abstract = {Emerging findings indicate that the hypothalamus, the
body's principal homeostatic centre, plays a crucial role in
modulating cognition, but comprehensive population-based
studies are lacking.We used cross-sectional data from the
Rhineland Study (N = 5812, 55.2 ± 13.6 years, $58\%$ women)
and the UK Biobank Imaging Study (UKB) (N = 45,076, 64.2 ±
7.7 years, $53\%$ women), two large-scale population-based
cohort studies. Volumes of hypothalamic structures were
obtained from 3T structural magnetic resonance images
through an automatic parcellation procedure
(FastSurfer-HypVINN). The standardised cognitive domain
scores were derived from extensive neuropsychological test
batteries. We employed multivariable linear regression to
assess associations of hypothalamic volumes with age, sex
and cognitive performance.In older individuals, volumes of
total, anterior and posterior hypothalamus, and mammillary
bodies were smaller, while those of medial hypothalamus and
tuberal region were larger. Larger medial hypothalamus
volume was related to higher cortisol levels in older
individuals, providing functional validation. Volumes of all
hypothalamic structures were larger in men compared to
women. In both sexes, larger volumes of total, anterior and
posterior hypothalamus, and mammillary bodies were
associated with better domain-specific cognitive
performance, whereas larger volumes of medial hypothalamus
and tuberal region were associated with worse
domain-specific cognitive performance.We found strong age
and sex effects on hypothalamic structures, as well as
robust associations between these structures and
domain-specific cognitive functions. Overall, these findings
thus implicate specific hypothalamic subregions as potential
therapeutic targets against age-associated cognitive
decline.Institutional funds, Federal Ministry of Education
