a disease which metabolic failure of neurotransmitter between the neurons

cause by build up of amyloid that eventually builds up a mass of protein 

then it spreads through out the brain and progresses 

in general,the brain shrinks and room increases, there will be degenerative nervous system 

it has no cure, but can slow down the progress

and you won’t die from Alzheirmer’s but your organs will be weaken 

they eventually fail and lead to stroke, heart attack, pneumonia 

in terms of memory, you won’t be able to get them back once it’s gone

as it progresses it will damage not only the recent memory, but the memories of the past too

it’s like a chalk board getting erased starting from the recent one, eventually it will all be gone
