How does Alzheimers impact our Autobiograpical Memory?
Early damage to the hippocampus impairs retrieval of episodic details. Loss of semantic memory in the later stage.
Changes in the brain as a result of Alzheimers
Amyloid Plaque
Neurofibrillary Tangle
Brain Atrophy
Ways that can assist diagnosing Alzheimers
CT scan, MRI scan
