It is typically caused by a basilar skull fracture, which presents complications such as infection. It may be diagnosed using brain scans (prompted based on initial symptoms), and by testing to see if discharge from the nose is cerebrospinal fluid. Treatment may be conservative (as many cases resolve spontaneously), but usually involves ...
A headache diary can be useful in tracking when and where pain occurs, how severe it is, and how long the pain lasts. A record of coping strategies used may help distinguish between headache type; data on frequency, severity and duration of headache attacks are a necessary tool for initial and correct differential diagnosis in headache conditions.
Head injury may be associated with a neck injury. Bruises on the back or neck, neck pain, or pain radiating to the arms are signs of cervical spine injury and merit spinal immobilization via application of a cervical collar and possibly a longboard. If the neurological exam is normal this is reassuring.
The bleed can be very small without any significant effect on surrounding brain or large hemorrhage that exerts mass effect on adjacent brain. Follow up CT scan is recommended. Those with extension of bleed into the ventricular system, expansion of bleeding, or increasing cerebral oedema on CT scan gives poorer prognosis. CT angiography (CTA ...
The pain can ultimately become disabling unless the ambient pressure is reversed. The pressure difference causes the mucosal lining of the sinuses to become swollen and submucosal bleeding follows with further difficulties ventilating the sinus, especially if the orifices are involved. Ultimately fluid or blood will fill the space.
Nine in ten people with cerebral venous thrombosis have a headache; this tends to worsen over the period of several days, but may also develop suddenly (thunderclap headache). [3] The headache may be the only symptom. [5] Many have symptoms of stroke: inability to move one or more limbs, weakness on one side of the face or difficulty speaking ...
Cerebral edema is a severe complication of acute brain injuries, most notably ischemic stroke and traumatic brain injuries, and a significant cause of morbidity and mortality. [ 3 ] [ 10 ] [ 34 ] Cerebral edema is the cause of death in 5% of all patients with cerebral infarction and mortality after large ischemic strokes with cerebral edema is ...
