A

Q

In withdrawal syndrome,

During the period of seizure activity
and for days afterwards, the patient is unusually sensitive
to stroboscopic stimulation; almost half the patients
respond with _______ or _________

A

of Victor ‘s patients with generalized withdrawal seizures
went on to develop ________ (the percentage has
been less in other series);

to medical attention

A

T
