The study was conducted from November 1995 to May 1996 at the one general hospital in Seoul. The total subjects of this study were 412 patients who have the experience of fall accident, among them 31 was who have fallen during hospitalization and 381 was who visited emergency room and out patient clinic. The purposes of this study were to determine the characteristics, risk factors and results of fall accident and to suggest the nursing strategies for prevention of fall. Data were collected by reviewing the medical records and interviewing with the fallers and their family members. For data analysis spss/pc+ program was utilized for descriptive statistics, adjusted standardized X2-test. The results of this study were as follows: 1) Total subjects were 412 fallers, of which 245 (59.5%) were men and 167 (40.5%) were women. Age were 0-14 years 79 (19.2%), 15-44 years 125 (30.4%), 45-64 years 104 (25.2%), over 65 years 104 (25.2%). 2) There was significant association between age and the sexes (X2 = 39.17, P = 0.00). 3) There was significant association between age and history of falls (X2 = 44.41, P = .00). And history of falls in the elderly was significantly associated with falls. 4) There was significant association with age and medical diagnosis (X2 = 140.66, P = .00), chief medical diagnosis were hypertension (34), diabetes mellitus (22), arthritis (11), stroke (8), fracture (7), pulmonary tuberculosis (6), dementia (5) and cataract (5). 5) There was significant association between age and intrinsic factors: cognitive impairment, mobility impairment, insomnia, emotional problems, urinary difficulty, visual impairments, hearing impairments, use of drugs (sedatives, antihypertensive drugs, diuretics, antidepressants) (P < 0.05). But there was no significant association between age and dizziness (X2 = 2.87, P = .41). 6) 15.3% of total fallers were drunken state when they were fallen. 7) Environmental factors of fall accident were unusual posture (50.9%), slips (35.2%), trips (9.5%) and collision (4.4%). 8) Most of falls occurred during the day time, peak frequencies of falls occurred from 1 pm to 6 pm and 7 am to 12 am. 9) The places of fall accident were roads (22.6%), house-stairs (16.7%), rooms, floors, kitchen (11.2%), the roof-top, veranda, windows (10.9%), hospital (7.5%), ice or snowy ways (5.8%), bathroom (4.9%), playground, park (4.9%), subway-stairs (4.4%) and public-bathrooms (2.2%). 10) Activities at the time of fall accident were walking (37.6%), turning around or reaching for something (20.9%), going up or down stairs (19.2%), exercise, working (17.4%), up or down from a bed (2.7%), using wheelchair or walking aids, standing up or down from a chair (2.2%) and standing still (2.2%). 11) Anatomical locations of injuries by falls were head, face, neck (31.3%), lower extremities (29.9%), upper extremities (20.6%), spine, thorax, abdomen or pelvic contents (11.4%) and unspecified (2.9%). 12) Types of injures were fracture (47.6%), bruises (13.8%), laceration (13.3%), sprains (9.0%), headache (6.6%), abrasions (2.9%), intracranial hemorhage (2.4%) and burns (0.5%). 13) 41.5% of the fallers were hospitalized and average of hospitalization was 22.3 days. 14) The six fallers (1.46%) died from fall injuries. The two fallers died from intracranial hemorhage and the four fallers died of secondary infection; pneumonia (2), sepsis (1) and cellulitis (1). It is suggested that 1) Further study is needed with larger sample size to identify the fall risk factors. 2) After the fall accident, comprehensive nursing care and regular physical exercise should be emphasized for the elderly person. 3) Safety education and safety facilities of the public place and home is necessary for fall prevention.

The aim of this study was to investigate the one-year developmental outcome of offspring of mothers with pregestational diabetes mellitus (PGDM). We prospectively evaluated 31 women with PGDM (21 with type 1 DM and 10 with type 2 DM) and 41 nondiabetic controls during pregnancy and for one year follow-up. Data showed that offspring of mothers with PGDM scored lower than controls in all aspects of development--mental, psychomotor, and exploration/orientation. Despite the good metabolic control of the mothers with PGDM, their offpsring showed a less favorable developmental outcome at one year than infants of nondiabetic mothers. MDI score and PDI score were significantly lower in the diabetic group than in the controls (91.04 vs 98.15, p<0.05 and 85.15 vs 95.54, p<0.05, respectively). In addition, the orientation/engagement score was lower in the diabetic group as compared with the nondiabetic group (41.04 vs 45.50, p<0.05). Whereas no significant difference was found between the type 1 and type 2 groups with regard to the MDI score, type 2 infants scored lower on the PDI than infants in the type 1 group (78.1 vs 89.3) but higher on the motor quality score (34.0 vs 31.3). These preliminary findings support the need for ongoing large scale developmental follow-up studies of offspring born to diabetic mothers in order to elucidate whether they have cognitive impairment later in life.

This article reviews evidence for the occurrence of atypical parkinsonism in Afro-Caribbean and Indian ethnic minority subjects living in western countries, particularly the UK. Current information on the frequency, pattern, and prevalence of Parkinson's disease and parkinsonism in these communities is unclear and controversial. While several workers have suggested that there is a low prevalence of Parkinson's disease in populations of African origin, other workers have suggested a higher prevalence of Parkinson's disease in African Americans. Furthermore, little information is available in relation to the pattern of parkinsonism in these subjects. A recent phenomenologic study of parkinsonism in the French West Indies by Caparros-Lefebvre and colleagues has indicated a significantly increased frequency of atypical parkinsonism in local non-white subjects. Since 1995, we have been studying the pattern and frequency of parkinsonism in Afro-Caribbean and Indian (originating from the Indian subcontinent) patients living in the UK, with London serving as the coordinating center. Our results indicate that there is a three- to fourfold increase in the frequency of occurrence of sporadic atypical parkinsonism characterized by levodopa hyporesponsiveness, bradykinesia-dominant disease, and early cognitive dysfunction in these patients even after exclusion of patients with clinically probable multiple system atrophy, progressive supranuclear palsy, and Lewy body dementia. These findings are similar to observations made in the French West Indies. Ongoing studies in India suggest that atypical parkinsonism also affects local patients, and the pattern of parkinsonism tends to differ from Afro-Caribbean subjects in the UK. Studies are currently underway to unravel the mechanism of increased frequency of atypical parkinsonism in these ethnic groups and include genetic studies addressing polymorphisms of enzymes metabolizing levodopa, dietary neurotoxin screen and functional imaging studies of the striatum using positron emission tomography. Furthermore, the contribution of diabetes mellitus and hypertension, commonly seen in these ethnic groups, is also being examined.

The pathophysiology of brain damage induced by severe hypoglycemia is still unknown. We experienced a case with type 1 diabetes and recurrent severe hypoglycemic coma who showed a central brain atrophy and an abnormal cerebrospinal fluid flow, suggesting normal pressure hydrocephalus. Following this case, the CSF flow was studied using 111In-DTPA cisternography in six consecutive diabetic patients admitted for repeated episodes of hypoglycemic coma. All the patients showed the central brain atrophy on computed tomography and four of them (67%) had the ventricular reflux, with delayed clearance of 111In-DTPA. Two patients with abnormal CSF flow showed cognitive dysfunction by WAIS or WAIS-R. In contrast, none of five randomly selected diabetic patients, without hypoglycemic coma showed abnormal CSF flow. Our results suggest the presence of normal pressure hydrocephalus in diabetic patients with recurrent hypoglycemic coma. It may associate with the cognitive dysfunction.

The neurological complications of cardiac surgery are associated with significantly increased mortality, morbidity and resource utilization. The use of new surgical techniques, introduction of wider indications for surgery and increased public expectation has led to an increase in the average age of cardiac surgical patients and an increased incidence of repeat procedures. With these changes has come an increased risk of neurological complications. The likelihood of perioperative stroke varies between 1% and 5% in most published series and is dependent on a multitude of risk factors. Of these, patient age, aortic atheroma, symptomatic cerebrovascular disease, diabetes mellitus and the type of surgery appear to be most important. Cognitive deterioration after cardiac surgery is far more common, affecting as many as 80% of patients a few days after surgery and persisting in one-third. Despite an increase in the age of the cardiac surgical population, the reported incidence of cognitive dysfunction after cardiac surgery seems to have fallen in recent years. Whether this is a real phenomenon or the result of changes in the use of psychometric testing and the definition of cognitive decline remains unclear. Recognition that certain equipment, surgical practices and patient factors contribute to neurological morbidity has prompted 'neuroprotective' interventions. Some of these (e.g. arterial line filtration and alpha-stat management) have been shown to improve outcome. Despite these measures, a small number of patients will inevitably sustain cerebral injury during otherwise successful cardiac surgery. Although pharmacological neuroprotection may, in the future, offer some of these patients an improved outcome, it is unlikely that any single agent will prevent neurological injury. In the meantime, the CNS complications of cardiac surgery remain a fertile area of research.

Type 2 diabetes is associated with an increased risk of cognitive dysfunction. These effects seem particularly true for memory functions. This article examines how diabetes and the biological changes that occur with diabetes such as hyperglycemia, changes in insulin concentration, hypertension, and changes in lipid levels might lead to these alterations in cognitive functioning, with an emphasis on the mechanisms leading to changes in memory.

Vision is not routinely tested when the health of older people is assessed, and the aim of this study was to detect older people with vision impairment for referral to appropriate eye care services. People admitted for assessment and or rehabilitation in three aged care assessment centres had distance and near visual acuity assessed with a simplified vision test. A pinhole test was used when necessary. Referral criteria were distance visual acuity of less than 6/12; near vision of less than N8, and people with diabetes who had not attended a dilated fundus examination in the last 2 years. Visual acuity results were obtained in 93% of patients (685/735). Those unable to perform the vision test were very ill or had severe cognitive impairment. Forty-three per cent of patients (266/646) had impaired vision and, of these, 70.6% (188/266) were referred to eye care specialists. Forty-five per cent were referred to ophthalmologists, 36% to optometrists and 20% to low vision services. This significant proportion of patients with poor vision suggests that vision screening is warranted.

Review of the literature on the cognitive correlates and consequences of Type 2 diabetes reveals two very intriguing findings. Not only are verbal learning and memory skills most likely to be disrupted as compared to other cognitive skills (e.g. attention, executive function; psychomotor efficiency), but these mnestic deficits appear to be restricted to individuals with diabetes who are older than 60-65 years of age. Middle-aged adults with either Type 2 or Type 1 diabetes are apparently protected insofar as researchers have only infrequently reported learning and memory impairments in that age group. Why do older adults have such an increased risk of diabetes-associated memory dysfunction? In our view, this phenomenon is a consequence of a synergistic interaction between diabetes-related metabolic derangements and the structural and functional changes occurring in the central nervous system (CNS) that are part of the normal ageing process. To critically evaluate that possibility, we summarise what is known about learning and memory dysfunction in the adult with diabetes, examine the extent to which chronic hyperglycaemia may adversely affect the integrity of the CNS, and selectively review the literature on age-associated changes in brain morphology and cognitive function, paying special attention to the threshold theory of cognitive impairment.

We describe the prevalence of cognitive impairment in a population of community-living older people, its association with functional decline, and degree of comorbidity. In addition, we examined the relationship between different levels of cognitive impairment and mortality. We conducted an observational study of 1787 patients aged 65 years and above with any degree of cognitive impairment. Patient data were collected with the Minimum Data Set for Home Care. More than 50% of patients had some level of cognitive impairment, which correlates with the degree of physical frailty. On the contrary, patients with cognitive impairment appear to have fewer comorbid conditions and are less likely to receive medications than patients with normal cognitive status. In particular, hypertension, congestive heart failure, chronic obstructive pulmonary disease, cancer, diabetes mellitus, and osteoporosis are found more frequently among patients with normal mental status compared with those showing some level of cognitive defects. Yet, more severe cognitive impairment is associated with a higher mortality rate. Demented patients are characterized by a high prevalence of functional disability and by increased mortality. This increased morbidity and mortality rate is associated with a lower prevalence of comorbid clinical conditions and drug use, relative to patients with normal cognitive performance. The present findings support the possibility that severe cognitive impairment has an independent effect on survival.

Delusions associated with cerebrovascular diseases have been sporadically reported. Although both psychiatrists and neurologists attempted to link delusions with anatomical locations of the brain lesion, comorbid psychiatric and neurological disorders make the interpretation of delusions difficult. The purpose of the present paper is to report the clinical features and magnetic resonance imaging (MRI) characteristics in patients with delusional disorder due to diffuse cerebrovascular diseases, and to redefine the concept of 'vascular delusion'. The clinical features and MRI findings were reviewed retrospectively in a series of seven patients with 'delusional disorder due to cerebrovascular disease' as defined in Diagnostic and Statistical Manual of Mental Disorders (DSMIV). The average age of onset is 64. No patient had a prior personal or family history of major psychiatric illness. The illness is presented as acute, subacute or stepwise course. Hypertension was present in all patients. Two had diabetes mellitus, and one had atrial fibrillation. Three had clinical evidence of previous cerebrovascular attacks, only one showed minor neurological deficits. Three had diffuse cortical slow wave in electroencephalogram. No patient had significant cognitive impairment but had multiple cortical and subcortical cerebrovascular lesions in MRI, with white-matter lesions (WML) in bilateral frontal areas. Delusional disorder due to diffuse cerebrovascular change is characterized by late-onset, stepwise course, and comorbid medical and neurological diseases. The results of vascular changes in the present study did not establish a cause-effect relationship and should be considered as multifactorial in pathogenesis. The findings suggested the hypothesis of neural circuit theory. Further studies in larger numbers of patients and newer neuroimaging techniques are needed to expand the knowledge learned from these findings.
