alzheimers disease does not attack all types of memory equally. facts and personal life experiences are gradually lost, while some
___ memories, such as brushing their teeth, are retained.
subliminal
learned
implicit
hippocampal

Explanation:

For the first question:

• Concussion is related to chronic traumatic encephalopathy. Repeated concussions (head - traumas) have been linked to an increased risk of conditions like chronic traumatic encephalopathy, and there are also associations with Alzheimer's, depression, and suicide in some research. Amnesia is a symptom (memory loss) rather than a cause - related factor in this context. Genetics is a broader factor and not as directly connected in the way the sentence implies (the sentence is about an external factor related to trauma - like events). Drug abuse has its own set of associated disorders but not in the same trauma - related pathway as the listed diseases in the context of the question.

For the second question:

• Implicit memory refers to memory for skills and habits. Brushing teeth is a learned skill (implicit memory). Subliminal memory is related to stimuli below the threshold of consciousness. Learned is a more general term. Hippocampal is related to the brain structure (the hippocampus is important for explicit memory, which is the type that is more affected in Alzheimer's for facts and personal experiences).

Answer:

First question: concussion
Second question: implicit
