dyscalculia
- Noun:
- A learning disability involving severe difficulty in understanding numbers and performing mathematical calculations: Dyscalculia is a specific cognitive disorder that impairs an individual's ability to comprehend arithmetic, learn mathematical facts, and perform accurate calculations.
- Noun:
- The student was diagnosed with dyscalculia, which explained his struggles with basic arithmetic.
- Dyscalculia can affect a person's ability to tell time or handle money.
- Teachers use specialized strategies to support learners with dyscalculia.
"Developmental dyscalculia": Refers to the condition when it is present from birth or early childhood, as opposed to being acquired later in life due to brain injury.
- Developmental dyscalculia is often identified when a child begins formal math education.
"Mathematical learning disability (MLD)": A broader term sometimes used synonymously with dyscalculia, though it may encompass a wider range of math-related difficulties.
- The research study focused on interventions for children with a mathematical learning disability (MLD), including dyscalculia.
Dyscalculic (adj): Pertaining to or affected by dyscalculia.
- Dyscalculic learners may benefit from visual aids and concrete examples.
Acalculia (n): The loss of the ability to perform simple arithmetic operations, typically due to acquired brain injury, in contrast to the developmental nature of dyscalculia.
- After the stroke, the patient exhibited acalculia alongside other cognitive deficits.
- Mathematics disorder: A clinical term often used in diagnostic manuals.
- Number blindness: An informal, descriptive term (less clinical).
- "Struggle with numeracy": A descriptive phrase for experiencing difficulty with mathematical concepts, which may or may not be due to dyscalculia.
- Many adults who struggle with numeracy may have undiagnosed dyscalculia.
This term refers specifically to a learning disability in the domain of mathematics. It is not simply a difficulty with math due to lack of instruction or effort. It is a neurological condition that affects how the brain processes numerical and spatial information. The reference context mentions an association with left temporo-parietal junction damage, which is one neurological correlate identified in research for acquired calculation disorders; developmental dyscalculia is more complex in its origins.
