Purpose: We aimed to assess the family caregivers' level of knowledge and attitudes about Parkison's disease (PD), identify factors affecting their knowledge, evaluate their quality of life (QoL) and factors influencing it and to define the effect of PD on activities of daily living (ADLs) of PD patients.

Method: We developed and validated a questionnaire to assess the level of knowledge and attitudes of family caregivers toward PD, effects of PD on caregivers' QoL as well as its effects on activities of daily living (ADLs) of patients from the caregivers' perspective. A scoring system was utilized and SPSS was used to evaluate the differences in responses between the groups; p < 0.
