The diversity and abundance of gut microbes vary over the lifetime of an individual. It is low during the first three years of life when a stable gut microbiome is being established, reaches its maximum during adult life, and decreases as we grow older. The early period of low diversity coincides with the vulnerability window for neurodevelopmental disorders such as autism and anxiety, while the late period of low diversity coincides with the development of neurodegenerative disorders such as Parkinson’s and Alzheimer’s disease. One may speculate that these low diversity states are risk factors for developing such diseases.
