What are intention tremors?

An intention tremor is when your hand shakes more as you try to do something precise, like reaching for a toy.

Imagine you're trying to grab a small crayon from the table. Your hand starts moving toward it, but just before you touch it, it starts shaking, kind of like a wiggly robot trying to reach something important. That shaking is an intention tremor. It happens because your brain is working hard to control your hand, but something is making it harder than usual.

Think about riding in a car that’s going smoothly on the highway, no problems there. But when you try to park it, or turn into a narrow street, the car wobbles more. That's like an intention tremor, it's not shaking all the time, just when you're trying to do something tricky.

This can happen to some people when they have certain brain conditions, and it’s especially noticeable when they’re doing things that need a lot of control, like drawing or buttoning a shirt.
