Brain health habits for maintaining cognitive function in old age

Maintaining brain health and cognitive function in old age involves more than just consuming new information; active output is essential for stimulating the frontal lobe. Psychiatrist Hideki Wada notes that while inputting new data is helpful, the frontal lobe also plays a critical role in how we express information. A decline in output—often seen in retirees who experience a sudden decrease in social interaction and professional communication—can lead to frontal lobe atrophy and symptoms such as repetitive speech.

To combat aging, experts suggest various habits that promote engagement and mental stimulation. Recommended activities for maintaining vitality include gardening, engaging in social interactions like visiting markets, reading aloud, composing short poetry (senryu), and painting. These habits provide a sense of progress and social connection, which are vital for long-term cognitive health.
