How/where is the brain affected by copper accumulation?

Dr. Randy Burgettanswered
General Practice 9 years experience
Copper: Excess copper in the body is released in the blood and can accumulate in the tissues, particularly in the kidneys, eyes, and brain. When it goes to the brain, it usually deposits in nerves that are associated with movement, perception, and mood regulation. This causes a patient to lose coordination and become clumsy. Seizures, migraines, and cognitive defects may also result from excess copper.

Different from urine: The plasma test compared to the urine is newer and more sensitive. In other words if you have pheochromocytoma the plasma test is less likely to miss the diagnosis by coming back normal.
