The body will eventually develop dependence—the brain develops a chemical need for alcohol and cannot function normally without it.
What is it called when the brain develops a chemical need for alcohol?
Chemical dependency, the body’s physical and/or psychological addiction to a psychoactive (mind-altering) substance, such as narcotics, alcohol, or nicotine.
When the brain develops a chemical need for a drug and Cannot function normally without it?
Dependence - The condition that results when the brain develops a chemical need for a drug and cannot function normally without it. Overdose – The consequence of taking an excessive amount of a drug that leads to coma or death.
What is the chemical need for a drug or alcohol called?
Substance dependence is the medical term used to describe abuse of drugs or alcohol that continues even when significant problems related to their use have developed. Signs of dependence include: Tolerance to or need for increased amounts of the drug to get an effect.
What is the chemical need for alcohol?
The type of alcohol in the alcoholic drinks we drink is a chemical called ethanol.To make alcohol, you need to put grains, fruits or vegetables through a process called fermentation (when yeast or bacteria react with the sugars in food – the by-products are ethanol and carbon dioxide).
Does drinking change your brain chemistry?
Alcohol directly affects brain chemistry by altering levels of neurotransmitters — the chemical messengers that transmit the signals throughout the body that control thought processes, behavior and emotion. Alcohol affects both “excitatory” neurotransmitters and “inhibitory” neurotransmitters.
How does the brain adapt to alcohol?
As the brain grows used to alcohol, it compensates for alcohol’s slowing effects by increasing the activity of excitatory neurotransmitters, speeding up signal transmission. In this way, the brain attempts to restore itself to a normal state in the presence of alcohol.
What is a drug that slows the brain and body reactions?
Central Nervous System (CNS) depressants are medicines that include sedatives, tranquilizers, and hypnotics. These drugs can slow brain activity, making them useful for treating anxiety, panic, acute stress reactions, and sleep disorders.
What is the process of removing all alcohol from a person’s body called?
The liver is responsible for the elimination – through metabolism – of 95% of ingested alcohol from the body. The remainder of the alcohol is eliminated through excretion of alcohol in breath, urine, sweat, feces, milk and saliva.
What is the first brain function that is affected by alcohol in the body?
Alcohol has a profound effect on the complex structures of the brain. It blocks chemical signals between brain cells (called neurons), leading to the common immediate symptoms of intoxication, including impulsive behavior, slurred speech, poor memory, and slowed reflexes.
What is chemically dependent mean?
Chemical Dependency Defined
Chemical dependency is characterized by the repeated, uncontrollable use of alcohol and/or drugs in a way that threatens the individual’s physical and mental health and well-being as well as the physical safety and emotional well-being of those around him or her.
Does alcohol cause liver problems?
Alcohol-related liver disease (ARLD) is caused by damage to the liver from years of excessive drinking. Years of alcohol abuse can cause the liver to become inflamed and swollen. This damage can also cause scarring known as cirrhosis.
What is the improper or unsafe use of a drug?
Drug abuse is the intentional improper or unsafe use of a drug. Drugs used for recreational purposes are called drugs of abuse. Many drugs of abuse are illegal drugs.
Is hepatitis caused by alcohol?
What causes alcoholic hepatitis? Alcoholic hepatitis is caused by drinking too much alcohol. The liver breaks down alcohol. Over time, if you drink more alcohol than the liver can process, it can become seriously damaged.
What is the formula of ethanol?
Which area S of the brain are most affected by heavy drinking?
There is evidence that the frontal lobes are particularly vulnerable to alcoholism–related damage, and the brain changes in these areas are most prominent as alcoholics age (Oscar–Berman 2000; Pfefferbaum et al. 1997; Sullivan 2000) (see figure 2).
