  • Traumatic Brain Injury

    Cochrane Database of Systematic Reviews Background Raised intracranial pressure (ICP) is an important complication of severe brain injury, and is associated with high mortality. Barbiturates are believed to reduce ICP by suppressing cerebral metabolism, thus reducing cerebral metabolic demands and cerebral blood[…][doi.org]

  • Migraine

    A migraine is a primary headache disorder characterized by recurrent headaches that are moderate to severe. Typically, the headaches affect one half of the head, are pulsating in nature, and last from two to 72 hours. Associated symptoms may include nausea, vomiting, and sensitivity to light, sound, or smell. The[…][en.wikipedia.org]

  • Epilepsy

    OBJECTIVE: To study seizure control and rates of foetal malformation in pregnancies of women with epilepsy treated with antiepileptic drug polytherapy. METHODS: The use of conventional statistical methods to analyse the Australian Pregnancy Register records of 1810 pregnancies in women with epilepsy, 508 treated[…][ncbi.nlm.nih.gov]

  • Intracerebral Hematoma

    Toxicological investigations were performed on an intracerebral hematoma, antemortem blood, and postmortem blood of an individual who was found unresponsive in his home. The hematoma was found to have ethanol at a concentration of 0.05% (w/v), and benzoylecgonine (a cocaine metabolite) was also confirmed at a[…][ncbi.nlm.nih.gov]

  • Subarachnoid Hemorrhage

    Subarachnoid hemorrhage (SAH) is a life-threatening condition that refers to bleeding into the subarachnoid space. Most cases are attributed to a ruptured aneurysm. Additionally, there are risk factors such as hypertension, atherosclerosis, smoking, and other conditions as well. Up to 50% of patients with SAH[…][symptoma.com]

  • Encephalopathy

    This EEG pattern is continuous and remains unchanged during both waking and sleeping states. Structural abnormalities can often be seen on cranial MRI.[orpha.net] The characteristic electroencephalogram (EEG) displays a suppression burst pattern (which appears with the onset of spasms) that is comprised of bursts of high amplitude spikes[orpha.net] […] and polyspikes that alternate with periods of low voltage basic rhythm (suppression).[orpha.net]

  • Encephalitis

    Encephalitis is inflammation of the brain. Severity is variable. Symptoms may include headache, fever, confusion, a stiff neck, and vomiting. Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing.Causes of encephalitis include viruses such as herpes simplex virus[…][en.wikipedia.org]
