The treatment of cerebral edema depends on the cause and includes monitoring of the person's airway and intracranial pressure, proper positioning, controlled hyperventilation, medications, fluid management, steroids. [3] [7] [8] Extensive cerebral edema can also be treated surgically with a decompressive craniectomy. [7]
Lateral temporal lobe seizures arising from the temporal-parietal lobe junction may cause complex visual hallucinations. [2] In comparison to medial temporal lobe seizures, lateral temporal lobe seizures are briefer duration seizures, occur with earlier loss of awareness, and are more likely become a focal to bilateral tonic-clonic seizure.

The contusion may cause swelling of the surrounding brain tissue, which may be irritated by toxins released in the contusion. [3] The swelling is worst at around four to six days after the injury. [3] Extensive contusion associated with subdural hematoma is called burst lobe. [5]
Symptoms will vary according to where the seizure occurs. When seizures occur in the frontal lobe, the patient may experience a wave-like sensation in the head. When seizures occur in the temporal lobe, a feeling of déjà vu may be experienced. When seizures are localized to the parietal lobe, a numbness or tingling may occur.
Limbic encephalitis is a rare condition with no randomised-controlled trials to guide treatment. Treatments that have been tried include intravenous immunoglobulin, plasmapheresis, corticosteroids, cyclophosphamide and rituximab. [1] If an associated tumour is found, then recovery is not possible until the tumour is removed.
Treatment is usually supportive in nature while also providing antiviral drug therapy. The primary exception to this is herpes simplex encephalitis, which is treatable with acyclovir . Prognosis is good for most individuals who are infected by an encephalitic virus but is poor among those who develop severe symptoms, including viral encephalitis.
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
Earlier treatment (within 48 hours of symptom onset) improves the chances of a good recovery. Rarely, treated individuals can have relapse of infection weeks to months later. There is evidence that aberrant inflammation triggered by herpes simplex can result in granulomatous inflammation in the brain, which responds to steroids. [ 16 ]
