Frequently Asked Questions
Acalculia is an acquired disorder, usually from brain injury or illness in a person who previously had normal calculation skills. Dyscalculia is a developmental learning disability present from childhood.
It is possible but rare. It is most commonly found alongside other neurological conditions like Gerstmann's syndrome, aphasia, or visuospatial disorders.
There is no direct cure, but cognitive rehabilitation and compensatory strategies can sometimes help patients manage the impairment to a degree, depending on the cause and extent of the brain damage.
It is diagnosed by specialists such as neurologists, neuropsychologists, or clinical psychologists through specific cognitive and arithmetic tests.
