Objective: 1. To investigate personality trait of patients with Parkinson’s disease (PD). 2. To clarify the relationship between personality trait and depression in patients with PD.

Background: In patients with PD, depression is known as one of the most frequent psychiatric symptoms. To understand of personality trait of PD patient is useful to support their depressive state for our psychotherapy.

Methods: Subjects were 98 patients with PD (male: female=51:47, mean age 68.5 years old, Yahr 2.9), who had been examined personality trait using the new personality test which was reworked the Yatabe Guilford personality test. The test buttery for depression is Geriatric Depression Scale (GDS). We compared the personality trait in patients with PD who conformed depression group (GDS>10) and non-depression group (GDS≤10). Based on the results of our previous study using the new personality test for PD, gender difference was revealed in personality trait. So, we analyzed the results with separating the sexes.

Results: There were no gender differences in age, age of onset, duration, and Hohen-Yahr severity scale in this study subjects. On personality trait, male showed higher self-display aggression and uncooperativeness than female (p=.001∼.010). Those results agreed with our previous study. 74% of male and 62% of female patients had depression. In male, depression group showed lower activity (p=.006) and higher inferiority (p=.030) and depressiveness (p=.038) than non-depression group. In female, depression group showed lower sociality (p=.017), older age (p=.012), later age of onset (p=.017) and higher aggression (p=.029), uncooperativeness (p=.002), inferiority (p=.007), nervosity (p=.002), and depressiveness (p=.003) than non-depression group.

Conclusions: In male patients with PD, depression(+) related with

-low activity

-a feeling of inferiority

In female, depression(+) related with

-advanced age

-elder onset of age

-low sociability and cooperativeness

-aggression and nervosity

-a feeling of inferiority

We will carry out further research using comparisons with normal aged control group.
