The Monroe–Kellie doctrine states that the skull is a fixed and inelastic space and the accumulation of edema will compress vital brain tissue and blood vessels. [8] [38] Surgical treatment of cerebral edema in the context of cerebellar or cerebral infarction is typically done by removing part of the skull to allow expansion of the dura. [38]
Of those who have residual symptoms after PRES, this is attributable largely to hemorrhage. [1] [4] Non-resolution of MRI abnormalities has been linked with poorer outcomes. [4] The presence of brain hemorrhage and cytotoxic edema (brain edema with concomittant brain tissue damage) is also associated with a poor prognosis. [2]
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
As well as this, it is common to incur an elevated blood protein level and a high volume of lymph cells within the cerebrospinal fluid, resulting in swelling and enlargement of the brain. The most characteristic signs and symptoms experienced by patients with cerebellar degeneration include: [2] [4] muscle weakness; an uncoordinated, staggering ...
Same symptoms as ischemic stroke, but unconsciousness, headache, nausea, stiff neck, and seizures are more often in brain hemorrhages than ischemic strokes: Complications: Coma, persistent vegetative state, cardiac arrest (when bleeding is in the brain stem or is severe), death: Types
Leukoencephalopathy with Brainstem and Spinal Cord Involvement and Lactate Elevation (LBSL) is a rare, hereditary neurodegenerative disease.The disease is characterized by slowly progressive cerebellar ataxia and spasticity with dorsal column dysfunction (decreased position and vibration sense) in most individuals. [1]
An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema, can crush brain tissue, shift brain structures, contribute to hydrocephalus, cause brain herniation, and restrict blood supply to the brain. [13] It is a cause of reflex bradycardia. [14]
Second-impact syndrome (SIS) occurs when the brain swells rapidly, and catastrophically, after a person has a second concussion before symptoms from an earlier one have subsided. This second blow may occur minutes, days, or weeks after an initial concussion, [ 1 ] and even the mildest grade of concussion can lead to second impact syndrome. [ 2 ]
