ABSTRACT

Objectives: To identify the cognitive and functional deficits in a well-characterized group of patients with vasculitis of the nervous system.

Methods: Sixty-seven patients diagnosed with Central Nervous System (CNS) or Peripheral nervous System (PNS) vasculitis over a 14-year period were retrospectively identified. Data on clinical presentation, laboratory, radiographic and tissue biopsy investigations, and treatment were collated. Cognitive, functional and quality of life evaluation assessments were performed in 31 patients who agreed to participate and included Addenbrooke’s Cognitive Examination-revised (ACE-R), Nottingham Extended Activities of Daily Living (NEADL) and EQ-5D-3L quality of life questionnaires.

Results: CNS vasculitis patients exhibited cognitive impairment, with a mean ACE-R score of 74/100 (standard deviation (SD) 16). NEADL and EQ-5D-3L scores were in the impaired range at 41/66 (SD 21) and 57/81 (SD 22), respectively. Patients with just PNS vasculitis exhibited fewer cognitive deficits with ACE-R and NEADL scores of 87 (SD 8) and 46 (SD 16) respectively. EQ-5D-3L score was in the impaired range of 65 (SD 22).

Conclusions: Vasculitis of the nervous system and, in particular, CNS vasculitis causes cognitive impairment and deficits in functional ability. Such patients should be targeted for cognitive rehabilitation.
