A brief comparison between AD and normal aging:
AD:
-Forget entire experiences (vs. parts of one)
-Rarely remembers later
-Can't follow spoken or written directions over time
-Notes become useless over time as reminders
-Eventually dependent on others in life
(vice-versa for regular aging)
---
-E4 allele of ApoE-4 protein greatly increases risk of AD, especially being homozygous for it.
(but not 100%, full effects still unknown - it's just a noted correlation)
-Physiologically, known to be caused by buildup of beta-amyloid protein in extracelluar space of the cortex and hippocampus.
(since the hippocampus is critical for memory and behaviour; particularly working memory, there you go).
(hippocampal overactivity is associated with schizophrenia, but that's another story,
)
---
No cure, treatment only slows progression:
-Cholinesterase inhibitors slightly increase cognition, by slowing the breakdown of acetylcholine
-Memantine, glutamate regulator
-Exercise mildly helps; increases neuron firing temporarily and NT release associated with the activity.
It's like endorphin release, though I don't really know the specifics of exercise therapy vs. AD, or if endorphins are even involved here, so maybe/maybe not put it down.
And that is all I remember for now.
SCHOOL'S OUT, BITCHES!
