Research shows that positive emotions like interest, joy, delight, and contentment increase flourishing in life. They broaden our momentary thought-action repertoires and build durable personal resources—physical, intellectual, and social.
Modafinil enhances learning, memory, and something called “fluid intelligence” in healthy people. It also helps people overcome insomnia and sleep apnea.
How Modafinil Affects Emotions
Buy Modafinil Australia is often used as a performance-enhancing drug by entrepreneurs and millennials seeking to improve their focus before important meetings or long work hours. While it has fewer side effects than some stimulants, its use can still have serious health implications. Modafinil increases levels of the chemicals and neurotransmitters that are associated with wakefulness, causing feelings of alertness, increased energy, and enhanced perception. In addition, it can affect mood and lead to feelings of depression, anxiety, and irritability.
This double-blind, placebo-controlled study examined the effects of modafinil on the neural circuitry that processes emotion and cognition. Healthy participants were administered modafinil or a placebo and underwent BOLD fMRI while performing two emotional information-processing tasks and a prefrontal-dependent cognitive task. The data showed that modafinil enhanced decoding accuracy for angry faces, but did not change recognition accuracy for other emotions or happy faces. It also caused more misclassification of angry faces as happy (main effect of the drug: F 3,63 = 7.38 p 0.001).
While the researchers did not examine how modafinil affected hormones or brain structures that regulate sleep, previous studies have shown that it acts as a wakefulness agent. In addition, it has been shown to decrease negative symptoms in people with schizophrenia when used as a supplement to psychostimulants. It is important to note that modafinil can cause dangerous or even life-threatening side effects if taken in high doses or for prolonged periods.
How Modafinil Affects the Brain
Modafinil has been shown to enhance activity in the brain areas that manage skills like memory, reasoning, and problem-solving. The drug is also known to increase blood flow in the brain, which may contribute to its stimulant effects. However, it’s important to note that long-term use can cause side effects such as nausea and headaches.
One study found that modafinil significantly improved arithmetic performance on the Pauli Test and 2-back WM and VAC tasks in medication-free narcolepsy patients. It did not, however, have significant effects on behavioral mood measures or cognitive performance in healthy controls. This could be because the study used a very low dose of modafinil (100 mg per day) in a small sample of carefully screened participants, and it did not assess dose-response effects.
In addition, BOLD fMRI revealed that Modalert 200 mg reduced amygdala reactivity to fearful face images and enhanced performance on the cognitive conflict task. Exploratory analyses showed that modafinil increased the correlation between right amygdala reactivity and task accuracy during cognitive conflict processing, but not during emotional conflict processing. The inferior frontal gyrus, which communicates with the dorsomedial prefrontal cortex, was also activated during cognitive conflict processing under modafinil.
The authors suggest that these findings may be related to a reduction in anxiety and fatigue on modafinil, as well as an enhancement of attention processes in the brain. Moreover, they found that the improvement in executive functions seen on modafinil may be mediated by the dorsomedial prefrontal cortex and its functional interaction with the amygdala.
How Modafinil Affects the Body
Modafinil is a wake-promoting medication that is prescribed to treat sleep disorders such as narcolepsy and shift work disorder. It is a powerful wake-promoting drug that can improve mood and cognition in people with narcolepsy, obstructive sleep apnea, and depression.
It increases dopamine and norepinephrine in the brain by blocking the reuptake of these chemicals. It is also believed to increase levels of the neurotransmitter serotonin. It is a potent stimulant that can cause agitation, paranoia, and anxiety in some people. You may need to decrease your dose or stop taking it.
Do not take modafinil if you have a history of mental health issues including psychosis, depression, or mania. It can also increase your heart rate and blood pressure. You should avoid consuming alcohol and smoking while taking modafinil. It can affect the effectiveness of hormonal birth control such as pills, injections, vaginal rings, and IUDs. It can also cause a serious skin reaction called Stevens-Johnson Syndrome.
You should not drive or operate machinery while taking modafinil because it can impair your thinking and judgment. It is a Schedule IV controlled substance in the United States and can be addictive. You should report any severe side effects to your doctor including chest pain, breathing difficulties, or a rash that spreads from the scalp to the rest of your body.
How Modafinil Affects the Mind
Modafinil, sold in the UK as Provigil, is a powerful wakefulness drug prescribed for the sleep disorder narcolepsy. However, it is increasingly being used without prescription by healthy people who want to stay awake for longer. A poll of Nature Journal readers suggested that one in five have done this. It’s also being taken by people studying for exams, to improve their focus and concentration. However scientists have never studied the effects of long-term use, and the drug’s safety in healthy people is not known.
In the short term, studies have found that modafinil has few effects on mood, and even when it increases creativity in some tasks, these effects are small and inconsistent. In other tests, it improves decision-making and planning. However, it doesn’t seem to improve working memory or flexibility of thinking.
Several studies have shown that modafinil decreases fatigue, and in a few cases, it improves depression. But in most trials, it makes no difference to mood or causes minor side effects such as insomnia, nausea, and stomach ache, which are also reported by people taking placebos.
A few studies have found that modafinil blocks dopamine transporters and increases dopamine in the nucleus accumbens, which helps to explain why it can increase motivation and mood in some people. It also interacts with the trace amine system, which may affect the reward system and lead to addiction. In addition, it can interact with some antidepressants and may cause liver or kidney problems in people with pre-existing conditions. Read More Blog…
