神経学者としてのレオナルド・ダ・ヴィンチ

Leonardo da Vinci as a Neurologist

レオナルド・ダ・ヴィンチは万能の画家であるが，医学，特に脳の研究にも情熱を傾けた。脳室を詳細に研究し，魂の在り処を追求した。彼に関する病跡学では，鏡文字の使用や注意欠如多動症と考えられることが注目され，非凡な創造性と仕事を完遂できない性格に寄与した可能性が議論されている。彼の死因は脳卒中と考えられているが，晩年に絵画を描けなくなった右上肢麻痺の原因としては尺骨ないし正中神経麻痺が推測されている。

Abstract

In addition to his versatility in painting and art, Leonardo da Vinci was extremely passionate about medicine, particularly the study of the brain. He investigated the ventricles of the brain in great detail in an attempt to locate the seat of the soul in the brain (senso comune). Pathography on Leonardo da Vinci suggests that his ability to use mirror writing and supposed attention-deficit/hyperactivity disorder may have contributed to his extraordinary creativity and tendency to be unable to complete his work. It is presumed that Leonardo da Vinci died of a stroke; however, it is speculated that ulnar or median nerve palsy led to right upper limb paralysis that prevented him from painting in his later years.
