By Mayo Clinic staffKleptomania is thought to be uncommon. However because many people with kleptomania never seek treatment or they're simply jailed after repeated thefts, many cases of kleptomania may never be diagnosed. It's thought that fewer than 5 percent of shoplifters have kleptomania. Kleptomania often begins during adolescence or in your 20s, but in rare cases it begins during very early childhood or late in life.
Although the cause of kleptomania isn't known, researchers continue to learn more about the factors that may increase the risk of developing kleptomania. These risk factors may include:
- Excessive life stressors, such as a major loss
- Head trauma or brain injuries
- Having blood relatives with kleptomania, mood disorders, addictions or obsessive-compulsive disorder
