Cognitive Impairment in People with HIV in the European Region

CIPHER was a study in HIV outpatients to assess the prevalence of cognitive disorders, associated features and impact on risk behaviours.

It was based on a subset of the patients who have answered the ASTRA questionnaire. They were asked to undertake more detailed psychological tests in order to assess any HIV associated changes to neurocognitive functioning.
