Also known as pathological gambling, it is an impulse control disorder. A compulsive gambler often finds it hard to refrain from activities including betting and gambling despite the negative consequences it has upon their personal relationships. A compulsive gambler is classified as an individual who will continue to engage in the activity even if all odds are against him (he is aware). This is simply because he cannot afford to lose and is always convincing himself that he will ultimately win even if it isn’t most likely so.
