Personal advice

If a partial performance disorder such as dyslexia and/or dyscalculia is suspected, standardized recording of school skills such as reading, writing, and/or arithmetic can be used instead.

Difficulties that arise in perception, learning and memory, attention, and executive functions (e.g. action planning, problem solving, flexibility, etc.) can be assessed professionally in a neuropsychological examination. The results provide the basis for an individual consultation, if necessary with recommendations for therapeutic measures.

If you wish, your child’s case can also be discussed with teachers and other specialists involved.
