Electroencephalogram (EEG)
Electroencephalography (EEG) is the recording of electrical activity along the scalp, which corresponds to the voltage fluctuations caused by ionic current flows within brain neurons.

Cerebral venous thrombosis (CVT) refers to thrombus formation in either the deep or superficial venous drainage systems of the brain. The etiology is multifactorial and the presentation is variable, with diagnosis requiring a high index of suspicion
Bispectral Index (BIS) Monitoring: BIS monitor was developed by Aspect Medical Systems; BIS = bispectral index; other 'depth of anaesthesia' monitors exist (e.g. Entropy)
Neurological Toxicity of Chemotherapy: Encephalopathy; Cerebellar Syndrome; Myelopathy; Peripheral Neuropathy; Stroke and Venous Thrombosis; SIADH
Acute non-traumatic weakness may occur as a result of a wide variety of underlying etiologies, many of which are life-threatening
Anti-NMDA Receptor Encephalitis is an under-recognised progressive neurological disorder caused by antibodies against NR1-NR2 NMDA receptors; 60% of patients with anti-NMDA receptor encephalitis have the presence of a tumour (most commonly teratoma)
Aseptic Meningitis = meningeal inflammation with negative bacterial cultures.
Basilar Artery Occlusion: the clinical effects will be dependent on: adequacy of collaterals, integrity of the Circle of Willis and the onset of the occlusion; occlusion at the bifurcation will involve the posterior cerebral artery +/- the superior cerebellar artery
GBS vs Myasthenia Gravis vs MND
Brain herniation is the displacement of part of the brain through an opening or across a separating structure into a region that it does not normally occupy.
