I60.7

Clinical Causes: Ruptured berry (congenital) aneurysm Unexplained rupture of cerebral arteries Cerebral artery abnormalities High blood pressure leading to vessel weakening Genetic factors affecting blood vessel strength Certain blood vessel malformations

Key Symptoms: Sudden and severe headache, often described as the worst ever experienced Neck stiffness and neck pain Nausea and vomiting Sensitivity to light (photophobia) Blurred or double vision Loss of consciousness or confusion Sudden weakness or numbness, particularly on one side of the body Seizures in some cases

Diagnosis Path: Doctors typically use a combination of methods to diagnose this condition, including: - **Computed Tomography (CT) scan**: An immediate imaging test to detect bleeding - **Lumbar puncture (spinal tap)**: Analyzing cerebrospinal fluid for blood indicators if CT is inconclusive - **Cerebral angiography**: An imaging procedure that visualizes blood vessels to locate aneurysms or abnormalities - **Magnetic resonance imaging (MRI)**: To assess brain damage and exclude other causes Prompt diagnosis is crucial for effective treatment and better outcomes.

Treatment Protocols: Management of nontraumatic subarachnoid hemorrhage involves urgent medical intervention, potentially including: - **Surgical procedures**: Such as clipping or coiling to prevent further bleeding from aneurysms - **Medications**: To control blood pressure, prevent vasospasm, and manage pain - **Supportive care**: Including video monitoring, hydration, and addressing complications like hydrocephalus - **Rehabilitation**: Physical, speech, and occupational therapy to recover lost functions The approach depends on the extent of bleeding and overall patient health. Long-term follow-up is important to monitor for recurrence or additional vascular issues.
