FINAL EXAM- prognosis and recovery Flashcards
spontaneous recovery
occurs without behavioral intervention due to neurological changes and natural healing processes
recovery at behavioral levels
the ability to perform a previously impaired task in the same manner as before the injury
healing processes in spontaneous recovery
repercussion to damaged dissue
reduced cerebral edema
neuronal reorganization
absorption of damaged cerebral tissue
improvement of local circulation
spontaneous recovery timeline
most recovery occurs within the first 3-6 months, followed by a subtle and less dramatic recovery after the first 6 months, then minimal or no spontaneous recovery continues to occur
post spontaneous recover
occurs if treatment is targeted toward improving a certain behavior
compensation
the use of new strategies to perform the same task; the dominant strategy after structural and functional repair and restoration has reached its fullest potential; predominant in aphasia rehab
link between recovery and plasticity
degree of neural and behavioral plasticity can impact the degree of recovery & recovery can also impact plasticty
prognosis
a prediction about the course and eventual outcome of a disease or condition, usually based on clinical experience, intuition, and minimally on prognostic studies
prognostic variable categories
-neurological findings
-associated conditions
- patient variables
Neurological findings in Prognosis
-etiology of aphasia (hemorrhagic or ischemic)
-lesion size and site
hemorrhagic stroke
associated with more favorable outcomes than infarctions as they may displace cortical tissue rather than destroying it. these tend to occur in younger individuals
lesion size as a prognostic factor
though there is an assumption that size negatively impacts recover, studies have not definitively proven the negative correlation between size and degree of recovery, as well as negative effects on certain language skills
lesion site as a prognostic factor
unilateral strokes have a better prognostic outcome and centrally located lesions are more likely to result in a more severe and persistent aphasia
prognostic patient characteristic factors
age, family support, education, occupation, socioeconomic status, living environment, severity and type of aphasia, mental health, and other medical diagnoses
associated conditions
have an indirect effect on the recovery and response to treatment:
- pulmonary disease
- heart disease
- diabetes
- hearing loss
- vision loss
- paresis
