Dementia
-a persistent impairment in intellectual fctn due to brain dysfctn. In this, a language dysfctn. of some kind can be present right from onset.
-this disease is more common in elderly populations.
-it may well be one of the more common forms of speech and language impairment you see.
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
