Q

What is Anterograde amnesia?

A

Brain trauma to the hippocampus

a neurodegenerative disease in the hippocampus and spreads to cerebral cortex

causes anterograde amnesia and cannot create new LTM

seen by worsening memory

Q

How does neurodegenerative disease effect memory?

A

damage and loss of neurons in brain disrupts storage and encoding of memories to LTM because there aren’t enough neurons to create a smooth process

this causes difficulty remembering or consolidating memories at all

Q

What biological symptoms are seen in Alzheimer’s disease?

A

amyloid plaques - build up of plaque around neurons which inhibits neuron communication

Neurofibrillary tangles - protein builds up and tangles in neurons, stopping transport of essential substances for the neuron, which kills it eventually
