b. Link the assigned neurotransmitter to a psychiatric diagnosis or diagnoses.
c. Discuss associated symptoms of the selected diagnosis or diagnoses. Determine if each symptom is related to an excess or deficiency in the neurotransmitter.

Serotonin: Unraveling its Neurotransmission Role
Summary of Serotonin's Purpose and Function
Serotonin is a neurotransmitter that regulates various physiological processes, including mood, sleep, appetite, and cognition. It plays a crucial role in promoting feelings of well-being, happiness, and emotional stability. Serotonin is also involved in controlling impulses and behaviors, as well as modulating pain perception.
Link to Psychiatric Diagnosis
Serotonin imbalance has been associated with mood disorders such as depression and anxiety. In conditions like depression, there may be alterations in serotonin levels, impacting mood regulation and emotional responses.
Associated Symptoms and Neurotransmitter Imbalance
In depression, symptoms like persistent sadness, loss of interest, changes in appetite or sleep patterns, and feelings of worthlessness are common. These symptoms are often related to a deficiency in serotonin levels, leading to disruptions in mood regulation and emotional well-being.
Drug Class for Treatment and Mechanism of Action
The drug class frequently used to treat depression and anxiety disorders associated with serotonin imbalance is selective serotonin reuptake inhibitors (SSRIs). SSRIs work by blocking the reuptake of serotonin in the brain, increasing its availability for neural signaling. By acting as reuptake inhibitors (agonists), SSRIs help improve mood, reduce anxiety symptoms, and enhance overall quality of life in individuals with these conditions.
