The Bronx Aging Study is a longitudinal investigation of nondemented, nonterminally ill, community-residing, old old volunteer subjects, designed to assess risk factors for the development of dementia and coronary and cerebrovascular diseases. During the first five annual evaluations, total cholesterol, high-density (HDL) and low-density lipoprotein (LDL), and triglyceride levels were measured. Mean cholesterol values (+/- standard error of the mean) for subjects at baseline were significantly higher for women than for men. Respectively, the values for total cholesterol were 6.1 +/- .1 mm/L (234 +/- 3 mg/dL) and 5.3 +/- .1 mm/L (207 +/- 3 mg/dL); for LDL cholesterol, 4.1 +/- .1 mm/L (158 +/- 2 mg/dL) and 3.7 +/- .1 mm/L (141 +/- 3 mg/dl); and for HDL cholesterol, 1.2 +/- .1 mm/L (47 +/- 1 mg/dL) and 1.0 +/- .1 mm/L (38 +/- 1 mg/dL). Mean triglyceride levels were 1.5 +/- .1 mm/L (135 +/- 5 mg/dL) for women and 1.6 +/- .1 mm/L (138 +/- 5 mg/dL) for men. Further, mean values remained stable over time. However, there was considerable intraindividual change observed in a substantial proportion of subjects between initial and final determinations. Changes of at least 10% from baseline were observed in 41%, 63%, 52%, and 78% of the cohort for cholesterol, HDL, LDL, and triglycerides, respectively. Thus, single measurements appear inadequate for establishing a diagnosis of hyperlipidemia in the elderly.

We investigated the anticardiolipin antibody (ACA) in a series of patients with cerebral infarction without systemic lupus erythematosus (SLA). Clinical and laboratory data were assessed from a series of 250 non-SLE patients with cerebral infarction who visited our clinic from 1988 to 1990. The concentration of anticardiolipin IgG antibody was measured by an enzyme-linked immunosorbent assay technique. An elevated ACA level was defined as one which was greater than 3 standard deviations above the mean level for normal controls. We examined the CT findings and risk factors for stroke such as hypertension, diabetes mellitus, hyperlipidemia and cardiac disease. Laboratory data such as the platelet count, the presence of lupus anticoagulant and a biologic false-positive test for syphilis were also investigated. Among the 250 patients with infarction, IgG ACA was detected in 22 (8.8%). There was no significant difference in incidence of ACA between the patients with cerebral thrombosis and those with cerebral embolism. On CT scan, multiple cerebral infarcts were noted in 18 of the 22 patients. As regards the location of the infarct, the cerebral cortex together with the basal ganglia was more common than isolated lesions of the cortex or basal ganglia. Concerning the risk factors for stroke, hypertension was noted in 12, diabetes mellitus in 2, hyperlipidemia in 2 and cardiac disease in 2. Lupus anticoagulant and thrombocytopenia were not detected in any of the cases. A biologic false-positive test for syphilis was observed in one case. Dementia was present in 12 of the 22 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Cerebrotendinous Xanthomatosis (CTX) is a rare familial disease characterized by tendon-xanthomas, cataracts, progressive cerebellar ataxia, dementia and an elevation of serum cholestanol with normal levels of cholesterol. Although the pathogenesis of CTX is not fully understood, increment of cholestanol is suggested one of the major metabolic derangements of the disease. Recently, the LDL-apheresis has been developed as a new therapeutical equipment in the field of hyperlipidemia and been widely used to reduce the levels of LDL-cholesterol by selective LDL adsorption. From the point of view that cholestanol is involved mainly in LDL-cholesterol (1.019 less than d less than 1.063), we used this LDL-apheresis in the aim of reducing the cholestanol in 58 years old woman with typical sign and symptoms of CTX. The levels of serum cholestanol and cholesterol before the treatment with LDL-apheresis, were 10.7 micrograms/ml and 175 mg/dl respectively. Also the ratio of cholestanol/cholesterol indicated 0.63. By the first procedure of apheresis, the level of cholestanol was markedly decreased to 5.2 micrograms/ml (50%). Several LDL-apheresis treatments were carried out once a month. During 5 months treatments, neurological deterioration was arrested, dementia which included disorientation and recent-memory loss, cleaned a little. Although the xanthomas did not decrease in size, this patients was better oriented to person, place, time and was able to speak rationally, 2nd her cerebellar dysfunction revealed improvement. From our new experiments-we believe that the LDL-apheresis offers the strong hope of preventing the progress on cerebrotendinous xanthomatosis.

Dementias which are either reversible or avoidable are discussed in the light of the literature. The frequency is between 6 and 32%. The most important etiological groups are immunological vasculopathies, hyperlipidemia, some types of encephalitis and, mainly, progressive dementia of the insane, benign tumors and in particular meningioma, low pressure hydrocephalus, intoxications due to drugs, industrial products and alcohol, metabolic disturbances, encephalopathy in dialysed patients, ileo-jejunal-bypass encephalopathy and encephalopathy due to neoplasms. Dementias are also seen in endocrinological disturbances and particularly in hypothyroidism. Vitamin B12 and folate deficiency, as well as epilepsy, may be causes of dementia. Depression may mimic a state of dementia. Some features of reversible dementias are listed, including in particular the somewhat more rapid onset, the younger age of patients, and accompanying neurological symptoms such as headache, gait disturbances, ataxia, polyneuropathy, myoclonus or epileptic fits.

In order to evaluate the prevalence of common and/or internal carotid stenoses together with metabolic abnormalities in dementia nineteen patients were investigated. Dementia and differential diagnosis between Alzheimer type (DAT) and multi-infarctual (MID) dementia were performed on the basis of Computerized Tomography scan, behavioural anamnesis, neurological and neuropsychological examinations. Eight patients were diagnosed as MID and 11 as DAT. Noninvasive study of neck arteries was performed in supine position by a Duplex Scanner, able of detecting a wide range of stenosis, even when very mild. Arterial hypertension, hyperlipidemia, diabetes and high hematocrit level were present in both groups, although to a higher extent in MID (p 0.05). Results from Duplex Scanner demonstrate 12 vascular stenoses 16-49% and one between 50-99% (13/76), being vascular abnormalities equally distributed among DAT and MID patients. These data suggest that patients with metabolic abnormalities and arteriosclerosis can develop dementia not necessarily of vascular type. On the other hand, MID patients do not present higher number of stenosis as compared to DAT, indicating that vascular disease of carotid arteries is not prominent in the clinical context of dementia.

We compared the incidence of risk factors (such as hypertension, diabetes mellitus, hyperlipidemia, hematocrit, atrial fibrillation) and local cerebral blood flow between patients with lacunar infarction associated with leukoaraiosis (LA) in the centrum semiovale (LACS) and those with periventricular white matter lesions (PVWMLs) on magnetic resonance imagings (MRI). Only atrial fibrillation was more frequently seen in LACS (p < 0.05), but the incidence of other risk factors for cerebrovascular disease was not different between the two patient groups. Demented patients were older than those with preserved intelligence in both groups. Local cerebral blood flow was compared between patients with and without dementia by single photon emission computed tomography using N-isopropyl-p-123I iodoamphetamine (IMP). The cerebral: cerebellar IMP uptake ratio (%) was used as a measure of relative cerebral perfusion. Compared with normal controls the demented patients with PVWMLs showed a significant reduction in local cerebral blood flow in the parietal area (p < 0.05) and the basal gray region (p < 0.05), and those with LACS in the frontal area (p < 0.05) and the basal gray region (p < 0.05). A significant positive correlation was found between local cerebral blood flow and dementia rating scales in the temporal and parietal areas in PVWMLs, and in the frontal area in LACS. These results suggest that most patients with LACS may represent vascular dementia of Binswanger type, and some demented patients with PVWMLs may have Alzheimer type dementia.

Vascular dementia is a clinical syndrome of acquired intellectual impairment resulting from brain injury due to a cerebrovascular disorder. It is a complex diagnosis, and diagnostic criteria vary. In community practice, the physician can probably make the diagnosis based on the history and medical examination. CT demonstration of one or more infarcts increases the likelihood of this diagnosis. Hypertension is a major risk factor for vascular dementia. Others include smoking, hyperlipidemia, atrial fibrillation, diabetes, and a sedentary lifestyle. Cerebrovascular disease is an important cause of cognitive decline in older patients. Therefore, it is important to recognize risk factors for stroke and institute measures for prevention.

Vascular dementia is seen much more often in people at age 85 than in those between the ages of 55 and 75. The differential diagnosis includes Alzheimer's disease and mixed dementia. The classic criteria for vascular dementia--stepwise deterioration and focal neurologic signs--are important, as focal neurologic signs usually don't occur in Alzheimer's disease. Identifying a significant number of points on the Hachinski scale, including hypertension, can help make a diagnosis of vascular disease. For more effective differential diagnosis, CT or MRI can be useful. However, not all clinicians are convinced of the necessity of imaging, as long as stroke risk factors such as hypertension and hyperlipidemia are managed for all older patients.

Paraoxonase activities (322 healthy subjects) measured in the absence of ethylenediaminetetraacetic acid (EDTA) had a polymodal distribution profile with 60% of the subjects in the low activity mode; the activity measured in the presence of EDTA had a unimodal skewed distribution. Cholinesterase (ChE) activities (365 healthy subjects) had a unimodal, slightly skewed distribution. Patients with dementia (74) and patients with hyperlipidaemia (159) had different median paraoxonase and ChE activities than healthy subjects and all activity profiles had a higher skewness. The ChE variants usual (UU), fluoride resistant (FS) and atypical (AA) had the same affinity for the studied charged and uncharged ligands. The variants differed in rates of inhibition by the charged organophosphates and carbamates.
