Timeless

Cozolino, a clinical psychologist writing here for a general readership, sets out a neuroscience of ageing built on the premise that the human brain remains a social organ into late life. He gathers research on attachment, stress physiology, and plasticity to argue that connection, not withdrawal, keeps the ageing brain adaptive, and that decline is far less fixed than convention assumes.

Across chapters on the social brain, attachment, wisdom, and the integration of body and mind, he treats relationships as biological infrastructure: warm bonds lower cortisol, buffer cardiovascular strain, and support the growth of compassion and perspective he groups under wisdom. Isolation, by the same logic, corrodes health.

For the clinician, the book carries attachment thinking across the whole lifespan and toward older patients, where loss, loneliness, and continued development sit at the centre of the work. Norton published it in 2018 for readers outside the consulting room as well as within it.
