How do you manage your easily excitable 10 year olds?

[Dotparkens]

Looking for advice on how to cope with a 10 year old who never calms down, can’t stop talking apart from when she’s asleep and has very unusual actions during the day as she cannot sit still. It’s become a concern to me as she often has full conversations to herself and even replies which scares me that it’s a mental health issue at play.
Her excitement is too much, the smallest thing and she is jumping and screaming like a 3 year old who has never seen these particular things before and she has to be firmly told to stop or it lasts for hours. I know all children get excited and it’s normal and expected, but this is to the extreme.
She can talk without stopping for hours, often needs reminding to take a breath! She is extremely exhausting to be around, never mind how tired she must feel bouncing off the walls all day.
School have no concerns as she doesn’t act like this there, which to me makes me think she is aware of her actions or possibly masking at school?
I have no idea where to start in finding out how to encourage her to calm and learn to have some quiet time and rest. It’s got to the point where people roll their eyes as she mentally drains them, children avoid her and adults tune out when she talks.
Is there something SEN going on here possibly or are some children just overly hyper? Is she likely to grow out of it? It only began when she turned 8 years old, she used to be calm.

Dealing with a 10-year-old who is constantly active and talking can be exhausting and concerning. While some level of high energy is normal, the intensity of her excitement and difficulty calming down might point to underlying issues such as ADHD, sensory processing problems, or challenges with emotional regulation. If her behavior is different at school, she may be masking her true self or struggling with impulse control.

To manage this, consider seeking a professional evaluation from a pediatrician or child psychologist to determine if there's an underlying condition. Establishing a structured routine with quiet times and calming activities can help her manage her behavior. Positive reinforcement, clear boundaries, and relaxation techniques might also be beneficial.
Additionally, integrating quiet activities like reading and drawing into her day and providing social skills training could improve her interactions and behavior. Approaching the situation with understanding and patience while seeking professional guidance is key.
