A recent medical case highlights a critical lesson for clinicians and caregivers.
A 78-year-old Rhode Island man with mild cognitive impairment experienced a rapid worsening of confusion, gait instability, and yellowing eyes (scleral icterus) over just two weeks.
Because he already had memory changes, his initial decline was chalked up to pre-existing conditions.
However, after spending time outdoors on his property, he had contracted severe Babesiosis (with a high parasitemia burden of 27%) and disseminated Lyme disease.
“This case contributes to the growing literature describing atypical presentations of tickborne illness in older adults, particularly when manifesting as new or worsening cognitive dysfunction."
