This study examines the relation between 3-year-old children's (N = 280) symptoms of inattention, hyperactivity, and aggression and their cognitive, motor, and preacademic skills. When the authors controlled for other types of attention and behavior problems, maternal ratings of hyperactivity and teacher ratings of inattention were uniquely and moderately associated with children's lower cognitive and preacademic skills. The few modest, simple associations between maternal ratings of aggression and children's skills were no longer significant when hyperactivity and inattention were controlled. This suggests that cognitive and preacademic problems among children with attention-deficit/hyperactivity disorder symptoms may begin to emerge as early as age 3. The results highlight the importance of examining the association between different types of behavior problems and young children's skills.

OBJECTIVE: The objective of the study was to determine the effects of short-term levodopa administration on motor, cognitive, and psychiatric aspects of Parkinson's disease (PD). BACKGROUND: The effects of levodopa on mental processes in PD are controversial. Opinions range from the claim that levodopa improves cognition to the opposite view that levodopa causes or exacerbates dementia, delusions, and hallucinations. Of the 800 idiopathic PD patients enrolled in the original DATATOP study, 387 reached the end point of functional disabilities sufficiently severe to require levodopa treatment. There were 263 men and 124 women who were comparable with regard to age, symptom duration of PD, and measures of PD severity. We compared test scores on motor performance, cognitive function, and psychiatric status before levodopa and again within 6 months after initiation of levodopa therapy. RESULTS: Levodopa administration improved all motor functions significantly. The improvement was significantly greater in women than in men. Levodopa administration did not worsen scores on any cognitive tests, and there were quantitatively small but significant improvements in tests of frontal lobe function. Levodopa exerted only minor effects on psychiatric measures. There were small but significant decreases in scores for depression, and increases in vivid dreams and hallucinations. CONCLUSIONS: Levodopa administration for up to 6 months in dosages sufficient to improve motor function has only small effects on cognitive function and psychiatric status in mild to moderate PD patients. We conclude that motor symptoms in early PD, which result from dopamine depletion, are dissociable from cognitive functions and psychiatric status, which may be more dependent on nondopaminergic mechanisms. 相似文献

Mini Mental State Examination (MMSE), Brief Psychiatric Rating Scale (BPRS) and subscales of the BPRS were performed on 73 elderly inpatients (mean age: 67.9 years; standard deviation: 7.2; range: 60-89) diagnosed with DSM-III-R chronic schizophrenia. Forty of the subjects were men and 33 were women. A significant negative correlation was observed between MMSE and the age, factor negative, factor depressive, and total score of BPRS. We believe, however, that it is relatively sufficient to screen for demented illness of schizophrenics using MMSE when considering the age and the psychiatric symptoms (especially negative or depressive symptoms ). Forty-eight (66%) of the 73 patients were categorized as 'demented' by MMSE. These results suggest that the aged inpatients with schizophrenia in a hospital showed certain kinds of cognitive deficits (including senile dementia) more frequently than the general population. 相似文献

OBJECTIVE: To observe the frequency of various psychiatric disorders (depressive disorders, anxiety state and paraphrenic-paranoid disorders). PATIENTS AND METHODS: This study includes the 'cases' of dementia detected in an epidemiological field study done door-to-door, double phased and including non-institutionalized persons aged over 69 years in a rural area. All diagnoses were done by CAMDEX and on these criteria. RESULTS: Depressive disorder was diagnosed in 26.5% studied, paraphrenic or paranoid disorder in 14% and anxiety state in 6.5%. Depression and paraphrenic-paranoid disorder were not associated with the severity of the dementia, whilst anxiety state was more commonly seen in mild dementia. Paraphrenic-paranoid disorders were commoner in women than in men. CONCLUSION: The considerable prevalence of other psychiatric diagnoses in persons with dementia shows that non-cognitive symptoms are common in these patients. 相似文献

OBJECTIVE: The psychopathology associated with early-onset dementia of the Alzheimer type was investigated by comparing the prevalence of psychiatric symptoms in younger subjects (mean age = 59 years) who had very mild or mild dementia with that in older adults (mean age = 72) whose dementia was of equivalent severity. METHOD: Nondemented comparison subjects and persons with very mild or mild dementia of the Alzheimer type were recruited to participate in longitudinal studies. All subjects met strict inclusion and exclusion criteria. Information pertaining to personality changes, affective symptoms, and psychotic symptoms was included in the 90-minute semistructured, physician-administered interview, which was used to assign a clinical dementia rating according to published guidelines. The younger group were age 64 or younger and consisted of 20 nondemented subjects, 11 subjects with very mild dementia, and 18 subjects with mild dementia. The older group, described previously, were 64-83 years old and consisted of 83 nondemented subjects, 41 persons with very mild dementia, and 68 subjects with mild dementia. RESULTS: The psychopathology in the younger subjects was similar to that in the older group. Personality changes occurred in over 80% of the younger persons with very mild illness. Psychotic symptoms were present in over 40% of the younger persons with mild illness but were rare in the group with very mild dementia. CONCLUSIONS: Similar patterns of psychopathology in younger and more elderly persons with dementia of the Alzheimer type support the suggestion that these changes are direct effects of the illness on the CNS. Increased attention to documenting these noncognitive symptoms and studying various treatments is urgently needed. 相似文献

BACKGROUND: It has been suggested that the expression of psychosis may reflect an active morbid process that is associated with increasingly poor outcome unless ameliorated by antipsychotic drugs. METHODS: The subjects of this study were 48 in-patients with schizophrenia, many of whom had been admitted before the introduction of antipsychotic drugs to rural Irish psychiatric hospitals in the late 1950s. Each patient was assessed for positive and negative symptoms, and for general and executive (frontal) cognitive function. RESULTS: After controlling for age and for duration and continuity of subsequent antipsychotic treatment, current severity both of negative symptoms and of general cognitive impairment was predicted strongly by increasing duration of initially untreated psychosis; duration of illness following initiation of antipsychotic medication failed to predict the severity thereof. Neither of these indices of illness duration predicted the severity of positive symptoms or of executive dyscontrol. CONCLUSIONS: Increasing duration of initially untreated psychosis was associated specifically with heightened accrual of prominent negative symptoms and general cognitive impairment. Executive dyscontrol, though also prominent in these patients, may be 'locked-in' at an earlier phase of the illness. 相似文献

Seven patients with hemolytic-uremic syndrome who had major neurological symptoms during the acute illness were neurologically and cognitively evaluated prospectively several years after recovery from the illness. Four patients showed evidence of subtle neurological sequelae, including posturing, clumsiness, poor fine-motor coordination, hyperactivity, and distractibility. Psychoeducational evaluation of all seven subjects revealed mean scores within the average range in cognitive abilities, academic achievement, single word receptive vocabulary, visual/motor planning, overall adaptive functioning, and hyperactivity. The lapse of time (minimum of 7 years) between the acute illness and the psychometric evaluation could have been responsible for our normal results. 相似文献

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. 相似文献

OBJECTIVE: The goal of this study was to define the recurrence or continuation of neuropsychiatric symptoms in patients with Alzheimer's disease who were observed serially for a 1-year period. METHOD: One hundred eighty-one patients with probable Alzheimer's disease were assessed five times at 3-month intervals with a standardized neuropsychiatric rating instrument. RESULTS: Recurrence rates of neuropsychiatric symptoms during the 1-year period were 85% for depression, 93% for agitation, and 95% for psychosis. Symptom frequency at any point in time underestimated the cumulative 1-year frequency. Recurrence rates were significantly greater among patients who had multiple symptoms. Women exhibited more symptoms than men. Patients in the oldest age group (76-87 years) had more psychosis, less depression and agitation, and slower cognitive decline. Psychosis was associated with more rapid cognitive decline, and agitation was associated with more rapid functional deterioration. CONCLUSIONS: These results indicate that once psychiatric symptoms are present in patients with Alzheimer's disease, they frequently recur. These symptoms vary with age, sex, and rate of illness progression. 相似文献

This report studied behavioural disturbances in psychiatric inpatients with dementia of the Alzheimer's type (DAT) in Taiwan. The sample consisted of 75 inpatients with DAT who were consecutively admitted to the geropsychiatric ward. Their behavioural disturbances were obtained from semistructured interviews with families and ward observation. There were eight main behavioural disturbances: getting lost, repetitive phenomena, sleep disturbance, aggression, wandering, hyperphagia, hoarding behaviour, and inappropriate sexual behaviour. Number of behavioural disturbances, wandering, hyperphagia and sleep disturbance were significantly associated with the severity of cognitive impairment. 相似文献

OBJECTIVE: Hereditary spastic paraplegia (HSP) with dementia is a very rare condition. The aim of the paper is to present the first report of HSP in a Fijian Indian family. METHOD: A psychiatrist and a general physician examined the affected members of the family on five occasions over three years. RESULTS: There are three affected individuals in a sibship of seven. The parents are without symptoms and the marriage is non-consanguineous. The course of the disease has been remarkably similar. All subjects were healthy and performing well in the early years of school. In two, symptoms of cognitive loss preceded difficulty with ambulation and in the third, these symptoms appeared concurrently. All subjects had both symptoms by 13 years of age; they were unable to ambulate independently by the mid to late teens, at which time there was dysarthria spastic paraplegia and dementia. One subject suffered a three month episode of hypomanic behaviour. Over the three-year study period deterioration was slight but noticeable. CONCLUSIONS: It is possible that HSP is more commonly associated with pre-senile dementia than is currently recognised. HSP with dementia is a very rare cause of failing school performance. Physical examination of the patient and other family members is indicated if this diagnosis is being considered. 相似文献

BACKGROUND: In the 19th century, deaths from acute exposure to hydrogen sulfide (H2S) portended permanent brain injury from nonlethal doses. The neurobehavioral effects of H2S exposures lasting from moments to years were compared in 16 subjects, 2 years to 22 years afterward. METHODS: Neurophysiologic and psychologic tests were used to appraise mood status and frequencies of 35 symptoms. Functions and frequencies, described as percent predicted adjusted for age, sex, educational achievement, and other factors, were compared with those in an unexposed population. RESULTS: Frequencies were elevated for 31 of 33 symptoms. Balance was impaired (246% predicted with eyes closed, 159% predicted with eyes open), and simple and choice reaction times were prolonged (151% and 130% predicted, respectively). Visual fields performance was decreased to 72% predicted (right) and 55% predicted (left), color discrimination was abnormal, and hearing was decreased. Psychologic domains showed cognitive disability, reduced perceptual motor speed, impaired verbal recall and remote memory, and abnormal mood status. CONCLUSIONS: Exposure to H2S must be avoided. 相似文献

OBJECTIVE: To investigate the specificity of atrophic changes in the corpus callosum (CC) compared with the cerebellum and pons in patients with Alzheimer Disease (AD), healthy elderly subjects (HE), and a sample of prospectively studied subjects who have developed cognitive decline or "incipient dementia" (ID). DESIGN: Cross-sectional comparison by age using quantitative MRI. SETTING: Ambulatory research unit. PARTICIPANTS: Sixty HE subjects (mean age 78.2 years; range 66-95), 20 ID subjects (mean age 88.1 years; range 78-98) and 39 AD subjects (mean age 72.2 years; range 52-91) were enrolled in longitudinal studies of healthy aging or AD. The population was selected for optimal health; all were examined to exclude medical, neurological and psychiatric illness. MEASUREMENTS: Brain atrophy by quantitative MRI. RESULTS: AD subjects had smaller CC than HE or ID subjects, who did not differ from each other. All three sectors of the CC were smaller in AD than in HE or ID subjects. The cross sectional area of the cerebellum and pons did not differ between groups. HE and ID subjects showed a significant decline in CC size with age. No age-related decline was found for AD subjects. The regional atrophy of the CC in AD subjects was significantly related to cognitive function but not to disease duration. CONCLUSIONS: Atrophy of the CC differentiates HE and ID from AD subjects and tracks the cognitive decline of this disease. In addition, optimally healthy subjects show an age-related decline in callosum size. The atrophy is specific to the CC, a cortical projection system, and does not occur in cerebellum or pons. 相似文献

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. 相似文献

OBJECTIVE: To examine risk factors for chronic airway disease (CAD) in elderly nonsmokers, as determined by pulmonary function tests (PFTs), and to correlate reported respiratory symptoms with PFT measures. DESIGN: An observational survey. SETTING: Several communities in California. MEASUREMENTS: Exposures and respiratory history were assessed by standardized questionnaire. PFTs were performed and prediction equations derived. RESULTS: Significant risk factors for obstruction on PFTs in multiple logistic regression included reported environmental tobacco smoke (ETS) exposure (relative risk [RR]=1.44), parental CAD or hay fever (RR=1.47), history of childhood respiratory illness (RR=2.15), increasing age, and male sex. The number of years of past smoking was of borderline significance (RR=1.29 for 10 years of smoking; p=0.06). The prevalence of obstruction on PFTs was 24.9% in those with definite symptomatic CAD, compared with 7.5% in those with no symptoms of CAD. The prevalence of obstruction was 36.0% among those with asthma and 70.6% among those with emphysema. Also, symptomatic CAD correlated with reduction in lung function by analysis of covariance. The mean percent predicted FEV1 adjusted for covariates was 90.6% in persons with definite symptoms of CAD, compared with 97.8% in those without it (p < 0.001). CONCLUSIONS: Age, sex, parental history, childhood respiratory illness, and reported ETS exposures were significant risk factors for obstruction on PFTs. Self-reported respiratory symptoms also correlated significantly with PFTs. 相似文献

OBJECTIVE: To investigate the relationship between cognitive and behavioral impairments in Alzheimer's disease (AD) and to examine whether the addition of cerebrovascular disease modifies that relationship. DESIGN: Correlational analysis. SETTING: An outpatient dementia clinic. PATIENTS: An autopsy-confirmed series of 28 patients with AD and 16 patients with mixed Alzheimer and vascular dementia (MIX). MEASUREMENTS: Neuropsychological and behavioral tests during life: Mini-Mental State (MMS), Blessed Dementia Scale (BDS), Haycox Dementia Behavior Scale (HDBS), and two non-cognitive functional scales derived from the BDS and HDBS. RESULTS: In the AD group, MMS scores correlated significantly with scores on the BDS, HDBS, and two non-cognitive functional scales. In the MIX group, however, no significant relationship was observed between MMS scores and scores on any of the behavioral measures. CONCLUSIONS: These observations suggest that in AD, cognitive and behavioral impairments progress simultaneously. However, with the addition of a vascular component to the dementing process, cognitive and behavioral impairments may progress more independently. 相似文献

OBJECTIVE: To determine whether the apolipoprotein E epsilon4 allele (apoE epsilon4) is associated with cognitive decline in individuals with and without dementia, we conducted a 4-year longitudinal study of subjects with a range of cognitive function. SETTING: At baseline, respondents (n=511) were randomly selected according to age and Mini-Mental State Examination score from a community-based study of dementia among noninstitutionalized persons aged 65 to 84 years. Respondents were examined at baseline and followed up in 3 annual visits. At baseline, subjects were classified as having normal cognitive function, minimal dementia, or dementia, according to criteria from the Cambridge Examination for Mental Disorders of the Elderly (CAMDEX) and the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition. Of the 511 respondents at baseline, 405 who were examined at least 2 times are included in this analysis. MAIN OUTCOME MEASURES: Cognitive decline was determined by a slope estimating yearly change in score on the neuropsychological test, the CAMCOG (the cognitive section of the CAMDEX), and its sub-scales of memory and nonmemory functions. RESULTS: Among the subjects who had normal cognitive function at baseline, apoE epsilon4 carriers showed a significantly greater decline (P<.001) in score on the CAMCOG compared with noncarriers. Differences in decline on the memory and nonmemory subtests were also significant (P<.001). Rates of cognitive decline were not related to apoE epsilon4 status in the groups with minimal dementia and dementia. CONCLUSIONS: In our community-based sample, apoE epsilon4 was associated with the rate of cognitive decline prior to the clinically symptomatic phase of dementia. Knowing the apoE epsilon4 status of those already symptomatic for dementia may not improve knowledge about a patient's prognosis. 相似文献

OBJECTIVE: The authors compared clinical findings of Alzheimer's disease and the so-called Lewy body variant of Alzheimer's disease. METHOD: Available data were analyzed on the clinical features of 58 patients with Alzheimer's disease and 24 patients with the Lewy body variant of Alzheimer's disease who underwent postmortem examination. RESULTS: The proportion of men was significantly larger in the Lewy body variant group than in the Alzheimer's disease group (66.7% versus 34.5%), and, concordantly, the Lewy body variant group was slightly taller. The prevalence of hallucinations and delusions was significantly higher in Lewy body variant subjects than the Alzheimer's disease subjects, but there were no significant differences between the two groups in educational attainment, family history of dementia, age at onset, duration of illness, cognitive impairment, overall severity of illness, or neuropsychological findings. Patients with the Lewy body variant of Alzheimer's disease tended to experience more frequent extrapyramidal side effects of neuroleptics than did the patients with Alzheimer's disease, but for patients in the two groups who were not exposed to neuroleptics, there was little difference in frequency of extrapyramidal side effects. CSF concentration of homovanillic acid (HVA) was significantly lower in the Lewy body variant patients, even when correction was made for height. CONCLUSIONS: The Lewy body variant of Alzheimer's disease may be suspected in elderly male dementia patients who otherwise meet criteria for Alzheimer's disease but who manifest significant psychiatric symptoms and neuroleptic-induced extrapy-ramidal side effects and have low levels of CSF HVA. 相似文献

BACKGROUND: The clinical significance of the 14 and 6 positive spikes (PS) electroencephalographic (EEG) phenomenon is not well established. This study was performed to provide further data regarding the clinical correlates of the PS, particularly attention-deficit/hyperactivity and somatic symptoms. METHODS: Diagnostic information gathered through structured interviews was compared among four groups of psychiatric inpatients aged 4-17 years who underwent an EEG examination over a 2-year period. Groups consisted of patients with: 1) 14 and 6 PS (n = 25); 2) epileptic discharges (n = 29); 3) slow-wave abnormalities (n = 23); and 4) a normal EEG group age and sex matched to the 14 and 6 PS group (n = 25). RESULTS: Attention-deficit hyperactivity disorder (ADHD) symptoms were significantly more frequent in the PS group (chi 2 = 2.96, p < .05) compared to the other three groups combined. Although somatic symptoms were not increased in the 14 and 6 PS group, anxiety symptoms tended to occur more in this group (chi 2 = 3.50, p < .06). CONCLUSIONS: The PS profile appears associated with ADHD symptoms. Possible treatment implications of this finding (e.g., use of anticonvulsants in ADHD patients with PS) need to be explored. 相似文献

This longitudinal study investigated whether age is associated with increases in interindividual variability across 4 ability domains using a sample of 426 elderly community dwellers followed over 3.5 years. InterindividuaI variability in change scores increased with age for memory, spatial functioning, and speed but not for crystallized intelligence for the full sample and in a subsample that excluded dementia or probable dementia cases. Hierarchical regression analyses indicated that being female, having weaker muscle strength, and having greater symptoms of illness and greater depression were associated with overall greater variability in cognitive scores. Having a higher level of education was associated with reduced variability. These findings are consistent with the view that there is a greater range of responses at older ages, that certain domains of intelligence are less susceptible to variation than others and that variables other than age affect cognitive performance in later life.
