Patients mainly show a sudden onset of a transient loss of consciousness, usually lasting from a few seconds to tens of seconds, patients can experience a sudden cessation of activity, objects in their hands suddenly fall to the ground, call out and stare blankly, but most patients do not fall. If the patient occurs frequently, antiepileptic drugs should be given for treatment, commonly used drugs are clonazepam and ethosuximide, and at the same time should be given to improve brain metabolism treatment. It may also be a manifestation of pre-dementia, which is usually seen in elderly people over 60 years old, and patients may suffer from memory loss, inattention and disordered thinking at the same time.
