Mental health professionals believe there are two types of alcoholics, types 1 and 2.
|TYPE 1||TYPE 2|
|Genetics||Less Dependent||Stronger Genetic Basis|
|Onset||Tend to start drinking heavily in response to setbacks, losses (job loss), or other outside circumstances||Victims usually become heavy drinkers before they age of 25. They drink regardless of what 's happening in their lives and often have a history of fights and arrests.|
|Susceptibility||Equally men and women||Overwhelmingly men, yet few incidents of women|
|Severity||Less Severe||More Severe|
|Personality Traits||Tend to feel anxious, shy, pessimistic, sentimental, emotionally dependent, rigid, reflective, and slow to anger.||Tend to be impulsive, aggressive risk takers, curious, quick-tempered, optimistic, and excitable. They usually do not experience guilt, fear, or loss of control over their drinking.|
|Dependence||Drinking alcohol helps reduce Type 1 's anxiety level. But since drinking acts as a positive reinforcer, alcohol dependence develops rather quickly.||Type 2 alcoholics usually abuse drugs too.|
