Nicotine Addiction, Alcohol Use Disorder and Bipolar Disorder

Abstract

Bipolar affective disorder has a wide range of effects on human health and is extremely harmful, and the mortality rate of patients continues to grow. Meanwhile, most people, especially those with mental illness, tend to numb themselves by smoking and drinking. Unfortunately, tobacco and alcohol abuse are also extremely harmful to human health, moreover, the cost of living will be increased due to addiction of these things. At the same time, the unconscious mind after using alcohol and tobacco has also brought great uneasiness to society, thus leading to increased burden on individuals and society. This review discusses the genetics, comorbidity, and treatment of nicotine dependence, alcohol use disorder, and bipolar disorder, and finds that the severity of bipolar disorder patients is positively correlated with the severity of alcohol use disorder and nicotine dependence. Both patients with bipolar disorder and alcohol use disorder exhibit mutations in the BDNF gene, and an age peak in bipolar disorder coincides with a peak in nicotine dependence. In the end, it is believed that the interaction between comorbidities may become a breakthrough in the diagnosis or treatment of bipolar disorder in the future, and the easy-to-observe alcohol and nicotine intake can be used to assist in judging the current state of patients.
