Thank you for posting your query.
Uncontrollable (or involuntary) head nodding could be due to partial (or focal fits
). It is not a generalised fit, as you would have lost consciousness if it was a generalised one.
Short duration of symptoms also favour the same.
For further evaluation, you should consult a neurologist
. You may require MRI
brain and EEG for confirmation of diagnosis.
