Neurotransmitter disorders are conditions that occur when the balance of neurotransmitters—chemical messengers in the brain—is disrupted. These disorders can affect mood, behavior, and cognitive functions. Common neurotransmitters include serotonin, dopamine, and norepinephrine, each playing a crucial role in regulating various bodily functions. Symptoms of neurotransmitter disorders can vary widely and may include anxiety, depression, or movement issues. Diagnosis often involves a combination of clinical evaluation and laboratory tests. Treatment options may include medications that target specific neurotransmitter systems, along with lifestyle changes and therapy to help manage symptoms effectively.
