Learn about trigeminal neuralgia, a painful neurological condition. Discover causes and symptoms, and how to access treatments such as Gamma Knife radiosurgery.
Each year, 7th October marks National Trigeminal Neuralgia Awareness Day, which offers a chance to focus on one of the most painful and misunderstood neurological conditions.
For those living with trigeminal neuralgia (TN), the simplest everyday activities, such as brushing teeth, smiling, or feeling a cool breeze, can trigger excruciating facial pain.
But what exactly is trigeminal neuralgia, and how can modern treatments like Gamma Knife radiosurgery help people reclaim their quality of life?
Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which is the main nerve responsible for sensation in the face. It’s often described as a sudden, sharp, electric shock-like pain that can affect one side of the face.
The pain can appear in short bursts lasting seconds or minutes, or in repeated attacks throughout the day. In severe cases, it can become constant and debilitating. Even gentle touch or mild temperature changes can trigger a painful episode.
While research is continually undergoing to understand the causes of trigeminal neuralgia, it is generally agreed that it involves the compression of the trigeminal nerve, often by a nearby blood vessel pressing on the nerve root. This pressure can disrupt normal nerve function and cause the intense pain signals associated with TN.
Less commonly, trigeminal neuralgia can result from other underlying conditions such as multiple sclerosis or, in rare cases, a tumour affecting the nerve pathway.
Diagnosis typically involves a detailed medical history and neurological examination. Imaging techniques like MRI scans are often used to rule out other causes of facial pain and to detect any nerve compression.
Because the symptoms can mimic other conditions such as dental problems, sinus issues, or migraines, many patients experience delays before receiving an accurate diagnosis.
Raising awareness through National Trigeminal Neuralgia Day helps improve recognition of these symptoms and encourages those affected to seek specialist assessment sooner.
There isn’t a one-size-fits-all treatment for TN, but there are several effective ways to manage symptoms and reduce pain. Most people begin with medication, particularly anticonvulsant drugs that help calm overactive nerves.
However, over time, some patients find that medications become less effective or cause side effects that impact daily life. For those cases, surgical or minimally invasive options may be considered. Among these, Gamma Knife radiosurgery is one of the most advanced and least invasive techniques available today.
Despite its name, Gamma Knife surgery is a highly precise form of stereotactic radiosurgery, using focused beams of gamma radiation to target the trigeminal nerve at its root. By delivering a concentrated dose of energy, Gamma Knife treatment disrupts the transmission of pain signals along the affected nerve, providing long-lasting relief for many patients.
The procedure is usually performed as a day case, allowing patients to return home the same day. It begins with the fitting of a lightweight frame or mask to help guide the treatment with pinpoint accuracy.
During the procedure, patients remain awake and can communicate with the care team throughout. The treatment itself is painless, and there is no need for stitches or recovery time in hospital. Most people resume normal activities within a day or two.
Gamma Knife has been used worldwide for over half a century, with an outstanding safety record. The risk of complications is very low compared to open surgery. Some patients may experience temporary numbness or tingling in the face, but serious side effects are uncommon.
Many people living with trigeminal neuralgia go years without a proper diagnosis or understanding of their condition.
Awareness days like 7th October play a vital role in ensuring people recognise the symptoms, access specialist advice, and learn about modern, less invasive treatments such as Gamma Knife radiosurgery.
By sharing experiences, supporting research, and promoting education, the TN community continues to make powerful strides toward better understanding and care.
