Neurogenetics is a field of science that studies how genes influence the development and function of the nervous system. It explores the relationship between genetic variations and neurological conditions, helping researchers understand how certain genes can contribute to disorders like Alzheimer's disease or Parkinson's disease. By examining the genetic makeup of individuals, neurogenetics aims to identify specific genes that may be responsible for these conditions. This knowledge can lead to better diagnostic tools and potential treatments, ultimately improving the understanding of how our genes affect brain health and behavior.
