Alcohol and drug abuse can cause devastating effects on the brain and body. It can also make mental illnesses worse. People who drink or abuse drugs often experience anxiety, depression, panic, and mood swings. When drinking and using drugs, there are several ways that the brain changes, including the size and structure of the brain. Browse the Best info about the Brain and Body.
The brain consists of billions of neurons. These neurons convert electrical signals into chemical signals. Some of these signals lead to the release of neuromodulators. Other chemicals like dopamine and serotonin help the brain control emotions. Drugs affect the brain by reducing the number of receptors for these chemicals. They also reduce the brain’s ability to enjoy natural rewards, such as pleasure.
Drugs can also kill white brain cells, which can dramatically affect how the brain functions. Specifically, drugs can damage the prefrontal cortex, which is necessary for impulse control and higher cognitive functions.
Alcohol and drugs can affect the brain by changing its brain’s structure, decreasing the number of gray cells, and rerouting communication pathways. This can cause permanent changes in how the brain works, which may persist even after stopping drug use.
Three primary areas of the brain are affected by drugs: the prefrontal cortex, the basal ganglia, and the cerebral cortex. Each of these regions controls a different function, such as decision-making, learning, and impulse control. Therefore, if these brain regions are affected by drug abuse, the individual’s ability to respond to temptations and avoid dangerous behaviors becomes compromised.
The brain’s frontal lobe regulates decision-making, choosing, and knowing right from wrong. An impaired amygdala, which controls the amygdala, can contribute to emotional problems, such as panic, extreme mood swings, and worry. Without a functioning amygdala, people are at increased risk of falling victim to crime.
Many drugs have addictive qualities, so long-term abuse of these substances can create a psychological dependency on the sense. To overcome addiction, the individual must be able to replace alcohol or other drugs with healthier alternatives. Relapse is expected after the end of alcohol or drug use.
Drugs can affect the brain in several ways, including reducing neurotransmitters and the number of receptors for these chemicals. Ultimately, substance use disorders are characterized by reduced impulse control, decreased motivation, and reduced ability to feel pleasure from naturally rewarding activities.
A person dependent on a substance, such as alcohol or a drug, may experience withdrawal symptoms, such as heart palpitations, insomnia, anxiety, and seizures. Addiction treatment therapies can help decrease these symptoms and improve the patient’s mental health.
If a substance-dependent person is in danger of alcohol or drug abuse, it is essential to seek help as soon as possible. Depending on the severity of the addiction, a short-term treatment can help to restore cognitive function, while a long-term treatment can reroute communication pathways and reverse physical damage.
