Unilateral neglect is when someone's brain doesn't pay attention properly to one side of their body. It's like when you are playing with a toy and you forget about the other toys beside you, but it happens with your body.
For example, imagine you have a line down the center of your body, one side is the right side, and the other side is the left side. When someone has unilateral neglect, they forget about things on one side. For instance, when they eat, they might only take food from one side of their plate or forget to finish eating their food on one side altogether.
People can also neglect the left or right side of their body or forget about things they see on one side, like not noticing something on the left side of a room or forgetting to write on the left side of a paper.
Unfortunately, this can be challenging for people because they do not notice or remember things that are important for their daily activities. Doctors work hard to help people with unilateral neglect manage it so they can live a happy and healthy life.
