Findes Talblindhed?

Talblindhed har i mange år været anerkendt af Verdenssundhedsorganisationen WHO i ICD-10 under F81.2 (ordblindhed står under F81.0). Dette står for International Statistical Classification of Diseases and Related Health Problems – et katalog over alle officielle diagnoser. Danmark er medlem af WHO, og altså er talblindhed anerkendt her i landet. Du kan finde beskrivelser fra DSM-IV og ICD-10 her. Desværre på engelsk – den danske oversættelse kommer snart.

WHO ICD 10 F81.2 – Specific disorder of arithmetical skills

The International Statistical Classification of Diseases and Related Health Problems fra verdenssundhedsorganisationen World Health Organization, er en liste over anerkendte fysiske og mentale problemer.

Involves a specific impairment in arithmetical skills that is not solely explicable on the basis of general mental retardation or of inadequate schooling. The deficit concerns mastery of basic computational skills of addition, subtraction, multiplication, and division rather than of the more abstract mathematical skills involved in algebra, trigonometry, geometry, or calculus.

Developmental: acalculia, arithmetical disorder, Gerstmann’s syndrome.

Excludes: acalculia NOS (R48.8), arithmetical difficulties: associated with a reading or spelling disorder (F81.3), or due to inadequate teaching (Z55.8).

DSM-IV 315.1 – Mathematics Disorder

The Diagnostic and Statistical Manual of Mental Disorders, også kendt som DSM, er standarden indenfor kategorisering indenfor mentale problemer. Publiceret af American Psychiatric Association. DSM bruges af professionelle i USA og en del vestlige lande.

The Diagnostic and Statistical Manual of Mental Disorders, otherwise known as DSM, is the standard classification of mental disorders used by mental health professionals in the United States and some countries in the Western world. It is published by the American Psychiatric Association. This is the official listing of dyscalculia in the DSM-IV;

Students with a mathematics disorder have problems with their math skills. Their math skills are significantly below normal considering the student’s age, intelligence, and education.

As measured by a standardized test that is given individually, the person’s mathematical ability is substantially less than you would expect considering age, intelligence and education. This deficiency materially impedes academic achievement or daily living. If there is also a sensory defect, the mathematics deficiency is worse than you would expect with it.

Associated Features: Conduct disorder, Attention deficit disorder, Depression, Other Learning Disorders

Differential Diagnosis:
Some disorders have similar or even the same symptoms. The clinician, therefore, in his/her diagnostic attempt, has to differentiate against the following disorders which need to be ruled out to establish a precise diagnosis.

Cause:
Mathematics disorder is usually brought to the attention of the child’s parents when math instruction becomes a very important part of the classroom teaching. It is possible that some people have problems in math because of their genetic makeup. In contrast to some families whose members have great difficulty solving math problems, there are other families who tend to have members that consistently have a very high-level of math functioning.

Treatment:
Treatment for mathematics disorder includes individual tutoring, placement in special math classrooms with expert math teachers, and other educational aids that focus on math skills. Therefore, learning disorders are treated with specialized educational methods. In addition to special classroom instruction at school, students with learning disorders frequently benefit from individualized tutoring which focuses on their specific learning problem
