SSRIs treat depression by increasing levels of serotonin in the brain. Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons.
How do antidepressants work in the brain?
It’s thought that SSRIs work by increasing serotonin levels in the brain. Serotonin is a neurotransmitter (a messenger chemical that carries signals between nerve cells in the brain). It’s thought to have a good influence on mood, emotion and sleep.
How does an antidepressant work explain with example?
In general, antidepressants work by inhibiting the reuptake of specific neurotransmitters, hence increasing their levels around the nerves within the brain, such as selective serotonin reuptake inhibitors (SSRIs), antidepressants that will affect serotonin levels in the brain.
How do antidepressants work?
That said, many researchers believe that the benefits of antidepressants stem from how they affect certain brain circuits and the chemicals (called neurotransmitters) that pass along signals from one nerve cell to another in the brain. These chemicals include serotonin, dopamine, and norepinephrine.
How do antidepressants work on the nervous system?
Antidepressants help correct chemical imbalances in your brain by affecting certain brain chemicals called neurotransmitters, which are responsible for sending messages between nerve cells. Neurotransmitters are responsible for different functions in the body.
Do antidepressants ruin your brain?
We know that antipsychotics shrink the brain in a dose-dependent manner (4) and benzodiazepines, antidepressants and ADHD drugs also seem to cause permanent brain damage (5).
Does your brain go back to normal after antidepressants?

Can antidepressants help the brain?
They may, literally, be changing your brain. Newer kinds of antidepressants are supposed to work by affecting brain chemistry. They are designed to put more chemical messengers — such as serotonin — in the gaps across which brain cells communicate. This is supposed to improve brain function.
