Alert: cough medicine abuse will "change" people's brain

The data shows that there is an obvious trend of cough medicine abuse among the male teenagers in China A recent study found that cough medicine addicts have abnormalities in brain function and brain structure After eight years of innovative research, the research team of Guangdong Second People's Hospital and South China Normal University finally found that heroin and cough medicine can "change" people's brain It is known that the abnormal function and structure of these brain areas are closely related to addiction time, impulse characteristics and clinical manifestations The abnormalities were mainly concentrated in reward circuit, cognitive control and decision-making related brain areas Tian junzhang, the first adult of the project and the president of the second people's Hospital of Guangdong Province, introduced chronic drugs in China (http://www.chemdrug.com/) There are relatively few researches on addiction, especially for the research on Legal over-the-counter cough medicine, which is not fully understood in sociology and medicine, and the neurophysiological mechanism of addiction is not fully clear Therefore, there is a lack of imaging indicators for effective diagnosis, efficacy evaluation and prognosis judgment in clinical practice, which seriously limits the active treatment and rehabilitation of cough medicine addicts Tian junzhang led the team to select 30 heroin addicts aged 20-50, 80 chronic cough medicine addicts aged 20-50 and 30 heroin addicts treated with methadone The results showed that there were abnormalities in brain function and structure in heroin addicts and cough medicine addicts, mainly in reward circuit, cognitive control and decision-making related brain areas, such as orbital frontal cortex, cingulate cortex, thalamus, cuneiform lobe and so on This provides important image support for clinical guidance For patients with chronic cough medicine addiction, the study also found that the volume of prefrontal cortex gray matter related to inhibition and control decreased, and the damage of this brain area was related to the high impulsivity of patients Jiang Guihua, the second adult of the project and director of the imaging department of the second people's Hospital of Guangdong Province, said that people who are addicted to drugs and whose cerebral cortex becomes thinner due to drug abuse are more likely to be impulsive and gambling than normal people While drugs and drugs bring illusion and hallucination to patients, they may cause such terrible consequences as light birth due to such impulse.
