Types of dementia
|
Cortical:
-alzheimer's disease -Pick's disease (aka frontotemporal dementia) Subcortical: -Parkinson's disease -Huntington's chorea Toxic encephalopathologies*: - Wernicke-Korsakoff syndrome Infection (mimics fluent like aphasia) -Creutzfeldt-Jakob disease |

Cortical Alzheimer's Disease
|
-Dx usually made b/w 70-79 yrs
symptoms include: -intellectual dysfunctions sufficient to disrupt social behavior -memory impairment indication of brain damage and at least one of the following: -problems in abstract thinking -poor judgement -a disorder of higher cortical fctn. (e.g., aphasia, apraxia, agnosia) |

Language problems in Alzheimer's disease: Early stage
|
Early stage:
-sp. is fluent, syntactic and well articulated. -there are word finding problems (like anomic aphasia?) -they have problems naming, and use circumlocuations to try and find the word but can't use phonemic cues. Phonemic paraphasias are corrected. |
|
Language problems in Alzheimer's disease: Mid-stage
|
-language becomes increasingly paraphasic.
-more errors are not corrected. -there are neologisms. -comprehension is impaired. -it can resemble a Wernicke's aphasia or transcortical sensory aphasia |
|
Language problems in Alzheimer's disease: Late-stage
|
-there is a breakdown of pragmatic function.
-the pts are non-fluent, echolalic. -very impaired comprehension (sometimes like global aphasia, w/out the non-verbal cues) -their problems w/ 'pragmatics' seems to result from this being a more 'cognitive' use of language-relevence, context, conventions |
