OBJECTIVE: De-novo psychiatric symptoms may develop within 3 months after a temporal lobectomy for epilepsy. The objective of this study was to identify presurgical risk factors for psychiatric symptoms. METHODS: Twenty-seven patients who had a temporal lobectomy for epilepsy were included. Twenty-four had hippocampal sclerosis or gliosis, and three had cavernous haemagiomata. Twelve had operations on the left, and 15 on the right side. Twenty-four patients were rendered free of seizures (SZ) with loss of awareness, three had early post-operative convulsions, one continued to have habitual SZ. RESULTS: Nine patients (33%) developed low mood, anxiety and emotional lability within 3 months after surgery. Patients with early post-operative psychiatric symptoms were younger (27.9/34.8 years, P = 0.01), and more anxious on the presurgical Hospital Anxiety and Depression Scale (12/8.44, P = 0.02) than patients without post-operative psychiatric symptoms. There was also an association between right temporal lobectomies and early post-surgical symptoms (P = 0.02 Fisher's exact test). CONCLUSION: Potential risk factors were age, anxiety and operation on the right side. Larger studies are required to determine if these risk factors are independent.
