a. Provide a 3-5 sentence paraphrased summary of the assigned neurotransmitter purpose and function.
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.

Dopamine: Unveiling its Neurotransmission Role
Summary of Dopamine's Purpose and Function
Dopamine is a neurotransmitter that plays a crucial role in various brain functions, including motivation, reward-seeking behavior, movement control, and emotional regulation. It is involved in the brain's pleasure and reward pathways, influencing mood, attention, and decision-making processes.
Link to Psychiatric Diagnosis
Dopamine dysfunction has been linked to several psychiatric disorders, with schizophrenia being one of the most notable. In schizophrenia, there are abnormalities in dopamine transmission, leading to disturbances in perception, thought processes, and emotional responses.
Associated Symptoms and Neurotransmitter Imbalance
In schizophrenia, symptoms such as hallucinations, delusions, disorganized thinking, and social withdrawal are prevalent. These symptoms are often associated with an excess of dopamine activity in certain brain regions, contributing to the manifestation of psychotic symptoms.
Drug Class for Treatment and Mechanism of Action
The drug class commonly used to treat schizophrenia and target dopamine imbalance is antipsychotic medications. These medications can act as both dopamine receptor antagonists and partial agonists, depending on their specific mechanisms. By modulating dopamine activity in the brain, antipsychotics help alleviate psychotic symptoms, reduce the risk of relapse, and improve overall functioning in individuals with schizophrenia.
