Answer 5

(EEG) electroencephalogram

is a test that measures the electrical activity of the brain. It can be used to diagnose or monitor conditions that affect the brain, such as epilepsy and sleep disorders.

Question 6

EEG

- measures?

Answer 6

voltage fluctuations

resulting from
- current changes (from neurons)

Question 7

seizure classifications *3

Answer 7

1. focal onset
2. generalized onset
3. unknown onset

Question 8

class of seizure
- focal onset (1 of 3)

• sub classif. *2
• onset *2
• may progress to..

Answer 8

sub class (focal onset seizures)

1. aware = aware during, knowledge self, enviro, concious
2. impaired awareness = awake but not aware, no mem of

onset

1. motor onset
2. non-motor onset

may progress to
focal to
- bilateral tonic-clonic

Question 9

class of seizure
- generalized onset (2 of 3)

• sub classif. *2

Answer 9

sub class (generallized onset seizures)

1. motor = tonic-clonic or other motor
2. non-motor = absence seizures
