Objective: To investigate the clinical and familial characteristics of essential tremor(ET).Methods: The clinical features and familial history of 2 ET patients were reviewed.Results: The clinical manifestation of the probands was intentional tremor,which could be ameliorated by alcohol.The incidence of the disease was 55.6% and 43.7% among the first-and second-degree relatives of the two families.Propranolol,a ?-adrenoceptor antagonist,was an effective drug for ET.Conclusion: Clinically ET is characterized by postural or intentional tremor,which mostly involves the hands and head.Positive result of the alcohol test is shown in most ET patients.It is commonly assumed to be a genetic disease.

Objective To explore the risk factors of cognitive function in out-patients with depression in order to direct clinical therapy.Methods The clinical data of 180 cases of epileptic patients with depression from September 2005 to March 2009 were analyzed retrospectively.Results In 180 cases of epileptic patients with depression,82 cases(45.6%) of cognitive function were found,the occurrence with sex,marital status,the site of epileptic foci,the types of epileptic seizures were no significant correlation(P＞0.05),but related with onset age,educational level,disease course,the frequency of epileptic seizures and duration of attack (P＜0.05).Conclusion The risk factors of cognitive function in epileptic patients with depression were onset age,educational level,disease course,seizure frequency and duration of attack,it should avoid the occurrence of these risk factors and improve the quality of life of patients in clinical practice.
