The Young and the Restless (Y&R) spoilers reveal that we have to ask: Is Mariah Copeland’s (Camryn Grimes) brain tumor twist on the way? Is that how Mariah’s out-of-character behavior will finally be explained?

Mariah has been doing things that don’t make sense for several months now, but what if there’s a good reason why?

Ian Ward’s (Ray Wise) return definitely affected Mariah, but there may be more to the story.

Mariah met Will Hensley (Michael Swan) on a business trip and nearly killed him, so that was obviously extreme and not something she’d normally do.

Back when J.T. Hellstrom (Thad Luckinbill) turned abusive, his aggressive streak was later explained through a brain tumor diagnosis.

Could Mariah have a brain tumor of her own?

Y&R certainly loves to repeat storylines!

That’s why we’re constantly seeing kidnapping after kidnapping, including Dominic Winters’ (Ethan Ray Clark) current abduction drama.

Mariah’s decision to snatch Dominic left fans scratching their heads.

It’s true that Mariah was overly attached to Dominic after she first gave birth to him, but she hasn’t really talked about or paid much attention to Dom since then.

It’s weird for Mariah to suddenly be fixating on Dominic again.

Even Mariah herself struggled to make sense of why she was kidnapping Dom and had to rely on Ian to talk her through it.

That brings us to all these Ian hallucinations, which might be another brain tumor warning sign.

Mariah has gotten progressively worse despite her extended stay at that clinic in Boston.

What if the reason they couldn’t help Mariah is because a brain tumor has been steadily growing this entire time?

It’s an option worth considering since Mariah’s behavior is so out of control.

Nothing Mariah’s doing adds up, so maybe a brain tumor has driven her to this breaking point.

If so, that could totally change Tessa Porter’s (Cait Fairbanks) perspective on everything that’s happened and could perhaps leave her torn between Mariah and Daniel Romalotti Jr. (Michael Graziadei) down the road.

Of course, it’s also possible this is truly just a mental break storyline, but it’s wise to consider all possibilities as we all look forward to Dominic’s safe return to Devon Winters (Bryton James) and Abby Winters (Melissa Ordway).

The Young and the Restless spoilers say Mariah will ultimately get the help she needs one way or another, so we’ll bring you updates on any news related to her condition.
