The impact of co-morbid factors on the psychological outcome of tinnitus patients.

The study was carried out to determine the impact of some co-morbid otological symptoms and demographic factors on the emotional distress and cognitive functioning in patients with tinnitus. One hundred consecutive patients, complaining of constant idiopathic tinnitus, were enrolled into the study. Four tests were administered: Beck Depression Inventory, Hospital Anxiety Depression Scale (HADS, A--anxiety, D--depression), Mini-Mental State Examination (MMSE) and Trail Making Test (TMT).
