Diazepam Reduced Grooming Duration Without Restoring Its Pattern in a Shank3B Mouse Model
A behavioral study found that anxiety-like measures and repetitive grooming structure did not respond identically to diazepam. Total behavior time concealed differences in how the behavior was organized.

The model comparison
The researchers compared Shank3B knockout mice, an acute-restraint model, and a chronic-pain model. Diazepam reduced anxiety-like behavior and total grooming time in the knockout and stress models.
Grooming microstructure was not restored in the knockout mice, while aspects improved in the stress model. The authors interpreted the patterns as evidence of interacting but partly distinct behavioral processes.
Avoid a broad treatment claim
Mouse models capture selected features of complex human conditions. Camera angle and manual grooming analysis also limited measurement. Reduced duration is not equivalent to normalization of every behavioral component.
The study cannot establish that diazepam treats core autism features in people. Its practical interpretive value is to keep endpoints separate: an anxiolytic-like effect, a shorter repetitive behavior, and restoration of its organization are different findings. One favorable summary measure should not replace the complete behavioral pattern.
