Hi,
There is likely possibility of convulsion (seizures) in your mother's case.
I want to know -
During period of shaking is she able to communicate / consciousness during episode.
Is there involuntary passage of urine or stool.
Is there tongue bite or frothing from mouth.
Duration and frequency of episodes.
After episode is she become unconscious, unresponsive.
Cause of her congestive
heart failure.
Medications she is on.
Other illness like diabetes, blood pressure problem medicine for it.
Possible causes for convulsion in her-
1)
Cardiac arrhythmia abnormal electrical activity of heart which leads to impaired blood supply to brain which leads to convulsion.
2) Cardo-embolic event.
3)
Hypoglycemia (
low blood sugar) this is more likely in diabetes on treatment.
4) Impaired blood supply to brain due to blockage in brain arteries.
I would like to advise you-
1) Consult your cardiologist, there may be need for neurological evaluation by
neurologist.
2) EKG, 2DEcho of heart.
3) Metabolic profile blood sugar level, kidney function test, liver function test, electrolytes.
4) Brain imaging like MRI with angiogram.
