Meningism

Meningism is a set of symptoms similar to those of meningitis, but not caused by meningitis. It is characterized by a triad of nuchal rigidity (neck stiffness), photophobia (intolerance to bright light), and headache. Meningism is often caused by irritation of the meninges, the membranes covering the brain and spinal cord.

Causes

Meningism can be caused by a variety of conditions, including:

• Subarachnoid hemorrhage: This is a type of stroke caused by bleeding in the space surrounding the brain.
• Brain tumor: A tumor in the brain can cause irritation of the meninges.
• Sinusitis: Inflammation of the sinuses can sometimes cause meningism.
• Migraine: Some people with migraines may experience symptoms of meningism.

Diagnosis

The diagnosis of meningism is usually made based on the patient's symptoms and medical history. A physical examination may reveal signs of meningism, such as nuchal rigidity. In some cases, further tests may be needed to determine the underlying cause of the symptoms.

Treatment

The treatment of meningism depends on the underlying cause. For example, if meningism is caused by a brain tumor, treatment may involve surgery, radiation therapy, or chemotherapy. If meningism is caused by sinusitis, treatment may involve antibiotics or other medications to reduce inflammation.
