It can also be some cognitive effect from a latent condition like MS.
Or any other neurological problem, really.
To put the blame on the meditation is a bit quick, in my opinion.
At most, the meditation maybe put some load on brain regions that were not accustomed to work to this intensity, but it isn't even required to explain the symptoms: could just be bad luck that the neurological problem occurred during meditation.
