Having particular difficulty mentally estimating the measurement of an object or distance (e.g., whether something is 10 or 20 feet (3 or 6 meters) away).
Often unable to grasp and remember mathematical concepts, rules, formulae, and sequences
Inability to concentrate on mentally intensive tasks
Low latent inhibition, i.e. over-sensitivity to noise, smell, light and the inability to tune out, filtering unwanted information or impressions. Might have a well-developed sense of imagination due to this (possibly as cognitive compensation to mathematical–numeric deficits)
Mistaken recollection of names. Poor name/face retrieval. May substitute names beginning with same letter
Just like Dyslexia, Dyscalculia is regarded as a specific learning difficulty. Dyscalculia has been associated with lesions to brain areas such as the Brodmann area 40 and angular gyrus at the junction between the temporal and parietal lobes of the cerebral cortex.
Neurofeedback can help children and adults with dyscalculia by training areas of the brain that are implicated as in this learning difficulty.
