Geropsychological problems in medical rehabilitation: Dementia and depression among stroke and lower extremity fracture patients

Background. Although stroke and lower extremity fracture are often viewed a s distinct medical rehabilitation conditions, they share similarities in th at they are both experienced primarily among older adults, and are often ac companied by geropsychological problems such as dementia and depression. In spite of these similarities, actual comparisons of these prevalence rates have been rare in the previous literature, most likely due to obvious diffe rences in the nature of the injuries involved (neurological vs peripheral i njury). Methods. One hundred and one stroke and 198 lower extremity fracture patien ts were assessed with neuropsychological tests from the Normative Studies R esearch Project test battery. The prevalence rates of dementia and depressi on were then compared between these two patient groups. Results. Overall, 34.7% of stroke and 27.8% of lower extremity fracture pat ients met the criteria for dementia. In addition, 33.3% of stroke and 25.1% of lower extremity fracture patients scored in the depressed range on the Geriatric Depression Scale. The prevalence rates for dementia and depressio n did not differ significantly between these two patient groups. Conclusions. Although rehabilitation efforts focus mainly upon the primary diagnoses of geriatric patients, these findings suggest that stroke and low er extremity fracture should be considered within the context of the geriat ric issues (e.g., dementia, depression, and comorbid medical illness) which accompany them.
