central nervous system stimulant. A type of drug that increases the levels of certain chemicals in the brain and increases alertness, attention, energy, and physical activity. Central nervous system stimulants also raise blood pressure and increase heart rate and breathing rate.

What Are NDRIs? NDRIs block the transport of norepinephrine and dopamine back into the brain cells that released them. In turn, a greater number of active neurotransmitters remains available in the brain, which may over time lead to changes that help relieve the symptoms of depression.

Caffeine is defined as a drug because it stimulates the central nervous system, causing increased alertness. Caffeine gives most people a temporary energy boost and elevates mood. Caffeine is in tea, coffee, chocolate, many soft drinks, and pain relievers and other over-the-counter medications.

SNRIs work by blocking the reabsorption (or reuptake) of serotonin and norepinephrine back into the nerve cells that released them, which increases the levels of active neurotransmitters in the brain.

The immediate psychological effects of stimulant administration include a heightened sense of well-being, euphoria, excitement, heightened alertness, and increases in motor activity. Stimulants also reduce food intake, reduce sleep time, and may increase socialization activities.

How do adaptogens work? Adaptogens work at a molecular level by regulating a stable balance in the hypothalamic, pituitary, and adrenal glands. These are involved in the stress response. They work by “hacking” the stress response in the body.

The stimulant medications are effective as soon as they cross the blood-brain barrier, which takes 45 to 60 minutes.

They work by increasing the availability of the neurotransmitters norepinephrine and dopamine in your CNS connections. This speeds up your brain activity. Ritalin works sooner and reaches peak performance more quickly than Adderall does. However, Adderall stays active in your body longer than Ritalin does.

How do they work? Sedatives work by modifying certain nerve communications in your central nervous system (CNS) to your brain. In this case, they relax your body by slowing down brain activity. Specifically, sedatives make the neurotransmitter called gamma-aminobutyric acid ( GABA ) work overtime.

Adderall XR is a central nervous system stimulant most commonly used to treat ADHD. It's a Schedule II drug that works by altering certain natural chemicals in the brain. It can increase concentration, help people stay on task longer, and manage behavioral issues associated with ADHD.

Stimulants' Mechanisms of Action On a short-term basis, stimulants exert their effects by disrupting or modifying the normal communication that occurs among brain neurons and brain circuits. Cocaine and MA have both been shown to specifically disrupt the dopamine neurotransmitter system.

Stimulants are the most common type of medication prescribed for attention deficit disorder. They have the longest track record for treating ADHD and the most research to back up their effectiveness. The stimulant class of medication includes widely used drugs such as Ritalin, Adderall, and Dexedrine.

Gabapentin appears to work by altering electrical activity in the brain and influencing the activity of chemicals called neurotransmitters, which send messages between nerve cells. Brand names for gabapentin include Horizant, Gralise, and Neurontin. The medication is available in capsule, tablet, or liquid form.

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.

Neurotransmitters work locally and their actions are very fast. Both hormones and neurotransmitters influence our thoughts and motivations, as well as our ability to learn and concentrate. However, neurotransmitters' actions are short-lived while hormones act for longer periods of time.

What does the nervous system do? The nervous system along with the endocrine (hormonal) system works to control all activities within the human body. It does this by communicating messages between the brain and the body very quickly using nerve impulses (action potentials).
