Altered psychological standing as a consequence of Lyme disease

Clinicians take into account Lyme disease of their differential prognosis when an aged man’s psychological standing declines all of a sudden, although he had a historical past of dementia. The case was described in an article by Chabria et al entitled “Altered psychological standing, an uncommon manifestation of early disseminated Lyme disease: A case report.” [1]

 

An 84-year-old man was admitted to the hospital as a consequence of an altered psychological standing. He had a historical past of stroke and delicate to average dementia.

In response to his spouse, he had been having hallucinations 3 to 4 days previous to his hospitalization. And though he suffered from dementia, his signs had just lately worsened.

4 weeks previous to the onset of signs, the person had been vacationing in Maine, a area endemic for Lyme disease.

“Oral consumption had diminished significantly and he was discovered to have lower in practical capability,” Chabria wrote. Moreover, the affected person was agitated, confused and at instances mumbling incoherently.

He didn’t present any indicators of an an infection and his white blood cell (WBC) rely and temperature had been regular.

Nonetheless, the person had a small bruise on his arm, which his spouse attributed to an insect chunk, possible a ‘black fly.’ However this might not be confirmed. Due to this fact, clinicians opted to deal with empirically for Lyme disease.

“The presence of an atypical rash which seemed extra like a bruise prompted the authors to search for attainable central nervous system involvement in Lyme disease,” the authors wrote.

An EEG confirmed diffuse slowing in step with encephalopathy.

Take a look at outcomes revealed an elevated protein stage, and a WBC rely of 43/mm3 with 83% mono nuclear cells. Pink blood cells had been absent.

Based mostly on these findings, the person was handled empirically on IV Ceftriaxone.

“This case illustrates the significance of an index of suspicion for the prognosis of Lyme involvement of the central nervous system in a affected person who at baseline had dementia.”

Testing later revealed he was constructive for Lyme disease. And after a number of days of remedy, his psychological standing improved.
