[CLIP] The REAL Cause of Dementia You NEED To Know

Dr. discusses the critical insights into Alzheimer's disease, emphasizing that 95% of cases are preventable through lifestyle interventions. She highlights that dementia is not a natural part of brain aging, and women are particularly at risk. The disease typically begins in the 30s, with symptoms emerging in late 60s and 70s. Key factors contributing to brain health include exercise, cognitive reserve, and lifestyle choices. Resistance training emerges as a powerful intervention, with studies showing it can preserve and even enhance cognitive functions. The brain contains 87 billion neurons with up to 10,000 connections per neuron, and factors like sleep deprivation, poor diet, and lack of physical activity can gradually erode brain functioning. The expert emphasizes that genetic predisposition, such as the APOE E4 gene, does not guarantee disease development, but increases risk. Critically, exercise – particularly resistance training at 80% of one's maximum repetition – can release myokines that positively impact brain health, reduce inflammation, and support neurogenesis.
