Normally in a right handed person the left hemisphere is considered dominant. However, a new lesion in the left hemisphere can cause loss of this dominance so it is possible that this has occurred.

Alternatively, if the subject is now able to write using both hands concurrently but different material, it suggests that the two hemispheres are disconnected, the so called split brain syndrome which occurs with lesions of the corpus callosum. However, ambidexterity is not described in that syndrome.

Anyway, you need to consult your physician.

  • $\begingroup$ Nice that someone affirms that this can happen. The brain is a mysterious organ, and I agree that a brain lesion can cause this. It would be interesting to compare quality of writing in each hand. $\endgroup$ – anongoodnurse Mar 19 '18 at 23:35

You can't suddenly become ambidextrous. You can train yourself to use objects with the opposite hand, and become use to using your other hand.

Your body learns on repetition- Repeating something over and over till it becomes a habit. It takes time for your body to adjust to the change but you can become ambidextrous through training your body.

You just have to have the patience and the will to do it.
