Question 5

What is the EEG pattern of Creutzfeldt-Jakob disease?

Answer 5

~90% of patients will have generalized periodic sharp waves

Question 6

What is the EEG pattern of opioid intoxication?

Answer 6

Decreased alpha activity and increased voltage of theta and delta waves

Question 7

What is the EEG pattern of marijuana intoxication?

Answer 7

Increased alpha activity in the frontal area of the brain, with overall slowed alpha activity in the rest of the brain.

Question 8

What is the EEG pattern of caffeine withdrawal?

Answer 8

Increased amplitude or voltage of the theta activity

Question 9

What is the EEG pattern of nicotine withdrawal?

Question 10

What is the EEG pattern of barbiturate withdrawal?

Answer 10

Generalized paroxysmal activity and spike discharges.

Question 11

What chemical is often tested for in the CSF, blood, or urine to assess dopamine activity in the CNS?

Answer 11

Homovanillic acid (primary metabolite of dopamine).

Question 12

What blood test may be useful for distinguishing a tonic-clonic (grand mal) seizure from a non-epileptic seizure?

Answer 12

Serum prolactin level - tonic-clonic seizures are followed by a sharp rise in serum prolactin that lasts ~20 minutes. Prolactin levels do not change in non-epileptic seizures
