Thank you for posting your query at DoctorSpring.com. I have noted your symptoms.
Possibilities include brain ischemia (lack of blood flow to the brain) or demyelination (damage to nerve covering called myelin sheath). These can be confirmed or excluded by doing an MRI scan ofthe brain.
Another possibility to exclude would be a pinched nerve in the neck.
