In the brain, the serotonergic neurons located in the raphe nucleus are the unique resource of the neurotransmitter serotonin, which plays a pivotal role in the regulation of brain development and functions. Dysfunction of the serotonin system is present in many psychiatric disorders.

Serotonin. Serotonergic neurons originate in the dorsal and median raphe nucleii in the brainstem (Fig. 39.2). They project to the medulla and spinal cord, the cerebellum, the limbic system and striatum, and the cortex.

It is composed of 5-HT neurons located in three raphe nuclei, namely the raphe magnus (30 000 neurons), the raphe obscurus, and the raphe pallidus (1000 neurons), and in the ventral medullary reticular formation lying lateral to the raphe magnus and the pyramids.

The intestines and the brain produce serotonin. It is also present in blood platelets and plays a role in the central nervous system (CNS).

Causes of low serotonin However, some potential causes include : age-related health and brain changes. a poor diet. chronic stress.

Symptoms

• Agitation or restlessness.
• Confusion.
• Rapid heart rate and high blood pressure.
• Dilated pupils.

• Diarrhea.

B12 acts as a cofactor in synthesis of neurotransmitters such as serotonin and dopamine, thus B12 deficiency affects mood, emotions and sleeping and can lead to psychiatric disorders.

Vitamin D regulates TPH2 (in brain) and TPH1 (in gut), in serotonin synthesis pathways.

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed class of antidepressants. They work by raising your serotonin levels. These drugs include: Citalopram (Celexa)

The serotonin test measures the level of serotonin in the blood. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

Most cases of serotonin syndrome start within 24 hours after starting or increasing a serotonergic medication and the majority of those start within six hours.

Diet can also influence one’s mental health. Coffee increases your serotonin and dopamine levels … for as long as you take it. Once you stop drinking coffee, you will go into withdrawal. Your brain, used to the high levels of neurotransmitters, will act as if there is a deficiency.

Other anti-anxiety drugs include the benzodiazepines, such as as alprazolam (Xanax), diazepam (Valium), buspirone (Buspar), and lorazepam (Ativan).

Zoloft and Lexapro came in first for a combination of effectiveness and fewer side effects, followed by Prozac (fluoxetine), Paxil (paroxetine), Cymbalta, and Luvox among others. “We were surprised because we found a difference among antidepressants,” said Dr.
