Which condition is linked to low levels of serotonin?

Low levels of serotonin are closely associated with clinical depression. Serotonin is a neurotransmitter that helps regulate mood, feelings of well-being, and happiness. When serotonin levels are insufficient, it can lead to symptoms associated with depression, such as persistent sadness, loss of interest in activities, and changes in sleep or appetite.

Research supports that individuals with clinical depression often exhibit decreased serotonin activity, and this relationship has led to the development of various antidepressants, such as selective serotonin reuptake inhibitors (SSRIs), which aim to increase serotonin levels in the brain to alleviate depressive symptoms. Understanding this connection is crucial for the effective management and treatment of depression in clinical settings.

In contrast, while other conditions listed may have complex neurobiological underpinnings, they do not have the same direct correlation with serotonin deficiency as clinical depression does.
