Despite the need for successful navigation, humans vary greatly in their ability to navigate, and these individual differences may relate to variation in brain structure. While prior research provides support for a correlation between hippocampal volume and navigation ability in both navigation experts and in older individuals, this relationship is under scrutiny for healthy, young adults. We assessed 99 healthy young adults' ability to navigate in a virtual, desktop maze and correlated their performance with total hippocampal gray matter volume.

Methods: This retrospective cohort study compared breast cancer incidence in patients with dopamine agonist (DA)-treated hyperprolactinemia versus matched controls in a 1:5 ratio.
Nonsexual acute genital ulcerations (NAGUs), also known as Lipschütz ulcers, are vulvar ulcers occurring predominantly in adolescent females. Although the pathogenesis is unknown, NAGUs are commonly associated with systemic infections. Here, we present a female child with NAGU along with disseminated Lyme disease.

Deficits in the lipid handling genes and are the most significant genetic risk factors for Lewy body dementia and related dementia syndromes. Parkinson's disease patients who carry both APOE4 and GBA1 variants have accelerated cognitive decline compared to single variant carriers.
