Sandra Dennis recalls moving into her father’s Englewood, Ill., home after he started showing signs of dementia in his late 70s. She recalls the mental and physical drain of caring for him, including a back injury requiring surgery.

Dennis, 65, lives in Richton Park, Ill., and tends to her daughter who suffers from health issues related to pulmonary hypertension. She tries to balance those duties with self-care, including keeping her shoulder healthy after a torn rotator cuff also required surgery.
