MEDI7212 Lecture Notes - Lecture 67: Anticonvulsant, Cerebellum, Focal Neurologic Signs
Document Summary
Fit (seizure), faint (syncope) and funny turn (lightheadedness/ dizziness) Foundation of consciousness - orientation in space and time ("where am i, what day is it?") Pitfalls (often missed: anxiety related/ hyperventilation, vasovagal syncope, postural hypotension, breath holding attacks (children, cardiovascular - arrhythmias, as, cerebrovascular - tias, neoplasia - sols, hypoglycaemia. Simple partial seizures: atypical migraine, cardiac arrhythmias, complex partial seizures, atypical tonic-clonic seizures, drugs/alcohol/marijuana, electrolyte disturbances, hypokalaemia, hyponatremia -psychogenic polydipsia or addison"s disease; take. Bp to distinguish via addison"s are very hypotensive. 7 masquerades checklist: depression, diabetes - hypoglycemia (sulfonylureas), hyperglycemic coma (bsl > 60mmol/l: drugs - alpha antagonists, anti-hypertensives, psychotropics (postural hypotension, usually olanzapine) and alcohol all cause hypotension, anemia, thyroid issues, uti. Is the pt telling me something: highly likely, psychogenic and communication disorders are common in this setting. Sudden change in behaviour due to brain dysfunction (electrical hypersynchronisation of cortical neural networks)
