Autonomic nervous system disorder due to substances is caused by the ingestion of certain drugs or chemicals. These substances can affect the autonomic nervous system, which is responsible for controlling unconscious body functions such as heart rate, blood pressure, digestion, respiration, and temperature regulation. Examples of substances that can cause autonomic nervous system disorders include alcohol, cocaine, and certain prescription medications.
Diagnosis of autonomic nervous system disorder due to substances is based on a patient’s medical history, physical examination, laboratory tests, and imaging studies. Symptoms of the disorder can vary depending on the substance ingested. Common symptoms include dizziness, sweating, lightheadedness, nausea, and blurred vision.
Differential diagnosis of autonomic nervous system disorder due to substances includes other possible causes of the disorder such as neurological diseases, endocrine disorders, and certain medications.
Treatment of autonomic nervous system disorder due to substances typically involves discontinuing the ingestion of the substance and providing supportive care. Other treatments may include medications to reduce symptoms and psychological counseling to address any underlying mental health issues.
The prognosis for autonomic nervous system disorder due to substances is generally good with treatment. However, the disorder can recur if the substance is ingested again, so it is important for patients to abstain from using the substance in the future.
