Abstract

OBJECTIVE: The authors investigated whether striatal dopamine D2 receptor binding characteristics in vivo are similar in men and women and whether there are sex-related differences in the decline in D2 receptor density due to aging. METHOD: Striatal D2 receptor density (Bmax), affinity (Kd), and binding potential (Bmax/Kd) were measured with positron emission tomography and [11C]raclopride in 54 healthy subjects (33 men and 21 women). RESULTS: Women had generally lower D2 receptor affinity than men, and this difference was statistically significant in the left striatum. Bmax and Bmax/Kd tended to decline with age twice as fast in men as in women, but the difference did not reach statistical significance. CONCLUSIONS: These results confirm the age-related reduction of D2 receptor density and binding potential in both sexes in vivo. The lower D2 receptor affinity suggests an increased endogenous striatal dopamine concentration in women. This may have implications for the differential vulnerability of men and women to psychiatric disorders like schizophrenia and alcohol and substance dependence.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
