Abstract:
Objective To study the incidence of depression in essential tremor (ET) and associated factors. Methods Depression in 62 ET patients and 60 healthy subjects as control was evaluated by means of Hamilton Depression Scale ( HAMD ) , as well as Fahn-Tolosa-Marin Tremor Rating Scale (TRS) and Pittsburgh Sleep Quality Index (PSQI). Results Fifty-three point two percent(33/62) of ET patients and 11.7% (7/60) of healthy subjects were found to have at least mildly depression (HAMD score of 8 or higher), 35. 5% (22/62) of ET patients and 8. 3% (5/60) of healthy subjects fell into the mildly-to-mederately depression (HAMD score between 8 and 20 ), 17.7% (11/62) of ET patients and 3.3% (2/60) of healthy subjects were classified into moderately-to-severely depressed range (HAMD score between 21 and 35). There were statistical differences in ET group and healthy subjects group (X2= 23.898, 13.043, 6.649, all P <0.01). Additionally, there were statistical differences in anxiety/ somatization (t=-6.747, P<0.01), cognitive impairment (t=-2.017, P=0.05), block(t= -4.145, P<0.01), sleep disorders (t=-4.500, P<0.01) and despair (t=-3.591, P<0.01) between depression group and non-depression group. There were marked differences in PSQI total score ( t =-3.196, P=0.003 ), subjective sleep ( F1, t=-3.037, P=0.004), quality sleep latency (F2, t= -4.674, P<0.01) and sleep disturbances (F5, t=-2.594, P=0.013 ) between depression disorder group and non-depression disorder group. Meanwhile, the score of TRS, PSQI and sex were closely correlated with HAMD (β=0.589, P=0.000 ;β=0.469,P=0.000 ;β=0.256, P=0.027 ). Conclusions The incidence of depression is high in ET. Manifestation of depression are anxiety, reduced interest in work, sleep disorders, retardneas, inferiority complex, etc. The degree of symptoms relates to the severity of ET, sleep quality and gender.
