What is ACALCULIA?

Acalculia is a term derived from Greek letter A, which means "no" and the Latin word caculare , which means "count". This sentence describes the acquired disorder affecting the ability of a person to perform basic mathematical functions. This disorder is usually caused by a stroke, tumor or trauma and is often associated with dementia. Dyscalculia is a similar disorder affecting mathematical ability, but differs from ACALCULIA because it is a developmental disorder that worsens the acquisition of mathematical skills in childhood. Patients will often have difficulty counting back and forth and lack basic numerical knowledge, for example how many weeks it is per year. When transcribing between numbers written in verbal form and numbers written in numerical form, there will often be significant problems between numbers written in verbal form and writing numbers with different levels of complexity and comparing the size of two numbers to determine which one is larger or smaller. The greatest difficulty can be observed PIdentifying mathematical operations and patients can be able to interpret simple mathematical features. Patients can even prove the inability to align the numbers in the columns.

This disorder is occasionally detected in its primary form, which is a basic defect in computational ability, but more often encounters a group of neurological symptoms that are referred to as Gerstmann's syndrome. In addition to Acalculie, the main symptoms of Gerstmann's inability to say verbally, called Agraphia; Problems identifying from the left, called left -right confusion; And the difficulty of distinguishing between the fingers of your own hand and/or the inability to reveal which Finger and the touch stimuli were applied in the absence of a visual allusion called Agnosia. Gerstmann's syndrome is usually associated with damage to the angular gyro of the left parietal lobe of the brain that may be the result of bleeding during a stroke orAbout traumatic head injury, viral encephalitis, tumor or exposure to toxins.

Acalculia prognosis varies depending on several factors, including the severity of the symptoms and the cause of the disorder. Treatment is often focused on the care of pathology that initiated a disorder such as stroke or viral infection; Acalculia and other symptoms associated with Gerstmann's syndrome may therefore decrease with the treatment procedure. Recovery related to primary acalculia is usually limited and instead focuses on mastering symptoms. The long -term rehabilitation program, which includes several activities that proceed from relatively simple, such as counting real objects, to more complex activities such as the use of patients, showed an overall improvement in mathematical skills of affected patients.
