Early life factors and brain health
Our brain is changing most rapidly early in life. Even before we are born, almost all the 86 billion neurons we will ever have, are already in place. This forms the foundation of our brain. From the moment of conception, throughout life, the interaction between genes and the environment will impact the brain and cognitive functions such as memory and attention. The brain is especially vulnerable during pregnancy, and the environment in the womb plays a critical role for how the brain develops, with potential long-term effects on health. These early life factors may promote both positive and negative outcomes for the individual.
