Dear friend, welcome to HCM.
She could be having non-convulsive seizures (fits
may occur after fits foe variable time.
You need to see a good neurologist
to differentiate her diagnosis.
Consider a neuro opinion, CT/ MRI
scan and other necessaery tests on evaluation ( if your doctor is not a neurologist)
Untreated, the situation may worsen.
I hope to have guided you well. Take care and get her well soon.
