If your physician orders blood tests, a medical team member will draw your blood, usually through your arm, and send the blood sample to a laboratory for testing. Blood tests can be used to detect or rule out certain, but not all, neurological conditions. Your physician will determine if a blood test is the right type of test for your condition. Blood tests may be used to help diagnose or rule out:

• Amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease
• Alzheimer's disease
• Dementia
• Muscular dystrophy
• Neuropathy
• Dystonia
• Essential tremor
• Facial nerve disorders
• Headaches
• Migraines
• Concussions
• Myasthenia gravis
• Ataxia
• Tic disorders
• Wilson disease
• Vascular dementia
• Restless leg syndrome
• Sleep disorders
