Abstract
OBJECTIVES It remains unclear if geriatric patients with different delirium motor subtypes express different levels of motor activity. Thus, we used two accelerometer-based devices to simultaneously measure upright activity and wrist activity across delirium motor subtypes in geriatric patients. DESIGN Cross-sectional study. SETTINGS Geriatric ward in a university hospital in Norway. PARTICIPANTS Sixty acutely admitted patients, ≥75 years, with DSM-5-delirium. OUTCOME MEASURES Upright activity measured as upright time (minutes) and sit-to-stand transitions (numbers), total wrist activity (counts) and wrist activity in a sedentary position (WAS, per cent of the sedentary time) during 24 hours ongoing Delirium Motor Subtype Scalesubtyped delirium. RESULTS Mean age was 86.7 years. 15 had hyperactive, 20 hypoactive, 17 mixed and 8 had no-subtype delirium. We found more upright time in the no-subtype group than in the hypoactive group (119.3 vs 37.8 min, p=0.042), but no differences between the hyperactive, the hypoactive and the mixed groups (79.1 vs 37.8 vs 50.1 min, all p>0.28). The no-subtype group had a higher number of transitions than the hypoactive (54.3 vs 17.4, p=0.005) and the mixed groups (54.3 vs 17.5, p=0.013). The hyperactive group had more total wrist activity than the hypoactive group (1.238×104 vs 586×104 counts, p=0.009). The hyperactive and the mixed groups had more WAS than the hypoactive group (20% vs 11%, p=0.032 and 19% vs 11%, p=0.049). CONCLUSIONS Geriatric patients with delirium demonstrated a low level of upright activity, with no differences between the hyperactive, hypoactive and mixed groups, possibly due to poor gait function. The hyperactive and mixed groups had more WAS than the hypoactive group, indicating true differences in motor activity across delirium motor subtypes, also in geriatric patients. Wrist activity appears more suitable than an upright activity for both diagnostic purposes and activity monitoring in geriatric delirium.

Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) affect almost all patients with dementia and are a major focus of study and treatment. Accurate assessment of NPS through valid, sensitive and reliable measures is crucial. Although current NPS measures have many strengths, they also have some limitations (e.g. acquisition of data is limited to informants or caregivers as respondents, limited depth of items specific to moderate dementia). Therefore, we developed a revised version of the NPI, known as the NPI-C. The NPI-C includes expanded domains and items, and a clinician-rating methodology. This study evaluated the reliability and convergent validity of the NPI-C at ten international sites (seven languages). METHODS Face validity for 78 new items was obtained through a Delphi panel. A total of 128 dyads (caregivers/patients) from three severity categories of dementia (mild = 58, moderate = 49, severe = 21) were interviewed separately by two trained raters using two rating methods: the original NPI interview and a clinician-rated method. Rater 1 also administered four additional, established measures: the Apathy Evaluation Scale, the Brief Psychiatric Rating Scale, the Cohen-Mansfield Agitation Index, and the Cornell Scale for Depression in Dementia. Intraclass correlations were used to determine inter-rater reliability. Pearson correlations between the four relevant NPI-C domains and their corresponding outside measures were used for convergent validity. RESULTS Inter-rater reliability was strong for most items. Convergent validity was moderate (apathy and agitation) to strong (hallucinations and delusions; agitation and aberrant vocalization; and depression) for clinician ratings in NPI-C domains. CONCLUSION Overall, the NPI-C shows promise as a versatile tool which can accurately measure NPS and which uses a uniform scale system to facilitate data comparisons across studies.

Abstract
Major depressive disorder (MDD) is phenomenologically heterogeneous, which has prompted investigation of intermediate MDD phenotypes based on specific key symptoms. Presence and type of psychomotor disturbance may be an important psychopathologic feature that differentiates clinically distinct forms of juvenile MDD. This study examined the phenotypic status of three putative MDD phenotypes in a community sample of 941 youths: (1) agitated depression (MDD with psychomotor agitation), (2) retarded depression (MDD with psychomotor retardation), and (3) agitated-retarded depression (MDD with psychomotor agitation and retardation within an episode). Hasler et al.'s [2004: Neuropsychopharmacology 29:1765-1781] criteria of specificity (degree of association with relevant symptoms and conditions related to the disease of interest versus other psychiatric conditions), stability (degree of stability over time), and heritability (degree of familial aggregation with relevant conditions) were used to evaluate the phenotypic significance of these subtypes. Results were suggestive that agitated depression was a relatively specific phenotypic syndrome characterized by irritability, arousal, physical complaints, and vulnerability to anxiety disorders and alcohol dependence; low stability across depressive episodes; and low heritability. Agitated-retarded depression was relatively specific and characterized by increased severity, recurrence, vegetative symptoms, suicidal ideation, social impairment, endogeneity, and vulnerability to anxiety disorders and bulimia; low stability across episodes; and modest heritability. Although retarded depression was associated with some specific distinguishing characteristics, most associations were explained by the increased severity of this phenotype. Retarded depression evidenced little stability or heritability. These findings offer partial support of the phenotypic status of agitated and agitated-retarded depression in youths.

Abstract
BACKGROUND Sedatives and analgesic drugs give comfort and allow adequate respiratory support to critically ill patients in mechanical ventilation (MV). Its improper use may increase the duration of MV. Clinical guidelines suggest implementation of protocols, however this is seldom done in clinical practice. AIM To compare in MV patients, nurse-applied guided by protocol administration of sedatives and analgesic drugs (protocol: group P) with the habitual practice using physicians criteria (control: group C). MATERIAL AND METHODS Inclusion criteria was the need of MV more than 48 h. The exclusion criteria were acute neurological diseases, hepatic cirrhosis, chronic renal failure and limitation of therapeutic efforts. Midazolam and fentanyl were used in both groups. The level of sedation was monitored with the Sedation Agitation Scale (SAS). In the P group, trained nurses applied algorithms to adjust the sedative doses according to a predefined SAS goal. RESULTS Forty patients were included, 22 aged 65+/-19 years in group P and 18 aged 54+/-21 years in group C. Apache II scores were 16+/-8 and 19+/-8 in each group. SAS score was more frequently evaluated within goal boundaries in group P than in group C (44% and 32%, respectively p =0.001). No differences in the proportion of patients with inadequate sedation were observed between treatment groups. Midazolam doses were lower in P than in C group (0.04 (0.02-0.07) and 0.06 (0.03-0.08) mg/kg/h respectively, p =0.005). CONCLUSIONS The implementation of sedation protocol applied by nurses improved the quality of sedation and reduced the doses of Midazolam in mechanically ventilated patients.

Abstract
The goal of the study was to compare the reliability and validity of 3 Sedation Agitation Scale. Two nurses and a physician conducted 130 observations simultaneously. They found an excellent interrater reliability in the Richmond Agitation Sedation Scale (r>0.86), and high correlations between the Richmond Agitation Sedation Scale and the Sedation Agitation Scale and Visual Analog Scale scales (r=0.92, r=0.85). The research findings will help to assert Richmond Agitation Sedation Scale as a daily assessment tool in the intensive care unit, and it will pave the way for construction a sedation protocol according to the Richmond Agitation Sedation Scale level.

Abstract
OBJECTIVE To examine the nature of agitation in patients with brain injury and quantify the relation between agitation and patient progress in rehabilitation. DESIGN Cross-sectional, correlational. SETTING Urban, inpatient rehabilitation facility in the midwestern United States. PARTICIPANTS Sixty-nine patients with acquired brain injury admitted to an acute rehabilitation hospital. MAIN OUTCOME MEASURES Therapy Engagement using the Rehabilitation Therapy Engagement Scale; Functional Status using the Functional Independence Measure. RESULTS Agitated behavior was inversely associated with engagement in rehabilitation therapy even after controlling for injury severity. Engagement in therapy mediated the relation between agitated behavior and progress in rehabilitation as assessed using a Functional Independence Measure efficiency ratio. CONCLUSIONS Progress in acute brain injury rehabilitation appears to be meaningfully influenced by the complex interplay among injury severity, agitation, and engagement. The findings are consistent with a theoretical model, suggesting that agitated patients make less progress in rehabilitation not only because of greater injury severity but also because agitation disrupts engagement in rehabilitation therapies. Multiple clinical purposes may be better served by measuring behavioral excess on a continuum than in a dichotomous fashion.

Revisiting cycloid psychosis: a case of an acute, transient and recurring psychotic disorder. Schizophr Res 2006; 82:261-4.

Abstract
We report a case of recurrent psychosis, spanning decades, with full inter-episode recovery and minimal functional impairment. While it is difficult to classify this disorder using DSM IV-TR criteria, Leonhard and others have described a 'cycloid psychosis' that correlates well with the phenomenology and course of this case. We believe this may represent a subset within the ICD-10 category of 'acute and transient psychotic disorders'. While this disorder, of unknown incidence, is not well reported in the U.S., it is worthy of further investigation and clinical attention given its generally favorable prognosis and potentially distinct pathophysiology and treatment.

Abstract
STUDY AIM To test diagnostic validity or utility of agitated depression (AD) in bipolar II disorder (BP-II). METHODS Three hundred and twenty BP-II major depressive episode (MDE) outpatients interviewed with the Structured Clinical Interview for DSM-IV, Hypomania Interview Guide (HIG), and Family History Screen. AD defined as MDE with psychomotor agitation. Mixed depression defined as MDE with > or =4 hypomanic symptoms. AD, non-AD, mixed-AD, non-mixed-AD, and mixed-non-AD were compared versus diagnostic validators. RESULTS AD was present in 35.0%, 75.8% of AD were mixed, while only 14.3% of non-AD were mixed (P=0.0000). AD (n=112), versus non-AD (n=208), had significantly higher age, more females, recurrences, bipolar I family history, and much more concurrent hypomanic symptoms. Mixed-AD (n=85), versus non-mixed-AD (n=27), was not significantly different, apart from more hypomanic symptoms (by definition), but there were clinically significant differences. CONCLUSIONS Findings may partly support subtyping of AD in BP-II, on the basis of its frequent clustering of hypomanic symptoms, and its different family history. This subtyping may impact on treatment of BP-II depression, as antidepressants alone may increase agitation while mood stabilising agents can treat agitation before using antidepressants.

Abstract
BACKGROUND Early authors described hypomanic symptoms as mixed features in depressive episode, but this syndrome has not been sufficiently explored in previous studies. METHODS 958 consecutive depressed patients were assessed by using a standardized method in terms of 43 psychiatric symptoms at hospitalization. RESULTS A principal component analysis, followed by varimax rotation, extracted six interpretable factors: typical vegetative symptoms, depressive retardation/loss of feeling, hypomanic syndrome, anxiety, psychosis, and depressive mood/hopelessness. The extracted factor structure was relatively stable among several patient groups. There was no evidence that the hypomanic factor was exaggerated by antidepressant pretreatments before hospitalization. Bipolar diagnoses were associated with higher scores on depressive retardation and hypomanic symptoms, and a lower score on anxiety. LIMITATIONS Psychiatric syndromes and their interrelationships, found in the present study, may be strongly influenced by the rating instrument used. The sample of this study was depressed inpatients. The results should not be generalized for depressed outpatients or epidemiological depressed populations. CONCLUSIONS Hypomanic symptoms, as characterized by the flight of ideas, racing thought, increased drive, excessive social contact, irritability, and aggression are a salient syndrome in acutely ill depressed patients, lending support to the factor validity of mixed depression. The symptoms may not be related to pretreatments with antidepressants, or comorbidity of substance abuse, suggesting that they reflect various natural phenomenological manifestations of depressive episodes. Anxiety is unlikely to play a major role in the core phenomenological features of mixed depression. Hypomanic symptoms during a depressive episode were more represented in bipolar disorders, which may serve for further clarifications of latent bipolarity in unipolar depression, and prediction of switch into maniform states under biological depression treatments.

Abstract
PURPOSE The diagnostic validity of agitated depression (AD, a major depressive episode (MDE) with psychomotor agitation) is unclear. It is not classified in DSM-IV and ICD-10 classification of mental and behavioural disorder (ICD-10). Some data support its subtyping. This study aims to test the subtyping of AD. METHODS Consecutive 245 bipolar-II (BP-II) and 189 major depressive disorder (MDD) non-tertiary-care MDE outpatients were interviewed (off psychoactive drugs) with Structured Clinical Interview for DSM-IV Axis I Disorders--Clinician Version (SCID-CV), Hypomania Interview Guide (HIGH-C), and Family History Screen. Intra-MDE hypomanic symptoms were systematically assessed. AD was defined as an MDE with psychomotor agitation. Mixed AD was defined as an MDE with four or more hypomanic symptoms (including agitation). FINDINGS AD was present in 34.7% of patients. AD was mixed in 70.1% of AD patients. AD, vs. non-AD, had significantly (at alpha = 0.05) lower age at onset, more BP-II, females, atypical depressions, bipolar-I (BP-I) and BP-II family history, and was more mixed; racing/crowded thoughts, irritability, more talkativeness, and risky behaviour were significantly more common. Mixed AD, vs. non-AD, had significantly (at alpha = 0.01) lower age at onset, more intra-MDE hypomanic symptoms, BP-II, females, atypical depressions, BP-II family history, and specific hypomanic symptoms (distractibility, racing thoughts, irritable mood, more talkativeness, risky activities). Mixed AD, vs. non-mixed AD, had significantly more intra-MDE hypomanic symptoms (by definition), more recurrences, and more specific hypomanic symptoms (by definition). Non-mixed AD, vs. non-AD, had significantly more intra-MDE hypomanic symptoms and more talkativeness. CONCLUSIONS AD was common in non-tertiary-care depression outpatients, supporting its diagnostic utility. AD and many bipolar diagnostic validators were associated, supporting its link with the bipolar spectrum. Mixed AD, but not non-mixed AD, had differences vs. non-AD similar to those of AD, suggesting that psychomotor agitation by itself may not be enough to identify AD as a subtype. Findings seem to support the subtyping of mixed AD. This subtyping may have important treatment impact, as antidepressants alone might increase agitation.

Abstract
OBJECTIVE To determine sex differences in extent and type of posttraumatic agitation during acute rehabilitation. DESIGN This prospective, observational study was performed at a Midwest, regional, university-based acute rehabilitation center. RESULTS In a total of 158 subjects, comprising 120 men (76%) and 38 women (24%), there were no significant differences between male and female subjects for age, Glasgow Coma Scale score, Rancho Los Amigos Level of Cognitive Functioning Scale, Mini Mental State Exam, days in acute hospital, and days in rehabilitation. No difference in incidence was observed between sexes based on the criterion of agitation as three or more abnormal total Agitated Behavior Scale scores in 48 hrs (P = 0.890). Also, no difference in posttraumatic agitation between the two sexes (P = 0.396) was observed with the criterion of agitation as two or more abnormal total Agitated Behavior Scale scores in 2 days. There were no differences observed between the sexes for peak intensity and average intensity for the total score or each of the factor scores of the Agitated Behavior Scale. CONCLUSION Posttraumatic agitation is seen in approximately 50% of patients after traumatic brain injury and usually lasts for <10 days. There are no significant sex differences in the frequency, duration, presentation, or extent of posttraumatic agitation. These data imply that both sexes, despite any predetermined notions, should be treated equally with respect to posttraumatic agitation management.

Abstract
STUDY OBJECTIVE To evaluate the anesthesia issues involved in caring for mentally handicapped outpatients. DESIGN Retrospective chart review. SETTING University-affiliated outpatient ambulatory center. PATIENTS Twenty adult patients scheduled for gynecological procedures. INTERVENTIONS None. MEASUREMENTS Data collection sheet was used to record patients' age, ASA status, procedure, premedication, intravenous placement, degree of agitation, airway control, induction (method and drugs), intraoperative anesthesia care, postoperative medications, total time in hospital, postanesthesia care unit time and disposition. MAIN RESULTS Agitation was present in 100% of the patients. A significant number of these patients were ASA III, needing oral or intramuscular sedation (35%) or mask induction prior to placement of an intravenous line. Severely agitated patients had the longest stays in the postanesthesia care unit (PACU). CONCLUSIONS Agitation was the main reason why 90% of the patients required intubation for relatively minor procedures. Agitation was the main factor leading to prolonged recovery room time.

Abstract
OBJECTIVE The study aimed to explore how prevalent agitated depression is in bipolar I disorder, whether it represents a mixed state, and whether it differs from nonagitated depression with respect to course and outcome. METHOD From 313 bipolar I patients with an index episode of major depression, the authors selected those fulfilling Research Diagnostic Criteria for agitated depression. These 61 patients were compared to 61 randomly recruited bipolar I patients with an index episode of nonagitated depression and 61 randomly recruited bipolar I patients with an index episode of mania regarding demographic, historical, and clinical features. The two depressive groups were also compared regarding time to recovery from the index episode, treatment received for that episode, percentage of time spent in an affective episode during a prospective observation period, and 5-year outcome. RESULTS Patients with agitated depression were consistently not elated or grandiose, but one-fourth had the cluster of symptoms with racing thoughts, pressured speech, and increased motor activity, and one-fourth had the paranoia-aggression-irritability cluster. Compared to patients with nonagitated depression, they had a longer time to 50% probability of recovery from the index episode, were more likely to receive standard antipsychotic drugs during that episode, and spent more time in an affective episode during the observation period. CONCLUSIONS The occurrence of agitated depression in bipolar I disorder is not rare and has significant prognostic and therapeutic implications. Whether the co-occurrence of a major depressive syndrome with one or two of these symptomatic clusters makes up a "mixed state" remains unclear.

Abstract
STUDY OBJECTIVES To determine the validity and reliability of the Sedation-Agitation scale (SAS) when administered by intensive care unit (ICU) nurses with no experience in its use. DESIGN Prospective, psychometric evaluation. SETTING Adult medical-cardiac ICU. PATIENTS Sixty patients. INTERVENTION Sedation and agitation were observed simultaneously but independently by nurses and two investigators, and patients were rated with the SAS. The assessment of an experienced clinical nurse specialist was recorded on visual analog scales (VAS) for sedation (VAS-S) and agitation (VAS-A). MEASUREMENTS AND MAIN RESULTS The SAS scores of ICU staff nurses were compared with VAS scored by the clinical nurse specialist using Pearson correlation coefficient. The SAS correlated well with VAS-S (Spearman's p = -0.77, p<0.001). Neither SAS nor VAS-A was correlated (Spearman's p = 0.05, p>0.5), but there were few observations of agitated patients. The SAS interrater agreement was excellent between the two trained investigators (weighted K = 0.93, p<0.001) and between investigators and staff nurses (weighted K = 0.85 and 0.87, p<0.001 for both). CONCLUSION The SAS is reliable when administered by staff nurses with no experience with it. Due to the paucity of observations of agitated patients, we were unable to determine its validity for assessing agitation.

Abstract
BACKGROUND Psychomotor agitation is commonly associated with various psychiatric disorders. This article reviews the definition and measurement of agitation over the past 100 years. METHODS Definitions and descriptions of agitation were taken from dictionaries of etymology, medicine and psychiatry, and from psychiatric textbooks. A systematic MEDLINE (1966-1996) search of 'psychomotor', 'agitation', and 'restlessness' was conducted. This was augmented by a search for other relevant references cited in the articles identified by MEDLINE. RESULTS The definition of psychomotor agitation has varied in ambiguous and contradictory ways, both over time and in contemporary writings. Tools developed to measure agitation are either too unreliable, or else reflect this conflict of definition and are not comparable. CONCLUSIONS A preferred definition of agitation is proposed which takes into account both theoretical and empirical data. This has implications for further research into psychomotor agitation in classification of and treatment response in affective disorders, old age psychiatry and the evaluation of putative anti-agitation drugs.

Abstract
OBJECTIVE To describe the level of sedation for a cohort of mechanically ventilated adult intensive care unit (ICU) patients using validated subjective and objective tools. DESIGN Prospective convenience sample. SETTING Multidisciplinary 34-bed ICU at Maine Medical Center, a 599-bed nonuniversity, academic medical center. PATIENTS Sixty-three adult ICU patients were monitored during 64 episodes of ventilatory support. MEASUREMENTS AND MAIN RESULTS Patients were prospectively evaluated by one trained investigator using the revised Sedation-Agitation Scale (SAS) and were simultaneously monitored for 1 to 5 hrs using the Bispectral Index (BIS), a numeric scale from 0 to 100 derived from the electroencephalogram. BIS values were assigned to baseline, stimulated, and average conditions for each patient by a separate investigator blinded to SAS scores. Ventilator settings, medications, and the lung injury severity (LIS) score were also recorded. Sedation levels varied from very deep sedation (SAS score = 1, BIS score = 43) to mild agitation (SAS score = 5, BIS score = 100). Heavily sedated patients (SAS score = 1-2, n = 20) had higher FIO2 (0.52 vs. 0.42, p = .008), oxygenation index (9.4 vs. 5.4, p = .03), and LIS scores (1.3 vs. 0.7, p = .004) and lower baseline (66 vs. 78, p = .01), average (66 vs. 81, p < .001), and stimulated (89 vs. 96, p = .016) BIS scores compared with more awake patients. Patients with intermittent neuromuscular blockade use (n = 4) had higher FIO2 (0.65 vs. 0.44, p = .006), minute ventilation (14.6 vs. 9.9 L/min, p = .005), positive end-expiratory pressure (7.5 vs. 4.8 cm H2O, p = .05), oxygenation index (15.7 vs. 6.0, p < .001), and LIS scores (3.3 vs. 1.0, p = .036) and were more sedated, with higher suppression ratios (3.5 vs. 0.6, p = .05) and lower SAS scores (1.5 vs. 4, p = .035). The average BIS values correlated well with SAS (r2 = .21, p < .001). CONCLUSIONS SAS and BIS work well to describe the depth of sedation for ventilated ICU patients. Deeper sedation and intermittent neuromuscular blockade were used for patients with greater ventilatory requirements and more severe lung disease. The correlation between subjective and objective scales varied in medical, surgical, and trauma patients. Further research with SAS and BIS may facilitate the development of quantitative sedation guidelines for the ICU.

Abstract
Health care providers deal with disruptions from geriatric patients routinely. Despite the negative impact on provider efficiency, provider-patient relations, and patient well-being, there have been no systematic clinical studies of the impact of disruptive behaviors on geriatric inpatient care. This article presents a taxonomy for these behaviors, applying them to a study of disruptive behaviors and concomitant nursing interventions on a geriatric evaluation and management (GEM) unit. The sample, consisting of 23 nursing staff (16 RNs, 4 LPNs, and 3 nurse aides), was followed over 8 weeks (five shifts per week, distributed randomly over day, evening, and night shifts). An experienced pair of RN observers logged all disruptive behaviors and the associated interventions employed by the nursing providers. The taxonomy was validated on 97 disruptive events (113 disruptive behaviors) initiated by 87 patients. The major findings of the study were: (a) disruptive behaviors are common on a GEM unit; (b) behaviors that disrupt care are recognized only 50% of the time by nursing staff; (c) interventions, when used singly, were found successful 45% of the time; (d) multiple simultaneous interventions may be more successful than single interventions but were used in only 16% of cases; and (e) selection of interventions may be associated with staff education level.

Abstract
BACKGROUND Four types of agitation have been identified: physically aggressive behaviors, physically nonaggressive behaviors, verbally aggressive behaviors, and verbally nonaggressive behaviors. These pose a major challenge to caregivers and are sometimes indicators of the emotional state of the older person. Longitudinal changes in these four subtypes of agitated behaviors were examined. METHODS One hundred and four community-dwelling participants of five senior day care centers (mean age = 79) were followed up for 2 years. Their agitation was assessed, as was their cognitive functioning, affect, and medical functioning. RESULTS Although physically nonaggressive, physically aggressive, and verbally aggressive behaviors increased significantly over 2 years, verbally nonaggressive behaviors did not show significant changes over time. These patterns can be partially explained by the relationship between the different types of agitation and cognitive functioning. Increases in physically nonaggressive behaviors from start to end of the 2 years were predicted by greater cognitive impairment at baseline and by receiving a smaller number of medications at baseline. Increases in verbally aggressive behaviors and in physically aggressive behaviors during the study period correlated significantly with a greater decline in cognitive functioning and increased depression at baseline. In addition, increases in physical aggression were correlated with greater cognitive impairment at baseline. CONCLUSIONS The course of change for each type of agitation was unique. The relationships between inappropriate behaviors, cognitive functioning, physical health, and depression over time are complex and vary by type of agitation.

An instrument, that validly and reliably identifies and measures agitation is required to evaluate environmental modifications, interpersonal strategies, psychopharmacological interventions, directed toward managing these commonly occurring and highly-disabling emotions and behavior. The conceptualization of agitation on a continuum from anxiety to aggression provides a practical framework for guiding clinical practice toward the early identification and intervention of agitation. The results of this study established the reliability and validity of the Overt Agitation Severity Scale (OASS) in measuring agitation severity in young adult psychiatric inpatients based on objectifiable vocalizations and motoric upper and lower body behaviors. The OASS differs from other agitation scales in its ability to capture both the intensity and frequency of observable behavioral manifestations of agitation, as opposed to subjective interpretations and a diffuse range of symptoms and problem behaviors.

Abstract
As part of a multicenter project to study noncognitive behavioral disturbances in dementia, the authors developed a comprehensive caregiver-rated questionnaire for these behaviors. The authors determined the reliability of caregiver ratings and compared caregiver ratings with clinician ratings using standard instruments. Caregivers showed good test/retest reliability for ratings of all types of patient behavioral disturbance. Caregiver interrater reliability was highest for depression and lowest for psychosis. The correlation between caregiver reports and professional assessments was highest for agitation, intermediate for psychosis, and lowest for depression. The match between caregiver and clinician assessments of patient behaviors appears to vary significantly by the type of behavior assessed.

Abstract
Treating agitation in elderly people is a complex process. Faced with a paucity of empirical information, clinicians tend to adopt a therapeutic approach based on their clinical evaluation. This article offers a rational approach that will help physicians to better understand, evaluate, and treat agitation.

Abstract
A historically orientated analysis of a disease that must be seen in connection with menstruation is made on the basis of literature on periodical psychoses in adolescence, which are described as nosologically separate disturbances. This relation turns out to be by no means obligatory, and this also applies to the homogeneity of the disease. Psychomotor disturbances of psychopathological importance are described by means of ideally typical cases of disease and presented with a differentiated diagnosis. Psychoses occurring during different periods in childhood and adolescence, do not show any sex-specific differences and no absolute dependence in accordance with the menstruation rhythm, but are mostly connected with a hereditary and also a perinatal strain in childhood. In their acute and long-term progress the psychomotoric disturbances allow a differentiated prognosis and therefore a therapeutic explanation. They can be classified in accordance with the Wernicke-Kleist-Leonhard classification schema as motility psychosis and periodic catatonia. With this in mind, the positive-negative dichotomy of schizophrenic disturbances in childhood and adolescence should be carefully reconsidered.

Abstract
Violence and agitation are two different behaviors however not always differentiated. There are not only physical violence but also moral violence such as erotomania eventually more dangerous. There is no clear definition of violence. Research should be improved. Today there is an increase of different types of violence, such as self-inflicted violence as in suicidal behavior, rather frequently associated with alcoholism. Clinical experience is given from l'Infirmerie Psychiatrique, a forensic psychiatric emergency department.

Abstract
Involuntary movement disorders were investigated in a psychiatric hospital in Japan. The prevalence of tardive dyskinesia was 9.9% and four clinical variants of tardive dyskinesia could be classified. Of the 716 patients, tardive dystonia was identified in 15 cases, tardive akathisia in one, respiratory dyskinesia in two and rabbit syndrome in 17. The existence of tardive forms for acute dystonic reactions and akathisia suggests that any type of acute extrapyramidal symptoms can have a tardive form.

Abstract
In a prospective 4-year follow-up study, 26 out of 31 patients initially diagnosed as cycloid psychoses were investigated (anxiety-happiness psychosis n = 15; confusion psychosis n = 8; motility psychosis n = 3). Patients were independently interviewed by two clinical researchers. 61.5% showed one or several 'first-rank symptoms' according to Schneider. In addition, the SADS-LA was applied for RDC and DSM-IIIR diagnoses. According to these classification systems most of the patients were diagnosed as schizophrenic or schizoaffective. Personal interview as well as application of the Strauss-Carpenter Outcome Scale indicated a highly favorable clinical outcome, i.e. lack of affective or behavioral defective states in literally all patients of the study. These results justify the distinction of the cycloid psychoses as a nosological entity in general and--less convincingly--of the three subtypes of cycloid psychoses.

Abstract
Eighty-two schizophrenic outpatients receiving maintenance antipsychotic medication were assessed for akathisia and tardive dyskinesia. Thirty-nine (48%) manifested patterns of nondyskinetic, restless movement characteristic of akathisia. On the basis of their clinical features, these patients were divided into three groups: "acute" akathisia (recent onset, related to an increase in antipsychotic drug dose); "pseudoakathisia" (motor signs but no subjective symptoms); and "chronic" akathisia (a mixed category including persistent acute akathisia and "tardive" akathisia with the pharmacologic characteristics of tardive dyskinesia). Coarse, jerky foot tremor was observed as an invariable accompaniment of acute akathisia. A significant association was found between choreoathetoid limb dyskinesias, orofacial dyskinesias, and the presence of chronic akathisia. Also, the findings suggested a possible relationship between pseudoakathisia, orofacial and limb dyskinesia, and the severity of negative schizophrenic symptoms.
