Understanding Neurodegeneration
Neurodegeneration is kind of like a withering of the brain's wiring. Our brain relies on these special cells called neurons to send messages around, letting us think, move, and feel. In neurodegenerative diseases, these neurons slowly lose function and eventually die. It's like the wires in your house getting old and frayed, only instead of lights flickering, it affects your memory, movement, or other brain functions. Here's a breakdown of what happens: Neurons malfunction: Neurons either stop working properly or die altogether. This disrupts the messages zipping between them. Many diseases, one process: There are different neurodegenerative diseases, like Alzheimer's or Parkinson's, but they all involve this loss of neurons. Gradual decline: These diseases worsen over time as more and more neurons get damaged. Symptoms start mild and become more severe as the disease progresses. Why does this happen? The exact reasons aren't fully clear, but s
