Cognition is the capacity of the brain to register and
decipher data dependent on information and experience. A
portion of the subjective aptitudes are processing, memory and
retention, logic and reasoning, attention and so forth. The
subjective abilities begin to grow directly from the hour of birth
of a person. There are situations where these advancements don't
happen at the opportune time or in a proficient manner, which
prompts scholarly disorders. The most commonly found
intellectual disorders in children are attention deficit
hyperactivity disorder (ADHD), epilepsy, encephalitis, autism
spectrum disorder (ASD) and speech disorders. There are
cognitive tasks and retraining intended for each sort of cognitive
issue. These are planned so as to improve the cognitive degrees of
the children who experience the ill effects of cognitive issues, for
an improvement in their everyday lives. This paper gives an
overview of some of the existing techniques for the improvement
of cognitive levels along with the techniques of EEG analysis.
The activities in the brain can be traced with the help of an
electroencephalogram (EEG). Cognitive levels can also be
studied with the help of EEG. The study that involves cognition
requires careful pre-processing, feature extraction and
appropriate analysis. The processed EEG information is
analysed utilizing various techniques which can extensively be
ordered into time domain, time frequency domain, frequency
domain, non-linear methods and artificial neural network
methods. Out of every one of these strategies, the frequency
domain techniques and time-frequency strategies are most
popularly used.
