  4. The Role of the Hippocampus – H.M. H.M. Healthy Control

  5. The Role of the Hippocampus – Alzheimer’s Disease

  6. The Role of the Hippocampus – Alzheimer’s Disease

  7. The Role of the Temporal Lobes – Semantic Dementia

  8. Semantic Dementia (SD) Selective deficit to semantic memory that is associated with temporal lobe atrophy temporal lobe atrophy SD 1 Healthy Control SD 1 Control

  15. SD Individuals do relatively well on VISUOSPATIAL TESTS

  16. SD Individuals do relatively well on VISUOSPATIAL TESTS

  17. Individuals w/ SD do relatively well on VISUOSPATIAL TESTS

  18. SD Individuals do relatively well on NONVERBAL PROBLEM SOLVING TASKS

  19. Nonverbal Problem Solving - Raven’s Test

  24. Relating SD to language

  25. Differentiating SD from Associative Agnosia

  26. Associative Agnosia – impairment in assigning identity to a visually perceived object

  27. Associative Agnosia – impairment in assigning identity to a visually perceived object

  28. The Neuropsychology of Visual Pattern Recognition – Agnosia Associative Agnosia – impairment in assigning identity to a visually perceived object • Ratcliff & Newcombe (1982) • could copy anchor • could define anchor • could not ID anchor • could not draw from memory

  29. The Neuropsychology of Visual Pattern Recognition – Agnosia Associative Agnosia – impairment in assigning identity to a visually perceived object • Ratcliff & Newcombe (1982) • could copy anchor • could define anchor • could not ID anchor • could not draw from memory

  30. Associative Agnosia

  31. Semantic Dementia

  32. Semantic Dementia (SD) • How would you classify SD? • Establish poor performance on semantic measures • - e.g., category fluency, picture naming • 2. Establish relatively normal performance on • nonsemantic measures • - e.g., visual spatial, nonverbal problem solving • 3. Use MRI to establish temporal lobe atrophy SD 1 Control
