How Does Alcohol Change The Brain? A person's brain will start to feel the effects of alcohol as soon as it reaches the bloodstream. The liver plays an essential role in the detoxification process, and a healthy person can process alcohol quite quickly. However, excessive alcohol use causes rapid alterations in the brain because the liver cannot filter the alcohol quickly enough. Consistent heavy drinking is harmful to one's brain and liver. Excessive alcohol intake has been shown to have long-lasting impacts on the brain neurotransmitters, including reducing their efficiency and even mimicking them. Alcohol also damages brain cells and contracts brain tissue. Nutritional inadequacies can worsen brain damage in those with a history of heavy alcohol consumption. A person's overall health, the amount they drink, and the efficiency of their liver all play a role in the manifestations of alcohol-related brain injury. Dopamine and the Brain Chemical messengers called neurotransmitters can be found in the brain and are responsible for relaying impulses between neurons and distributing information throughout the body. One of these chemical messengers is dopamine, which is significantly affected by alcohol. Dopamine is a neurotransmitter that plays a role in our disposition because of its location in the brain's reward, pleasure, and motivational center. Elevated dopamine levels improve mood, boost motivation, and boost confidence. Low levels of dopamine are associated with feelings of depression and a lack of motivation. Dopamine levels naturally increase when we experience anything pleasurable, such as eating something good, exercising, spending time with friends, or receiving positive feedback on a work or school project. Having more dopamine in the brain makes us joyful and drives us to seek out more of the same rewarding experiences. Dopamine levels skyrocket in response to alcohol and other addictive substances, amplifying the reward from engaging in the behavior. The brain becomes accustomed to the elevated dopamine levels caused by chronic alcohol consumption, and its average dopamine production gradually decreases. When the brain's natural dopamine levels decline, it requires more alcohol to maintain the same level of artificial dopamine production. The development of tolerance is an indication of physical alcohol dependence. If someone quits drinking now, withdrawal symptoms will set in as the brain tries to rebalance itself after being constantly overstimulated. Alcohol, even in moderation, has been shown to enhance dopamine levels. According to one study, "this dopamine release may contribute to the rewarding effects of alcohol and may consequently play a role in increasing alcohol use," which was published in the journal Alcohol Health and Research World. What Parts of the Brain Does Alcohol Affect? The brain regulates conscious and unconscious processes, including thought, emotion, memory, movement, body temperature, sensation, organ function, and autonomic processes like breathing. All of these essential mental processes can be negatively impacted by alcohol. The Cerebral Cortex Our brain's Cerebral Cortex is where we do most of our critical thinking. This is the part of the brain responsible for evaluating new data and making choices. Alcohol lowers inhibitions and slows the processing of sensory data, among other negative effects. Regular alcohol consumption has been shown to cause irreversible changes in the brain's cortex. The Cerebellum The cerebellum controls movement, coordination, equilibrium, and balance. When we've had a few drinks, this part of the brain becomes impaired, and we become unsteady, stagger, and possibly fall. Also, it could make our hands tremble. The Hypothalamus and the Pituitary work When functioning correctly, the Hypothalamus and Pituitary gland connect the nervous system to the endocrine system. This section of the brain regulates critical hormonal processes by activating and blocking them to keep the body in check. Alcohol lowers inhibitions, throws off hormonal balance, and diminishes libido. The desire to engage in sexual activity may increase, although performance may suffer. The Medulla The Medulla regulates homeostatic processes like respiration, awareness, and core temperature. Alcohol impairs these fundamental processes, leading to drowsiness, slowed breathing, decreased body temperature, and maybe coma. Reduced ability to perform routine tasks poses serious health risks. The Hippocampal The Hippocampal formation is responsible for memory. Blackouts, memory loss, and a decrease in the ability to learn are all effects of alcohol on this region. The use of alcohol over a long period can have long-lasting effects on memory and increase the risk of developing dementia. The Central Nervous System The brain, spinal cord, and nerves comprise the Central Nervous System. Movement thought, and speech is slowed by alcohol because of the delayed transmission of signals to and from these regions. Long-Term Effects of Alcohol On The Brain Alcohol's many negative aftereffects can wear down the brain and other organs over time. It's possible that brain damage can be reversed if treated quickly enough. Some of alcohol's long-term effects on the brain are: Withdrawal symptoms Severe withdrawal symptoms have been linked to permanent brain cell damage. Hallucinations and convulsions are among the most concerning symptoms. Delerium Tremens (DTs) is the most severe form of alcohol withdrawal, affecting about 5% of people going through withdrawal. When neurotransmitters are damaged, it stifles communication between different brain parts and saps motivation. Brain shrinkage Gray matter, which houses cell bodies, and white matter, which regulates cell routes, both atrophy, leading to a smaller brain. In addition to numerous other studies, one published in the British Medical Journal in 2017 found that heavy alcohol use is associated with brain atrophy. Cognitive impairment Verbalization, mental processing, memory, learning, focus, and impulse control may all be negatively impacted by cognitive decline. Researchers have shown that alcohol is hazardous to the brain's problem-solving and impulse control parts. Dementia brought on by alcohol abuse may be caused by damage to this brain region. Wernicke-Korsakoff Syndrome According to Medical News Today, Wernicke-Korsakoff Syndrome is associated with severe thiamine shortage and alcohol-induced brain dysfunction. Wernicke can cause mental impairments like amnesia, disorientation, malnutrition, tremors, and balance problems. Memory loss, emotional instability, and impaired judgment are typical Korsakoff symptoms.
