A neurologist is a doctor specialized in the branch of neurology.

, forms of dementia like Alzheimer's disease
, brain hemorrhage, or brain or medullary tumor (affecting the spinal cord). This specialization also investigates diseases of the peripheral nervous system, notably in cases of diabetes that have evolved into diabetic neuropathy
, or any other neural damage.
