Debilitating Facial Pain May Be Trigeminal Neuralgia

All pain can be frightening, but when patients describe sharp, electric-type pain in their face, the cause may be Trigeminal Neuralgia, a treatable pain syndrome manifesting as unilateral facial pain that can be severe in intensity. The pain occurs in one or more distributions of the trigeminal nerve. The pain usually lasts for several seconds to several minutes followed by periods of being pain free. Trigeminal neuralgia pain can be triggered by sensory stimuli to the face including talking, brushing teeth, eating, and touching the face. In some cases, there is no trigger. The annual incidence of trigeminal neuralgia is approximately 4 in 100,000. The initial workup for trigeminal neuralgia may include an MRI of the brain to rule out brain tumor or MS plaques.

In many cases, trigeminal neuralgia is caused by compression of the facial nerve most commonly by the superior cerebellar artery or the anterior inferior cerebellar artery, although trigeminal neuralgia can be due to compression by a persistent permanent trigeminal artery or odioectatic basilar artery. Other causes of Trigeminal Neuralgia can include demyelinating disease (such as multiple sclerosis) and tumor. In some cases, the cause of Trigeminal Neuralgia is  ...

Carotid Stenosis: What you need to know

Carotid stenosis is a build of up plaque in the large arteries that supply the brain with blood. This buildup of plaque increases the risk of transient ischemic attack (TIA) and stroke. Risk factors for carotid artery stenosis include hypertension, hyperlipidemia, obesity, and tobacco use. Symptoms of carotid artery stenosis include facial droop, weakness or numbness on one side of the face and body, slurred speech, garbled speech, gait instability, dizziness, and visual disturbances including blurred vision, loss of vision and double vision.

Carotid artery stenosis can be diagnosed with several diagnostic studies including carotid ultrasound, MR angiography (MRA), CT angiography (CTA), and cerebral angiogram.

Treatment options for carotid artery stenosis vary depending upon the severity of stenosis, history of TIA or stroke, and...
