Low-functioningA term used by some specialists to describe cases of autism where the individuals' full-scale IQ score is below 70, i.e. in the disabled range. This is not a formal diagnostic category, but rather a term sometimes used informally in diagnosis as well as in everyday situations and research. See also high-functioning. | |

Magnetic Resonance Imaging (MRI)A widely used brain imaging technique that passes magnetic currents harmlessly through the brain to reveal the structural anatomy, and how particular regions may be altered (e.g. larger or smaller than is typical) in conditions such as autism. | |
MeltdownAn intense response to overwhelming situations which can look like a temper tantrum. An autistic person may shout, cry or scream, kick, lash out or bite, or a combination of these, as a way to express their distress, stress or anxiety. | |
Mental statesRefers to a person’s beliefs, memories, desires, intentions and feelings. | |
Multiple-baseline studyA study, usually with a small number of participants, often in the same setting, who start the intervention after having been observed beforehand for differing lengths of time. For example one may start the intervention after 3 weeks, one after 5 weeks and one after 7 weeks. If each is seen to respond positively to the intervention this provides evidence that it is effective and the changes seen are not due to another factor. | |
Multiplex familiesFamilies with more than one child/family member on the autism spectrum. The fact that autism quite commonly affects several family members provides strong evidence that genetic factors play a role in causing autism. | |
Multiplex FamilyFamilies that have more than one Autistic person. | ||
MutationsChanges in the sequence of units making up the genes in a person’s DNA. Sometimes parts of a gene may become duplicated, deleted or changed in other ways. Such genetic variation will affect the proteins that are coded for by the DNA, influencing how parts of the body, including the nervous system develop, with consequent effects on behaviour or traits. | |

National Autism Plan for Children (NAPC)A UK framework for the identification, assessment, diagnosis and access to early interventions for pre-school and primary school aged children with autism spectrum conditions. | |
