Parkinson’s Disease
While it might start as a little shakiness in your hand, Parkinson’s can eventually affect how you walk, talk, sleep, and think. Even early on, it can lead to things like obsessing over small details or a sudden carelessness.
Later, you may seem absent-minded or not as social as you used to be. And it gets harder to keep your thoughts going in one direction.
Huntington’s Disease
This is an illness you’re born with, but it usually shows up in your 30s or 40s. It damages brain cells and affects every part of your life.
You might have a hard time thinking clearly, or get angry to the point of hitting walls, or ignore basic things like brushing your teeth. And you may not even be aware it’s happening.
