my child seems easily distracted

[GoldFox01]

I've noticed that my DD has been struggling with focusing on her schoolwork lately. Despite being a bright kid, she seems easily distracted and has trouble completing tasks on time. It's been affecting her grades and causing some frustration for both of us. I'm concerned about how this might impact her academic progress and self-esteem in the long run.
Just want to know, what others do in this situation?

How old is she? Is this something new or has she always been distractible? Can sheconcentrate on things she is interested in e.g. hobbies?

She's 13 years old. This distractibility is relatively new. She's generally been able to focus well in the past, especially on things she's interested in like her hobbies and certain subjects in school. But recently, it's been a struggle for her to maintain attention, even on tasks she used to enjoy.
