Other problems include impaired memory and ability to learn; difficulty thinking and problem solving; anxiety attacks or feelings of paranoia; impaired muscle coordination and judgment; increased susceptibility to infections; dangerous impairment of driving skills.
How do drugs affect behavior and mental processes?
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons.
How does alcohol affect behavior?
Drinking alcohol clearly has important effect on social behaviors, such as increasing aggression, self-disclosure, sexual adventuresomeness, and so on. Research has shown that these effects can stem from beliefs we hold about alcohol effects. Less is known about how alcohol itself affects these behaviors.
What is the influence of alcohol on your brain and Behaviour?
How Does Alcohol Affect the Brain? 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.
How does drugs affect the brain?
Drugs alter the way nerve cells normally send, receive, and process information. They do this by (1) imitating the brain’s natural chemical messengers, (2) by over-stimulating the “reward circuit” of the brain, (3) flooding the brain with excess chemicals, and (4) binding to receptors in the brain.
What drugs alter moods?

How do you know if you have brain damage from alcohol?
Difficulty walking, blurred vision, slurred speech, slowed reaction times, impaired memory: Clearly, alcohol affects the brain. Some of these impairments are detectable after only one or two drinks and quickly resolve when drinking stops.
How does alcohol affect memory?
Alcohol affects short-term memory by slowing down how nerves communicate with each other in a part of the brain called the hippocampus. The hippocampus plays a significant role in helping people form and maintain memories. When normal nerve activity slows down, short-term memory loss can occur.
Does alcohol change your body shape?
Studies show that those who engage in heavy drinking tend to consume diets higher in calories, sodium, and fats than those who do not drink. Excessive drinking could cause an individual to develop more of an “apple” body shape, where a higher level of body fat is distributed in the abdominal region.
Which part of brain is affected by drinking alcohol?
The Frontal Lobes: The frontal lobes of our brain are responsible for cognition, thought, memory, and judgment. By inhibiting its effects, alcohol impairs nearly every one of these functions. The hippocampus: The hippocampus forms and stores memory. Alcohol’s impact on the hippocampus leads to memory loss.
What happens in the brain with addiction?
In a person who becomes addicted, brain receptors become overwhelmed. The brain responds by producing less dopamine or eliminating dopamine receptors—an adaptation similar to turning the volume down on a loudspeaker when noise becomes too loud.
What causes drugs to be addictive?
Physical addiction appears to occur when repeated use of a drug changes the way your brain feels pleasure. The addicting drug causes physical changes to some nerve cells (neurons) in your brain. Neurons use chemicals called neurotransmitters to communicate. These changes can remain long after you stop using the drug.
