The arithmetic difficulties may involve the reading or writing of numbers or arithmetic signs and misaligning or rotating digits or numbers, as well as inaccurately solving problems requiring calculation. Traumatic brain injury and cerebrovascular disease are the most common causes; however, demyelinating disease, neoplasm, and degenerative disease can also produce acalculia.
