Louisa Nicola explains why Alzheimer’s disease and dementia are not conditions of old age but diseases that begin silently in midlife. Drawing on neuroscience and clinical research, she reveals how brain decline can start as early as your 30s long before symptoms ever appear.
She breaks down why genetics play a much smaller role than most people think and explains how lifestyle factors like sleep deprivation, inactivity, poor diet, and constant dopamine stimulation slowly erode the brain. Louisa also explains cognitive reserve, how the brain protects itself when properly trained, and why resistance training is one of the most powerful tools for preventing cognitive decline.
This conversation shows how small daily habits compound over decades and why protecting your brain early determines whether you stay sharp or decline later in life. It challenges the belief that dementia is inevitable and explains why most cases are preventable with the right interventions.
