This is such an interesting thing to read about!! Thank you for posting it! I have epilepsy following hemmorhaging to the parietal area affecting my motor movement, planning, and sensation. Much like the patient described, specific things in cognition 'space' will cause me focal sensations. Full tonic-clonic seizures are quite rare for me, but those smaller focal moments still occur. The feeling is one of my left side moving away from me, where my arm no longer feels mine, and I cannot move it as easily, the limb fades to a blur in my head, and moves in slow motion out of sync with my good side. These auras/focals/feelings occur most intensely when I'm overextending my brain cognitively, usually because I'm having a high-bandwidth conversation or am trying to solve a complex programming problem. When these onsets occur I know I need to stop and step away. Floppy arm = time to stop.
