I68.2

Clinical Causes: Underlying autoimmune conditions such as lupus erythematosus or vasculitis syndromes Infections including bacterial, viral, or fungal infections that provoke vascular inflammation Other systemic diseases like rheumatoid arthritis or sarcoidosis that may involve cerebral arteries Trauma or injury leading to vascular damage and subsequent inflammation Reaction to certain medications or toxins that can cause vascular irritation

Key Symptoms: Headaches, which may be persistent or severe Neurological deficits such as weakness, numbness, or paralysis on one side of the body Visual disturbances including blurred vision or loss of sight Dizziness or balance problems Seizures or convulsions in some cases Cognitive changes such as confusion or difficulty concentrating Symptoms related to stroke, such as sudden weakness or speech difficulties

Diagnosis Path: Detailed medical history and physical examination focusing on neurological symptoms Neuroimaging studies such as MRI or CT scans to identify inflammation or damage in cerebral arteries Blood tests to detect signs of systemic inflammation or autoimmune activity Lumbar puncture (spinal tap) to analyze cerebrospinal fluid for signs of inflammation or infection Vascular imaging techniques like cerebral angiography to visualize arterial irregularities Biopsy of affected tissue, in some cases, to confirm inflammation and rule out other causes

Treatment Protocols: Immunosuppressive medications such as corticosteroids to reduce inflammation Treating the underlying disease contributing to arteritis, for example, managing autoimmune disorders Antiviral, antibacterial, or antifungal agents if infection is present Medications to prevent blood clots, such as antiplatelet or anticoagulant therapy Supportive treatments including physical therapy for neurological impairments Regular monitoring through imaging and clinical assessments to evaluate response to therapy
