It all started with minor slips easily dismissed as “senior moments”
You forgot your keys. You called someone by the wrong name. The word you were looking for was on the tip of your tongue, but you couldn’t quite grasp it. You don’t feel any older, but you do feel yourself changing. Researchers agree this could be a sign of something more serious.
A study published in the British Medical Journal of January 2012 has concluded that age-related cognitive decline begins much earlier than expected: by our mid-40s. Even more distressing, this decline can progress at very unpredictable rates. Scientists have identified that acetylcholine, a key neurotransmitter, is responsible for forming new connections and strengthening neural pathways in the brain. In other words, it keeps your mind sharp. However, persistently low levels of this key neurotransmitter places you at risk. Without healthy levels of acetylcholine, the brain can physically shrink; at which point, the damage can be very difficult to repair.
And yet, we all know people of advanced age who seem immune to this cognitive decline.
