Definition: An ill-defined disorder of uncertain nosological validity. The category is designed to include a group of children with severe mental retardation (IQ below 35) who show major problems in hyperactivity and in attention, as well as stereotyped behaviours. They tend not to benefit from stimulant drugs (unlike those with an IQ in the normal range) and may exhibit a severe dysphoric reaction (sometimes with psychomotor retardation) when given stimulants. In adolescence, the overactivity tends to be replaced by underactivity (a pattern that is not usual in hyperkinetic ...[+++]children with normal intelligence). This syndrome is also often associated with a variety of developmental delays, either specific or global. The extent to which the behavioural pattern is a function of low IQ or of organic brain damage is not known.

Belongs to the group of multiple congenital anomalies/mental retardation syndromes with intellectual deficit, distinctive facies (upward slanting palpebral fissures, squint), kyphoscoliosis, diastasis recti, cryptorchidism, and a congenital heart def

Definition: A type of pervasive developmental disorder that differs from childhood autism either in age of onset or in failing to fulfil all three sets of diagnostic criteria. This subcategory should be used when there is abnormal and impaired development that is present only after age three years, and a lack of sufficient demonstrable abnormalities in one or two of the three areas of psychopathology required for the diagnosis of autism (namely, reciprocal social interactions, communication, and restricted, stereotyped, repetitive behaviour) in spite of characteristic abnormalities in the other area(s). Atypical autism arises most often in profoundly retarded individuals and in individuals with a severe specific developmental disorder of re ...[+++]ceptive language. | Atypical childhood psychosis Mental retardation with autistic features

Definition: Persistent eating of non-nutritive substances (such as soil, paint chippings, etc.). It may occur as one of many symptoms that are part of a more widespread psychiatric disorder (such as autism), or as a relatively isolated psychopathological behaviour; only the latter is classified here. The phenomenon is most common in mentally retarded children and, if mental retardation is also present, F70-F79 should be selected as the main diagnosis.

The problems above have not been solved by phasing out only two groups of brominated flame retardants (PBDE and PBB) to date.

The current RoHS Directive, adopted in 2003, based on a proposal made in 2000, sought to phase-out a first series of hazardous substances in EEE, namely certain heavy metals and two groups of brominated flame retardants.

The six hazardous substances being banned are the heavy metals lead, cadmium, mercury and hexavalent chromium, as well as two groups of brominated flame retardants, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).

Four heavy metals and two groups of brominated flame retardants are being banned as they can pose a direct risk to workers' health when waste electrical and electronic equipment is recycled and can be released into the environment when such waste is incinerated or disposed of in landfill dumps'.
