Low levels of serotonin in the brain may cause depression, anxiety, and sleep trouble. Many doctors will prescribe a selective serotonin reuptake inhibitor (SSRI) to treat depression.

Why does my brain not produce serotonin?

Possible problems include low brain cell production of serotonin, a lack of receptor sites able to receive the serotonin that is made, inability of serotonin to reach the receptor sites, or a shortage in tryptophan, the chemical from which serotonin is made.

Can low serotonin affect memory?

Low Levels of Serotonin May Drive Memory Loss and Alzheimer’s. Lower levels of serotonin, the neurotransmitter that regulates happiness, sleep and appetite, may be a driving force behind the development of Alzheimer’s and memory loss, according to new research.

Can serotonin levels fluctuate?

Changes in diet and stress cause our serotonin levels to fluctuate naturally, so it’s important to understand how this might affect our everyday decision-making.” Where do we get Serotonin? The only way to get the raw material for serotonin (tryptophan) is through the diet.

Antidepressant medications called selective serotonin reuptake inhibitors (SSRIs) are often the first-line treatment of symptoms of serotonin deficiency such as depression and anxiety. SSRIs help your body use serotonin more efficiently.

Does serotonin affect aging?

Serotonin (5-HT) neuron and neurotransmitter loss in normal aging and neuropsychiatric diseases of late life may contribute to behavioral changes commonly observed in the elderly population. Extensive evidence implicates a deficit in serotonergic neurotransmission in the development of major depression.

Do serotonin levels decline with age?

In the serotonin system, the concentration of serotonin remains stable during nonpathological aging in both rodents and humans. The density of S-2 serotonin receptors declines 20-50\% with age in human frontal cortex and hippocampus, and by 30\% in mouse cortex.

What happens when serotonin levels are too low?

When serotonin levels are too low, this can weaken nerve signals. One of the most common symptoms of low serotonin is depression, but low serotonin levels can affect almost every system of the body, leading to a wide range of symptoms. Understanding Serotonin: What Does Serotonin Do?

Can a doctor check serotonin levels in the blood?

However, doctors usually only use this test to check for serotonin-producing tumors. Doctors don’t usually perform blood tests to assess serotonin levels because factors other than blood serotonin—such as metabolism, the behavior of serotonin receptors, and hormones—can affect the body’s ability to process and use serotonin.
