alzheimers vs vascular dementia

what type of dementias are alzheimers and vascular?

alzheimers - cortical

vascular - subcortical

what is the best test to check the differences between alzheimers and vacular?

ACE-III

what is the effect of alzheimers on episodic memory?

- consolidation deficit

- rapid and severe fogetfulness

- impaired recall and recognition

what is the effect of vascular dementia on episodic memory?

- retrieval deficit

- recall impaired more than recognition

- slow forgetfulness - but almost approaching normal

what are the results for retrograde/remote memory in alzheimers vs vascular?

a - poorer for most recent events

v - intact

what are the changes in language and semantic knowledge for a and v?

a - prominent deficit

v - mild to no defiict

what can help recall semantic knowledge in subcortical dementias (v)?

phonemic cues (related to the sound of the word e.g. starts with S, rhymes with chair)

what are the changes in visuospatial abilities for a and v?

a - deficits common, later in progression

v - deficits common, earlier in progression

how are visuospatial copying tasks in alzheimers?

only show impairments later on in disease

what is the attention deficit in a and v?

a - mild to no deficit

v - prominent deficit

what are the working memory deficits in a and v?

A - mild deficit

V - prominent deficit

what are the executive functions in a and v?

a - prominent deficit

v - prominent deficit (but worse than A)

what is the difference in the onset of executive function deficit in a vs v?

a - mild perseverations, pervasiveness and timing more later in disease

v - severe perseverations, pervasive earlier on in disease

what are intrusion errors?

refers to false memories that have included a false detail into a particular memory

what are the intrusion rates in a compared to v?

a - higher

v - lower
