يتأثر الشعور بالألم بطريقة تفسير الدماغ للإشارات الحسية والتجارب السابقة وليس بالإصابة الجسدية وحدها.
أظهرت تجربة أن التوقعات الذهنية قد تقلل من شدة الألم بنسبة 28% وتخفض نشاط مناطق الدماغ المسؤولة عنه.
قد يستمر الألم المزمن نتيجة التفاعل بين السلوك البشري وتفسير الدماغ، أو بسبب إصابات مستمرة أو تلف الأعصاب.
