thanks for your query, i have gone through your query, the dislocated disc has no permanent treatment splints might help to some extent but since you are telling since 14years you have this problem you can get an MRI
done and see the movements and postion of the disc in closed and open mouth position...you can go for orthocentesis (intraraarticular lavage with autologous blood or saline) or surgical treatment
...but the prognosis can not be predicted.. consult a oral maxillofacial surgeon and physician....but i would like to suggest do not take stress
or tension because it aggravates tmj problems again which in turn gives tension so try to be cool and consult psychologist
for counseling...tmj disorder
has nothing to with memory problem....i hope my answer will help you... take care..
