Difference Between Trigeminal Neuralgia and Atypical Trigeminal Neuralgia

Trigeminal neuralgia has two forms: trigeminal neuralgia (TN1) and atypical trigeminal neuralgia (TN2). While they both manifest with slightly different symptoms and frequency, if you’ve been diagnosed with either, you already know how debilitating they can be. Recognizing the difference between the two can help you better understand and decide on the course of treatment that’s right for you.

What Is Trigeminal Neuralgia?

Trigeminal neuralgia (TN1) is a malfunctioning of the trigeminal nerve. The trigeminal nerve is one of the five cranial nerves and provides much of the sensation to the cheeks, temples and jawline. When the trigeminal nerve is malfunctioning due to an injury or defect, it causes excruciating symptoms. Classical trigeminal neuralgia is typically caused by an impingement of the trigeminal nerve from a blood vessel.
