Relationship between attention deficit hyperactivity disorder and temporomandibular disorders in adults: a questionnaire-based report.

OBJECTIVE

The symptoms of the attention deficit hyperactivity disorder (ADHD) persist in the adult years of life in most cases. They appear in adults with accompanying psychosocial problems. Temporomandibular disorder (TMD) refers to signs and symptoms associated with pain of non-dental origin in the oro-facial region, functional and structural disruptions of the masticatory system, especially the temporomandibular joints (TMJs) and masticatory muscles. The aim of the study was to show the relationship between the presence of ADHD symptoms in adulthood, in relation to the intensity of pain experienced in the face and problems connected to the TMD symptomatology, as well as sleep disorders.

PATIENTS AND

METHODS

The study group consisted of 252 individuals aged 18-55 years of both sexes, generally healthy. Each participant was asked to fill in several questionnaires, namely: ASRS (the World Health Organization ADHD Adult Self-Report Scale), DIVA (18 questions, 9 for concentration and attention disorders with an option in adulthood and childhood, 9 for hyperactivity and impulsivity with an option in adulthood and childhood), Athens Insomnia Scale, Stanford Sleepiness Scale (SSS), DC/TMD classification (Diagnostic Criteria for Temporomandibular Disorders - biaxial diagnostic criteria based on the biopsychosocial model).

RESULTS

Results show that when ADHD symptoms observed in childhood persist, personality disorders, social relations disorders and affective disorders are found more often in adults than motor hyperactivity.

CONCLUSIONS

There is a positive association between ADHD and the occurrence of symptoms of TMD in adults. This study confirmed this picture, extending it to include pain and sleep disorders.
