Started with signs of amnesia, mostly short term. About 2 years passed but behavioral changes were seen by family members. Could drive well, do coding well, but was not focusing on what was according to my plans. MRI showed swelling in brain. So,treatment with Acyclovir was done[Intravenous] for about 8 days and tablets for 5 days. No virus was found. Blood serum and water from spinal chord was sent to Barcelona. Only antibodies were found. EEG was OK. So was full body pet scan I am, as per my neurologist, taking Lamez 100 in morning, Valence 250 OD at noon, Libotryp and Lamez 50 in the evening. All seems well but once perhaps every day, for about 5 minutes, the environment looks a bit different. Especially at about 4 PM, sometimes later. I am well educated with high intelligence, 54+ years old. What can be my problem?
