Feeblemindedness, dementia, mental disorders, and epilepsy, as well as optic atrophy, tapeto-retinal degenerations, cataract, ophthalmoplegias, and neural hearing loss were found more frequently in patients suffering from hereditary ataxias (HA) and allied disorders than in the general population. Mental disorders and squints, and in certain instances also ocular myopathy, feeblemindedness, and cataract were found also in non-HA family members. These traits were particularly frequent in subjects with minor neurological signs previously defined as having an "unspecific neuropathy" (Un), and belonging to kindreds in which autosomal dominant HA segregated. Un clustering in such families is probably caused by other genetic (or other) mechanisms different from that governing the classical HA in the family. These presumably polygenic conditions are thought to be introduced into the HA kindreds by a negative selection. Optic atrophy, tapeto-retinal degenerations, surdity, epilepsy, and possibly also dementia, were found together with monomeric disease, as well as in the Un subjects, particularly in families with recessive HA. Such traits were equally rare in unaffected family members and controls. Un in such families as well as the traits mentioned may reflect manifestation of HA genes in heterozygotes. They could also reflect the presence of genes linked to the HA genes.

The connection between memory and learning with vision was investigated by studying 100 cataract operation patients, aged 71 to 76 years, 25 of them being men and 75 women. The cataract operation restored sufficient acuity of vision for reading (minimum E-test value 0.40) to 79% of the subjects. Short-term memory was studied with series of numbers, homogenic and heterogenic inhibition, and long sentences. Learning was tested with paired-associate learning and word learning. Psychological symptoms were measured on the Brief Psychiatric Rating Scale and personality on the Mini-Mult MMPI. Memory and learning improved significantly when vision was normalized after the cataract operation. Poor memory and learning scores correlated with monocular vision before the operation and with defects in the field of vision, due to glaucoma and exceeding 20%, postsurgery. Monocular vision and defects in the visual field caused a continuous sense of abnormalness, which impaired old people's ability to concentrate on tasks of memory and learning. Cerebrovascular disturbances, beginning dementia, and moderate psychological symptoms obstructed memory and learning on both test rounds. Depression was the most important psychological symptom contributing to poor memory and learning scores after the cataract operation. The memory and learning defects mainly reflected disturbances in memorizing.

Most elderly persons with dementia are cared for at home, usually by the spouse or an adult child. The objective of the present study was to determine whether there is an excess of psychological and physical health problems among family caregivers (CGs) of elderly persons with dementia. Data were obtained by interview from close family members of dementia patients (CGs), and from a comparison group made up of close family members of patients undergoing cataract surgery (non-caregivers, NCGs). CGs had significantly higher levels of depression and physical symptoms than NCGs. The association between caregiving and the health variables was stronger among subjects who were the patient's spouse than among those who were the patient's child. Furthermore, greater behavioral disturbance in the demented patient was associated with higher levels of morbidity in the CG. The results suggest that CGs might benefit from careful monitoring of their health status, and from greater access to specialized support services.

The senescence accelerated mouse (SAM) has recently been characterized as a unique model to investigate age-related disorders, including amyloidosis, cataract, osteoporosis and dementia. However, little is known as to the properties of the lung in these animals. Tobacco smoke is also associated with enhanced loss of elastic recoil and the development of emphysema. We have attempted to examine morphological as well as biochemical changes of the distal lung in SAM-P/2, as the senescence-prone series and SAM-R/1, as the senescence-resistant series. The animals were intermittently exposed to tobacco smoke or air by Hamburg II machines for 5 weeks. Then both groups of animals were killed for histologic and biochemical study. Compared with SAM-R/1, SAM-P/2, even with air exposure, showed a higher value of the mean linear intercept without alveolar wall destruction. It became even greater due to tobacco exposure with emphysematous change. Tobacco exposure accumulated inflammatory cells into alveoli in SAM-P/2, but not in SAM-R/1. Oxygen radical generation by those cells was also higher in SAM-P/2. Analysis of bronchoalveolar lavage fluid in SAM-P/2 after tobacco exposure disclosed increases in albumin content, total protein content and elastase-like activity. There were decreases in the ratio of elastase inhibitory capacity (EIC) to trypsin inhibitory capacity (TIC), contents of glutathione and total free thiol groups. Moreover, SAM-P/2 showed significantly lower EIC/TIC ratio in serum, even with air exposure, than that of SAM-R/1. These results indicate that SAM-P/2 can be a good model for the study of natural evolution of the aging lung as well as its susceptibility to tobacco smoke in the development of emphysema.

The authors report three observations of cerebro-tendinous xanthomatosis (CTX). The three patients presented tendinous xanthoma and cataract. The neurologic disorders were different in each case. The first one, a 43 years old woman suffered from dementia, ataxia and pseudobulbar palsy: CT scan showed cerebellar hypodense lesions. After the apparition of bulbar signs ans cachexia she died at 45. The second patient, a 39 years old man had an ataxia and mild psychiatric disorders. He was stabilized with a treatment of chenodesoxycholic acid. The third one, a 49 years old women suffered only from tendinous xanthoma, cataract, and had no neurological disorder. His plasmatic cholestanol level was high. CTX is a recessive deficit of the hepatic 26 hydroxylase with deposits of abnormal metabolites in tendons, crystalline lenses and central nervous system. Reviewing the 44 observations of CTX in the literature, the authors define the genetical, clinical, biochemical and therapeutical aspects of CTX, and underline the necessity of a early diagnosis with cholestanol dosage, before the apparition of neurological disorders and the short terminal phase. CTX is a rare but fortunately treatable neurolipidosis.

The population aged 85 years or over (n = 674) living in Tampere, Finland was surveyed in 1977-78. Altogether 561 persons (83%), 99 men and 462 women, were examined. A re-examination of 170 persons, 23 men and 147 women, was carried out in 1982 by the same procedure as in 1977-78, The results were compared with those of the same people and with those of over-90s five years before. Of the group followed, in the initial survey 65% were living at home and 25% in old people's homes, 10% being hospitalized. The percentage of hospital in-patients had increased threefold during the five-year follow-up. The functional capacity of the subjects had deteriorated as regards mental function and ability to walk. The mean values of blood samples (apart from ESR) were still in normal ranges, although the levels of haemoglobin and haematocrit had fallen significantly. Dementia or confusion, anaemia, femoral-neck fracture and cataract were significantly increased.

Norrie's disease is an X-linked disease presenting bilateral blindness at birth or during the first few months of life. A white retrolental membrane is seen initially, later the eyes usually become phthisic. Dementia or psychosis appears in about 25% and sensory hearing loss present in 1/5 or 1/4 of the blind males. Carriers are clinically unaffected. The main differential diagnoses comprise retinoblastoma, retrolental fibroplasia, toxoplasmosis, falciform detachment, juvenile retinoschisis, sex-linked microphthalmia, sex-linked cataract and congenital retinal detachment.

Cerebrotendinous xanthomatosis is an unusual disease, clinically characterized by dementia, cataracts, progressive cerebellar ataxia, pyramidal signs, and multiple xanthomas of tendons and other tissues. It was first described in 1937, and in 1968 the storage of cholesterol and cholestanol in the tissues was demonstrated. About 30 cases have been reported. The authors of the present communication report 2 cases in siblings with parental consanguinity. They showed mental impairment and cataract, and multiple xanthomas; in 1 case, pyramidal signs were detected in the 4 limbs associated with a rise of the vibration sense thresholds in the feet. The diagnosis was confirmed in both cases by greatly increased cholestanol levels in the blood serum, bile and in a tendon xanthoma. Cholesterol concentrations in the blood serum and bile were normal although increased in the xanthoma. One case had a gallstone. Computerized tomography showed hyperdense nodules in the cerebellar hemispheres of one patient, and a calcified parietal nodule in his sister. The etiopathogenesis of the disease is discussed. Treatment with ursodeoxycholic acid is in course in both patients.

Visual function of an institutionalized population with intellectual disability, consisting of 70 subjects with a mean age of 70.1 (range 60-92) years at initial evaluation, was assessed during a 10-year prospective longitudinal study. One subject had Down's syndrome and could not be assessed as a result of dementia. Lower visual acuity values were relatively overrepresented as compared to reported data from ageing populations without intellectual disability. In addition, the prevalence of moderate to severe visual impairment was distinctly higher (27.9% in the group studied vs. 0.66% at age 60-69 years to 13% over age 80 in a population without intellectual disability). During follow-up, visual function improved in three out of 61 subjects (4.9%) after cataract surgery, and deteriorated in eight out of 61 subjects (13.1%), even with optimal correction, as a result of cataract and macular degeneration. Causes of excess impairment were congenital or childhood conditions, too-late diagnosis of glaucoma and suboptimal correction of refractive errors in non-cooperative individuals. The present author concludes that it should be possible to reduce excess impairment by an active diagnostic and therapeutic attitude to subjects from a young age onwards.

The objective of this study was to describe the health problems of a group dementia patients on admission and during residence in a Dutch nursing home and to compare these with figures of patients of 75 years and over from general practice. In 890 nursing home patients suffering from dementia prevalence of health problems on admission and the incidence during the residence were classified by means of the ICHPPC-2-defined. The differences between men and women were studied as was the influence of the season on the incidence during the stay. Results were compared with figures of patients of seventy five year and over from the continuous morbidity registration (CMR) from 'Nijmegen'. The most frequently occurring health problems on admission were: varicose veins of legs, acquired deformation of the spine, presbyacusis, hypertension, arthrosis, COPD, cerebrovascular disorders, heart murmur, cataract and chronic ischemic heart disease. During the residence the following health problems were frequently diagnosed: urinary tract infection, side effect of medicine, constipation, pneumonia, pressure sore, feeding problem, contusion, heart failure, cold and conjunctivitis. There were clear differences between men and women. Especially the incidence of intercurrent diseases showed great differences from the patterns in general practice. Prevalence of health problems on admission to the nursing home home agreed mor with figures from general practice. Respiratory tract infections frequently occurred in winter and urinary tract infections, pressure sores and conjunctivitis seemed to occur more in the summer. Nursing home patients with dementia have a lot of chronic and intercurrent health problems. They differ clearly from patients in general practice.(ABSTRACT TRUNCATED AT 250 WORDS)
