Abstract
OBJECTIVES To explore associations among cognition, frailty, and obesity in older adults. DESIGN Descriptive, secondary analysis of baseline data from two related lifestyle intervention trials. SETTING Clinical study open to civilian population through the Center for Translational Research on Inflammatory Diseases at the Veterans Affairs Medical Center in Houston, TX. PARTICIPANTS One hundred eight community-dwelling adults with obesity, aged 65 or older, recruited consecutively from two lifestyle intervention trials. MEASUREMENTS Cognition was assessed using Composite Age-Adjusted Scale Score from the National Institutes of Health Toolbox Cognition Battery: Obesity was assessed by body mass index (BMI) and also by truncal fat mas via dual energy x-ray absorptiometry. Frailty was assessed using the Physical Performance Test. RESULTS A significant linear regression model for cognition revealed frailty as the strongest predictor, followed by sex, and then truncal fat (R2=0.340, p<0.001). CONCLUSION Cognition among community-dwelling older adults with obese BMI may worsen with greater truncal fat mass. Frailty appears to be an important predictor of cognitive performance in this population.

Abstract
Abstract
Introduction
Neuroprotection, early diagnosis, and behavioral intervention are national priorities for dementia research. Sleep duration is emerging as an important potential remediable risk factor. In this study, we examined the total sleep time derived from overnight polysomnography (PSG) studies in veterans with a current dementia diagnosis at the time of PSG study (dementia), future diagnosis of dementia following the PSG study (incipient dementia), and no diagnosis of dementia at any time point (no dementia) over a 19-year period.
Methods
We identified 69,847 PSG sleep studies using CPT code 95810 and all-cause dementia diagnosis using ICD 9/10 codes (e.g., F03.90) from 2000-19 in the US Department of Veteran Affairs (VA) national database. To be included patients must have ≥ 1 VA visits in 12 months leading up to PSG. Dementia diagnosis must be documented on two separate visits between 12 months prior to 6 months following PSG for current dementia group and anytime after the PSG for incipient dementia. We used natural language processing to extract TST values from the patient free-text notes. Analysis of variance was used to compare PSG TST of the three groups.
Results
Patients had a mean age of 55.4±13.8 at the time of PSG study, 91.5% were male, and 64% were Caucasian. TST of dementia patients (N=1,031) was m=257±110m (d=0.33, p<.05), incipient dementia (N=1,875) was m=253±116m (d=0.35, p<.05) versus no dementia (61,871) m=292±104mins.
Conclusion
Patients with a diagnosis of dementia at the time of PSG study and patients that went on to receive a diagnosis following their PSG study had a significantly lower total sleep time compared to patients that have never received a dementia diagnosis. This is an important study that compares sleep duration during overnight PSG studies and dementia diagnosis across 19 years in the largest integrated healthcare system in the US.

Abstract
Abstract
Introduction
Neuroprotection, early diagnosis, and behavioral intervention are national priorities for dementia research. Sleep duration is emerging as an important potential remediable risk factor. In this study, we examined whether total sleep time (TST) derived from attended overnight polysomnography (PSG) studies is associated with an increased prevalence of dementia diagnosis and determined the optimal cut-point.
Methods
We identified 69,847 PSG sleep studies using CPT code 95810 from 2000-19 in the US Department of Veteran Affairs (VA) national database of patient care. We used natural language processing to verify PSG reports and extract TST values from the patient free-text notes. We examined a TST of 240-420 minutes in 10-minute increments using a run chart (time series) approach to determine the optimal cut-point for determining greater odds of dementia.
Results
Patients had a mean age of 55.4±13.8, 91.5% were male, and 64% were Caucasian. PSG studies revealed a mean TST of 310.6±79.5 minutes. The run chart time series analysis revealing < 360 minutes being the optimal cut-point for increased odds of dementia (OR: 1.64, 95% CI: 1.36-1.99, p<.05).
Conclusion
Lower TST predicted higher prevalence of dementia diagnosis. TST of 360 minutes may serve as the optimal cut-point to determine greater odds of dementia. This is an important study examining PSG sleep duration and the prevalence of dementia across 19 years in the largest integrated healthcare system in the US. TST may function as a potential biomarker for developing dementia.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) affects 14 to 20 million Americans and is associated with increased prevalence of affective disorders, contributing significantly to disability. This study compared cognitive behavioral therapy (CBT) group treatment for anxiety and depression with COPD education for COPD patients with moderate-to-severe anxiety and/or depressive symptoms. METHOD A randomized controlled trial (RCT) was conducted between 11 July 2002 and 30 April 2005 at the Michael E. DeBakey VA Medical Center, Houston, TX. Participants were 238 patients treated for COPD the year before, with forced expiratory value in 1 second (FEV)1/forced vital capacity (FVC)<70% and FEV1<70% predicted, and symptoms of moderate anxiety and/or moderate depression, who were being treated by a primary care provider or pulmonologist. Participants attended eight sessions of CBT or COPD education. Assessments were at baseline, at 4 and 8 weeks, and 4, 8 and 12 months. Primary outcomes were disease-specific and generic quality of life (QoL) [Chronic Respiratory Questionnaire (CRQ) and Medical Outcomes Survey Short Form-36 (SF-36) respectively]. Secondary outcomes were anxiety [Beck Anxiety Inventory (BAI)], depressive symptoms [Beck Depression Inventory-II (BDI-II)], 6-minute walk distance (6MWD) and use of health services. RESULTS Both treatments significantly improved QoL, anxiety and depression (p<0.005) over 8 weeks; the rate of change did not differ between groups. Improvements were maintained with no significant change during follow-up. Ratios of post- to pretreatment use of health services were equal to 1 for both groups. CONCLUSIONS CBT group treatment and COPD education can achieve sustainable improvements in QoL for COPD patients experiencing moderate-to-severe symptoms of depression or anxiety.

Abstract
For patients with chronic hepatitis C virus, certain psychiatric disorders are contraindications for antiviral therapy with interferon-alpha (IFN). Although these conditions delay a significant portion of patients from beginning therapy, no one has yet portrayed the views of these patients. A qualitative analysis, drawing upon semi-structured interviews, was developed to generate hypotheses regarding patient views of the treatment disposition process, and to generate strategies for increasing the portion of treatment-eligible patients. Two focus groups were conducted: one for patients delayed from treatment due to current or recent depression, and one for patients delayed due to current or recent alcohol use. A grounded theory analysis of the interview data were conducted. Patients were generally satisfied with the decision-making process, based largely on education from, and trust in, physicians. Upon learning their diagnosis, patients reported making healthy behaviour changes regarding alcohol, diet, exercise and herbal remedies. Some patients reported that requiring a period of alcohol abstinence was excessive, as they believed that they could discontinue alcohol use immediately, if so instructed by a physician. Patients seemed to over-interpret the likelihood of suicide during interferon-alpha (IFN) therapy. Current or recent psychiatric morbidity delays many patients from beginning interferon therapy. Nonetheless, this may be an optimal time for physicians to encourage healthy behaviours including abstinence from alcohol. Also, physicians may need to extensively assess the use of herbal remedies by patients. To help patients make judgments about beginning therapy, physicians should focus upon risk communication regarding the likelihood of suicide on therapy with interferon.

Abstract
Information regarding older adult emergency center (EC) patient characteristics remains limited, despite its increasing importance in health care delivery systems. This retrospective study encompasses all EC visits over an eight-year period (n = 825,682) to a large urban county hospital. Only participants with a primary psychiatric diagnosis were examined, and included a total of 53,894 adults, 18-64 years old and 1,478 adults, > or =65 years old. Despite an increasing aging population, EC visits for older adults with psychiatric disorders did not increase over time. Within the older adult sample, cognitive, psychotic, and bipolar disorders were associated with higher rates of admission to the hospital, while substance use, depressive, and anxiety disorders were associated with lower numbers of inpatient admissions. African-Americans were over-represented in the EC and admitted to the hospital at higher rates, compared to other ethnic groups. Caucasian patients were the group most frequently diagnosed with a substance use disorder. In conclusion, differences in race, and diagnosis support the idea that such variables directly relate to utilization rates, presentation, and disposition within the EC.

Abstract
BACKGROUND The frequency and determinants of receipt of antiviral therapy once a diagnosis of a mood disorder is established in hepatitis C virus (HCV)-infected patients remains unknown. AIM To examine the incidence and determinants of receiving antiviral therapy in HCV-infected veterans with abnormal scores of Zung Self-Rating Depression Scale (SDS). METHODS We systematically evaluated the presence of psychiatric disorders among HCV-infected patients with initial referral between September 2000 and May 2002. We reviewed medical records, obtained history, and administered Zung SDS to evaluate for depressive symptoms. Patients with psychiatric disorders were referred for psychiatric evaluation. The primary outcome was the receipt of antiviral therapy during and after the initial evaluation up to December 1, 2003. The association between SDS scores and receipt of antiviral therapy was examined in a multivariate Cox proportional hazards regression. RESULTS A total of 424 patients completed a Zung SDS. The scores were normal in only 43% of all patients, and were impaired mildly in 25%, moderately in 23%, and severely in 9%. Zung SDS scores were significantly higher in patients who served during the Vietnam War era, participated in combat, or had lower albumin levels. At the end of the first visit, 180 (42%) had psychiatric disorders. An abnormal Zung score (>55) was the only reason for referral to psychiatry in 83 of 180 patients; and in those 78 (94%) a formal psychiatric evaluation confirmed depressive disorder. Psychiatric disorders were the sole contraindication to therapy in 145 (34%) patients in whom eligibility for antiviral therapy was achieved in 42 (29%) during a mean follow-up duration of 27 months. CONCLUSIONS Approximately one-quarter of patients with psychiatric disorders may become eligible for antiviral therapy following subsequent management of these disorders. The Zung self-screening test is an easy, valid method for detecting mood disorders in HCV-infected veterans.

Abstract
This study examined psychological predictors of Global Assessment of Functioning Scale scores (GAF) at intake and at discharge for geropsychiatric inpatients. A total of 301 predominantly male geropsychiatric inpatients were recruited from the Houston Veterans Affairs Medical Center. Path analysis was used to test a model proposing causal paths of psychological predictors (cognitive status, depression, agitation, general psychiatric status) to GAF scores on admission and discharge. At admission, all four psychological predictors had positive paths to the admission GAF scale scores but at discharge, only two (i.e., cognitive status and general psychiatric status) of the four psychological predictors had positive paths to the discharge GAF scale scores. The admission GAF scale scores also had a positive path to the discharge GAF scale scores. The overall functioning level of geropsychiatric inpatients may be predicted by measures which assess overall cognitive status and general psychiatric functioning during hospitalization. Results prompt consideration of a modified global scale specifically reflecting an older adult's activities during this period of life.

Abstract
Delirium is a disturbance of consciousness, cognition and perception that occurs frequently in medically ill patients. Although it is associated with increased morbidity and mortality, it is often not recognised and treated by physicians. Predisposing factors are believed to have multiplicative effects and include dementia, advanced age and male gender. Recently developed models allow for the estimation of the risk of developing delirium during a hospitalisation, based on predisposing factors and acute additional stressors. Although it has been shown to be efficacious, the prevention of delirium is underutilised. Prevention consists of aggressive management of known risk factors and early detection. Limited data exist to support specific pharmacological interventions for its treatment. In this article, the avail-able published literature regarding the prevention and treatment of delirium is systematically reviewed.

Abstract
This cross-sectional measurement study demonstrates a technique for combining information from several aggression scales into one aggression score using latent variable modeling. Participants included male patients (n = 49) with a DSM-IV diagnosis of dementia at The Veterans Affairs Medical Center Outpatient Geriatric Psychiatry Clinic. Data from seven aggression scales were used to indicate the latent aggression variable. Results provided evidence that a unidimensional latent variable model of aggression adequately represented the data. Reliability of the aggression latent variable was estimated as 0.90, whereas reliability of the separate scales estimated with this sample were less than 0.84. Our findings suggest that combining multiple scales into one aggression score using latent variable modeling results in comprehensive and reliable aggression scores that offer researchers several advantages over current methods for measuring aggression.

Abstract
The relationships between reminiscence functions and attachment styles; reminiscence and personality factors; and attachment and personality were examined in forty patients attending a geropsychiatric outpatient clinic. They were administered the Reminiscence Functions Scale, NEO-FFI, and the Relationship Questionnaire. Compared with insecurely attached older patients, securely attached older patients score higher on the teach/inform reminiscence function. Consistent with prior research, relationships were found between the extraversion personality factor and conversation reminiscence; and between the openness personality factor and both identity and problem-solving reminiscence functions.

Abstract
BACKGROUND We hypothesized that compared to an educational intervention, a single 2 h session of cognitive behavioural therapy (CBT), with 6-week follow-up, would reduce anxiety and depression, improve physical and mental functioning, and lead to a better quality of life and greater satisfaction with treatment in older patients with chronic obstructive pulmonary disease (COPD). METHODS Fifty-six subjects were recruited from a large, urban, academically affiliated Veterans Affairs (VA) Hospital, a non-profit private hospital, and a local newspaper, for a single blind randomized controlled clinical trial. One 2 h session of group CBT was designed to reduce symptoms of anxiety, with specific components including relaxation training, cognitive interventions, and graduated practice, followed by homework and weekly calls for 6 weeks. This was compared to a group that received 2 h of COPD education, followed by weekly calls. Pre- and post-intervention subjects in both groups were administered SF-36, Geriatric Depression Scale, Beck Anxiety Inventory, 6 min walk test, and the FEV-1. Following the intervention, both groups completed the Client Satisfaction Questionnaire. RESULTS When compared with a group that received education about COPD, 2 h CBT group showed decreased depression and anxiety. Contrary to our hypothesis, despite the decrease in depression and anxiety, there was no change in the physical functioning of the patients. CONCLUSIONS Twenty to 40% of patients with COPD have high levels of anxiety and depression. Our study finds that as little as 2 h of CBT administered in a group setting is able to reduce these anxious and depressive symptoms.

Abstract
As many World War II and Korean Conflict veterans suffering from posttraumatic stress disorder (PTSD) grow older, increasing numbers will be diagnosed with dementia. We retrospectively analyzed patients with dementia, comparing the behavioral disturbances of those with PTSD to those without PTSD. We hypothesized that due to the additive effect of the neurobiological and behavioral changes associated with PTSD and dementia, the dementia with PTSD group would show more agitation and disinhibition than the dementia without PTSD group. Sixteen patients with diagnoses of dementia and PTSD were matched on age and Mini-Mental States Examination (MMSE) scores to 16 patients with dementia without PTSD. Demographic characteristics, co-morbid diagnoses, global Assessment of Functioning (GAF), Cohen-Mansfield Agitation Inventory (CMAI), and paranoid items of Brief Psychiatric Rating Scale (BPRS) and Positive and Negative Syndrome Scale for Schizophrenia (PANSS) were assessed. The patients with diagnoses of dementia with PTSD did not differ significantly in their clinical presentation, hospital course, and condition at discharge from patients with dementia without PTSD. Chi-square analysis showed that significantly more subjects in the PTSD group were prescribed anti-depressants compared to the non-PTSD group. Interestingly, within the PTSD group, the subgroup of patients who were former prisoners of war had a significantly higher mean score for paranoia and significantly less verbal agitation. This pilot study reveals that a diagnosis of PTSD alone is not sufficient to influence behavior in veterans with dementia; however, we also present provocative results that patients with more severe trauma (POW) do have changes in their behavior.

Abstract
This study examined the outcomes associated with shortening hospital stays for geriatric inpatients with dementia at a Veterans Administration medical center. Thirty-three patients who were admitted after January 1997, when the hospital decided to reduce patients' lengths of stay, were matched with 33 patients who were admitted before January 1997. Despite significant differences in lengths of stay, no differences were found between the groups on measures of agitation or overall functioning. Despite significantly shorter stays since January 1997, the results of our study indicate that the cognitive and emotional status of patients discharged since that time are equivalent to those of patients discharged after longer hospital stays.

Abstract
The objective of this study was to compare differences in behavioral, psychiatric, and cognitive status among geropsychiatric inpatients with Alzheimer's, vascular, alcohol-induced, and mixed dementia. Participants included 150 patients with dementia consecutively admitted to an acute geropsychiatric inpatient unit. Measures included the Mini-Mental State Examination, Cohen-Mansfield Agitation Inventory, Cumulative Illness Rating Scale, Basic and Independent Activities of Daily Living, Positive and Negative Syndrome Scale for Schizophrenia, and the Initiation/Perseveration subscale of the Dementia Rating Scale. No significant differences existed in the character or severity of agitation among patients with Alzheimer's, vascular, alcohol-related and mixed dementia. Interestingly, patients with vascular dementia compared to patients with other dementias admitted for behavioral disturbances were less cognitively impaired and more medically burdened.

Abstract
The authors determined the prevalence and demographic features of drug use disorders in a database of 565 veteran geropsychiatric inpatients. Twenty-four patients (4%) were diagnosed with nonalcoholic substance use disorders, including 18 (3%) with prescription drug use disorders and 6 (1%) with illegal drug use disorders. The patients diagnosed with prescription drug use disorders were predominantly Caucasian, whereas those diagnosed with illegal substance use disorders were predominantly African American. No other significant demographic differences were noted. Nonalcohol substance use disorders represent an unappreciated problem in psychiatrically hospitalized older adults, with illegal substance use disorders making up a larger than expected proportion of this group.

Abstract
The atypical antipsychotics are gradually becoming the mainstay of treatment for psychosis in the elderly. The present study examines the effectiveness and tolerability of risperidone and olanzapine treatment in 34 matched male patients admitted to a VA Medical Center geriatric inpatient unit. The Positive and Negative Syndrome Scale for Schizophrenia (PANSS), the Cohen-Mansfield Agitation Inventory (CMAI), the Rating Scale for Side-Effects, the Extra-Pyramidal Rating Scale, and the Mini-Mental State Examination were administered at admission and discharge. T-tests at admission and discharge across groups indicate that the patients as a whole were performing significantly better following their stay on the CMAI (t(30)=4.31, p=0.000), the GAF (t(31)=9.73, p=0.000), the PANSS total score (t(29)=3.82, p=0.001), and the positive symptom portion of the PANSS (t(28)=4.29, p=0.000). No significant differences were detected between the two groups with regard to length of hospitalization, or reduction in scores on the PANSS, or CMAI, however the daily cost of risperidone was 1/3 as much as olanzapine (p=0.00). The two treatments were comparable in the elderly men evaluated in this study.

Abstract
The authors examine the less-studied components of patients' autonomous decision making, or decisional autonomy, in the light of current research in psychiatry and neuropsychology and developments in the construct of informed consent. The three components of decisional autonomy-understanding, intentionality, and noncontrol or voluntariness-are related to clinical constructs in psychiatry and neuropsychology, in particular to executive control functions. The authors review studies that examine deficits in prefrontal cerebral function in schizophrenia, depression, and some anxiety disorders that are related to intentionality and voluntariness. Assessment of decisional autonomy should encompass evaluation of impaired intentionality and voluntariness, not simply impaired understanding. The main response to finding such impairments should be to provide treatment to ameliorate them. New strategies for psychiatric care should be developed to address the clinical challenges of an increasingly complex view of decisional autonomy.

Abstract
The authors examined the relationship between functional status and comorbid anxiety and depression and the relationship between utilization of health care resources and psychopathology in elderly patients with chronic obstructive pulmonary disease (COPD). Elderly male veterans (N = 43) with COPD completed anxiety, depression, and functional status measures. The authors constructed regression models to explore the contribution of COPD severity, medical burden, depression, and anxiety to the dependent variables of functional impairment and health care utilization. Anxiety and depression contributed significantly to the overall variance in functional status of COPD patients, over and above medical burden and COPD severity, as measured by the 8 scales of the Medical Outcomes Study (MOS) 36-item Short Form Health Survey. Surprisingly, medical burden and COPD severity did not contribute significantly to overall variance in functional status. Few patients were receiving any treatment for anxiety or depression.

Abstract
The literature on pain in dementia patients is reviewed. A summary of methods for assessment of pain in demented elderly persons and an examination of studies that used such methods are included. In addition, literature theorizing a decrease in affective pain in this population is discussed; management of pain in such patients is not discussed extensively. Research reveals 3 major findings: (a) a moderate decrease in pain occurs in cognitively impaired elderly persons, (b) communicative dementia patients' reports of pain tend to be as valid as those of cognitively intact patients, and (c) assessment scales developed thus far for noncommunicative patients require improvement in accuracy and facility. Many questions about pain in dementia patients remain, and the continued development of valid pain assessment techniques is a necessity.

Abstract
This cross-sectional study explored age-related differences in the frequency of diagnosis of personality disorder (PD) among 790 veterans admitted to a psychiatric inpatient unit across three age groups: 20-39, 40-59, and 60+. Older adults obtained a lower frequency (55.4%) of PD diagnosis than middle-aged adults (69.0%), who in turn obtained a lower frequency of PD diagnosis than young adults (75.9%). Older adults and middle-aged adults were less likely to receive a diagnosis of Borderline PD than young adults. Older adults were also less likely to receive a diagnosis of Mixed PD than young adults, but received significantly more diagnoses of Narcissistic PD than young adults. Patients diagnosed with PD had higher rates of psychiatric hospitalization than those with no diagnosis of PD. Older adults and middle-aged adults with PD had significantly fewer psychiatric hospitalizations than young adults with PD, whereas there were no age-related differences in the frequency of medical hospitalizations. These findings are consistent with research suggesting an overall softening of PD features with age, particularly those characteristic of the 'dramatic-erratic', Cluster B types.

Abstract
Variables associated with successful completion of guardianship applications for elderly patients were identified. Thirteen patients for whom applications were approved were compared with 26 whose applications did not reach the court. Patients for whom the process was successful scored significantly higher on the anergia-depression subscale of the Brief Psychiatric Rating Scale and had significantly more medical conditions in the past year. A survey of next of kin revealed that the process had a much better chance of success when the unit social worker made the guardianship recommendation and when family members were given more information about the taxing and time-consuming process of obtaining guardianship.

Abstract
The authors identify the clinical and ethical implications of impaired executive control functions for patient autonomy. Executive control functions are processes that orchestrate relatively simple ideas, movements, or actions into complex goal-directed behavior, and impairments in these functions are becoming more common as the population ages. The authors examine difficulties that individuals with impaired executive control functions may have in making treatment decisions and describe a practical, ethically justified framework for making treatment decisions for patients with impairments in these functions. Three components of autonomy are identified-intentionality, understanding, and voluntariness. Intentionality and voluntariness are especially affected by impaired executive control functions. Impairments of these aspects of autonomy may often be overlooked when only traditional mental status examinations are employed, with adverse consequences for the health of patients wrongly thought to possess intact ability to make and carry out plans of care. Two case vignettes illustrate the complexities faced by clinicians intervening with patients who have deficits in decision-making capacity caused by impaired executive control functions.

Abstract
The purpose of this study was to identify a combination of variables that could predict rehospitalization among a sample of 150 geropsychiatric inpatients. Logistic regression analyses testing a modified model identified risk factors for geropsychiatric rehospitalization and correctly classified approximately 80% of inpatients who were rehospitalized for subsequent treatment. Patients' psychiatric diagnosis (mood or schizophrenic disorder), poor general psychiatric functioning, depressive and agitated behavior at discharge, little or no supervision in living arrangements following discharge, limited social support, change in the social support system preceding hospitalization, and maladaptive family functioning could significantly predict geropsychiatric rehospitalization. The strongest independent predictor was maladaptive family functioning.

Abstract
OBJECTIVE Cross-cultural differences in treatment and diagnosis exist in several psychiatric disorders. This study examines phenomenological and treatment differences between Caucasian and African-American patients presenting to a geropsychiatric unit for treatment of behavioral disturbances associated with dementia. METHODS One hundred and forty-one Caucasian patients were compared to 56 African-American patients consecutively admitted to a VA geropsychiatric inpatient unit. At admission, differences in behavior disturbances between the two groups were examined using the Mini-Mental State Examination (MMSE), Cohen-Mansfield Agitation Inventory (CMAI), Hamilton Rating Scale for Depression (HAM-D), Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale for Schizophrenia (PANSS). Differences in treatment were assessed by comparing medication types and doses between the two groups. RESULTS AND CONCLUSION Results showed that Caucasian and African-American patients with dementia and behavioral disturbances presented and responded similarly to like treatment on an inpatient geropsychiatric unit. The similarity between the two groups may be explained by the multi-ethnic make-up of the interdisciplinary treatment team and by the use of standardized scales to measure symptomatology and response.

Abstract
BACKGROUND Specific behavioral disturbances in dementia may be associated with underlying disorders such as the presence of psychosis and depression. The objective of this study was to examine the association of depression and psychosis with behavioral disturbances in geropsychiatric inpatients with dementia. METHODS All admissions between October 1993 and May 1995 were reviewed to identify those patients admitted to the Houston Veterans Affairs Geropsychiatry Unit with a diagnosis of dementia; 208 patients were included in the study. Hierarchical regression models were constructed to explore the contribution of depressive and psychotic symptoms, and depression and psychosis diagnoses to Cohen-Mansfield Agitation Inventory (CMAI) scores. RESULTS Both depression and psychotic symptoms were significantly and positively correlated with behavioral disturbances. Psychotic symptoms were associated with aggressive behavioral symptoms, and depressive symptoms were associated with constant requests for help, complaining, and negativism. Dementia severity accounted for significant variance in CMAI scores and was positively associated with behavioral disturbance; though disorder symptoms accounted for more behavioral disturbance variance than did depressive symptoms. CONCLUSIONS Both depressive and psychotic symptoms were associated with overall behavioral disturbances in patients with dementia. Psychotic symptoms and depressive symptoms were associated with different types of behavioral disturbances. Our findings support the contention that underlying depression or psychosis may partially account for different behavioral disturbances and that not all behavioral disturbances should be globally labeled "agitation." Future studies should address symptom-specific treatment of behaviorally disturbed patients.

Abstract
This article describes an ethics case conference on a multidisciplinary geropsychiatric service, and its unique clinical, training, and research benefits. We describe the structure of the conference, the major topics addressed, the perceived advantages, and the research implications. We conclude that the care of older patients, the education of students and trainees interested in aging issues, and cutting-edge geriatric research are all advanced by such a conference.

Abstract
The authors compared patients in a geropsychiatric unit who showed marked cognitive decline during hospitalization with those who did not. Patients who declined in cognitive function were older, were more likely to have a diagnosis of dementia, and were more anergic on admission. These patients were also discharged to more restrictive living environments. The subgroup of demented patients who declined in cognitive function were also older and improved less on anxiety and depression.

The relationship between patient, informant, social worker, and consensus diagnoses of personality disorder in elderly depressed inpatients. Am J Geriatr Psychiatry 1998; 6:136-44.

Abstract
Two psychiatrists simultaneously administered the Personality Assessment Form (PAF) to 20 depressed geropsychiatric inpatients and to 20 of their relatives (informants). A social worker also completed PAF ratings, and a consensus conference independently assigned an Axis II diagnosis. For patient interviews, categorical and dimensional interrater reliability indices for cluster and total personality disorders (PDs) were generally marginal. For informant interviews, categorical interrater reliability indices for cluster and total PDs were also marginal, but dimensional reliability was high. Consistent with previous research, agreement between categorical scores yielded by the four assessment methods was poor, but agreement between dimensional scores was generally better. It appears that patients, family members, and staff maintain different perspectives on patients' personality that, if overlapping, may provide useful diagnostic data.

Abstract
This study investigated the correlates of change in behavioral disturbance in geropsychiatric inpatients with dementia. It was hypothesized that improvement in specific psychiatric symptoms, such as psychosis and depression, contribute to the improvement of specific behavioral disturbances. All admissions between October 1993 and May 1995 were reviewed to identify those patients admitted to the Houston VA geropsychiatry unit with a diagnosis of dementia; 233 patients were included in the study. Improvement in behavioral disturbance symptoms was associated with decreases in depression, thought disorder, and hostility. However, the relative importance of depressive and psychotic symptoms varied depending upon the type of behavioral disturbance examined. These results may support a focused approach employing therapies specific to the type of behavioral disturbance.

Abstract
In order to define the contributions of cognitive impairment, medical burden, and psychopathology to the functional status of geriatric psychiatric patients, a forward-looking, retrospective study of 106 consecutive admissions to a geriatric psychiatric unit at the Houston Veterans Affairs Medical Center Hospital was done. It was found that psychopathology and cognitive status, but not medical burden, contributed to the variance in functional status of geriatric psychiatric inpatients for both admission scores and for changes in scores during hospitalization. Improvements in cognitive state and psychopathology were associated with improvements in functional status during hospitalization.

Abstract
Behavioral disturbances are commonly encountered in elderly demented patients. The records of all patients admitted to a geropsychiatric inpatient unit within a 2-year period who had a primary diagnosis of dementia and an accompanying behavioral disturbance treated with divalproex sodium were reviewed. Of the 13 patients identified, all tolerated divalproex sodium without significant side-effects. General psychiatric symptoms, overall agitation, physical aggression and non-aggressive physical agitation decreased significantly, but verbal agitation did not. Divalproex sodium is well tolerated and may be effective in ameliorating certain behavioral disturbances in elderly demented patients with agitation.

Abstract
The authors compared the presentation and course of major depression in male geriatric inpatients with and without a diagnosis of dementia. Of 326 consecutive admissions to an inpatient geropsychiatry unit, 22 (7%) had a diagnosis of major depression without dementia, 35 (11%) had major depression with dementia. Both groups presented with similar types and severity of depressive symptoms, which improved substantially with treatment in both groups, as measured by Hamilton Depression Rating Scale scores. In addition, agitation, psychiatric, and side-effects symptoms decreased significantly in both groups. Our naturalistic results suggest the clinical value of intensive treatment of depressive symptoms in elderly demented patients, whether or not they meet the criteria for major depressive episode.

Abstract
OBJECTIVE The tolerability of clonazepam in geropsychiatric inpatients was examined in patients with and without a diagnosis of dementia. DESIGN Forward-looking retrospective study comprising consecutive patients placed on clonazepam. SETTING A geropsychiatry unit of a large Veterans Affairs Medical Center. PATIENTS All geropsychiatry inpatients placed on clonazepam over a 21-month period of time. MEASURE Mini-Mental State Examination, Brief Psychiatric Rating Scale, Cohen-Mansfield Agitation Inventory and the Rating Scale for Side Effects were performed at admission and discharge as part of an ongoing database. RESULTS Twenty-four geropsychiatric inpatients were treated with clonazepam (mean dose of 1.2 mg for a minimum of 2 weeks) during the 21 months studies. About one half of the patients had a primary diagnosis of dementia and the remainder had a diagnosis of an affective or psychotic disorder. Two of these patients were discontinued because they had responded to the acute need for clonazepam and a third patient was discontinued because of the development of sedation and confusion. For the remaining 21 patients, scores improved significantly on the Brief Psychiatric Rating Scale (p = 0.017), the Cohen-Mansfield Agitation Inventory (p = 0.011), the Rating Scale for Side Effects (0.004) and the Global Assessment of Functioning (p < 0.000), with no differences in amount of improvement between demented and non-demented patient groups. Scores on the Mini-Mental State Examination remained unchanged. CONCLUSIONS Clonazepam shows promise as a benzodiazepine with good tolerability in the elderly.

Abstract
The authors determined the outcome of geropsychiatric hospitalization for 73 very low-functioning demented patients (GAF score < 21). General psychiatric symptoms, depression, and agitation decreased significantly, and mean GAF scores increased significantly, with no significant change in cognitive function. Psychiatric hospitalization can meaningfully improve function and quality of life even in this very impaired population. Despite these improvements many patients are discharged to more restrictive settings.

Abstract
The authors examined the effect of hospitalization on cognitive and behavioral symptoms in delirious elderly patients with and without dementia. Forty-four (13%) of the patients admitted to a Veterans Affairs Medical Center geropsychiatric unit were diagnosed with delirium and were administered the Mini-Mental State Examination, the Hamilton Depression Rating Scale, the Brief Psychiatric Rating Scale (BPRS), the Rating Scale for Side Effects, and the Cohen-Mansfield Agitation Inventory. The total sample significantly improved on all measures. When patients with delirium were divided into subgroups with and without dementia, both subgroups improved similarly. Patients discharged to more restrictive environments improved significantly on the BPRS only.

Abstract
OBJECTIVE To examine the demographic characteristics and treatment outcomes of nursing home residents admitted to a geropsychiatric inpatient unit. DESIGN A retrospective cohort design based on an ongoing data base effort. SETTING The geropsychiatric inpatient unit of the Houston Veterans Affairs Medical Center Hospital. PARTICIPANTS All admissions to the unit from nursing homes during an 18-month period. MEASUREMENTS Mini-Mental State Examination, Brief Psychiatric Rating Scale, Hamilton Rating Scale for Depression, Cohen-Mansfield Agitation Inventory, Rating Scale for Side Effects, and Global Assessment of Functioning were administered on admission and discharge. RESULTS Paired t tests comparing change scores revealed significant decreases in general psychiatric symptoms (P < .001), depression (P < .001), and agitation (P < .001); significant improvement in global functioning (P < .001); with no significant changes in cognitive status (P = .485) or side effects (P = .120). When the patients were subgrouped according to reasons for admission, paired t tests revealed decreases in violence (CMAI Factor 1; P = .000), psychosis (BPRS thought disorder scale; P = .000 and hostility subscale; P < .008), and depression (HAM-D; P = .002). Four patients were discharged to less restrictive environments, all with chronic mental illnesses. CONCLUSION Inpatient psychiatric hospitalization significantly benefits nursing home residents with and without dementia who are admitted for severe behavior problems.

Abstract
Several studies have reported an association between aggression and cholesterol levels. The purpose of this study was to investigate the relationship of serum cholesterol and triglyceride levels with aggression and cognitive function in elderly inpatients. One hundred ten patients consecutively admitted to the Geriatric Psychiatry inpatient unit at Houston's Veterans Affairs Hospital received comprehensive evaluations by a multidisciplinary team. Fasting serum cholesterol and triglyceride levels were obtained within 3 days of admission. In addition, two geriatric psychiatrists administered the Mini-Mental State Examination (MMSE) and the Cohen-Mansfield Agitation Inventory (CMAI). Correlation coefficients were calculated between lipid levels, CMAI total and subscale scores, and MMSE scores. Multiple linear-regression analyses were done to further investigate the relation between lipid concentrations and various confounders. We found no significant correlation between serum triglyceride levels and MMSE, CMAI total, and CMAI factor scores. In addition, we found a significant positive correlation between serum cholesterol levels and physical nonaggressive behavior, and a significant negative correlation between serum cholesterol levels and MMSE scores. We found no relationship between aggressive behavior and serum cholesterol or triglyceride levels. However, an association between high cholesterol levels and agitation exists, which may be mediated by the association between high cholesterol levels and impaired cognition.

Abstract
BACKGROUND The efficacy and tolerability of fluoxetine were examined in 31 patients admitted to a geropsychiatric inpatient unit who were initiated and maintained on a regimen of fluoxetine. METHOD The Hamilton Rating Scale for Depression, the Brief Psychiatric Rating Scale, the Mini-Mental State Examination, and the Rating Scale for Side Effects were administered at admission and discharge, and scores were compared using paired t tests. Two patients were withdrawn from fluoxetine prior to discharge because of side effects; their data are not included in the analysis. RESULTS We found significant improvement both in depressive symptoms and in general psychiatric symptoms and nonsignificant improvement in cognitive function. Fluoxetine was well-tolerated, and a significant decrease in the total scores of the Rating Scale for Side Effects was found. Subgroups of older patients (mean age = 75 years), less depressed patients, and demented patients were also examined. In all three groups, we found a statistically significant improvement in depressive symptoms, general psychiatric symptoms, and total side effects. CONCLUSION Fluoxetine appears to be an effective and well-tolerated antidepressant in elderly inpatients of varying age, levels of depression, and psychiatric diagnoses.

Abstract
This study addresses the tolerability of divalproex sodium in elderly psychiatric inpatients with various Axis I diagnoses, using structured assessments. A chart review for a 7-month period on a geropsychiatry inpatient unit identified 13 patients who had been treated with divalproex sodium. All 13 patients received standardized ratings on the Cohen-Mansfield Agitation Inventory (CMAI), Brief Psychiatric Rating Scale (BPRS), Rating Scale for Side Effects (RSSE), and Mini-Mental State Examination (MMSE) on admission and discharge, which were compared using paired t-tests for 12 of the 13 patients. The thirteenth patient was withdrawn from valproate prior to discharge after developing a delirium thought to be secondary to a divalproex-phenytoin interaction. All of the remaining 12 patients tolerated divalproex sodium well with no significant change in MMSE scores (P = .486), CMAI scores (P = .0546), or RSSE scores (P = .124). The change in BPRS score was found to be significant (P = .004). Based on the present study and previously reported case series, divalproex sodium appears to be well tolerated in an elderly psychiatric population.

Abstract
Five elderly, treatment-resistant, depressed, female patients were closely monitored in a research setting during treatment with clomipramine. Plasma clomipramine levels were determined to establish a steady state. Elderly patients (67 to 80 years old) reached a therapeutic steady state at doses lower than that reported for midlife patients. Overall, clomipramine was well tolerated in this group. Depression, measured by the Hamilton Rating Scale for Depression, decreased 42%, and the frequency of somatic complaints, measured by the Rating Scale for Side Effects, declined by 57%. Clomipramine is specifically indicated for the treatment of obsessive-compulsive disorder and may be an alternative for elderly depressed patients, provided that lower doses and plasma clomipramine monitoring are used.

Abstract
Among 547 elderly inpatients grouped by DSM-III-R axis I diagnoses, the diagnostic rate of comorbid personality disorder varied four-fold, from 6% in patients with an organic mental disorder to 24% in those with major depression. The previously reported low prevalence of comorbid personality disorder in geriatric patients may be due to its lower rate of diagnosis among patients with organic mental disorders.

Abstract
Dementia is a complex syndrome associated with cognitive impairment, personality change, and behavioral disturbance. Behavioral symptoms frequently present the greatest challenge for caregivers and are often the determining factor in institutional placement. Determining the need for pharmacologic treatment of an agitated patient requires considering the full range of biopsychosocial variables and ultimately involves assessing the risks and benefits of the medications selected for the patient. In this article, the phenomenology of agitation is reviewed along with the pharmacologic treatment of agitation in patients with dementia, including the use of benzodiazepines, neuroleptics, beta-adrenergic-blocking agents, serotonergic agents, carbamazepine, and lithium.

Abstract
Although grand rounds is an important educational conference in most medical schools and psychiatry departments, there have been few studies of which variables influence faculty and trainee attendance. The authors hypothesized that psychiatry grand rounds attendance would be affected by content area, the speaker's discipline and geographic origin, and the label of "research" in the presentation title. In 3 years of grand rounds presentations at the Baylor College of Medicine Department of Psychiatry and Behavioral Sciences, fewer residents attended grand rounds when "research" was in the label and attendance was greater when the rounds were cosponsored by another agency, presented in honor of someone, or given by an out-of-town speaker.
