Memory, ADHD, and Enhancing Brain Health with Dr. Charan Ranganath

Dr. Charan Ranganath, a professor of psychology and neuroscience at UC Davis, joins the podcast to discuss the science of memory and practical ways to enhance cognitive function. Some key points from the conversation:

• Memory isn't just about the past, but about using past experiences to make sense of the present and anticipate the future. Our understanding of the present is heavily informed by our memories.

• The hippocampus plays a key role in linking experiences to context and forming episodic memories of specific events. The prefrontal cortex is important for cognitive control and regulating our thoughts and actions based on goals.

• Curiosity and dopamine play an important role in memory formation. Being in a curious state can enhance memory for both relevant and incidental information.

• Lifestyle factors like sleep, diet, exercise, and social engagement have a major impact on cognitive health as we age. Making positive lifestyle changes can significantly reduce risk of cognitive decline.

• ADHD involves difficulties with cognitive control and executive function. Dr. Ranganath shares his personal experience with ADHD and strategies he uses to manage it.

• Deja vu likely results from a mismatch between a strong sense of familiarity and an inability to recollect the specific memory, creating an uncanny feeling.

• Our memories are not fixed, but can be updated and reframed through retrieval and reconsolidation. This has implications for treating conditions like depression and PTSD.

• Limiting distractions and multitasking is important for memory formation. Focusing on one task at a time allows for more cohesive memory encoding.

• Having a sense of purpose and engaging in cognitively stimulating activities is beneficial for brain health as we age.

• Taking care of sensory health like vision and hearing is important for cognitive function. Getting hearing aids if needed can help reduce risk of cognitive decline.

The conversation covers a wide range of topics related to memory, brain health, and cognitive function, providing both scientific insights and practical advice for enhancing memory and mental performance throughout life. Dr. Ranganath emphasizes the importance of lifestyle factors and intentional practices for maintaining a healthy brain as we age.
