Sara Hartley is 85 years old and has been a patient of the practice fo
r many years. She suffers from the early stages of senile dementia, bu
t remains fully mobile and otherwise well. She is cared for at home by
her unmarried daughter, Margaret, who works part-time for one hour ev
ery morning cleaning a neighbour's house. Sara is forgetful and has ur
inary incontinence, but is able to dress and feed herself and does not
wander or have inappropriate behaviour. One morning, you receive a re
quest from Margaret for a home visit because her mother has fallen and
injured her eye. On visiting, you find Sara sitting withdrawn in a ch
air. She has a black eye and bruising around the cheek on the opposite
side of her face. She says little and is unable to describe how she b
ecame injured. From the pattern of the bruising you do not believe tha
t Sara could have sustained these injuries from the fall which Margare
t describes. How would you manage this case?
