- Similarly, “LRS” refers to “long-read sequencing,” which can read longer strands of DNA.

Anxiety Medication (SSRI)

You may be thinking of “SSRI," or “selective serotonin reuptake inhibitor”. SSRIs are commonly prescribed antidepressants. They ease depression by increasing the amount of serotonin in the brain. Serotonin is a chemical transmitter associated with positive feelings. SSRIs prevent serotonin from reentering neurons, making it more readily available.^{[10]
