Consistent mapping and automatic visual search: comparing persons with and without intellectual disability.

BACKGROUND: Merrill et al. (1996) reported that persons with intellectual disability (ID) were slower at learning a visual search task to automaticity relative to persons of the same age without ID. For persons without ID, automaticity develops most rapidly under conditions in which a response is always the same for a particular stimulus. This study was designed to investigate whether persons with and without ID are differentially sensitive to the influence of consistently mapped versus inconsistently mapped stimulus responses. METHODS: The primary manipulation was the consistency between a particular stimulus and the response to that stimulus in a visual search task. Sixteen participants with ID and 16 without ID searched displays of two, three, or four pictured objects to determine if a target was present. For half of the participants, the targets were always targets. For the other half, the targets became nontargets on 25% of the trials. RESULTS: Analyses focused on changes in response times associated with set size. Because automaticity allows for parallel processing, the elimination of significant effects of set size was taken as an index of the development of automaticity. Results indicated that inconsistent mapping significantly slowed the development of automaticity for the participants without ID but not for the participants with ID. DISCUSSION: Results were discussed in terms of the role of inhibition processes in the development of automatic search and detection. The effectiveness of inhibition processes was compromised by the consistency manipulation. The effect of the consistency manipulation was greater for the participants without ID because they were presumed to be using inhibition processes more effectively during practice than did the participants with ID.

The prevalence of Helicobacter pylori infection among inhabitants and healthy employees of institutes for the intellectually disabled.

OBJECTIVES: The prevalence of Helicobacter pylori infection varies in the Netherlands from 5% in children to about 50% in the elderly. In the institutionalized intellectually disabled, a high prevalence of infection has been reported. It is unknown whether there are specific risk factors to obtain H. pylori infection in this population, and whether employees of such institutes are at risk for H. pylori infection. METHODS: Therefore, we analyzed the seroprevalence of H. pylori antibodies by ELISA among 338 intellectually disabled inhabitants and 254 employees of two institutes. H. pylori-positive patients were compared with H. pylori-negative controls. The intellectually disabled and the employees were evaluated for possible risk factors. RESULTS: Of the 338 intellectually disabled, 280 (82.8%, median age 51 yr) were infected with H. pylori. This rate is significantly higher than the prevalence of H. pylori in the Dutch population. The presence of H. pylori was significantly associated with male gender, longer duration of institutionalization, an IQ < 50, rumination, and a history of upper abdominal symptoms. Of the 254 employees, 69 (27.2%) were infected, which is equal to the rate for the total Dutch population. The presence of H. pylori infection among employees was, however, significantly associated with a higher level of physical contact with the intellectually disabled, longer duration of employment, and having upper abdominal symptoms. CONCLUSIONS: Intellectually disabled persons are at high risk of developing H. pylori infection. Employees with close physical contact to the intellectually disabled population for a considerable period of time are also at increased risk. H. pylori infection should be considered a job attributable risk in this profession.

Dental erosions and gastro-oesophageal reflux disease in institutionalized intellectually disabled individuals.

OBJECTIVE: Both exogenous acids, from the diet, and endogenous acids, from stomach juice, can dissolve the enamel mineral, resulting in dental erosions. Gastric acid may reach the mouth by gastro-oesophageal reflux disease (GERD), recurrent vomiting, rumination and regurgitation. These conditions are frequently found in the intellectually disabled population. Therefore, we investigated the presence of dental erosions in combination with GERD among intellectually disabled inhabitants, with an IQ < 50, taken from three Dutch institutes. MATERIALS AND METHODS: At random 63 individuals underwent an oesophageal pH test and dental screening and possible predisposing and attributable factors were determined. An abnormal pH level was defined as a pH < 4, > 4.5% of the measured time. Subjects with dental erosions were compared to those without dental erosions. RESULTS: In 29 out of 63 (46.0%) cases evidence of dental erosions was found. In 19 of these 29 subjects with erosions (65.5%) GERD was diagnosed, compared to nine (26.5%) out of 34 subjects without erosions (P = 0.04). In the subjects with erosions mean duration of pH < 4 was 15.6% (range: 0.5-90.5) compared to 6.3% (range 0-40.4) in subjects without erosions (P = 0.02). An IQ < 35 was found to be predisposing (P < 0.001). CONCLUSION: In this population of 63 institutionalised intellectually disabled persons dental erosions were diagnosed in 46%. Sixty-five per cent of them had GERD. Individuals with longer duration of pH < 4 than 6.3% of the measured time and with an IQ < 35 were at higher risk to develop dental erosions. This study shows that dental erosions in the intellectually disabled population might be an oral manifestation of GERD.

Move of adults with intellectual disability from institutions to community-based living: changes of food arrangements and oral health.

The policy of deinstitutionalisation, integration and increased independence for individuals with intellectual disability has been accepted in the western part of the world. The aim of the present study was to evaluate the changes in oral health and eating arrangements when intellectually disabled persons move from an institution to integrated living. In 55 subjects the incidence of caries and tooth mortality was compared 4.7 years before and after the change in living arrangements. In addition, changes in oral hygiene routines, eating arrangements and weight were registered. The incidence of caries and tooth mortality was low among individuals with severe and moderate intellectual disability during 4.7 years before as well as after de-institutionalisation, and no differences could be observed between the periods. After 4.7 years of integrated living, 40% of the subjects were estimated to have gained weight. Among those subjects with an estimated decreased weight (13%), the caries incidence was higher compared to other subjects with intellectual disability. Participation in grocery shopping and cooking increased in the integrated living. The increase in weight suggests an impact on general health after almost 5 years of integrated living. No indications of a corresponding influence on oral health in individuals with severe or moderate intellectual disability could be observed after deinstitutionalisation. However, oral health in weight-losing subjects need further investigations.

Intellectual disability and parenthood.

Parenthood in persons with intellectual disability (ID) is an issue of concern for the family, guardians, and professionals as there are many sentiments and problems involved: financial, technical, medical, legal, and above all moral. People with intellectual, developmental, or other disabilities have feelings, want relationships, and are able to have children also. The attitude of society has changed through time from the early eugenic concern with heredity and fertility, to a focus on the risk to the children due to parental neglect or abuse, to acceptance and a search for solutions to parental training and support. This change can be seen as a result of a shift from institutional care to community care and normalization. This paper reviews available research, prevalence, service issues, experience from around the world, and relates to the situation in Israel. Jewish Law has been very progressive regarding the possibility of marriage between persons with ID (in contrast to American Law where historically this right has been denied, until recently). Recent research has shown that, in the case of such a union resulting in children, although they require some supervision, family, friends, and social welfare agencies have scrutinized these families so much they are in constant fear of their child being taken away. There is little information on the number of such cases and an overall dearth of information on the effects on the children, although one recent study from the U.K. has shown a varied picture of resilience and a close, warm relationship later on with the family and especially the mother.
