Brain has five eras, scientists say with adult mode not starting until early 30s
Guardian3 days
Brain development follows five distinct phases with major turning points that determine cognitive capacity and vulnerability. The most significant shift occurs at 32 when adolescent-like changes end and adult brain architecture stabilizes for three decades. These phases explain why certain mental health risks and learning difficulties emerge at specific life stages.
Cognitive decline after 22 isn't inevitable but results from lifestyle factors starving the brain of proper inputs. While processing speed drops, crystallized intelligence and wisdom actually improve with age. Strategic interventions like novelty training, dopamine protection and mitochondrial support can maintain mental sharpness indefinitely.
