Is there hope for my husband’s sleep issues?

Is there any medication or treatment for an overly active sleeper? My husband flails at night, or roughly grabs ahold of me, to the point where he’s bruised me or even pulls clumps of my hair out. I know he can’t help it so I’m not mad about it, but if he sees a doctor is there anything that can be done? It’s to the point where I’m really starting to think about sleeping separately. He pulled a huge fistful of my hair out tonight when I shifted the position I was laying in 😭

He has said he doesn’t have nightmares, so I don’t think it’s terrors. Has anyone else had a problem like this? I really don’t want to have to sleep separately but if I so much as move he attacks me! I’ve had my nose bloodied and everything. I don’t know if he thinks I’m falling out of bed or what but it’s a huge problem for us. He feels so bad about everything and I just want a good nights sleep for once.
