My son had last attack of epilepsy 9 years ago. But his medicine is still on: Desval ER 500 in the morning and Desval ER 250 at night. If SGPT shoots up, Ursocol 300 twice a day. His TSH has recently shoot up 8.63. His EEG report is ok. His MRI scan of Brain & Hippocampi (Epilepsy Protocol) shows that both hippocampi reduced volume with paucity of interdigitations with diffuse hyperintensity on coronal FLAIR. Under this circumstance can we reduce his medicine (i.e. in the morning instead of Desval ER 500, Can we give him Desval ER 250? And how bring down TSH level?
