Another kind of impulsivity experienced by ADHD patients is a cognitive impulsivity.  Being neurologically impulsive is its symptom. People with this disorder tend to do a lot of guesswork and are very comfortable in solving many problems through guessing.

Within a short time-period a cognitively impulsive patient guesses a number of things and brings out an answer to all his problems.

When asked a question and given multiple choices as its answer, the patient tends to reach the answer through plain guesswork. If the questioner approves the answer then his guessing method is reinforced further.

The ways in which these patients solve their problems is very limited in number. They just take recourse to the trial and error method and try to approach the problem in that way. They are totally oblivious of the step-by step method that could have been deployed to solve it. This kind of a practice may put them forward as fast but in usual cases they become inaccurate in the long run and keep perpetuating their disorder, instead of endeavoring to control it.
