Male veterans with posttraumatic stress disorder (PTSD) (n = 11), including 6 with concurrent major depressive disorder (MDD), were compared to veterans with MDD alone (n = 18) and to 28 controls in their response to the dexamethasone suppression test (DST) and thyrotropin-releasing hormone (TRH) stimulation tests. We found higher levels of 4 PM serum cortisol and lower peak thyroid-stimulating hormone (TSH) response to TRH in the MDD patients than in either the PTSD patients or controls, in spite of equivalent levels of depression for MDD and PTSD. DST suppression (cortisol less than 5 mg/dl) occurred in 90% of control, 90% of PTSD, and 78% of MDD subjects, whereas TRH blunting (dTSHmax less than 7 microU/ml) occurred in 28% of control, 27% of PTSD, and 67% of MDD subjects. Rather than blunting, four PTSD patients (36%) and only 10% of the control and MDD subjects had high TSH responses (13-24 microU/ml), which may be linked to high noradrenergic activity, since subclinical hypothyroidism seemed unlikely.

The authors studied 227 inpatients from a large Veterans Administration Medical Center to evaluate whether alexithymia is associated with posttraumatic stress disorder (PTSD) and to assess the validity of the Minnesota Multiphasic Personality Inventory (MMPI) alexithymia scale. Three groups--a carefully diagnosed PTSD group (N = 76), an alcohol abuse group (N = 76), and a general psychiatric group (N = 75)--were given a battery of psychological tests, including the MMPI, the Millon Clinical Multiaxial Inventory, and the Beck Depression Inventory, along with several cognitive measures. PTSD veterans were also evaluated on psychophysiologic indices (including a stressor) and on their subjective ratings to these indices. Results showed that alexithymia was more characteristic of PTSD patients than of the other groups. Also, alexithymia was inversely related to heart rate. Alexithymia was not significantly correlated with the subjective experience of stressors. The authors discuss the importance of the construct of alexithymia among PTSD patients and recommend the use of the alexithymia scale for these patients. The independence of this measure from the psychophysiologic condition of hyperarousal and the subjective experience of this state were also addressed.

The present investigation examined the effectiveness of a cognitive behavioral treatment program designed for sexually abused children suffering post-traumatic stress disorder. Nineteen girls who suffered contact sexual abuse and met DSM-III-R criteria for post-traumatic stress disorder were included in the study. Subjects ranged in age from 3 to 16 years old. Structured interviews were conducted to assess the presence or absence of post-traumatic stress disorder symptoms before, during, and following the abuse. Additionally, parents completed the Child Behavior Checklist, and subjects at least 6 years of age were administered the Child Depression Inventory and the Spielberger State-Trait Anxiety Inventory at the initial evaluation and again approximately 2 to 3 weeks later before the initiation of treatment. The baseline data collected at these two points were compared, and no significant changes were found over time. The above measures were readministered following 12 treatment sessions. The results revealed significant improvements at post-treatment on all measures.

In addition to being effective in depressive disorders, monoamine oxidase inhibitors (MAOIs) have been shown to be effective in controlled studies of patient with panic disorder with agoraphobia, social phobia, atypical depression or mixed anxiety and depression, bulimia, posttraumatic stress disorder (PTSD) and borderline personality disorder. Uncontrolled case reports have noted MAOI efficacy in obsessive-compulsive disorder (OCD), trichotillomania, dysmorphophobia and avoidant personality disorder. Reversible inhibitors of MAO-A (RIMAs) appear safer than the classical irreversible MAOIs since they have less potential to increase blood pressure. They have not been studied as yet, however, in most of the conditions responsive to MAOIs. If RIMAs are found effective in these disorders, they would probably achieve wider use than MAOIs because they are safer and tend to cause fewer side effects.

We measured event-related brain potential (ERP) component amplitudes and heart rate (HR) to four intensities of randomly presented tones in two matched groups of drug-free male Vietnam veterans: 12 patients diagnosed with posttraumatic stress disorder (PTSD) and 6 normal combat veterans. Subjects were evaluated with structured diagnostic interviews and anxiety and depression rating scales. We found a significant group X intensity interaction for P2 peak amplitude at CZ. Subjects were classified as augmenters or reducers: positive P2 slopes as a function of stimulus intensity implying augmentation and negative slopes implying reduction. Nine of 12 PTSD subjects were reducers (sensitivity of 75%) and 5 of 6 normals were augmenters (specificity of 83.3%). By the third and fourth second following tone onset, the mean HR of PTSD subjects increased more than twice that of the normals. HR change scores were significantly responsive to the manipulation of stimulus intensity and to the difference between our two groups. P2 reduction differentiates Vietnam veterans with combat-related PTSD from combat veteran controls, and PTSD subjects are more autonomically arousable than their combat veteran peers.

Forty-four veterans with posttraumatic stress disorder (PTSD) from World War II and Vietnam were compared. The groups were comparable on many socioeconomic and combat measures and age at onset of PTSD. Vietnam veterans exhibited more severe PTSD symptoms, higher Hamilton depression scores, and higher scores on the hostility, psychoticism, and "additional symptom" Symptom Checklist-90 (SCL-90) scales. They also had more survivor guilt, impairment of work and interests, avoidance of reminders of trauma, detachment/estrangement from others, startle response, derealization, and suicidal tendencies. Differences were noted between the groups as to the nature of upsetting experiences. Vietnam veterans had a greater lifetime frequency of panic disorder and an earlier age of onset for alcoholism. In other respects, the two groups were diagnostically similar, with PTSD being related to the sequential emergence of psychiatric diagnoses in similar manner for World War II and Vietnam patients.

Psychological and psychiatric assessments were performed among 20 prisoner-of-war (POW) Korean-Conflict survivors. Results revealed extraordinary biological and psychological abuse with weight losses exceeding 35% of preservice weights and long-term cognitive, emotional, and behavioral sequelae. The full range of posttraumatic stress disorder symptoms was seen in 90% to 100% of the cases with high prevalence of co-morbidity, specifically mood (75%), other anxiety (45%), and alcohol abuse (20%) disorders. Documented by clinical investigators at POW release and now more than 30 years later, symptoms of apprehensiveness, confusion, detachment, and depression reflect the persistence of psychiatric morbidity over time.

Eight patients with combat-induced chronic posttraumatic stress disorder (PTSD) receiving long-term alprazolam therapy for anxiety or depression (maximum dose of 2-9 mg/day for 1-5 years) had alprazolam therapy withdrawn. Most of the patients underwent gradual medication withdrawal. All patients had a prior history of alcohol abuse or benzodiazepine dependence. During withdrawal, all patients had severe reactions including anxiety, sleep disturbance, rage reactions, hyperalertness, increased nightmares, and intrusive thoughts; and 6 of the 8 patients had homicidal ideation. As a result of this report, the authors suggest that the potential for severe withdrawal reactions, even with gradual tapering, should be considered before prescribing alprazolam therapy for this group of patients.

Amitriptyline hydrochloride was compared with placebo in 46 veterans with chronic posttraumatic stress disorder. Treatment continued up to 8 weeks, and efficacy was measured by five observer and two self-rated scales. Percent recovery rates were higher for amitriptyline than placebo on two measures. In patients who completed 4 weeks (n = 40), better outcome with amitriptyline was noted on the Hamilton depression scale only. In the group completing 8 weeks of treatment (n = 33), the drug was superior to placebo on Hamilton depression, Hamilton anxiety, Clinical Global Impression severity, and Impact of Event scales. There was no evidence for drug effects on the structured interview for posttraumatic stress disorder. Drug-placebo differences were greater in the presence of comorbidity in general, although recovery rates were uniformly low in the presence of major depression, panic disorder, and alcoholism. At the end of treatment, 64% of the amitriptyline and 72% of the placebo samples still met diagnostic criteria for posttraumatic stress disorder.

To evaluate the hypothalamic-pituitary-adrenal (HPA) axis in patients with posttraumatic stress disorder (PTSD), we measured adrenocorticotropin hormone (ACTH) and cortisol responses following administration of corticotropin-releasing hormone (CRH) in 8 combat veterans with chronic PTSD. The PTSD patients had a significantly lower ACTH response to CRH compared to a control group of normal volunteers. Blunted ACTH responses occurred in patients with PTSD alone, as well as those PTSD patients who also had major depression. The cortisol response, although reduced, was not significantly different from normal. The blunted ACTH response to CRH in PTSD patients is similar to that seen in other psychiatric disorders, such as depression, panic disorder, and anorexia nervosa.
