Cognitive Assessment
The term cognitive training (also called brain training or neurobics) reflects a hypothesis that cognitive abilities can be maintained or improved by exercising the brain, in an analogy to the way physical fitness is improved by exercising the body.

What is MoCA ?
Montreal Cognitive Assessment
(MoCA)was designed as a rapid screening instrument for mild cognitive dysfunction. It assesses different cognitive domains:
- attention and concentration
- executive functions
- memory,language,visuoconstructional skills
- conceptual thinking
- calculations and orientation.
Time to administer the MoCA is approximately 10 minutes. The total possible score is 30 points; a score of 26 or above is considered normal.
What is TMT ?
Trail Making Test
The Trail Making Test is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. The test can provide information about visual search speed, scanning, speed of processing, mental flexibility, as well as executive functioning.It is sensitive to detecting cognitive impairment associated with dementia, for example, Alzheimer's disease.
The test is used to examine executive functioning and cognitive processing speed.
What is N-Back Test ?
N-Back Test
The n-back task is a continuous performance task that is commonly used as an assessment in cognitive neuroscience to measure a part of working memory and working memory capacity. The n-back was introduced by Wayne Kirchner in 1958.
To clarify, the visual n-back test is similar to the classic memory game of "Concentration". However, instead of different items that are in a fixed location on the game board, there is only one item, that appears in different positions on the game board during each turn. "1-N" means that you have to remember the position of the item, one turn back. "2-N" means that you have to remember the position of the item two turns back, and so on.
Performance on the n-back task seems to be more closely correlated with performance on measures of fluid intelligence than it is with performance on other measures of working memory.
