BACKGROUND Although the evolution of the prevalence of cerebral palsy is now well documented, much less is known about the evolution of the prevalence of other disabilities such as mental retardation, sensorial defects, autism and psychosis. The aim of this paper is to determine those trends. METHODS A population-based survey was carried out in 1992-1993 in three French 'départments'. All dis...

Mental retardation is a general decline in intellectual function that occurs during childhood development and associated with impaired social adaptation. The purpose of this study was to determine the relationship between knowledge parenting styles parents on children mental retardation. research method descriptive cross sectional approach. data collection technique used total sampling 44 respo...

New computerized techniques allow the precise measurement of psychomotor retardation in patients with a major depressive episode (MDE). One such technique is the analysis of writing and drawing behaviour during figure copying tasks. In the present study, 22 inpatients with an MDE were compared to 22 normal controls. Three tasks were used: the drawing of lines and simple figures, the copying of ...

the changes in viscoelastic properties of potatoes (tubuls agria) stored at 4 ˚c for 4 months were modeled and evaluated by using the creep-recovery test. cylindrical specimens with 15 mm in diameter and 35 mm long were used. the samples were allowed to deform gradually under the constant stress (110 kpa) for about 30 min. after removing the load, the sample recovery was registered. deformation...

We investigated the cause of mental retardation in 337 individuals seeking healthcare services at the Yokohama City Social Welfare Center for Disabilities during a period of a year and a half, from October 1987 to March 1989. The total number of participants in the study was 337 and consisted of 207 males and 130 females. Age ranged from 14 to 58 years with an average age of 22 years. IQ was ev...

background chromosomal aberrations are one of the most common causes of mental retardation (mr). objectives in this study, in order to identify the rate of chromosomal abnormalities in idiopathic mr, 50 mr patients at a charity center in hamadan, iran, were investigated. methods fifty mentally retarded male patients without specific chromosomal abnormalities (e.g., down syndrome, fragile x synd...

In children's mental retardation, sometimes the child's parents cannot directly consult with a psychiatric specialist because of limited time in carrying out activities hospital and high cost. Advances expert systems can overcome this problem, namely by designing web-based computer system that is integrated databases programming languages ​​such as PHP-MySQL so it help patients retardation to d...

Aquifer heterogeneity controls spatial and temporal variability of reactive transport parameters and has significant impacts on subsurface modeling of flow, transport, and remediation. Upscaling (or homogenization) is a process to replace a heterogeneous domain with a homogeneous one such that both reproduce the same response. To make reliable and accurate predictions of reactive transport for ...

Six years ago I asserted in print, with some sense of daring, that it was time to admit that the term mental retardation was a myth, a " false and unhelpful categorization of people with very diverse needs and characteristics " (Smith, 2002, p. 64). I quoted from Thomas Ssasz's (1960) classic work, The Myth of Mental Illness, and described the term mental retardation as being " scientifically w...
