Cognitive Impairment in People with HIV in the European Region

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

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

CIPHER is funded by NEAT (European AIDS Treatment Network).
