BIOC14H3 Lecture Notes - Lecture 10: Mild Cognitive Impairment, Vascular Dementia, Transient Ischemic Attack
Document Summary
Slide 3: we define cognitive deficit to be 85 and below for iq, for diagnosis it has to be 70, and 70-85 is borderline deficit, below that it gets diagnosed as cognitive deficit. Slide 5: there is different types of de(cid:373)e(cid:374)tia . Their muscles become more rigid, they are slower and they get tremors: all these symptoms are common in alzhei(cid:373)er"s disease. But someone with ad have much smaller hippocampus They would have apoptosis so (cid:272)o(cid:374)(cid:374)e(cid:272)tio(cid:374) are (cid:272)ut off So the (cid:272)o(cid:374)(cid:374)e(cid:272)tio(cid:374) that the(cid:455) do(cid:374)"t use due to the disruption of communication would get killed off. So basically this would cause even the connections that are used to (cid:271)e (cid:272)ut off si(cid:374)(cid:272)e the(cid:455) (cid:272)ould (cid:271)e i(cid:374) the i(cid:374)ter(cid:373)ediate pro(cid:272)ess so o(cid:448)erall, disrupt the neuronal communication. So if they are stuck in these tangles, and the vesicles are also stu(cid:272)k i(cid:374) the ta(cid:374)gle .
