Hi, Welcome to Health care magic forum.
Your brother is 56 years old, have mental
disability, parkinsonism, seizures, and
thyroid problem.
Recently he had difficulty in balancing,
incontinence, and bulging of the right eye.
Difficulty in balance might be due to the advance in the parkinsonism, spreading to the legs. The bulging of the eyes might be due to the fall of difficult gait. Incontinence could be due to the
urinary tract infection, or may be due to
neuritis.
I advise you to consult a physician for diagnosis and treatment.
Take more of green leafy vegetables, pulses,sprouts, and
protein rich foods.
Wishing for a quick and complete recovery. Thank you.
