To investigate the relationship between psychiatric symptoms and brain lesion site, thirty eight psychiatric inpatients with history of head trauma were selected. Patients were divided into three groups according to lesion sites ; patients with left hemispheric lesion (N=13), patients with right hemispheric lesion(N=11), and patients with ill defined lesion(N=14).
Psychiatric symptoms were examined focused on depression and cognitive functions. Depressive symptoms were checked by Hamilton Rating Scale for Depression(HRSD), and cognitive functions were checked by Mini-Mental Status Examination(MMSE) and Korean Wechsler Intelligence Scale(KWIS).
The results were as follows :
1) Patients with left hemispheric lesion, especially with left anterior lesion, showed significantly higher HRSD score than patients with another lesion sites(p<0.05).
2) Moderate to severe depression, whose HRSD score was higher than 18, was more common in patients with left hemispheric lesion than in patients with another lesion sites.
3) MMSE scores and KWIS scores of all three groups were not significantly different each other.
4) ‘Calculation’scores were lower in patients with left hemispheric lesion than in patients with another lesion sites.
5) ‘Language’scores were significantly lower in patients with left hemispheric lesion than in patients with another lesion sites(p<0.0.5).
