Initially, DAI itself may not show significant bleeding or swelling on scans. You can think of the brain as a complex network of connections. Axons are the long, microscopic \u201cwires\u201d that allow different parts of the brain to communicate with each other. During a violent injury, these delicate wires can be stretched or torn. When this internal wiring is damaged, the brain can no longer send and receive signals normally. This is why DAI can cause deep or prolonged unconsciousness, even when a standard CT scan does not show large areas of bleeding or swelling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Key features of DAI:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Injury is <strong>diffuse<\/strong>, not focal<\/li>\n\n\n\n<li>Often <strong>not obvious on early CT scans<\/strong><\/li>\n\n\n\n<li>Strongly associated with <strong>coma and prolonged unconsciousness<\/strong><\/li>\n\n\n\n<li>Best detected with <strong>MRI<\/strong>, not CT<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The primary clinical problem is not bleeding itself, but <strong>disruption of brain connectivity<\/strong>, leading to impaired consciousness, cognition, and autonomic regulation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"489\" height=\"354\" src=\"https:\/\/neurohirurgija.in.rs\/wp-content\/uploads\/2025\/11\/Brain-anatomy-Lobes.jpg\" alt=\"Main parts of the brain: the four lobes (frontal, parietal, temporal, and occipital), the cerebellum, and the brainstem.\" class=\"wp-image-8272\" srcset=\"https:\/\/neurohirurgija.in.rs\/wp-content\/uploads\/2025\/11\/Brain-anatomy-Lobes.jpg 489w, https:\/\/neurohirurgija.in.rs\/wp-content\/uploads\/2025\/11\/Brain-anatomy-Lobes-300x217.jpg 300w, https:\/\/neurohirurgija.in.rs\/wp-content\/uploads\/2025\/11\/Brain-anatomy-Lobes-18x12.jpg 18w\" sizes=\"auto, (max-width: 489px) 100vw, 489px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Image: Main parts of the brain: the four lobes (frontal, parietal, temporal, and occipital), the cerebellum, and the brainstem.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 id=\"why-causes-coma\" class=\"wp-block-heading\">Why DAI Causes Prolonged Coma<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Families often ask:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cWhy isn\u2019t the patient waking up if the CT doesn\u2019t look so bad?\u201d<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">This is a classic DAI scenario.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In DAI:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Axonal injury disconnects cortical\u2013subcortical networks<\/li>\n\n\n\n<li>Brainstem and deep structures involved in arousal may be affected<\/li>\n\n\n\n<li>Consciousness can be severely impaired <strong>without large mass lesions<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As a result:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Coma may persist for days or weeks<\/li>\n\n\n\n<li>Neurological exam may not correlate with CT appearance<\/li>\n\n\n\n<li>Sedation can further obscure the true neurological state<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In everyday practice, we rarely see severe grades of DAI without other types of brain injuries that cause bleeding (brain contusions, hematoma) visible on a CT scan.

In these cases, <strong>ICP-directed neurocritical care becomes a central part of treatment<\/strong>, similar to other severe TBI patterns.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Brain swelling in DAI<\/strong> results from a combination of damaged nerve fibers (axonal disruption), a breakdown in the brain\u2019s protective filter (<strong>blood\u2013brain barrier<\/strong>), and intense inflammation. It is also worsened by <strong>secondary insults<\/strong>\u2014additional stresses on the brain such as low oxygen (<strong>hypoxia<\/strong>), low blood pressure (<strong>hypotension<\/strong>), fever, seizures, or infection. For this reason, <strong>ICP<\/strong> (brain pressure) <strong>may be normal at first but can rise later<\/strong>, often unpredictably.

Instead of forming one large bruise or blood clot, DAI damages the brain\u2019s internal communication pathways \u2014 the axons \u2014 which connect different brain regions. This is why DAI is often described as a \u201cwiring injury.\u201d It commonly occurs after traffic accidents, falls from height, assaults, or other severe head injuries. DAI can cause prolonged unconsciousness or coma even when the first CT scan does not show a large hematoma or obvious mass effect.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Why doesn\u2019t the CT scan look severe if the patient is in a coma?<\/h3><\/summary>\n    <div class=\"answer\">\n      In diffuse axonal injury, the most important damage is microscopic and affects deep brain connections rather than forming one large visible blood clot. CT scans are excellent for detecting epidural hematoma, subdural hematoma, brain contusions, skull fractures, swelling, and mass effect, but CT can miss many axonal injuries. This creates a confusing situation for families: the CT may look \u201cnot catastrophic,\u201d while the patient remains deeply unconscious. In that situation, DAI is one of the key explanations. MRI, neurological examination, sedation status, ICP trends, and the overall ICU course are needed to understand why coma persists despite limited CT findings.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">How is DAI different from a brain contusion?<\/h3><\/summary>\n    <div class=\"answer\">\n      DAI and brain contusion are different types of traumatic brain injury. A brain contusion is a focal bruise of brain tissue, often visible on CT as bleeding and swelling in one or more areas, commonly in the frontal or temporal lobes. Diffuse axonal injury is a deeper and more widespread injury of white-matter pathways, corpus callosum, and sometimes the brainstem. DAI may not be obvious on early CT and is often better detected on MRI. Both injuries can coexist. When a patient remains in coma even after visible contusions or hematomas are treated, associated DAI is often one of the most important explanations.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Can DAI be missed on early imaging?<\/h3><\/summary>\n    <div class=\"answer\">\n      Yes. Diffuse axonal injury can be missed on early imaging, especially on the first emergency CT scan. CT is usually performed first because it is fast and detects life-threatening bleeding, fractures, swelling, and mass effect. However, DAI often consists of microscopic axonal disruption and small deep lesions that may be invisible or underestimated on CT. MRI is more sensitive, especially with sequences that detect small hemorrhages and white-matter injury. DAI should be suspected when the level of coma or neurological impairment is more severe than expected from the CT findings. In that situation, MRI can help confirm the diagnosis and clarify severity.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Why is MRI important in suspected DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      MRI is important in suspected diffuse axonal injury because it can detect lesions that CT often misses. MRI may show small hemorrhagic or non-hemorrhagic injuries in the deep white matter, corpus callosum, basal ganglia, brainstem, or other structures involved in consciousness and communication between brain regions. The location and extent of these lesions help confirm the diagnosis and estimate severity. Brainstem and corpus callosum involvement usually suggest a more severe injury pattern. MRI does not predict outcome perfectly, but it helps explain why a patient remains unconscious when CT does not show a large compressive lesion.

Some patients begin to wake within days as sedation is reduced and swelling stabilizes. Others remain unconscious for weeks, especially when DAI involves the corpus callosum, brainstem, or is associated with swelling, hypoxia, seizures, infection, or other traumatic brain lesions. Delayed awakening is common in DAI and does not automatically mean irreversible brain damage. Prognosis depends on repeated neurological examinations, MRI findings, ICU complications, breathing and brainstem function, ICP control, and whether purposeful responses gradually appear over time.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Does deep sedation mean the patient is permanently unconscious?<\/h3><\/summary>\n    <div class=\"answer\">\n      No. Deep sedation does not mean that the patient is permanently unconscious. In severe DAI and other severe traumatic brain injuries, sedation is often necessary for mechanical ventilation, pain control, prevention of agitation, seizure control, and intracranial pressure management. A deeply sedated patient may not open the eyes, move purposefully, or follow commands even if some neurological recovery is possible. Doctors usually reduce sedation when it is safe to reassess the neurological examination. Families should understand that early non-awakening may reflect medications, swelling, metabolic factors, or ICU strategy, not only the permanent severity of the brain injury itself.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Can intracranial pressure (ICP) rise in DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      Yes. Intracranial pressure can rise in severe diffuse axonal injury, even though DAI is not a focal mass lesion like a hematoma. Severe DAI may be associated with diffuse brain swelling, impaired blood\u2013brain barrier function, inflammation, hydrocephalus, seizures, or systemic complications that worsen brain edema. ICP may be normal early and rise later, especially during the first days after injury. This is why close ICU monitoring is important. Elevated ICP can reduce blood flow to the brain and cause secondary ischemic injury. Treatment focuses on protecting the injured brain from further damage while waiting for axonal function to recover as much as possible.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">How is ICP monitored in severe DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      ICP in severe DAI may be monitored with an intracranial pressure probe or with an external ventricular drain (EVD), depending on the CT findings, ventricular size, hydrocephalus, bleeding pattern, and ICU resources. An ICP probe measures pressure continuously inside the skull. An EVD can measure pressure and also drain cerebrospinal fluid when hydrocephalus or pressure elevation is present. Continuous monitoring helps the ICU team decide when to escalate treatment, adjust sedation, use osmotherapy, change ventilation strategy, or consider decompressive surgery. The decision to place an ICP monitor or EVD is individualized and depends on the patient\u2019s neurological state and injury pattern.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">What treatments are used to control ICP in DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      ICP treatment in severe DAI is usually stepwise. Basic measures include head elevation, neutral neck position, adequate oxygenation, blood pressure support, fever control, seizure prevention, and avoidance of hypoxia or hypotension. Sedation and pain control reduce agitation, coughing, and pressure spikes. Osmotherapy with mannitol or hypertonic saline may be used when brain swelling raises ICP. Ventilation is carefully managed, and short-term controlled hyperventilation may be used only as a rescue measure in dangerous pressure crises. If ICP remains uncontrolled despite optimized ICU care, external ventricular drainage or decompressive craniectomy may be considered in selected patients with severe swelling.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Can surgery help in diffuse axonal injury?<\/h3><\/summary>\n    <div class=\"answer\">\n      Surgery cannot remove or repair diffuse axonal injury itself because DAI is a microscopic injury of widespread brain connections, not a single clot or bruise that can be evacuated. However, surgery may help in selected situations when DAI is accompanied by severe brain swelling, refractory intracranial pressure, hydrocephalus, or associated focal lesions such as subdural hematoma or brain contusions. Decompressive craniectomy may be used as a life-saving pressure-control procedure when medical treatment fails. The goal is not to cure DAI, but to prevent fatal secondary injury from sustained high ICP and to give the injured brain time to recover as much as possible.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Why is decompressive craniectomy often bilateral in DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      Decompressive craniectomy may be bilateral in DAI because the swelling is often diffuse or global rather than limited to one side of the brain. In a large unilateral subdural hematoma, one side may be the main source of pressure, so unilateral decompression may be appropriate. In severe DAI-related edema, both hemispheres can be swollen, and pressure may not be dominated by one focal mass lesion. In that situation, bifrontal or bilateral decompression may be considered to provide broader pressure relief. The decision depends on ICP trends, CT findings, brain swelling pattern, basal cistern compression, associated lesions, and the overall clinical context.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">What does Grade 1, 2, or 3 DAI mean?<\/h3><\/summary>\n    <div class=\"answer\">\n      DAI grading describes how deep and severe the axonal injury appears on imaging or pathology. Grade 1 usually involves axonal injury mainly in the cerebral hemispheres or white matter. Grade 2 includes involvement of the corpus callosum, the major connection between the two brain hemispheres. Grade 3 includes brainstem involvement and is generally considered the most severe form. Higher grades usually suggest a greater risk of prolonged coma and disability, but grading alone does not determine outcome. Age, oxygenation, blood pressure, ICP control, associated contusions or hematomas, ICU complications, seizures, and rehabilitation quality also strongly influence recovery.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Does severe DAI always mean a poor outcome?<\/h3><\/summary>\n    <div class=\"answer\">\n      Severe DAI does not always mean the same outcome for every patient. Brainstem involvement, prolonged coma, severe swelling, hypoxia, hypotension, seizures, and ICU complications are concerning factors, but recovery can vary widely. Some patients with severe DAI remain deeply disabled, while others gradually regain awareness, communication, and functional abilities over months. MRI grade is important, but it is not the whole prognosis. The clinical trajectory matters: brainstem reflexes, breathing, eye opening, purposeful movement, command following, ICP control, infection prevention, and rehabilitation response all contribute to the final outcome. Prognosis should therefore be updated over time, not fixed on day one.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">Are seizures common after diffuse axonal injury?<\/h3><\/summary>\n    <div class=\"answer\">\n      Seizures can occur after diffuse axonal injury, especially when DAI is part of a broader traumatic brain injury pattern that also includes cortical contusions, hematomas, subarachnoid hemorrhage, or penetrating trauma. Early seizures are important because they can increase oxygen demand, raise intracranial pressure, and worsen secondary brain injury. ICU teams may use seizure prevention medication in moderate or severe traumatic brain injury, depending on the injury pattern and local protocols. If unexplained movements, worsening consciousness, or autonomic instability occur, EEG may be needed to look for seizures. Long-term seizure risk depends on associated cortical injury, hemorrhage, and recovery course.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">What is autonomic dysfunction in DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      Autonomic dysfunction in DAI means instability of automatic body functions controlled by the brain, such as heart rate, blood pressure, temperature, sweating, breathing pattern, and stress responses. It can occur because diffuse injury disrupts deep brain networks and brainstem-related regulation. Families may see episodes of high heart rate, high blood pressure, fever, sweating, or unusual posturing. These episodes do not always mean that a new structural injury has occurred, but they can complicate ICU care and increase metabolic stress on the injured brain. Treatment focuses on identifying triggers, controlling fever and pain, preventing seizures, maintaining oxygenation, and reducing secondary injury.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">What ICU complications most affect prognosis in DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      ICU complications can strongly influence prognosis in DAI because the injured brain is vulnerable to secondary injury. The most important complications include low oxygen, low blood pressure, fever, seizures, pneumonia, sepsis, electrolyte imbalance, high intracranial pressure, hydrocephalus, blood clots, and metabolic instability. Even if the original axonal injury cannot be reversed, preventing these secondary insults can improve the chance of recovery. This is why ICU care is central in DAI treatment. Families often focus only on MRI grade, but day-to-day ICU stability, infection control, oxygenation, blood pressure, ICP trends, and seizure prevention can be just as important for outcome.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">What should families expect during the first 72 hours?<\/h3><\/summary>\n    <div class=\"answer\">\n      During the first 72 hours after severe DAI or suspected DAI, families should expect uncertainty. The ICU team usually focuses on stabilizing oxygenation, blood pressure, ventilation, sedation, temperature, seizures, and intracranial pressure. CT is used to exclude surgical emergencies, while MRI may be performed when the patient is stable enough and coma remains unexplained by CT. Sedation may prevent a reliable neurological examination early on. Lack of awakening during this period does not automatically define the final prognosis. The key is the trend: whether swelling stabilizes, ICP remains controlled, infections are avoided, and neurological responses begin to appear when sedation is safely reduced.\n    <\/div>\n  <\/details>\n\n  <details>\n    <summary style=\"cursor:pointer;list-style:none;\"><h3 style=\"display:inline;font-size:1.05em;font-weight:700;margin:0;color:#003366;\">When should families seek a second opinion for DAI?<\/h3><\/summary>\n    <div class=\"answer\">\n      Families often seek a second opinion for DAI when the patient remains unconscious and the CT scan does not seem to explain the severity, when MRI findings are difficult to understand, when doctors mention Grade 2 or Grade 3 DAI, when intracranial pressure rises, or when decompressive craniectomy or major ICU decisions are being discussed. A second opinion can also help when explanations are unclear or when family members need a realistic interpretation of prognosis.

Families can request a telehealth neurosurgery second opinion for diffuse axonal injury, including priority review in urgent situations. This can be especially useful when a loved one is in ICU, on a ventilator, deeply sedated, not waking as expected, or when MRI findings and prognosis are unclear. A focused review can help explain whether the clinical state fits DAI, whether CT or MRI findings suggest associated injuries, how ICP and sedation may affect the exam, and what families can realistically expect in the first days and weeks.\n      <a href=\"https:\/\/neurohirurgija.in.rs\/en\/second-opinion-in-neurosurgery-trusted-insight\/\" target=\"_blank\" rel=\"noopener\" style=\"color:#005c99; text-decoration:underline;\">\n        Learn more about our neurosurgery second opinion\n      <\/a>.\n    <\/div>\n  <\/details>\n\n<\/div>\n\n\n\n<h2 id=\"additional-information-tbi-dai\" style=\"margin-top:34px;\">Additional Information (External Resources)<\/h2>\n\n<ul style=\"line-height:1.6; padding-left:18px;\">\n  <li>\n    <a href=\"https:\/\/www.cdc.gov\/traumaticbraininjury\/index.html\" target=\"_blank\" rel=\"noopener\">\n      CDC (USA): Traumatic Brain Injury (TBI) \u2014 overview, symptoms, and basics\n    <\/a>\n  <\/li>\n\n  <li>\n    <a href=\"https:\/\/medlineplus.gov\/traumaticbraininjury.html\" target=\"_blank\" rel=\"noopener\">\n      MedlinePlus (NIH): Traumatic Brain Injury \u2014 patient-friendly medical information + links\n    <\/a>\n  <\/li>\n\n  <li>\n    <a href=\"https:\/\/www.nhs.uk\/conditions\/head-injury-and-concussion\/\" target=\"_blank\" rel=\"noopener\">\n      NHS (UK): Head injury and concussion \u2014 when to seek urgent care + recovery notes\n    <\/a>\n  <\/li>\n\n  <li>\n    <a href=\"https:\/\/flipbooks.leedsth.nhs.uk\/LN000946.pdf\" target=\"_blank\" rel=\"noopener\">\n      Leeds Teaching Hospitals NHS Trust (PDF): \u201cFollowing a head injury\u201d \u2014 includes a clear section on Diffuse Axonal Injury (DAI)\n    <\/a>\n  <\/li>\n<\/ul>\n\n\n\n<nav aria-label=\"Pages in this hub\" class=\"hub-mini\"\n     style=\"background:#f4faff;border:1px solid #cce5ff;border-radius:8px;\n            padding:9px 11px;margin:14px 0;font-size:13.5px;line-height:1.5;\">\n  <div style=\"font-weight:700;color:#005c99;margin:0 0 6px 0;font-size:14px;\">\n    Pages in this Hub\n  <\/div>\n\n  <ul style=\"list-style:none;margin:0;padding:0;display:flex;flex-wrap:wrap;gap:8px 18px;\">\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/traumatic-brain-injuries-diagnosis-treatment-prognosis\/\">Traumatic Brain Injury (TBI) \u2014 Hub<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/concussion\/\">Concussion<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/epidural-hematoma-treatment-icu-prognosis\/\">Epidural hematoma (EDH)<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/subdural-hematoma-treatment-icu-prognosis\/\">Subdural hematoma (SDH)<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/chronic-subdural-hematoma-symptoms-and-treatment\/\">Chronic subdural hematoma<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/brain-contusions-treatment-icu-prognosis\/\">Brain contusions<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/diffuse-axonal-injury-dai-icu-care-diagnosis-prognosis\/\">Diffuse axonal injury (DAI)<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/tsah-traumatic-subarachnoid-hemorrhage\/\">Traumatic SAH<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/skull-fractures-clear-practical-explanation\/\">Skull fractures<\/a><\/li>\n    <li><a href=\"https:\/\/neurohirurgija.in.rs\/en\/gunshot-and-shrapnel-head-injuries\/\">Gunshot &amp; shrapnel injuries<\/a><\/li>\n  <\/ul>\n<\/nav>\n\n<script>\n(function(){\n  var here = location.pathname.replace(\/\\\/+$\/,'') + '\/';\n  document.querySelectorAll('nav.hub-mini a').forEach(function(a){\n    var ap = a.pathname.replace(\/\\\/+$\/,'') + '\/';\n    if (ap === here){\n      var span = document.createElement('span');\n      span.textContent = a.textContent;\n      span.setAttribute('aria-current','page');\n      span.style.fontWeight = '700';\n      span.style.color = '#005c99';\n      span.style.textDecoration = 'none';\n      a.replaceWith(span);\n    }\n  });\n})();\n<\/script>\n","protected":false},"excerpt":{"rendered":"<p>Author: Dr. Zeljko Kojadinovic, MD, PhD \u2014 Neurosurgeon and Pain Management Specialist Specialized Experience: 30 years of clinical expertise in neurosurgery and neurocritical care.
