Problem gambling begins discreetly and privately. In most cases, an individual is unaware that they are developing an addiction to compulsive gambling right to the point where the condition starts interfering with day-to-day chores and responsibilities. Anxiety or depression is another concomitant symptom of burgeoning or pathological gambling addiction. Similar to other addictions, as in the case of substance addicts who overuse drugs or alcohol, problem gambling is driven by a chemical component in the brain.
