PMID 33815021WHAT IT FOUND
A woman with left spatial neglect after brain tumour surgery tolerated prism adaptation during occupational therapy.
Some neglect measures improved, especially daily function, but one case cannot show the treatment caused the change.
Key findings
01She completed eight daily prism adaptation sessions during a 16-day hospital stay.
02Her Catherine Bergego Scale score fell from 16.6 at admission to 11.1 and then 7 during and after prism adaptation.
03She said she looked forward to the treatment and found the prisms straightforward and not overwhelming.

What it does not show
Only one patient was studied, so this cannot show whether the treatment works for other people. There was no control group or randomisation, and the authors say the improvement may or may not be due to prism adaptation. There was no follow-up testing after discharge. She did not complete the intended 10 sessions because discharge was scheduled. She had other medical conditions, including seizure disorder, daily smoking and diabetes mellitus, which may have affected recovery.

The easy way to misread this
Do not conclude that prism adaptation caused the neglect improvement. This was one patient, with no comparison group and no follow-up, so the change could have happened for other reasons.
