My father is 71+ years old. He is a diabetic for around 30 years but has always been under strict control. Very active daily life. He recently started facing problems in walking, slow movements, inability to balance. He loses balance if he closes his eyes while standing. Head feels numb or heavy as if not allowing him to move/walk quickly.
So far we have made multiple visits to neurologists and surgeons. InItially diagnosed to be parkinsons but medication didnt improve the situation. Then stroke was suspected. MRI of brain and spine didn’t reveal any problems. Doctor checked for peripheral neuropathy since he is diabetic but that was not the case.
Symptoms didn’t appear gradually but started within a very short span of 3-5 days. Also the symptoms keep fluctuating every day. Morning he might be very slow and walking is difficult. Afternoon he is walking almost like normal.
My question is-
What else can be the cause of such symptoms, eapecially the lack of balance and coordination while walking? What other areas can the doctor look into?
Thanks and appreciate any help.
