The current study examined the effects of age and gender on emotional and nonemotional expression using an experimental word list generation (WLG) task (also referred to in the literature as verbal fluency) from the New York Emotion Battery (Borod, Welkowitz, & Obler, 1992). Subjects were 28 young ( M = 29.6 years), 28 middle-aged (M = 49.8 years), and 28 older (M = 69.9 years) healthy adults. The WLG task consists of 8 emotional (E; 3 positive and 5 negative) and 8 nonemotional (NE) categories. We developed and present here a detailed word error-type analysis that was used to evaluate the lexical output. In this study, both quantitative (amount of output and error-types) and qualitative (accuracy and intensity) analyses were used. While subjects produced more nonemotional than emotional words and more positive than negative words, the amount of error-free output and the number of errors did not change with age. An age group by error-type interaction indicated that older adults, especially men, produced more repetition errors than younger adults. The error-free output was subsequently rated for accuracy and emotional intensity. The rating data revealed that older women's overall lexical output was less accurate than that produced by younger women. Also, negative emotional words were more accurate and intense than positive emotional words. The procedures described here have implications for research assessing word list generation and emotional expression in clinical populations.

P103 Background: Hemicraniectomy and durotomy has been shown to be a promising treatment for malignant MCA infarction, but has not been evaluated for cerebral hemorrhage. Methods: We analyzed the clinical course and outcome of 15 patients treated with decompressive surgery for space-occupying cerebral hematomas between 9/98 and 6/00. All patients were treated with duroplasty and either hemicraniectomy (n=13) or a “floating” bone flap (n=2); in some patients, hematoma (n=5) and subdural clot (n=2) evacuation was also performed. Outcomes were assessed by telephone interview using the modified Rankin scale (mRS). Results: Mean age was 49 years (range 33–66); 8 were women; the lesion was left-sided in 7. Hematoma formation was related to spontaneous aneurysmal rupture (n=7), intra-operative aneurysmal rupture (n=3), hypertensive intracerebral hemorrhage (n= 3), and hemorrhagic infarction (n=2). Surgery was peformed <24 hours after onset in 5 patients, between 24–48 hours in 6, and between 3–5 days in 4. On the day of surgery, mean hematoma volume was 63 ml (range 6–216 ml), mean GCS was 6.3 (range 4–10), and mean NIHSS was 22 (range 13–28); 5 patients had clinical herniation signs. Postoperative CT scans showed significant reductions in both mean septal shift (from 10.3 to 6.1 mm) and pineal shift (from 6.4 to 3.5 mm) (both P<.02). Eighty percent (12/15) of patients survived to discharge, and one died after discharge. After a mean follow up of 5.7 months (range 1–13), one survivor (9%) had no disability (mRS 0–1), four (36%) had slight or moderate disability (mRS 2–3), and six (54%) had moderate or severe disability (mRS 4–5). Conclusion: Duroplasty and hemicraniectomy, with or without concurrent hematoma evacuation, may improve survival and recovery in comatose patients with large aneurysmal, hypertensive, or infarct-related cerebral hemorrhages.
