, particularly the paradox of high cognitive function followed by sudden decline, as experienced by his grandmother. The play, while rooted in personal experience, also raises broader questions about memory, loss, and the complexities of aging, all while maintaining a balance of humor and gravity.

Key Insights

Key Questions Answered

What is cognitive reserve and how does it relate to aging?

Cognitive reserve refers to the brain's ability to improvise and find alternate ways of getting a job done. In the context of aging, engaging in mentally stimulating activities can enhance this reserve, potentially delaying the onset of dementia symptoms. Josh, the protagonist in Brasch's play, discovers that his experiences with alcoholism share similarities with the cognitive decline seen in his grandparents, leading him to explore how cognitive reserve might apply to both situations.

How did humor play a role in The Reservoir?

Humor is a vital element in Brasch's play, serving as a mechanism to discuss heavy themes like alcoholism and cognitive decline. Brasch notes, 'I firmly believe that you have to laugh to cry and you have to cry to laugh,' highlighting how humor can make difficult subjects more approachable. The play navigates the fine line between comedy and tragedy, reflecting the complexities of life and the emotional rollercoaster associated with family and health issues.

What personal experiences influenced the writing of The Reservoir?

Brasch's writing is deeply personal, rooted in his own battle with alcoholism and the decline of his grandparents' health. He explains that the science of cognitive reserve inspired him to confront his experiences, stating, 'I realized that those are largely the things that one does to get sober.' This semi-autobiographical approach allows him to explore themes of family, memory, and the process of coping with loss.

What does Brasch suggest about the nature of memory loss?

Brasch reflects on how memory loss can be unpredictable and non-linear. He states, 'the path of it is so mysterious,' which resonates with both Alzheimer's and alcoholism. His insights reveal that while some individuals may lose certain memories, they might retain others, complicating how we understand and navigate memory loss. This perspective invites audiences to consider the broader implications of memory and identity.

What themes does The Reservoir explore regarding family dynamics?

The play delves into intergenerational connections, illustrating how families cope with difficult topics through humor and shared experiences. Brasch emphasizes the significance of these connections, sharing how he channels his family's dynamics into the narrative. By blending personal stories with scientific inquiry, the play encourages conversations about aging and the relationships that shape our understanding of health and memory.
