What is "al-kaskari"

Al-Kaŝkarī (; fl. 930 CE) was a hospital physician from Baghdad.

In diagnosing mental disorder, Al-Kaskari used criteria such the temperament of the patient as indicators to ascertain the nature of the mental disorder: sluggishness and forgetfulness point to a cold temperament, which requires a different treatment from a warm one, which is revealed through insomnia.
