Psychiatric symptoms in patients with dementia treated in a psychogeriatric day hospital

Sixty-five consecutive patients with dementia, treated at a psychogeriatric day hospital, were studied regarding prevalence of psychiatric symptoms. The clinical diagnoses were dementia of the Alzheimer type (n = 19), vascular dementia (n = 27), mixed Alzheimer's disease and vascular dementia (n = 13), vascular dementia of frontal type (n = 2), and other diseases (n = 4). Mean age at referral was 75.6 +/- 6.6 years and the average treatment time was 21 +/- 14 months. About 90% of the patients showed one or several significant psychiatric symptoms during the course of dementia. Most common were delirious episodes, anxiety, sleep disturbances, and depressed mood. The relationship between clinical features and the type and duration of dementia was analyzed. Sleep disturbances and depressed mood often appeared early, whereas misidentification and delusions became more prevalent later in the course of dementia. The results indicate that the psychogeriatric day hospital may offer effective and flexible care and support to demented persons living at home.     

Oesophageal reflex responses: abnormalities of the enteric nervous system in patients with oesophageal symptoms

An intraluminal balloon was used to study the peristaltic reflex, which is mediated by the intrinsic nerves of the oesophagus. Serial balloon distension was performed in nine asymptomatic volunteers and 133 patients with oesophageal symptoms. Eight of the volunteers had a normal response with proximal stimulation and distal inhibition of motility. Only 42 patients (31.6 per cent) had a normal response. The commonest abnormal response (39.1 per cent) was some form of failure of the distal inhibitory reflex. Other patterns of abnormality were an unresponsive oesophagus (15.8 per cent) with no motility change during balloon inflation, or spasm (13.5 per cent) proximal to the balloon. These alterations of secondary peristaltic activity suggest that there are abnormalities of the intrinsic (enteric) nerves of the oesophagus. Different abnormalities were found in patients with similar symptoms. Awareness of this difference might allow a more rational approach to treatment. This hypothesis was tested in a small pilot study treating functional dysphagia with cisapride. Three of nine patients had marked symptomatic improvement within 4 weeks and all three had an unresponsive oesophagus. The remaining six patients, who had failure of distal inhibition or a normal response, did not improve.     

Psychiatric manifestations in dementia: phenomenologic perspectives

The study of psychiatric manifestations in dementia has long been overshadowed by the more classical manifestations of the disease, such as memory loss and other cognitive deficits. In recent years, however, psychiatric symptoms as part of the demential process have attracted interest and research has become more specific. Clinicians are faced with diagnostic, treatment and management difficulties related to affective or psychotic symptoms, which account for much distress and morbidity. Several studies indicate that the prevalence of psychiatric manifestations in clinical populations of patients suffering from dementia is high: 15% to 30% for hallucinations, 15% to 30% for delusions, ten percent to 20% for major depression and 40% to 50% for depressed mood. These figures tend to confirm the hypothesis that psychiatric features in dementia are neither infrequent nor atypical. Thus, researchers have sought to link psychotic or depressive symptomatology with several clinical characteristics of dementia, namely stage, severity, prognosis or cognitive dysfunction. Some recent studies involving extensive neuropsychological evaluations indicate that subgroups of patients can be defined according to psychiatric criteria, as well as cognitive or neurological criteria. Unfortunately, results are inconsistent. Some of the contradictions in the literature are related to poorly defined terms and symptoms, a lack of reliable operational criteria, absence of validation of instruments and scales and heterogeneity of the populations studied. Ambiguous syndromes, such as pseudodementia, while illustrative of certain clinical situations, have not been helpful in categorizing demented patients. The author suggests that research focused on specific and clearly defined psychiatric symptoms in dementia will better serve our comprehension of mixed syndromes.     

Association of plasma homovanillic acid with behavioral symptoms in patients diagnosed with dementia: a preliminary report

Neuroleptic treatment of psychotic symptoms or agitated behavior in elderly patients diagnosed with dementia is associated with reduced efficacy and increased rates of neuroleptic-induced parkinsonism in comparison to younger patients with schizophrenia. We report the first study to examine the relationship between an in vivo measure of dopaminergic function, plasma homovanillic acid (pHVA), and ratings of psychosis, agitation, and parkinsonism before and after neuroleptic treatment in dementia patients. Pretreatment pHVA was significantly correlated with parkinsonian rigidity, with a trend observed with agitation and hostility. Though mean pHVA did not change during perphenazine treatment, intraindividual change in pHVA at day 15 was correlated with improvement in hostility, with a similar trend for improvement in agitation. These preliminary findings are consistent with reports associating dopaminergic function with agitated, but not psychotic, symptoms in patients diagnosed with dementia, and with a reduced responsivity of dopaminergic systems to neuroleptic treatment in these patients.     

Psychiatric profile of patients with neurodermatitis

Fifty patients of neurodermatitis attending the dermatology clinic of a general hospital were screened for psychiatric morbidity. Fifty patients suffering from tinea from the same clinic were taken as a control group (age, sex and socio-economic class matched). A majority of neurodermatitis patients were between 21-30 years of age-group (52%), males (84%), married (90%), literate up to primary (42%) and belonged to socio-economic class V (44%). The common sites of neurodermatitis were legs (28%), arms (16%), scrotum (12%) or multiple sites (36%). The duration of symptoms ranged from 1 month to 2 years (average duration was 6 months). The study group also showed significantly higher occupational and psychosexual problems (p < 0.001). The neurodermatitis patients scored significantly higher on N-2 scale and Hamilton rating scale for depression.     

Eudaimonic growth: Narrative growth goals predict increases in ego development and subjective well-being 3 years later.

We examine (a) the normative course of eudaimonic well-being in emerging adulthood and (b) whether people's narratives of major life goals might prospectively predict eudaimonic growth 3 years later. We define eudaimonic growth as longitudinal increases in eudaimonic well-being, which we define as the combination of psychosocial maturity and subjective well-being (SWB). College freshmen and seniors took measures of ego development (ED; to assess maturity; Loevinger, 1976) and SWB at Time 1 (T1) and again 3 years later (Time 2). ED levels increased longitudinally across that time for men and T1 freshmen, but SWB levels did not change. Participants also wrote narratives of 2 major life goals at T1 that were coded for an explicit emphasis on specific kinds of personal growth. Participants' intellectual-growth goals (especially agentic ones) predicted increases in ED 3 years later, whereas participants' socioemotional-growth goals (especially communal ones) predicted increases in SWB 3 years later. These findings were independent of the effects of Big Five personality traits—notably conscientiousness, which on its own predicted increases in SWB. We discuss (a) emerging adulthood as the last stop for normative eudaimonic growth in modern society and (b) empirical and theoretical issues surrounding the relations among narrative identity, life planning, dispositional traits, eudaimonia, and 2 paths of personal growth.

CSF abnormalities in patients with aceruloplasminemia

Aceruloplasminemia is a disorder of iron metabolism characterized by degeneration of the retina and basal ganglia. CSF from affected patients showed a threefold increased iron concentration that was associated with increased superoxide dismutase activity and lipid peroxidation products. These findings support the hypothesis that iron-mediated lipid peroxidation contributes to neurodegeneration in patients with aceruloplasminemia. Such measurements may have value in assessing disease progression as well as the results of iron chelation and other therapeutic interventions.     

Self-control predicts later symptoms of posttraumatic stress disorder.

Self-control, often defined as the ability to control one's thoughts and actions, is one of the most important constructs in psychology. However, the relationship of self-control to clinical disorders has rarely been directly examined. The current study sought to explore this relationship by examining whether self-control predicted posttraumatic stress disorder (PTSD) symptoms in a longitudinal study of 65 inner-city women. Results showed that baseline levels of self-control predicted PTSD symptoms at 3-month follow-up above and beyond other variables in the model. This research combines clinical and social psychological research to reveal the potential role of self-control in protecting against future symptoms of PTSD.

Visuospatial deficits predict rate of cognitive decline in autopsy-verified dementia with Lewy bodies.

Dementia with Lewy bodies (DLB) is often characterized by pronounced impairment in visuospatial skills, attention, and executive functions. However, the strength of the phenotypic expression of DLB varies and may be weaker in patients with extensive concomitant Alzheimer's disease (AD). To determine whether strength of the DLB clinical phenotype impacts cognitive decline, visuospatial and language tests were retrospectively used to predict 2-year rate of global cognitive decline in 22 autopsy-confirmed DLB patients (21 with concomitant AD) and 44 autopsy-confirmed "pure" AD patients. Generalized estimating equations (GEE) revealed a significant interaction such that poor baseline performances on tests of visuospatial skills were strongly associated with a rapid rate of cognitive decline in DLB but not AD (p     

Psychiatric comorbidity in patients with burning mouth syndrome

This paper reports the efficacy results of the randomized, placebo-controlled, field trial of SPf66 malaria vaccine in Costa Marques, Rondonia, Brazil. This region is characterized by the seasonal distribution of Plasmodium falciparum and P. vivax infections, and the recent occupation by migrants from nonendemic areas. A total of 800 individuals of both sexes, ranging in age from seven to 60 years, were included in the study. Of the initial cohort, 572 participants completed the vaccination schedule. Clinical and parasitologic evaluations were obtained by active and passive searches on a periodic basis. The overall protective efficacy against P. falciparum infections was -1.6% (-32.9% to 22.4%), and 14.1% (-17.0% to 36.9%) for the first episode. The overall protective efficacy for P. vivax infections was -19.7% (-44.8% to 1.03%), and -10.8% (-41.1% to 12.8%) for the first episode. No statistical evidence of an overall significant protective effect of SPf66 malaria vaccine against P. falciparum and P. vivax malaria was obtained in this trial.     

Weight loss in patients with Alzheimer-type dementia

Epidemiologic studies show that weight loss is commonly associated with Alzheimer's disease. It would be a manifestation of the disease itself. It is not easy to explain weight loss as subjects with Alzheimer's disease have adequete caloric intakes. Several hypothesis are considered: increased energy expenditure, biologic disturbances, dysfunction in body weight regulation, mesial cortex temporal atrophy. However, at the present time, no study can give a proper explanation. The amelioration of nutritional problems, which lead to many complications (infections, bedsores, bedridden subjects, etc), could be one of the best strategies to lessen the burden of the disease.     

Psychiatric illness in patients with end-stage renal disease

The cause of hyperglycemia in extremely-low-birth-weight (ELBW) infants is not well understood. We studied infants weighing <1,000 g to investigate the relationship of hyperglycemia to blood levels of insulin-like growth factor (IGF)-I and IGF-II. We also compared two methods of treatment for hyperglycemia: continuous insulin infusion and reduction of glucose intake. Fifty-six ELBW infants were enrolled on day 2 of life. Intravenous glucose intake was increased incrementally to a maximum of 12 mg/kg/min on day 6. Infants who developed hyperglycemia were randomly assigned to receive reduced glucose intake (n = 11) or insulin infusion (n = 12). Infants whose blood sugar remained normal served as controls (n = 33). Blood was drawn on days 3, 8 and 15 in all infants, and again when they developed hyperglycemia. Nutritional intake and laboratory results for the treatment groups were compared with controls. Hyperglycemic infants had lower birth weights than controls. Hyperglycemic infants treated with glucose reduction remained <60 kcal/kg/day longer than control or insulin infusion groups (8.6 +/- 1.3 days vs. 4.1 +/- 0.2 and 5.5 +/- 0.6 days). No infants became hypoglycemic during insulin infusion. There was no difference in baseline blood levels of IGF-I or IGF-II among the groups, and these growth factors did not change in response to hyperglycemia. Hyperglycemic infants had baseline levels of insulin which were similar to normal controls, and endogenous insulin increased in response to hyperglycemia in 15 of the 23 infants who developed hyperglycemia. IGF-I and IGF-II are not related to hyperglycemia. In our population, hyperglycemic infants did not have baseline insulin deficiency and most had a normal insulin response to hyperglycemia. Insulin infusion appears safe in these infants and helped to maintain normal caloric intake, whereas glucose reduction was associated with a prolonged caloric deprivation.     

Autonomic dysfunction in patients with dementia of the Alzheimer type

Abnormalities of the noradrenergic system have been documented in the central nervous system of patients with dementia of the Alzheimer's type (DAT). To evaluate the autonomic sympathetic system in DAT, we measured lying and standing blood pressure (BP), pulse, and plasma epinephrine (E) and norepinephrine (NE) in 60 DAT patients (mean age +/- SD = 65 +/- 8 years), and 20 normal elderly controls. DAT patients had normal baseline findings (BP, pulse, NE, and E). Upon standing, plasma NE and E significantly increased in both DAT patients and controls, without group differences. However, the systolic BP response to standing was reduced in DAT patients compared with the normal controls (repeated measures ANOVA, p < 0.01). This impaired response of the systolic BP on standing was particularly evident in DAT patients with symptoms of depression. Severely impaired DAT patients did not differ in E, NE, BP, pulse, or in orthostatic changes from mild-to-moderately impaired patients. These results suggest that the sympathetic response to the stress of standing is functionally impaired in DAT. This deficit was especially evident when DAT was accompanied by depression, consistent with prior studies in non-demented depressed patients.     

Psychiatric hospitalization of senile and arteriosclerotic dementia patients by commitment order under the 1991 Israeli Mental Health Act

Data regarding commitment orders issued by district psychiatrists for elderly patients aged 65 years or older were obtained from the national psychiatric case register. Out of a total of 2,284 commitment orders issued in Israel in the period 1 January 1992 to 30 June 1993 under the 1991 Mental Health Act, 191 (8.3%) involved patients aged 65 and over; these orders were issued for the commitment of 169 patients who suffered from the following ICD-9-CM diagnoses on discharge: senile and arteriosclerotic dementia; transient organic psychotic conditions; schizophrenic disorders; affective psychoses; paranoid states; or other psychiatric disorders. Demographic and clinical characteristics of the senile and arteriosclerotic dementia patients were compared with the same variables in the other diagnostic categories. Results showed that (a) involuntary commitment of senile and arteriosclerotic dementia patients involved a small minority of dementia sufferers; (b) it was usually the patients' first psychiatric admission; (c) most of the patients were discharged within a one-month period; and (d) most of the patients were referred for continuation of treatment in non-psychiatric institutions. Findings (c) and (d) characterized other diagnostic categories as well. The relevance of these findings to the Mental Health Act is discussed.     

Can sonography predict the outcome in patients with achillodynia?

PURPOSE: We evaluated whether the grade assigned to the Achilles tendon's appearance on sonograms can be used to predict the outcome of achillodynia. METHODS: A retrospective evaluation was done of a case series of patients with Achilles tendon pain seen at a sports medicine clinic. The study consisted of chart reviews, telephone follow-up interviews, and grading of ultrasound images of the tendon obtained during the initial visit. The grading scheme was as follows: grade 1, normal tendon; grade 2, enlarged tendon; and grade 3, tendon containing a hypoechoic area, regardless of size. The time needed to recover from symptoms was compared between grades using survival analysis. RESULTS: The group consisted of 33 patients, with a mean age of 35.8 years and a mean follow-up time of 24.3 months. There was a statistically significant difference in the time to full recovery between grades (p = 0.02). Patients with grade 1 tendons had a prompter resolution of symptoms than did patients with grade 2 or 3 tendons. CONCLUSIONS: This retrospective study of the outcome of achillodynia demonstrates the possible use of tendon sonography as a prognostic tool to supplement physical examination.     

Systemic changes of the immune system in patients with Alzheimer's dementia

OBJECTIVE: The etiology of Alzheimer's disease (AD) is still unknown. Recent investigations have shown that immune and inflammatory mechanisms could be of importance in the pathophysiology of AD. In this study 10 different immune parameters were measured to further investigate immunological changes in AD. PATIENTS AND METHODS: In 30 randomized patients with AD (20 females and ten males aged 74.5 +/- 6.5 years) as well as 13 controls aged 70.7 +/- 8.4 years, mostly relatives of the patients, all free of acute infection, serum concentrations of IgA, IgG, IgM, C3, C4, circulating immune complexes, sCD23, cardiolipin and the soluble cytokine receptors interleukin 2-receptor (sIL2-R) and tumor necrosis factor-receptor (sTNF-R) were measured. Diagnosis of AD was made according to NINCDS/ ADRDA criteria. The degree of dementia was determined by Mini-Mental-State-Examination (MMSE). RESULTS: Compared to the control group, patients with AD had significantly increased IgA (369,3 +/- 160,9 mg/dl vs 253.5 +/- 101.8 mg/dl [P = 0.02]), sCD23 [207.4 +/- 217.7 I. U./ml vs 80.6 +/- 35.5 I. U./ml [P = 0.004]), sIL2-R (829.6 +/- 742.1 I. U./ml vs 299.7 +/- 168.5 I. U./ml [P = 0.001]) and sTNF-R (4.6 +/- 2.0 I. U./ml vs 2.9 +/- 1.1 I. U./ml [P = 0.001]) levels. A negative correlation was seen between MMSE and sTNF-R (r = -0.34; P < 0.05). CONCLUSION: These findings indicate a chronic state of immune activation in AD and support the hypothesis of immune mediated mechanisms as part of the pathogenesis of AD. Prospective studies of the effect of anti-inflammatory drugs on the progression of AD will be needed.     

Psychiatric symptoms and community violence among high-risk patients: A test of the relationship at the weekly level.

Given the availability of violence risk assessment tools, clinicians are now better able to identify high-risk patients. Once these patients have been identified, clinicians must monitor risk state and intervene when necessary to prevent harm. Clinical practice is dominated by the assumption that increases in psychiatric symptoms elevate risk of imminent violence. This intensive study of patients (N = 132) at high risk for community violence is the first to evaluate prospectively the temporal relation between symptoms and violence. Symptoms were assessed with the Brief Symptom Inventory and threat/control override (TCO) scales. Results indicate that a high-risk patient with increased anger in 1 week is significantly more likely to be involved in serious violence in the following week. This was not true of other symptom constellations (anxiety, depression, TCO) or general psychological distress. The authors found no evidence that increases in the latter symptoms during 1 week provide an independent foundation for expecting violence during the following week.
