19
Q

located at the back of the head

A

occipital lobe

20
Q

for visual information

A

occipital lobe

21
Q

symptoms include visual disturbances, temporary blindness, headache, & difficulty with spatial ORIENTATION

A

occipital lobe

22
Q

located behind frontal lobes

A

parietal lobe

23
Q

for processing sensory info

A

parietal lobe

24
Q

symptoms: tingling or numbness, difficulty understanding spatial RELATIONSHIPS or distances, dizziness, vertigo, difficulty reading and writing, altered pain sensations

A

parietal lobe

25
located behind forehead
frontal lobe
26
for movement, planning, decision-making, emotion regulation
frontal lobe
27
symptoms: jerking movements, difficulty speaking or slurred speech, abnormal sensations, out-of-body experience, impaired awareness, confusion, changes in mood or behavior
frontal lobe
28
at either side of head, behind the temples
temporal lobe
29
for memory, learning, emotions, and auditory information
temporal lobe
30
symptoms: auras, altered awareness or confusion, automatisms, auditory hallucinations, difficulty speaking or understanding speech
temporal lobe
31
damage to this lobe does no affect the consciousness
temporal lobe
32
T/F: when temporal lobe is damaged, px may not be conscious during seizure episode
F - px may stay partially conscious
33
repetitive movement (e.g., lip smacking, chewing, or fidgeting)
automatisms
34
who are at increased risk for seizures and epilepsy (MCHS)
px with 1. mental retardation 2. cerebral palsy 3. head injury 4. stroke
35
focal neuronal injury is associated in the onset of seizures in ___________
elderly
36
focal neuronal injury can be induced by
stroke, neurodegenerative disorders (Alzheimer’s disease)
37
classification of seizures according to the international league against epilepsy (ILAE)
1. onset or beginning 2. level of awareness 3. motor symptoms
38
3 major groups of seizures according to ILAE
1. generalized onset 2. focal onset 3. unknown onset
39
types of generalized seizures
1. tonic-clonic (grand mal) 2. absence (petite mal) 3. atonic epilepsy
40
most dramatic type of generalized seizure
tonic-clonic
