F78.8: Other mental retardation : other impairments of behaviour

Intelligence involves various mental abilities. Intelligence can be assessed using certain tests. These are called intelligence tests or IQ tests. To take in and use new knowledge, we need mental abilities. These include the abilities to speak, to concentrate, and to memorize things. Under certain circumstances the mental abilities may not develop properly. You may then have difficulties in dealing with other people. Movements may also be changed.

It may be difficult to test your mental abilities.
