triad of normal pressure hydrocephalus(NPH)
cause of those symptomsWet,Wobbly and Wacky
compression of

6 types of brain herniation
characteristicssupratentorial
①cingulate(subfalcine) herniation
anterior cerebral aretery is compressed
②central herniation
Duret hemorrhage(rupture of paramedian basilar artery branches)
③uncal herniation
ipsilateral CN Ⅲ compression, contralateral crus cerebri compression against Kernohan notch
④transcalvarial(external herniation, 経頭蓋冠ヘルニア)
infratentorial
⑤upward herniation
almost same as transtentrial herniation
⑥cerebellar tonsillar herniation

akathisiamovement disorder that makes it hard for you to stay still (restlessness can be
extremely distressing for patients)
nonselective α blocker
drugs,clinical usephenoxybenzamine(for pheochromocytoma to prevent hypertensive crisis caused by β blocker, A before B)→irreversible
small cell carcinoma
hormone productionACTH→Cushing syndrome
ADH→SIADH
Antibodies against presynaptic Ca2+ channel→Ach release is affected→weakness on the lower extremities(Lambert-Eaton myasthenic syndrome) endocrinologyrespiratoryneurology Jun 27, 2019, 2:28 AM HirotoShishido
