Memory

Question 1

What are the 2 types of memory?

Answer 1

1. Declarative- explicit= effort e.g. studying for neuro = facts = need effort
2. Non declarative- implicit= direct experience

Question 2

What types of memory loss are there?

Answer 2

Amnesia= when you lose memory/ cannot improve in your learning

• Limited Amnesia= most common due to trauma
• Dissociated A= rare, no damage to brain
• Retrograde= forget about things because brain tissue damage (trauma)
• Anterograde- you remember everything before your accident, cant remember anything after it.
• Transient Global A= suddenly forget everything post accident (sudden anterograde A)
  
  • Happens for a short time, due to low blood -> brain (ischemia) (someone punched you in the head real hard)
  • Symptoms: not organised sense (disoriented), repitition of same questions, in coming hours attacks will reduce, forever will have a memory gap/ loss
