|
[31] |
12 combat PTSD veterans 6 normal controls |
Four tones intensity paradigm |
No difference in N1 amplitude |
|
|
|||
|
[17] |
20 Israeli combat veterans with PTSD 20 without PTSD |
Visual oddball, trauma related non-related neutral stimuli |
Combat-related pictures elicited enhanced N1 amplitude in PTSD group. Prolonged N1 latencies and reaction times to target stimuli in PTSD patients. |
|
|
|||
|
[56] |
16 medicated, 9 un-medicated PTSD 10 healthy veterans |
Auditory three-tone oddball |
Longer N100 latencies in un-medicated PTSD patients compared to the medicated PTSD and healthy controls. |
|
|
|||
|
[51] |
11 prisoners of war |
Checkerboard reversal |
Larger N75 amplitudes |
|
|
|||
|
[39] |
11 PTSD survivors of a ship fire 9 psychiatric controls from the same ship |
Auditory word and non-word oddball |
Increased N1 latency to standard tones; Larger amplitude to emotionally meaningful words. |
|
|
|||
|
[25] |
13 females with sexual assault PTSD 16 healthy controls |
Auditory oddball |
No difference in N100 amplitude and latency |
|
|
|||
|
[28] |
17 civil PTSD 17 healthy controls |
Auditory oddball |
No difference in N100 amplitude or latency |
|
|
|||
|
[30] |
36 civil PTSD 20 healthy 10 depressed 8 alcoholics |
2000-Hz tone presented in increasing intensities |
Increased N100 amplitudes |
|
|
|||
|
[38] |
15 civil PTSD 15 controls |
Visual presentation of angry alternating with neutral faces |
Larger N110 to the angry compared to the neutral faces in the control group. Smaller and later N100 in PTSD subjects. |
|
|
|||
|
[35] |
10 civil PTSD 10 controls |
Auditory oddball |
Larger N100 amplitude |
|
|
|||
|
[42] |
19 PTSD 99 Alcohol dependence 16 personality disorder 25 anxiety or mood disorder |
Visual presentation of happy, sad, and neutral faces |
Larger N1 amplitudes to sad stimuli in frontotemporal leads in PTSD patients. |
|
|
|||
|
[57] |
16 civil PTSD 16 schizophrenia 16 control subjects |
Auditory Oddball |
No difference in N1 amplitude and latency |
|
|
|||
|
[36] |
14 PTSD [mixed etiologies] 12 controls |
Auditory Oddball |
