Sturge-Weber Syndrome: Characteristics, Consequences, and Identification
Sturge-Weber syndrome (SWS), a rare neurocutaneous disorder, is characterized by distinctive facial vascular birthmarks (port-wine stains) and abnormal blood vessel formation in the brain [1][3]. This condition affects approximately 1 in every 20,000-50,000 people in the United States [2].
**Key Characteristics and Diagnosis**
SWS is often diagnosed by a physician based on symptoms, particularly the presence of a port-wine stain, any incidence of glaucoma, and neurological symptoms such as convulsions. Imaging tests like X-rays of the skull, MRI with gadolinium, CT scans of the head, SPECT scans, and angiography can help identify neurological complications [1].
**Common Complications and Health Issues**
- **Neurological Problems** - Seizures (epilepsy) are among the most frequent neurological complications in SWS. They often occur early in life and typically affect the side of the body opposite to the port-wine stain [1][3]. - Hemiparesis, or muscle weakness, can develop on the affected side, often due to seizures or brain injury from lack of oxygen (ischemia) [1]. - Many children with SWS experience delays in learning, reasoning, and behaviour. The severity can range from mild to significant and may be related to the extent of brain involvement [1]. - There is an increased risk of migraine headaches in individuals with SWS [1].
- **Glaucoma and Ocular Complications** - Glaucoma, caused by increased intraocular pressure, is common, particularly if the port-wine stain involves the eye or eyelid. Glaucoma can develop in infancy or later in childhood and can lead to vision loss if not treated [1][3]. - Choroidal hemangioma, benign vascular tumors in the eye, can cause visual disturbances [1][5]. - Vision problems can result from glaucoma, choroidal hemangiomas, or other retinal complications [1][5].
- **Other Complications** - Abnormal blood vessel development is central to SWS and can involve the brain, eye, and skin. The absence of subcortical veins may lead to compensatory dilated deep medullary veins [2]. - Over time, affected individuals may develop brain atrophy and calcifications in the areas where abnormal blood vessels are present [2].
**Treatment and Management**
While there is no cure for SWS, people can take measures to treat the symptoms. Laser treatment can remove or lighten the birthmark, and doctors are now using a topical application known as sirolimus to prevent the capillaries from growing back [1]. Anticonvulsants can help prevent seizures. If these do not work, and the condition affects only one side of the brain, a surgeon may carry out a hemispherectomy [1].
Additional support includes physical therapy to strengthen muscles, regular full eye tests, individualized or specialized education for children experiencing developmental delays, and ongoing follow-up into adulthood [1].
**Summary Table: Key Complications**
| Complication | Description/Therapeutic Concern | |----------------------|--------------------------------------------| | Seizures/Epilepsy | Common, often severe, sometimes intractable| | Hemiparesis | Muscle weakness, often after seizures | | Developmental Delay | Cognitive, learning, and behavioural issues | | Glaucoma | Increased eye pressure, risk of vision loss| | Choroidal Hemangioma | Vascular tumor, visual disturbances | | Migraines | Frequent headaches | | Vascular Anomalies | Brain, eye, and skin vessel abnormalities |
Early diagnosis and multidisciplinary management are crucial to address these complications and optimize quality of life for individuals with SWS [1][3]. It is essential to remember that while SWS can present challenges, with proper care and support, many individuals with the condition can lead fulfilling lives.

- Although Sturge-Weber syndrome (SWS) is primarily associated with neurological disorders and skin conditions, individuals with SWS may also experience other medical conditions, such as epilepsy seizures or glaucoma.
- SWS is often characterized by the presence of port-wine stains and glaucoma, a condition that can lead to increased intraocular pressure and potential vision loss.
- Beyond neurological and ocular complications, people with SWS may face additional health challenges, including an increased risk of migraines, and vascular anomalies affecting the brain, eye, and skin.
- In the realm of skin care, laser treatments can help manage the distinctive port-wine stains associated with SWS, while health and wellness maintenance may involve regular eye exams and ongoing follow-ups, particularly for individuals with learning and developmental delays.
