The Psychological and Cognitive Landscape of Adult Idiopathic Intracranial Hypertension: A Scoping Review

Idiopathic intracranial hypertension (IIH) is a chronic headache disorder with increasing prevalence. Although characterized by raised intracranial pressure causing papilledema with a risk of visual impairment, psychological symptoms such as depression, anxiety, and cognitive impairment are frequently seen but are understudied and under-reported. Together, these can negatively affect quality of life. These were explored through a systematic PRISMA scoping review. OVID, EMBASE, Cochrane, and PubMed databases were searched in April 2023, limited to those in English and published during January 2000-March 2023. PROSPERO ID CRD42023399410.

From 454 identified studies, 24 relevant articles were identified from a range of countries including the United Kingdom, the United States, Israel, Egypt, Canada, Germany, and Brazil. Data on study design, participants, tests performed, and outcomes were collated. There is a considerable burden of psychiatric, affective, and cognitive conditions, as well as impaired quality of life, in adult patients with IIH. Notably, these were independently correlated with the presence of headache in a number of studies and with obesity in others.

Aside from optimizing symptom control, including reducing the severity of headaches and protecting visual function, clinicians should be mindful of the biopsychosocial difficulties and potential cognitive impairments patients with IIH face. Assistance may be required with managing concurrent depression and anxiety, as well as optimizing cognitive function. Incorporating neuropsychological assessment and individualized management strategies may be beneficial at the point of diagnosis and throughout the illness.
