Neurology diagnoses and treats disorders of the nervous system, including the brain, spinal cord, and nerves, as well as thought and memory.

In the acute phase of neurotrauma, specific symptoms indicate that the brain is under lethal pressure. Cushing’s Triad is a late physiological response to high intracranial pressure, characterized by three signs: hypertension (high blood pressure), bradycardia (slow heart rate), and irregular respirations. This signals that the brainstem is being compressed.
Pupillary changes are a critical neurological sign. A “blown pupil” (fixed and dilated) typically indicates uncal herniation, where the temporal lobe is pushing against the oculomotor nerve. This is a surgical emergency. Motor posturing, such as Decorticate (arms flexed in) or Decerebrate (arms extended out), indicates deep damage to the brainstem pathways.
Concussion, or mild TBI, presents with a functional rather than structural disturbance. Symptoms reflect a “energy crisis” in the neurons. Physically, patients experience headaches, photophobia (light sensitivity), and phonophobia (sound sensitivity). Vestibular symptoms like dizziness and balance dysfunction are common due to the fragility of the inner ear connections.
Cognitively, “brain fog” is the hallmark. Processing speed slows down, making complex tasks exhausting. Amnesia regarding the event (retrograde or anterograde) is common. Unlike severe TBI, these symptoms are typically transient, but in a subset of patients, they persist as Post-Concussion Syndrome.
Focal deficits depend entirely on the location of the injury. A contusion in the left frontal lobe often causes expressive aphasia (difficulty speaking) and personality changes (disinhibition). Damage to the motor strip results in contralateral hemiparesis (weakness on the opposite side).
Occipital lobe trauma can cause cortical blindness, where the eyes work but the brain cannot see. Temporal lobe injuries often result in memory encoding failures and seizures. Neurologists map these deficits to specific brain regions to guide imaging and rehabilitation.
Traumatic neurology also encompasses the “dysautonomia” seen after brain injury. Paroxysmal Sympathetic Hyperactivity (PSH), or “storming,” is a condition seen in severe TBI where the body loses central control of the sympathetic nervous system. Patients experience cycles of rapid heart rate, high fever, sweating, and posturing without an external cause.
This autonomic storming increases metabolic demand on an already injured brain. It is often mistaken for infection or seizures. Proper identification is crucial because treating it requires suppressing the nervous system, whereas treating an infection requires antibiotics.
Certain factors predispose patients to worse neurological outcomes. The presence of the Apolipoprotein E4 (APOE4) allele—a genetic risk factor for Alzheimer’s—is associated with poorer recovery from TBI. Age is a significant factor; the elderly brain has less plasticity and is more prone to tearing bridging veins due to atrophy.
Anticoagulation status is a major medical risk. Patients on blood thinners (like Warfarin or Apixaban) who sustain even minor head trauma are at high risk for “delayed expansion” of intracranial hemorrhage. Reversal of these drugs is the first priority in trauma care.

It describes a pupil that is widely dilated and does not shrink when light is shined in it, usually indicating that a herniating brain is compressing the third cranial nerve.
“Storming” is a state where the body’s fight-or-flight system goes haywire because the brain can’t regulate it, causing fever, racing heart, and sweating.
Vomiting is a direct sign of increased intracranial pressure triggering the vomiting center in the brainstem; it is a red flag in head injury.
Yes, the “Second Impact Syndrome” phenomenon suggests that if the brain is injured again before it heals, the reaction can be catastrophic and fatal.
Posturing (stiffening of the arms and legs) is an involuntary reflex indicating that the connection between the brain and spinal cord has been disrupted.
